    Commercial Audio 4x120W 4ch/4Zone Mixer Matrix 100/70V w/Digital Media Player (No Logo)

    Simplify the task of running distributed audio for restaurants, hotels, or anywhere large areas need background music and/or paging address systems. Connect hundreds of speakers covering acres of area without the need for large equipment racks.

    A constant voltage speaker system differs from a traditional 8-ohm speaker system in that it uses a step-up transformer at the audio source to raise the voltage and lower the current on the transmission line. At the speaker end, a step-down transformer converts the signal back to a normal speaker level voltage. This reduces power loss during transmission, which allows for the use of longer speaker wire runs using smaller gauge wire.

    Additionally, a constant voltage speaker system allows for the use of multiple speakers on each channel, without the need for complicated impedance calculations and configurations. In a constant voltage system, all speakers on a given channel are connected in parallel and the complicated impedance calculations are replaced by simple wattage calculations.

    For example, if you want to connect two speakers per channel in a traditional 8-ohm speaker system, you must either connect them in series, which results in an overall 16-ohm impedance, or in parallel, which results in an overall 4-ohm impedance. In the first case, the 16-ohms impedance effectively halves the output power of your amplifier, resulting in lower overall volume levels. In the latter case, the 4-ohms impedance means that your amplifier will have to work harder and must be rated as stable at 4 ohms. Adding a third speaker to the mix would complicate it further, producing either a 24-ohm or 2-ohm overall impedance. Note that very few amplifiers are stable under 2-ohm loads, so that is usually not an option.

    On the other hand, with a constant voltage system, you consider first the RMS output wattage of the amplifier. This should be reduced by 20% to compensate for insertion loss. For example, if using a 100-watt amplifier, the total load from speakers should not exceed 80 watts.

    This amp features three combination XLR/TRS balanced/unbalanced inputs, which can be set to accept a standard microphone input, a microphone input with +48V phantom power, or a line level input. It also has two unbalanced stereo RCA line level inputs. It has four independent 120 watt amplifiers, which can drive 4-ohm loads or a 70V or 100V constant voltage speaker array. A Media Player is included, which features a built-in FM tuner and an mp3 player, which can playback files from a drive connected to the USB port or an SD™ card inserted in the SD/MEDIA slot. It includes thermal, short-circuit, clipping, and overload protection circuits, as well as a ground lift switch. It can interface with external phone systems for telephone paging.

    Features:

    • Four independent 120-watt amplifiers capable of driving 4Ω loads, as well as 70V and 100V constant voltage speaker arrays

    • RS232 serial control
    • Can interface with external phone systems for telephone paging
    • Thermal, short-circuit, clipping, and overload protection circuits
    • 1-watt, 8-ohm amplifier for driving a monitor speaker
    • Ground lift option

    BEST ANSWER: Thank you for your question. You would be able to use the 15699 speakers, however, you would have to wire the speakers in parallel but you would only be able to have a total of 8 speakers. If you wished to use the 18802 amplifier, it would be best to go the route of utilizing it as a Constant Voltage system. Which would require speakers like Product # 14887.

    Should you require additional assistance, please reach out to our technical support team with a detailed question via any of the methods available here:

    Is there any cheap way to adjust the volume remotely?
    IT Department A on Aug 9, 2017
    BEST ANSWER: Thank you for your interest in this commercial amplifier. The matrix amp does have RS232 control. Please refer to the downloadable User's Manual for all necessary codes. You can also use one of our in-wall volume controllers when used in 8Ω mode.

    BGM 4.1 Indoor Outdoor 6.5-Inch sub with 4 x 2.5-Inch Satellites, 70V and 8-ohm incl Mounting Hardware (No Logo)
    BEST ANSWER: Thank you for your interest in our commercial audio products. The 4x120 amp is advised to run 70V load to 96W max per output channel (x4). The BGM system has 60W and 30W taps with 70V operation. You can safely run 1 @ 60W and 1 @ 30W per output channel for a total of 8 BGM systems. You can run all BGM @ 30W and power 12 total systems.
    Can this simultaneously playback 4 different mp3 files, one per zone?
    Luke L on Aug 30, 2017
    BEST ANSWER: Thank you for your interest in this commercial audio amp. No, the internal mp3 player can only play one file at a time.
    Do Need to use the satellite speakers? Can I just use the sub with my 70v system? Can I use 4 of these subs with your 4x120w mixer/amp and also use the 6.5" 70v speakers? will all these components work together?

    BEST ANSWER: You do not need to use the satellites. You can use with additional 6.5" speakers. Just run them all parallel. do not use the sub outputs as they are only 8Ω outs.
