Sony RS-232C manual Trim 10th byte, PEQ frequency 12 and 15th byte, REF Level, Peq

•TRIM (10th byte)

This command is used to set the reference level of the input terminal.

REF LEVEL
-10dBu	30[H] (‘0’)
-9dBu	31[H] (‘1’)
-8dBu	32[H] (‘2’)
-7dBu	33[H] (‘3’)
-6dBu	34[H] (‘4’)
-5dBu	35[H] (‘5’)
-4dBu	36[H] (‘6’)
-3dBu	37[H] (‘7’)
-2dBu	38[H] (‘8’)
-1dBu	39[H] (‘9’)
0dBu	3A[H] (‘:’)

•Function ON/OFF (11th byte)

This command is used to turn ON/OFF the parametric equalizer with the 8-bit data.

bit7	bit6	bit5	bit4	bit3	bit2	bit1	bit0
0	1	0	0	0	PEQ	0	0

When you want to turn ON the function, set bit 2 to 1. When you want to turn OFF the function, set bit 2 to 0. Bit-0, bit-1 and bit-3 to bit-7 are fixed all the time.

•PEQ frequency (12 and 15th byte)

This command is used to set the center frequency [Hz] of parametric equalizer.
