Explanation of the Functions. (note: (h) means hexadecimal data, (b) means binary data)
· Bass level control (sub address 00 (h))
Bass level control. Crossover frequency is 1 kHz.
Effective control data range is 0E (h) to 72 (h) (100 steps). 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 ±12dB (typ.).
· Treble level control (sub address 01 (h))
Treble level control. Crossover frequency is 1 kHz.
Effective control data range is 0E (h) to 72 (h) (100 steps). 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 ±12dB (typ.).
· Volume control (sub address 02 (h))
Volume control of only Lch and Rch output.
Effective control data range is 00 (h) to 72 (h).
Switch on default data is 00 (h).
· Woofer level control (sub address 04 (h))
Volume control of only Wch output.
Effective control data range is 00 (h) to 72 (h).
Switch on default data is 00 (h).
· 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) to 7F (h).
Switch on default data is 40 (h).
· Surround effect level control (sub address 06 (h)/b2 to b0)
Surround effect level control.
Effective control data range is 1 (h) to 7 (h). Set this data to 0 (h), surround function is off. Recommend
setting surround 2 data to 1 (b) when surround effect level set to “0”.
Set mute on when surround effect level is changed.
Switch on default data is 0 (h).
· Input matrix switch (sub address 03 (h)/b1 to 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 Rch mode (input signal of terminal 8 is outputted to terminal 13 and terminal 16). Set these
bits to 10 (b) output mode goes to Lch mode (input signal of terminal 6 is outputted to terminal 13 and
terminal 16). Set these bits to 11 (b), output mode goes to reverse 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).
· Input attenuation (sub address 03 (h)/b2)
When this function is active, input signals are -5dB attenuated at input stage of Lch and Rch. Wch
signal isn’t attenuated.
So, Wch output signal level is up to 5dB from Lch and Rch outputs relatively.
Set the bit to 0 (b), attenuation is inactive, set the bit to 1 (b), attenuation is active.
Switch on default data is 0 (b).
