Optimizing Signal-To-Noise - Bose PANARAY Installationsanleitung

Optimizing Signal-to-Noise using
®
the PANARAY System Digital
Controller with a Third-Party
Amplifier
In order to achieve the best signal-to-noise
performance with the PANARAY
controller, you must optimize the input sensitivity
and output range to match the equipment you are
interfacing with.
1. Before making any connections between the
PANARAY system digital controller and an
amplifier, make sure all of your electronics are
set to Off, and your amplifier level controls set
to Minimum.
2. Next, connect an audio source to the PANARAY
system digital controller inputs CH1 and CH2. If
you have a mono source, plug your connection
into CH1 and set the input configuration (locat-
ed under the utility button) to CH1 (mono).
3. Connect the PANARAY system digital con-
troller outputs to your amplifier inputs.
4. Turn on your audio source. Then turn on your
PANARAY system digital controller.
5. Select a Speaker EQ on the Panaray
controller by pressing the PRESET button and
use the Encoder wheel to select the desired
speaker EQ.
6. Set the PANARAY system digital controller's
input sensitivity. In general you should set this
parameter to match the output range of the
equipment you connect to the controller. A
digital product has the best signal-to-noise per-
formance when operating at 0dBFS (full scale),

so you should run the PANARAY system digital
controller as close to 0dBFS as possible.
For example: If you have a mixer with +4dBU
outputs, the PANARAY controller input sensitivity
should be set to +8dBu. This will allow you to
reach 0dBFS while at the same time providing
some additional headroom to account for peaks in
program material. Set the parameter based on the
amount of headroom needed.
To access the PANARAY system digital controller
input sensitivity, press the UTILITY button. Then
press the Arrow DOWN button until you see the fol-
lowing display:
Input Sense
20dBu
Adjust this parameter with the Encoder wheel to
match your audio source's maximum output.
Input Sense
8dBu
Next, send a signal from your audio source to the
PANARAY system digital controller and view the
front panel input meters to ensure your signal is at
approximately 0dbFS (full scale). Adjust the input
sensitivity parameter accordingly.
Note: The input signal may occasionally light the
red Overload LED. This is normal.
7. After you have properly calibrated your
PANARAY controller's input sensitivity, you
must adjust your controller's output range to
match your amplifier's input sensitivity. Since
this will vary with each manufacturer, please
consult your amplifier user guide.
