Connection To Accessory External Dc Power Supply - QSC DSP-4 Hardware Manual

INSTALLATION-
Connection to accessory external power supply (DPX-1)
When the module is used with QSC amplifiers that do not provide +15 VDC through their DataPort connection
OR is used with non-DataPort amplifiers, power must be supplied to the DSP-4 from an external power supply.
All non-QSC amplifier applications require use of the DPX-1 accessory external supply. Contact QSC's
Technical Services Department or your QSC representative for more information. Any damage to the DSP-
4 caused by connection to a non-QSC external power supply is not covered under the warranty. Use of the
DPX-1 with QSC amplifiers that do provide +15VDC through the DataPort will not harm the DSP-4, although
it is not necessary.
QSC offers the DPX-1 accessory
external power supply for applica-
tions with non-QSC amplifiers or with
QSC Powerlight models that do not
provide the required operating
voltage.
To connect the DPX-1 to the DSP-4
module, plug the DPX-1 power
connecter into the DSP-4's External
Power jack. Then plug the DPX-1
into the AC outlet. After the DSP-4
module has been powered up, the
amplifier may be turned on.

DPX-1 Accessory Power Supply
When using the external power source, we recommend that the
DSP-4 be powered-up before the amplifier in order to insure trouble-
free start-up. This will avoid audio "thumps & bumps".
Connection to an improper voltage source can cause immediate
damage to the DSP-4!
