DPX-1 Accessory Power Supply

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 con- nection 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.

Connection to an improper voltage source can cause immediate damage to the DSP-4!

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”.

To connect the DPX-1 to the DSP-4 module, plug the DPX-1 power con- necter 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.

QSC offers the DPX-1 accessory exter- nal power supply for applications with non-QSC amplifiers or with QSC Power- light models that do not provide the required operating voltage.
