(1) Microphone output is not muted during muting (ABC = 000 or 100).
(2) For the gain and relative phase, see block diagram.
1) L / R input and output in the through mode are synchronous with a gain of 14dB.
2) L / R input and TK output in the key controller mode are synchronous with a gain of 8dB.
3) L / R output and FK input in the key controller mode are synchronous with a gain of 6dB.
4) MIC input and L / R output are negative phase with a gain of 8dB.
