input adopt MIC (1 ~ 4) the size of a balanced microphone input volume by the panel MIC (1 ~ 4) / MASTER
adjustment control knob and, in conjunction with BASS / TREBLE adjust the volume knob to achieve the
desired effect of hearing. MIC (1 ~ 3) microphone input, may also have recourse to TRS jack input. When
the microphone MIC 1 input signal, the highest priority to check the other input signal jack. At the same
time, MIC (1 ~ 4) can adjust the microphone gain. MIC input gain can be controlled in +10 ~ +44 dB. by
adjusting the size,

Note:
1. Before input the microphone, the volume must be transferred to the minimum to avoid sound
exposure.
2. When input Microphone, TRS connector / XLR connector can only select a permanent input;
otherwise, sound quality will be affected.
3. Ensure complete microphone input otherwise it does not work.

Note:
+48V phantom power to open, it must first be transferred to the minimum volume position,
to avoid sending the sound exposure.
