Precis HT Instruction Manual

Adjusting Audio

Precis HT models feature output volume control and digital input gain adjustment for the audio analog
signals. Audio adjustments can be made using either the control panel or BCS commands sent through a
serial controller. (For information on audio adjustment using BCS commands, see the

BCS Protocol

Instruction Manual

.)

Note

:

The status of the analog audio signals can be checked only from an external serial controller

via BCS commands.

When audio is adjusted for a device on one level containing audio, the adjustment remains in effect for that
device on all levels switching that same type of audio signals.

Important:

For AMX AutoPatch systems, the total through-system gain (the amount of input gain

plus the amount of output gain) specified for any input/output routing path cannot exceed 10 dBr.
If you enter a volume (gain) command that exceeds 10 dBr when it is combined with the gain of
an input, the command will be accepted (and will be indicated in status results) but will not result
in an audible difference of more than 10 dBr.

Adjusting Output Volume

Volume control adjustments (within the volume range for the specific analog audio outputs) can be made at
any time during normal operation.

The Control Panel must be in Switch mode to make audio adjustments (to return to Switch mode at any
time, press the Cancel Key). Follow the steps below to adjust the output volume. Each press of an arrow key
increases or decreases output volume by 1 dB if the volume is below -30 dBu, and by 0.5 dB if the volume
is above -30 dBu.

To adjust output volume:

1.

Press the Cancel Key to put the panel into Switch mode.
All the control panel lights turn off.

2.

Press and hold the Volume Adjust Key for at least 2 seconds.
The Volume Adjust Key illuminates and then flashes.
The control panel is in Volume Adjust mode.

3.

Press an Output Key to select the output that needs volume adjustment.
The selected Output Key illuminates, along with the Up Arrow (Macro) and Down Arrow (Lock) Keys.

4.

Press and release the Up Arrow Key to increase the volume.

Or

Press and release the Down Arrow Key to decrease the volume.
The pressed key flashes and then stays illuminated.

5.

Repeat Step 4 until the desired volume level is reached.

6.

Press the Cancel Key to return to the Switch mode.

Note:

Pressing the Cancel Key does not cancel the volume adjustments that were just entered

.
