Parameters
|
Parameter Name |
Description and Format |
|
<balance> |
A signed byte value
representing the balance. Negative
values are left and positive values are right. Valid range is -8 (far left) to +8 (far
right). |
|
<band> |
The EQ band. 0=Bass, 1=Mid, 2=Treble. |
|
<center dist> <front dist> <rear dist> |
The distance of the
appropriate speaker. Add 7 to the
distance to get the parameter, so the valid range is 7 (0 feet) to 47 (40
feet). I don’t know what the values
are if the <units> parameter is set to meters. |
|
<changed> |
16=not changed,
17=changed. |
|
<compression> |
The compression
level. 0=off, 1=0.1,
…, 9=0.9, 10=Standard, 255=Maximum. |
|
<effect size> |
The surround
effect size. Valid range is 0 to 20. |
|
<eq preset> |
The EQ
preset. 0=Off, valid range is 1 to 5. |
|
<eq type> |
The type of
setting you want to change. 0=Gain,
1=Frequency. |
|
<freq H/L> |
The frequency for
EQ settings. The H represents the
high-order byte and the L is the low-order byte. Numerous values have been observed. For bass: *100, 140, 220, *250, *315,
*1000. For mid: *500, 1000, *1200,
2500, 5000. For treble: *1000, 1400,
1800, 9000, *10000. The ones with
asterisks are the known frequency setting options, while the others are found
in gain settings (the value here may not matter). |
|
<gain> |
A signed byte
value representing the gain. Valid
range is -10 dB to +10 dB. Set to 0
for frequency settings. |
|
<level> |
A signed byte
value representing the EQ level in dB.
Valid range is -10 dB to +10 dB. |
|

1=no 0x10 Downgrade rear from large to small if front is large 0x20 Rear speakers present? 0=yes, 1=no 0x40 Subwoofer present? 0=yes, 1=no 0x80 insignificant |
