JBL SYNTHESIS SDP-45
Setup
- 41 -
To calibrate output levels during the MANUAL internal noise test:
Please see the sections regarding the Remote Control and the Front
Panel User Menu for detailed instruction on how to turn on the internal
noise test and adjust levels.
Turn on the noise test by pressing the TEST button once to turn
it on and a second time to go to MANUAL.
The first speaker to play the test tone will be the Front Left.
Adjust the level using the Volume Up/Down until you reach the
desired SPL reading on your meter. For reference level we
recommend using 75dB when the meter is set to SLOW and C-
weighting. Once the Front Left speaker is set you will now be
able to move on the next speaker.
Press the TEST button again to move to the next speaker.
Adjust the next speaker to the same SPL reading.
After each speaker is adjusted press TEST to move to the next.
When all speakers have been set the unit will exit the TEST and
return to normal operation.
To calibrate output levels during the AUTO-CYCLE internal noise
test:
Turn on the noise test by pressing the TEST button once to turn
it on to AUTO-CYCLE
The first speaker to play the test tone will be the Front Left.
Adjust the level using the Volume Up/Down until you reach the
desired SPL reading on your meter. For reference level we
recommend using 75dB when the meter is set to SLOW and C-
weighting. The test will automatically move after a few seconds
to the next speaker.
Adjust the next speaker to the same SPL reading.
Each speaker will be tested in sequence, moving after 4 seconds
on each speaker.
When all speakers have been set the unit will exit the TEST and
return to normal operation.
CROSSOVER
If you are using the SDP-45 with a JBL Synthesis System
including the JBL Synthesis SDEC Digital EQ / Speaker Processor then
you should always leave the crossovers set to 80hz (default) for all
speakers unless directed by Technical Support to do otherwise.
Crossover points can be selected in 5Hz increments within a 40 to
200Hz range.
