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 donít 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, Ö, 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.

<lfe mix>

A signed byte value representing the LFE mix level.Valid range is 0 to -20, plus value 128=LFE Muting.

<position>

The speaker position.0=Front, 1=Center, 2=Rear.

<rear height>

The height of the rear speakers.0=Low, 1=High.

<rear position>

The position of the rear speakers.0=side, 1=middle, 2=behind, 3=high.

<reverb time>

The reverb time.Valid range is 0 (short) to 16 (long).

<sf preset>

The sound field preset.Valid range is 0 to 4 for presets 1 to 5.Subtract 1 from the preset number to get the parameter.

<sound field>

The sound field.The numbers that equal the various sound field names vary between models.

<speaker sizes>

A bitmap representing the speaker sizes.Hereís what the bits mean:

0x01 Front speaker size: large=0, small=1

0x02 insignificant

0x04 Downgrade center from large to small if front is large

0x08 Center speaker present? 0=yes, 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

<units>

The units to measure in when determining speaker distance.0=meters, 1=feet.

<wall type>

A signed byte value representing the wall type.Valid range is -8 (soft) to +8 (hard).
