The Singing Machine iSM990BT Review


This karaoke machine is one of the best and latest from Singing Machine. It offers nice features and the one to mention here is the Bluetooth capability. Wireless connection to your source such as an iPad, iPod or similar MP3 player is an extremely cool feature which makes anybody’s life easier. All in all, a great product with all the required features and a descent price.

Read through my Singing Machine iSM990BT review given below and you will thank me later for it. I have not left any stones unturned and you can get all the information you need from this in-depth post. Drop me a line if there is any specific question in your mind and I would be happy to help so you can make the most informed decision before buying a karaoke machine.

Type of Usage

This is a portable device that weighs only around 8lbs. This means you can use it anywhere and it’s easy to take it from one place to another. Adults, kids and the whole family can have fun with this one and it has all the features that keep everybody happy.

For the size, the speakers are quite powerful, 10W, and they can do the job easily for a 15-30 people gathering. Ideally, you may want to use this inside. That said, I don’t think you would be disappointed to use this machine outdoors for a relatively small gathering.

This machine is ideal for birthday parties, company parties, restaurant, indoor gatherings etc. It is also easy to setup and almost ready to use out of the box.

Microphone

This Karaoke Machine comes with one wired microphone. However, there are two inputs for mics and therefore there is possibility to use a second one .

Just note that, the second microphone must be bought separately . Most people go for it as a second mic makes singing duets a possibility and in general it’s more fun to sing together with a nice karaoke song. If you have been to any karaoke party before, you understand what I am talking about. The addition microphone makes a ton of difference, I am sure you would agree with me on this one.

Monitor / Display

This karaoke machine does not come with a built in screen. But no worries, as you can still hook up this machine to your TV. It’s very easy and straightforward. This is done the same way as you would connect most DVD players, video game consoles, video cameras and alike. The system comes with a standard RCA cable offering three connectors (one video (yellow) and two audio for left and right (white and red)). Just connect the corresponding outputs (Video and Audios) of the machine to their respective inputs of your TV and that will take care of your hook up. If the audio jacks are not connected, the audio will just come out of the device speakers.

This is a very convenient feature for gathering where the crowd are singing along and there is a need for a much larger screen. The bigger your screen, the more people can see, the more fun would that be.

Song source / Player

The iSM990BT karaoke machine is versatile and allows the users to source songs from the followings:

CD – with or without MP3+G files

What the heck is MP3+G, I am sure you may be wondering? Well this is the newest format for karaoke music utilizing the MP3’s small file size. All you need to know is that it will display music on your screen. That’s all there is to it. For more geeky ones, if you want to know more and have questions, drop me a few lines in the comment section and I personally will answer your question, promised!

CD+G (CD + Graphics): these are very similar to regular CD’s but they also carry lyrics information which will stream on your TV screen. The connection to TV was covered thoroughly in the previous section, please take a look at it if there are still related questions in your mind.

USB drive: this is a great feature that this karaoke machine offers. I have studied and played with so many machines out there and there are not that many that would have USB drive connection. That will allow you another great song source with a high capacity.

The Singing Machine iSM990BT is a Bluetooth Karaoke System

If there is one take away from reading my Singing Machine iSM990BT review, this would be it. Very exciting feature, isn’t it? This machine streams music from any Bluetooth compatible device. That’s a great feature all consumers are very happy with as it offers so many possibilities. Again, there are not that many karaoke machines out there that I know of, and believe me I know most if not all of them, will offer this feature.

Just switch on the Bluetooth function of your device and you will see “Singing Machine” appear on your device’s search list. Pair them up and you are all set.

One important tip so you don’t get stuck for no good reason. If your Bluetooth device prompts you for a pass code during the pairing process, just enter “0000” and you should be good to go. Trust me, just do this and they will be paired for as long as you would like them to.

Last but not least for the more technical ones, the Bluetooth is specified to function within 30 feet (10 meters) measured in open space.

Speakers

The Singing Machine ISM990BT Bluetooth Karaoke System comes with built in speakers offering 10W of power. This is a descent power for medium size gathering. I have read probably all the online reports and reviews and my collection is that the sound quality of this machine is good and among one of the best compared to the similar systems.

Various features

features-250x400-2Here are the main features all in one place mostly for your convenience:

  • CD player
  • Cradle – the adjustable cradle is designed for convenience. Your Bluetooth device, iPod, iPad or alike can be conveniently placed in the cradle after being paired. It sounds obvious, but believe me most of the machines don’t come with this which is a pain in the neck as you have to always find a place to put your device. With no cradle it will end up on the floor beside the machine … ugh…
  • Digital Display
  • USB Port – used as an additional song source
  • Line in jack – to connect the external device, iPod, iPad etc
  • Master Volume control
  • Mic Volume control – allows independent Mic volume control
  • Mic 1 Jack
  • Mic 2 Jack
  • AVC, Balance and Echo Contrls
  • Pairing Button – for Bluetooth connectivity
  • Built in speakers
  • Handle – located in the back of the system and makes it very easy and convenient to carry
  • Bonuses – comes with 5 Bonus Songs Download and 6 Christmas CDG collections which are ideal for holiday times

Recording Options

This karaoke machine does not offer any recording option. If this is very important for you, take a look at Karaoke USA GF829 and/or Karaoke USA GF830. They are closely similar to this one in terms of general functionality and features and they offer recording options. These might be your best bet if recording capability is a must for you.

Voice Controls, Balance Control, Digital Echo?

This system comes with standard voice controls which are listed below:

Auto Voice Control (AVC): this works with multiplex recordings only. When on, the vocals will be muted as soon as the you are singing in the microphone and they are automatically back (unmated ) when you stop singing. This is one of my favorite features and I have tons of fun with it. You have to use it at least once to see what I mean and understand how much fun it is to use the machine in this mode.

Balance Control: you can eliminate completely the lead singer, the music or something in between depending on the position of the corresponding knob. This is also a standard feature that comes with most machines and adds some more fun to the mix.

Echo Control: This allows you to add echo to your voice and adjust its level. An additional nice feature that especially kids love to play with and have fun.

What people are saying, Consumer Reviews

I have read all Singing Machine iSM990BT reviews you can find anywhere online. Actually, I have had the opportunity to play with one. A close friend owns one which is used for gatherings.

Here is a very summary of my findings. I have gathered them all here to make your life easier and to help you make a better decision before purchase.

Karaoke Machine ReviewConsumers are mostly happy with the Bluetooth connectivity feature. There are many instances where people mention the loud and high quality of the sounds/speakers – that’s a good thing as this is generally a weakness for many karaoke machine models manufactured so far.

The machine is agreed to be suitable for the whole family and gatherings. People seem to like the nice slot/cradle for the iPad and find that very practical. Some are happy not to have to purchase CD’s songs and are happy to use the iPod/iPad connectivity. They state the combination of that feature with free Youtube videos is more than enough for what they are looking for.

Some consumers seem to complain about the loose mic connections. There are also some fair complaints about the fact that the machine cannot operate with batteries. This definitely reduce the portability of the machine but certainly not a deal breaker.

The microphone coming with the machine is wired and not wireless and this seems to have disappointed some buyers.

  • Bluetooth connectivity
  • Adjustable cradle
  • Two microphones when the corresponding model is purchased
  • High quality and powerful built in speaker
  • Connectivity to TV
  • iPod, iPad and smart device compatibility
  • Handle for better portability
  • USB connection
  • Very easy to setup, plug and play out of the box

Cons

  • Not functional with batteries
  • One of the models comes only with one microphone
  • No built in screen
  • No disco lights or visual effects
  • No recording options
  • No remote control

The Singing Machine iSM990BT Price

This machine is offered for a very reasonable price given the features and versatility it offers. The highlight is the Bluetooth connectivity which is a great differentiator for this system compared with the machines within the same range. Two models can be purchased, one comes with one microphone and the other one with two. For the small price difference, I definitely recommend to purchase the model offering two separate microphones. This will erase the headache of buying a second microphone yourself. If you are looking for a nice, portable, compact and high quality karaoke machine for both adults and kids, this one has to be on top of your list.

There you have it. Don’t forget to send me your comments and questions and I would be happy to get back to you very quickly. I personally respond to every single email and comments coming my way. Enjoy your karaoke machine and have fun singing.

  1. Can you display a youtube karaoke video on your TV when your iPad/iPod/iPhone is connected to the iSM990BT via Bluetooth?

    1. Hi Mike,

      Great question. Connecting your iPad/iPod/iPhone to ISM990BT via Bluetooth would only allow you streaming audio and the YT video in this case can only be seen on your smart device and not on TV. There are two ways to use the TV screen together with this karaoke machine: 1. CD+G by using the CD+G player 2. MP3+G and USB: you can download songs with MP3+G format from the Singing Machine store and then save them on your USB and use that connection together with your TV to get the sound as well as lyrics streaming on your TV screen.

      Hope this helps and please let me know if this is clear or if you need more information.
