EXPLANATION OF THE FUNCTIONS.
(Note : (h) means hexadecimal data, (b) means binary data)
l Bass level (Sub address 00 (h))
Bass level control. Cross-over frequency is 1 kHz.
Effective control data range is 0E (h) ~72 (h) (100steps). Set this data to 0E (h), bass level goes to minimum
level, and set this data to 72 (h), bass level goes to maximum level. Set this data to 40 (h), bass level goes to
center level.
Switch on default data is 40 (h).
Control range is ±12 dB (typ.).
l Treble level (Sub address 01 (h))
Treble level control. Cross-over frequency is 1 kHz.
Effective control data range is 0E (h) ~72 (h) (100steps). Set this data to 0E (h), treble level goes to minimum
level, and set this data to 72 (h), treble level goes to maximum level. Set this data to 40 (h), treble level goes
to center level.
Switch on default data is 40 (h).
Control range is ±12 dB (typ.).
l Volume control (Sub address 02 (h))
Volume control of L-ch, R-ch, and W-ch outputs.
Effective control data range is 00 (h) ~72 (h)
Switch on default data is 00 (h).
l Woofer level control (Sub address 04 (h))
Volume control of only W-ch output.
Effective control data range is 00 (h) ~72 (h)
Switch on default data is 00 (h).
l Balance control (Sub address 05 (h))
Balance control. Set this data to 40 (h), balance goes to center.
Effective control data range is 00 (h) ~7F (h).
Switch on default data is 40 (h).
l Input matrix control (Sub address 03 (h) / b1~b0)
Output signal selection control.
Set these bits to 00 (b), output mode goes to normal mode (input signal of terminal 6 is outputted to terminal
16, and input signal of terminal 8 is outputted to terminal 13). Set these bits to 01 (b) output mode goes to
R-ch mode (input signal of terminal 8 is outputted to terminal 13 and terminal 16). Set these bits to 10 (b)
output mode goes to L-ch mode (input signal of terminal 6 is outputted to terminal 13 and terminal 16). Set
these bits to 11 (b), output mode goes to reverce mode (input signal of terminal 6 is outputted to terminal 13,
and input signal of terminal 8 is outputted to terminal 16).
Switch on default data is 00 (b).
