DAISY-CHAINING THE DSP-3 OUTPUTS TO ADDITIONAL AMPLIFIERS
The DSP-3 provides audio output jacks for each channel. These outputs may be used for daisy-chaining the post-DSP signal to other
amplifiers or for monitoring purposes. The signal on the output jacks is post-DSP. All signal processing functions done by the DSP-3 effect
the signal provided to the output connectors as well. The terminal block outputs are active even when the DataPort connections are used.
To daisy-chain the DSP output, connect the output jacks of the DSP-3 to the input jacks of the next amplifier.
Make sure that
all interconnecting cables are balanced and connected properly.
CONNECTION TO ACCESSORY EXTERNAL DC
POWER SOURCE
When the DSP-3 is used with QSC Powerlight amplifiers
that do not provide the required +15VDC through their
DataPort connection OR is used with non-DataPort ampli-
fiers, power must be supplied to the DSP-3 from an external
power supply.
QSC offers an accessory external power supply for applica-
tions where a DataPort that provides +15 VDC is not
available. Contact QSC’s Technical Services Department
for details. Although
not recommended
, third-party ex-
ternal power supplies may work with the DSP-3 provided
they are of the correct voltage, voltage type (DC) , current
rating and polarity. Any damage to the DSP-3 caused by
connection to a non-QSC external power supply is not
covered under the warranty.
Ensure that any external power supply connected to
the DSP-3 is of the proper voltage type, level and
current rating.
Be certain that the connector polarity is correct as
there is no industry standard!
Connection to an improper voltage source can cause
immediate damage to the DSP-3!
Insert the coaxial power plug into the EXTERNAL
POWER jack. Ensure that the plug is firmly seated in
the jack. Use the “tab” provided on the chassis for
securing the power cord with a tie-wrap (wire-tie).
QSC offers an accessory external power supply for applica-
tions with non-QSC amplifiers or with QSC Powerlight models
that do not provide the required operating voltage.
