Input 4 (SRND) can be set to a special operating mode (surround mode) for use
with surround decoders.
In this mode of operation the PA 3100 HV assumes the role of amplifier for the
front channels of the surround system.
In surround mode the volume control for input 4 (SRND) is managed indepen-
dently of the volume for the other sources.
This makes it possible to select a volume setting for the PA 3100 HV in sur-
round mode which is optimum for the front channels of your surround system.
Once set up, the machine returns to this precise volume level every time you
switch to the surround input of the PA 3100 HV. In addition to the volume
setting the values for balance, flat, loudness and the speaker outputs are
managed separately too.
If the Surround function is selected for one of the inputs named above, "SR" is
shown on the screen instead of the currently set volume value.

A wiring diagram for the amplifier in conjunction with an external surround
decoder is included in "Appendix A".
To avoid altering the volume accidentally, the value for volume can only be
adjusted after pressing the Volume knob.
When the correct value is set, press the Volume knob again to confirm the
setting.
Surround mode is switched on and off in the Configuration menu at the
'Sources' item. To switch the function on, select the "SRND" operating mode at
the "IN4 function" item (see chapter entitled "Basic settings of the
PA 3100 HV").
The PA 3100 HV includes the facility to be switched on remotely using a trigger
signal (switching voltage, +5 ... +20V). Many external surround decoders are
designed to deliver the trigger output this requires. The facility can be used to
switch the PA 3100 HV on in parallel with the decoder, and at the same time to
select the appropriate source and the correct volume level (IN 4(SRND)).
The Trigger function is set in the Configuration menu. If you wish to use this
function in surround mode, set the Trigger function to "IN 4/SRND" (see
chapter entitled "Basic settings of the PA 3100 HV").

Recording with the PA 3100 HV

If you wish to make a recording using a recording device connected to the
PA 3100 HV, select the appropriate recording source on the PA 3100 HV by
turning the source select knob, or pressing the corresponding Source button on
the remote control handset. The signals from this source are then available at
the Recorder Out sockets.
If your recording device features a Tape Monitor function, the recording can be
checked using the Monitor function. The Monitor function can be switched on
and off by holding the SOURCE knob pressed in or in the Audio menu (please
refer to the chapter entitled "Basic functions of the PA 3100 HV / Audio
menu").
