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

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!

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.

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).
