The digital mixer amplifier shall be suited for broadcasting, paging, or background music. It shall have at least four microphone inputs, two AUX inputs, and one recording output. It shall provide speaker outputs for both a constant voltage distribution system (100 V) and low impedance operation (4 Ω). The unit shall operate on AC power and include a muting function. Dedicated controls shall be provided for adjusting the volume of the MIC IN, AUX IN, and master output.
The amplifier shall include independent tone controls for boosting and cutting both high and low frequencies. It shall provide five-zone selection outputs for high-impedance speaker systems. An All-Call control shall be provided to activate all zones simultaneously, while individual zone selector controls shall allow selection of specific zones.
A MIC input equipped with phantom power shall be provided for condenser microphones and shall also support a chime microphone via an RJ-45 plug. The volume of this MIC input shall be adjustable using a dedicated control. This MIC input shall have priority over other inputs, and when activated, the levels of other inputs shall be attenuated. The amount of attenuation shall be adjustable from 0 dB to 30 dB.
To ensure reliable operation, the amplifier shall incorporate current limiter circuitry to protect the output transistors and thermal protection circuitry to prevent damage due to overheating. All MIC inputs shall be electronically balanced.
The amplifier shall include the following indicators: Power (power on), Protect (protection circuit activated), Signal (output signal present), and Peak (output signal reaches peak level).
A power switch shall be provided for turning the unit on and off. The amplifier shall also feature an MP3 panel with USB, SD, Bluetooth, and FM interfaces. The MP3 panel shall include an LCD display indicating the status of USB, SD, Bluetooth, and FM functions, as well as PLAY/PAUSE operation of the input signal. Controls shall be provided for PLAY/PAUSE operation and volume adjustment.
The amplifier shall provide output terminals for high-impedance speakers. It shall also include a recording output that delivers the input signal prior to the master volume control, allowing connection to recording devices such as a cassette deck.
