• TRIM (10th byte)
This command is used to set the reference level [dBu] of the input terminals.
• Function ON/OFF (11th byte)
This command is used to turn ON/OFF the parametric equalizer (PEQ), feedback reducer (FR) and low-cut filter (LCF) with the 8-bit
data.
bit7 bit6 bit5 bit4 bit3 bit2 bit1 bit0
01000PEQFRLCF
When you want to turn ON PEQ, FR and LCF, set the corresponding bit to 1. When you want to turn them OFF, set the corresponding bit
to 0.
Bit-3 to bit-7 are fixed all the time.
• FR frequency (24, 27, 30, 33 and 36th bytes), FR gain (26, 29, 32, 35 and 38th bytes)
This command is used to set the center frequency and the gain of the notch filter used for the feedback reducer.
Method of setting is the same as the of the PEQ frequency and PEQ gain. See pages 33 and 34.
• Compressor (39th byte)
This command is used to set the compressor.
