Exclusive Product Features:

  • Real 300-Watt RMS output - The BMB DAS amplifier is designed to sustain a 300-watt output continuously without distortion or damage to the amplifier. Unlike other amplifiers in the market that may become damaged or cause music to sound distorted when reaching maximum output, BMB's amplifier is designed with much greater power and safety margins in mind so outputting at a constant 300 watts can be easily achieved without any problem.

  • Color 4.3" LCD Display - the screen allows users to clearly see and adjust all settings of the amplifier. Simple navigation menu makes changing any setting easy and quick.

  • Maximum Music Volume, Microphone Volume and Echo Level Limiter - this function adds a level of safety and limits the maximum output for music, microphone and echo volume. You can keep your speaker from being abused or avoid disturbing your neighbor if you don't want users to turn the music volume to full power! This function is also very useful if your speaker can not handle the full power output from the amplifier.

  • Initial Music Volume, Microphone Volume and Echo Level Setting - the pre-defined power-on setting allows the BMB DAS amplifier to reset at a default setting every time when turned-on without the equipment operators making adjustments for commercial establishments.

  • 6 Pre-Defined Music EQ and Microphone Echo Settings - Allow users to quickly adjust to the most suitable setting with a touch of button. Users can also save their favorite setting into one of the memory positions.

  • Key Controller: Adjust the key 6 steps up or 6 steps down to better match the music to the singer's voice

  • 10-Way Equalizer for Both Music and Microphone -  Users can fine tune their music using the 10-way graphic equalizer. At the same time, a separate microphone equalizer can let users fine tune their microphone as well

  • Built-In Auto Shut-Off Circuit - The BMB DAS amplifier has an internal monitoring circuit that is constantly checking all conditions of the amplifier. Whenever the circuit detects an unusual input, surge of power or excessive temperature, the auto shut-off circuit will immediately shutdown the amplifier to make sure neither your amplifier nor your speaker could get damaged

  • DAS-300 Offers 4-Way Sound Position Adjustment - You can adjust music balance between front to back, and left left right. This powerful function allows users to compensate for any irregular sized room or speakers to make sure the music comes out perfectly tuned.

  • Pure Amplifier Mode - this function allow users to disable all karaoke functions and use the DAS amplifier as a pure 150-watts RMS or 300 watts RMS amplifier.

  • Talk-Over Mode - Users can disable a 3rd microphone's echo function while the first two microphones can still be used for singing. This way, the 3rd microphone can be used for speeches, announcements or event hosting without echo and other effects.

  • Built-in RS-232 Port - Allow users to connect the DAS amplifier to a central system or a computer to control all functions.

  • Fixed or Auto Input Selector - This useful function allows the BMB DAS amplifier to switch to a background video and audio source when no songs are being played from one of the three input sources. Or you can connect up to three karaoke players and the amplifier will automatically switch to an active player based on its input priority and video or audio signal detection.

  • Water and Drink Spill Proof - The amplifier itself is completely sealed within the metal casing. Any accidental water or drink spilled on top of the amplifier could be easily wiped off because there is no fan ventilation that will allow any liquid to leak into the amplifier and cause damage.

BMB DAS-300 Mixing Amplifier

If you are looking for a quality mixing amplifier with quality DSP processing, this is the unit to buy. Yes, it cost more than other brands, but you get what you pay for. The unit is easy to use and easy to make adjustments. I would recommend anyone who cares about sound quality to buy BMB products.
Almost zero microphones feedback, even with the microphone directly pointing at the speakers at 1feet. Sounds great. Plenty of clean power. Quality toroidal power supply (isolated). Speaker posts do not allow for banana plug connectors. Gold color enclosure, I preferred black. No HDMI or fiber-optic audio input.

BMB karaoke amplifier

This unit seems well made. It provides lot of adjustment for music and microphone. You need to read instruction real well before attempting to hook-up speakers wire, it is not real straightforward. I had another cheap karaoke amplifier at $150 so this unit for sure is better. I think it is better than the idolpro amplifier IP-388 my friend has. It advertised the firmware can be updated but I see no connection beside the RS-232 port in the back. Who has computer with RS-232 port anymore ? The remote control is optional and you have to pay extra for it, that is a bummer, but it is nice to have it. I still have to play around more with it to get the best sound. I wish they had included the "Reverb" function for the price of this unit. Overall it is a good buy if you can afford it, you need to get good karaoke speakers as well to go along with this amplifier.

Iím very pleased with this amplifier. I bought before a Voco.. something and what a piece of crap; even with an exchange for a new one still it was a waist.
This amplifier actually honors its price. It is very simple to use, is very reliable and looks good!
Reliability No center speaker connection out. No fiber optic connection.
