The digital mixer amplifier shall be equipped with a minimum of four microphone inputs, alongside two AUX inputs and a singular recording output. It shall boast a speaker output compatible with both a constant voltage distribution system (100V) and low impedance settings (4 Ω). Designed to operate seamlessly on AC power, the mixer shall also feature a muting function for enhanced audio control. A dedicated knob shall be provided to adjust the volume levels of the MIC IN, AUX IN, and the master output efficiently.
Additionally, the mixer shall offer knobs designed to independently manage the boost and cut settings for high and low frequencies, allowing for precise sound shaping. A MIC Input with integrated phantom power shall cater to condenser microphones, while also accommodating a chime microphone via an RJ-45 Plug. This specific MIC input's volume shall be easily adjustable with a dedicated knob and shall be prioritized in the output hierarchy, ensuring that when activated, other inputs shall be reduced in volume. The extent of this attenuation can be customized from 0 dB up to 30 dB or below, according to user preference.
To safeguard the device's integrity, built-in current limiter circuitry shall protect the transistors, and thermal protection circuitry shall prevent overheating failures. All MIC inputs shall be designed as electronically balanced inputs for optimal sound quality.
The mixer shall feature several key indicators for operational status: a Power indicator to denote activation, a Protect indicator for the protect function, a Signal indicator for output presence, and a Peak indicator for peak level outputs.
For user convenience, a Power Switch shall be included to easily toggle the device ON and OFF. The mixer shall also feature a MP3-Panel, offering interfaces for USB, SD, Bluetooth, and FM functionalities. This panel shall include a LC-Display to show the status of USB, SD, Bluetooth, FM connections, and PLAY/PAUSE actions for the input signal. Additionally, knobs on the Panel shall allow users to control PLAY/PAUSE functions and volume settings.
The mixer shall provide an output terminal for high impedance speakers and include a recording output feature, which records the input signal prior to the master volume control, compatible with interfaces such as a cassette deck.
