Sony Receiver commands (DSP:195; 115)

 

This is the equivalent of device 144 in that it covers the sound field and EQ functions of Sony receivers.  We have a lot more codes for this than anything else for the receiver.

<?> <?>

Selects sound field preset?  Parameters might be <bank> <channel> similar to the 193.81 tuner presets.

142

 

<sf preset>

Selects a sound field preset.

144

 

<position> <band> <freq H> <freq L> <gain> <slope> <eq type>

Sets speaker distance settings.

150

 

<rear position> [<rear height>]

Selects placement position of rear speakers.

<front xfreq> <center xfreq> <rear xfreq>

Sets the crossover frequency for speakers.

152

<band> <freq H> <freq L> <gain> <slope> <eq type>

Sets surround EQ settings.  These settings are surround mode specific.

153

<balance>

Sets the front balance.

154

<trim>

155

<trim>

Sets the surround trim.

156

<phase>

Sets the subwoofer phase.

160

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.

<center xfreq>

<front xfreq>

<rear xfreq>

Crossover frequencies for the appropriate speaker(s).  Valid range is from 40 to 200 in increments of 10.

<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 for most receivers, although some are based on percents and take from 0 to 150.

<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.

<phase>

0=normal, 1=reversed.

<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.

<slope>

0=narrow, 1=middle, 2=wide.  Usually 1.

<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.  Here’s 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

<trim>

Valid range is -10 (-5.0 dB) to 10 (+5.0 dB), with each increment being .5 dB.

<tt mode>

0=off, 16=auto, 32=left, 33=center, 34=right, 35=right surround, 36=left surround, 37=subwoofer.

<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).
