Head room adjuster
The head room adjustment level is switched by switches (Q400 to Q414), and an input level is selected by [Reference
Level] of the menu (-12dB, -16dB, -18dB, or -20dB).
A/D, D/A converter circuit
A 24-bit AK-4621 (IC600, IC601) that has an A/D converter and a D/A converter is used.
The sampling frequency is set to 48 KHz. A differential amplifier is mounted before analog input and after analog output.
IC600 performs A/D conversion for two channels, and IC601 performs D/A conversion for two channels.
Final-stage amplifier
Audio signals are sent from the final-stage amplifier (IC421, IC422) through the MB-1210 board to the 5-pin XLR
connector (CN103) on the AXM-52 board.
Monitor amplifier
The monitor amplifier consists of a monaural SP /stereo HP amplifier (IC604), a headphone jack (CN2) on the HP-171
board, and a monaural speaker connected to the FP-208 board.
Selection of HP or SP is made by the monaural SP/stereo HP amplifier (IC604), which is controlled by IC0100 on the
DPR-362 board with the I²C interface.

Operation
Initial operation
When the FPGA (IC801) is activated and the FPGA configuration is completed, IC0100 on the DPR-362 board boots
the DSP (IC1000) and writes necessary coefficients. Then the DSP (IC1000) starts processing.
Audio signal flow
The front MIC input signal is sent through the MB-1210 board to the analog switch (IC401 to IC404) of the input signal
selector.
The rear external LINE/MIC input signal is sent from the AXM-52 board through the MB-1210 board to the analog
switch (IC401 to IC404) of the input signal selector.
Analog wireless signals are sent from the RX-136 board through the MB-1210 board to the analog switch (IC400 to
IC404) of the input signal selector.
