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!
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.

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.
