FUNCTION: The Function button is used to call up additional features from
the front panel. There are three standard features available through the Function
button:
ZONE LOCK: to lock the front panel so that it controls only a single Zone,
push Function, 1, then a number button corresponding to the zone number. To
return to all-zone control, push Function, 1 again.
STORE PATTERN: up to 16 complete crosspoint and sound configurations
may be stored in non-volatile memory. To save the present crosspoint and sound
control settings into memory, push Function, then 2, then a number button 1-16.
(This will erase the pattern presently stored under that number.)
RECALL PATTERN: to recall a stored pattern of crosspoint and sound
settings, push Function, then 3, then a number button 1-16. If no pattern has been
stored under that number, all crosspoints will be OFF.
3.4.6 CONTROLLING THE SOUND
Volume, tone, and balance (VTB) can be controlled via the RS232 control
inputs. All VTB commands are preceded by a $; xx=an output number from 01-16
(or for trim, an input number from 01-16)
To control volume send a command of the form: $vxx+, $vxx-, or $vxxyy where
xx is an output number and yy is a number from 00-63; 04 is the default value for a
1:1 ratio of audio in to audio out.
To control bass send a command of the form: $bxx+, $bxx-, or $bxxyy, as
above, but yy ranges from -7 to +7 (cut or boost); 0 is the default (neutral) value.
To control treble send a command of the form: $txx+, $txx-, or $txxyy, but yy
ranges from -7 to +7, as above; 0 is the default (neutral) value.
To control balance between the left and right channels send a command of the
form: $Sxx+, $Sxx-, or $Sxx0, where 0 resets balance to equal (+ decreases left
channel; - decreases right) The range of the balance is from -32 to +32; 0 is the
default value.
To mute the sound output send a command of the form: $mxx1 is mute on,
$mxx0 is mute off (default is off).
To select loudness on or off: $Lxx1 is loudness on; $Lxx0 is loudness off
(default is off).
To make a fade from the current value to zero or from zero back to the preselected
full volume send a command of the form: $Fxxyy0 is fade down to 0; $Fxxyy1 is
fade up to previous volume (xx is output number, yy is time to fade from 01-99,
where 99 is the longest fade.
To trim inputs send a command of the form: $ixx+, $ixx-, or $ixx0, where 0 is no
trim; the range is from -3 to +3, default trim is 0.
