VocoPro DVX890K Karaoke Player Review

VocoPro is a professional audio company and is very well known for their high end professional karaoke machines. They are located in California and the company has been in business since 1991. They are reputable for their great customer service. If you are looking for a higher quality karaoke machine with a decent price, this is a brand that you should consider as an option.

This system is a multi-format karaoke player that provides a high degree of media compatibility. It comes with 2 microphones, full function remote control and can connect to various audio and video systems such as TVs, amplifiers and receivers, mixers, subwoofers and surround sound system in general. Being USB and SD card compatible, it allows you to access your digital music library.

This review will cover all the features offered by this karaoke machine. I will give you all the pros and cons as well as a summary of tons of reviews I read through for this system. After reading my detailed review, you will feel more comfortable and less overwhelmed by all the options and features offered by a higher quality karaoke machine like VocoPro DVX-890.

Type of Usage


This VocoPro Karaoke system has a professional looking and is a great choice for hobbyist and more advanced users looking for more options and complete features. That said, beginners and karaoke fans seeking for a higher quality for a very reasonable price can benefit largely from the versatile feature set that this karaoke machine has to offer. Also, I would recommend this one for those who are more serious about singing and/or are taking some vocal training online or practicing to improve their vocal range and hit higher notes.

This system also features brackets for mounting the player into a 19-inch rack case. Moreover, the machine can be used both for home use, outdoor parties as well as in professional settings.

The VocoPro karaoke system works with 120V/240V and is NTSC/PAL compatible for worldwide use. This is a very cool feature that not many karaoke systems would offer.

Karaoke Microphone

Two microphones with very decent quality are provided when buying this system. The karaoke microphones come each with a 15ft cord that gives the performer some freedom to move around while singing. Two separate microphone jacks are also provided so you can use your own set of microphones if you so desire. This is especially applicable to hobbyists looking for higher quality microphones.

Note also that, if for any reason you would like to use wireless microphones, this is a possibility. What you need is to have the cables to connect your karaoke machine to your wireless microphone receiver. In case you decide to do so, I would recommend a VocoPro UHF-28-7 Wireless Microphone System.

Monitor / Display

This karaoke player does not come with a built in monitor or display. However, as we will see later in this review, you can hook up this machine to a TV or monitor using various types of connectors with no issue. This is covered later in the review.

Song source / Player

The VocoPro DVX890K comes with a mutli-format disc player which is compatible with the following formats:

DVD: this means, you can use this system as a generic DVD player

DivX: this is a popular MPEG-4 based video compression technology that would allow you to have same quality Video as the DVD format but in a much smaller size (about 1/10). This means you can have a full movie or tons of karaoke files on a single CD. This technology combines the video with high quality AC3 or MP3 audio. If you are into downloading movies and videos online, you will love this feature as it practically resolves storage issues without compromising quality.

VCD: this is a technology older than DVD and Blue-ray to store video on a compact disc

CD+G: this is standard karaoke format that contains the sound as well as video (G stands for graphics) which is essentially the lyrics you can stream on your TV and/or monitor.

MP3: a typical digital technology used to compress audio files. This is the format used by MP3 players that most people use these days

Photo-CD: a digital technology developed by Kodak a while ago to store high quality images on a CD.

DVD +/-R: these are basically DVD formats with some subtle differences that I would not worry much about here as they are beyond the scope of this review. The main take away is that the player is essentially compatible with most media formats that you can imagine.


This karaoke machine does not come with built in speakers but provides audio outputs to be connected to your surround sound systems or speakers. This can be done through your surround system receiver for instance. The output audio signal quality is very good for those who are picky about this and would like to use high quality speakers.

Recording Options

The VocoPro karaoke machine does not provide recording options.

Voice Controls

The VocoPro Karaoke Machine offers a wide range ( +/- 8 step) of key control to change the key of the music to adapt to your vocal range. This can be done through both front panel and remote control.

Audio/Video Input & Outputs

The rear panel of this professional karaoke system provides you with plenty of audio and video connections. Here is a summary of the inputs and outputs that you will get with this karaoke machine:

Video Connections

HDMI output: this means you can establish an HD connection to your TV. As an example, if you are using the karaoke function, you can see lyrics streaming on your TV while you are singing along. Most home karaoke machines would not provide HD capability when connecting to TV.

Component Video ( Y / Pb / Pr): this means connection to your TV or monitor through component video cable. This is a standard video connection that provides color components (Pr and Pb) as well as luminance (Y). For more geeky ones, the luminance is a measure of light intensity per unit area and for the rest of you guys who don’t care too much about these technical details: nothing to worry about, this is just a component of your video information transferred from your system to your TV/monitor, that’s pretty much what you need to know about this.

Video out (RCA) jack: this is to carry composite video and used to interconnect with another video device. As an example, you can use this jack to connect your VocoPro karaoke machine to a monitor.

S-Video Jack: yet another way to connect your machine to a second video system if you have an S-video connector. In this type of connector, the luma component is the same as in Component video but the other two components are combined into one.

Few words about various video connections:

As you may have noticed, this karaoke machine provides you with a lot of options in terms of video connections. This is a benefit but can sometimes be confusing and overwhelming for consumers wondering what is the best connector to use and to connect to what system etc.  The choice between these connections is really a matter of price/performance and also availability of corresponding plugins on your other video device that is to be connected to your karaoke machine. As an example, if you simply have a monitor with just one RCA input for video connection, then the choice is obvious and you know already you won’t need to go after buying an HDMI cable for instance. So, before getting yourself confused and wonder what connector to buy, you need to make sure what availability you would have by checking out the video device you want to connect to.

Video ConnectionsIn general, a simple RCA video connection is a composite video in which all the components of video information are bundled together. This is the connection with the least quality among other types you would have with this karaoke machine.

This is contrast with the component video, where the video information is divided into its three components (one is luminance and there are two color components). Component video connectors offer a higher quality signal than the simple RCA video connectors.

Now here comes S-video connection which is something midway between composite video and component video connections. As mentioned before, in the case of S-video, the luminance component is the same as in component video and the other 2 color components are combined together.

You notice a rule of thumb here, the more you bundle the video components together, the less quality you will get and as a result, component video is better than S-video in terms of quality and the composite video has the worst quality among the three.

All that said, the latest technology is HDMI which normally carries both video and audio information. The HDMI connection provides high quality video and audio and is the best among all other types of connections mentioned above. If you have a High Definition TV with HDMI connection, the best choice for video transfer would then be to just use the HDMI connection.

As mentioned previously though, the Microphone vocals are only output from the MIC and MUSIC OUT and therefore, as opposed to what we would expect, the vocals are not transferred through the HDMI connection. This is something kind of misleading with this product and you need to pay attention to when building your setup.

In the following table, I have included a picture for each connector. This is for your reference so you can use when buying the right connector for your setup.

Optical Audio
Composite Video
Component Video


5.1 Channel Audio Output: this is essentially referring to your 6 channel surround system. Two front channels (left and right), one channel in the middle and two (one left and one right) in the back. The “.1” refers to the bass channel (Subwoofer). What this means is that there are 6 outputs to setup and connect with your surround system.

Digital Coaxial Audio Output Jack: this jack is used for digital audio interconnection. Note that this is not the same as the coax cable used for antenna or TV feed connection and alike. A digital Coaxial Audio connector has RCA type of connector at both ends and this type of cable is designed to carry high quality audio.

Digital Audio Output jack: this jack is used to connect your professional karaoke system to another audio device using optical cables. See below for the comparison of this type of connection with Digital coaxial audio connection;

Scart Out: this is used for connecting to Eurpean TV systems.

MIC and Music Out (Mixed Out) jacks: this where the analog audio is output allowing you to connect to various Audio Video devices such as TV, receivers, etc. Note that vocals and music are output at the same time through these jacks.

Digital Coaxial audio vs. optical audio (which one to choose):

The vocopro DVX-890K DVD karaoke player offers two different types of audio connections. Consumers ask me regularly which one is better to use, when and why? I keep saying there is no very clear cut answer to this type of question as it’s always a matter of tradeoffs and pros and cons. Some criteria that are important to you, may or may not appear to be that important to another consumer. That’s why in this section of my review, I decided to explain a bit about these two audio connection types to help you make a better and more informed decision about how to go with your setup.

Digital Coaxial Audio Cable: this cable looks like a typical RCA cable. As opposed to generic coax cables, the signal here Audio Connectionis transmitted digitally and not in analog fashion. Due to extra shielding, the cable is thicker and it also offer a higher quality audio. Because of the design and higher quality, this type of cable is more expensive than typical analog RCA cables.

Digital Optical Audio is a technology wherein the audio information is transferred using light and via optical fiber. In this cool technology, the electrical signal is turned into optical signal within the transmission module and the optical signal travels the optical wire to the receiver. Inside receiver, the reverse operation takes place, in other words, the optical signal is transformed back into electrical signal.

You may ask why all these hassles? Why on earth we would like to complicate our lives with electrical to optical and the reverse transformations? The answer is simple. Copper wires in general and no matter how they are designed are lossy. For the same distance used, the optical cables are virtually lossless and suffer less than copper wires from the loss issue.

Also, another issue with copper wires is the so called EMI (Electromagnetic Interference). These are radio frequency interferences that potentially degrade your signal quality when using copper based audio cables. The EMI issue is virtually non-existent in the case of optical fibers. Although optical audio cables offer an excellent clarity of sound, they have their own share of shortcomings. Oftentimes, due to material used, the optical cables are brittle and can be easily damaged by severe bending and carelessness of the user. This issue can have a negative impact on the optical signal and makes it “jittery” and this in turn results in quality degradation.

So which one of these cables is better? Depends on who you ask? Optical cable lovers claim that the jitter issue is not even noticeable and these cables offer much higher quality. On the other hand, there are copper wire fans that don’t agree and prefer the signal quality when using digital coaxial cables. They just like that fact that these cables are more resistant than optical ones and break less often.

The reality is, both these cables are known for their high performance and you need to probably use both at least once and see which one you prefer. Again, at some point, it becomes a matter of tradeoffs. But now that, through this review, you know more details about how these two different technologies works, you are better equipped to make a better choice if your setups allows for having both options.

Connectivity and Media Compatibility

Now that you are more familiar with the audio/video inputs and outputs that come with your VocoPro karaoke machine, let’s see how we can use this system as part of different setups.

As you can imagine, depending on what you are trying to achieve, you can come up with many setups where you can use this karaoke machine. In order to give you some ideas, in the following diagram a generic setup for such karaoke system is shown.

Professional Karaoke Machine

Note that the only way to get the vocal out, is to use the Mixed out jack on the rear panel of this karaoke machine.

Referring to the setup above, the music and vocals from the karaoke player can get mixed with other possible devices (musical instruments for instance) through the mixer. The output of the mixer is hooked up to an audio amplifier which in turn will drive your audio speakers or surround system.

You can also, hook up your karaoke player to your TV and this will enable you to see lyrics streaming on your screen while singing along the music. This is just a typical setup for a complete karaoke system but you don’t have to have all this bits and pieces to be able to use your VocoPro karaoke player.

Here are some other examples of typical setups wherein the VocoPro karaoke machine could be used:

One can bypass the mixer in the previous setup and connect the mixed out jacks directly to an audio amplifier. In this setup, the amplifier can be output to either stereo speakers (L/R) or a 5.1 channel surround speakers.

If you are using your system as a DVD player for instance, you can use the 5.1 channel audio output to hook up directly to the receiver in your home theatre system.

You can connect the player through various video connections to a TV or a monitor, depending what types of connections are available in the mentioned video devices.

You can also simply connect this system (audio and video) to your TV where the TV speakers would be used for the sound and obviously the screen will stream Lyrics. In this setup you won’t need any additional devices such as separate speakers or audio amplifiers etc.

Note that this system cannot accept an MP3 player or smart device (such as iPod) as a source player. If you are looking to play your digital music library, you would need to use the USB connection or the SD card.

USB and SD card compatibility

This professional karaoke machine offers both USB and SD card ports. If you don’t want to carry around several discs containing your music, you will love this feature. Simply dump all your music on one of these memory devices and you are good to go with this karaoke player. Great option to use with your digital library!

Special Effects – disco lights, etc.

This karaoke player does not come with disco lights.

Power – Batteries or plug-in

This professional karaoke machine does not work with batteries. This machine works with 120V/240V.

Karaoke Player Control Panel

The control panel comes with plenty of useful functions. In order to give you an idea of what you can achieve with this system, I have summarized the control panel functions in below. As you can see, I have provided a little explanation of the functions that are non-obvious and the other ones with no description are pretty much self-explanatory:

Power button

Audio Button – enables switching between AC-3, AC-3 2 channel and 5.1 channel output. Let me note that this karaoke player is equipped with built-in Dolby digital AC-3 and DTS decoder for higher sound quality. In order to avoid overwhelming this post with technical terms, I will dedicate a separate post for all this. For now, all you need to take away is that this system can provide cinema sound quality using various format, which is a great thing, isn’t it?

Display Window – shows tray disc status and time display

L/R: four playback modes for multiplex CD+G’s are available through this button

Remote Control

The VocoPro DVX890K comes with a versatile remote control offering various functions when operating the machine as karaoke and DVD player or when using the USB and SD card. As opposed to a lot of manufacturers, VovoPro has done a great job in terms of the completeness and clarity of the content provided within the manual coming with this system.

I have read this manual in detail and was impressed by the detailed information provided therein. The comprehensive manual actually explains clearly and in detail what each and every button on the remote control would do as well as various modes of operations of the karaoke machine.

Consumer Reviews

I have been particularly curious about this system and have read probably every single related review online. People are generally very pleased and impressed by the versatility and superior quality of this VocoPro Karaoke System. Several reviews mention that this is a professional karaoke machine that you can use at home for a reasonable price.

Many consumers have also been happy with the microphones received with their purchase. As I said before, this is not clearly mentioned anywhere in the product description and has been the source of a pleasant surprise for many buyers.

The USB and SD card also seem to have been a winner and it appears that this feature has been very useful for some. Some consumers seem to also like very much the remote control offering a broad range of functions and features.

There seems to be some complaints about a minor delay between when you sing and the instant the sound would come out of the speakers. I noticed a few reviews that had mentioned this and the buyers were not happy with it. As for any other product, some people had poor out of the box experience where some features would have not worked. That said, returning the product and/or replacing it addressed the issue for the majority of the cases.
