2-11.CMG Adjustment (CH1, CH2, CH3, CH4) Condition Connect a resistor as follows. R1 24Ω Note 1 LMY4-MLF(each channel) R1 24Ω Note 1 Note 1)Limit the relative error of two 24 ohm resistors to a maximum 50 m ohm. q Adjusting VR100, VR200, VR300 and VR400 Set GAIN for 18 dB, apply a signal of +8 dBu/kHz to AMY4-MLF and adjust the pre-set volume (VR100 for CH1, VR200 for CH2, VR300 for CH3, VR400 for CH4) so that the output level can be as low as possible.
