1 MAIN SOCKET
please, make sure that the mains voltage of the amplifier matches the local mains supply.
An appropriate mains cord is included.
2 INPUT
The XLR/TRS CoMBI-type connector inputs INpUT A, B, (C, D on Dp4950) are connect to mixing console
or other source. The XLR-type connectors LINK A, B, (NoT excisting on Dp4950) are prepared for through-
connecting input signals to additional external power amps. The input signal is directly routed to these output
connectors, even if power is switched off.
AUDIO CONNECTION CAbLES
Choosing high-quality balanced cables (two conductors for the audio + and - signal plus sepearate shielding
screen) with XLR-type connectors is recommended. Although connecting unbalanced cables to the power
amplifier inputs is possible as well, using balanced cables is always preferable. A great number of today´s audio
applications uses balanced outputs. With balanced cables, the shield connects all metal chassis parts and there-
fore efficiently eliminates the external interference -mostly noise and hum.
3 OUTPUTS
Speakon and Binding post -type loudspeaker connectors. The Speakon connector is designed specially for high-
power speaker connections. It locks in place, prevents shock hazard, and assures the correct polarity.
SPEAKER CABLING
Larger wire sizes and shorter lengths minimize both loss of power and degradation of damping factor. Do not place
speaker cables next to input wiring. please take care when binding posts are used, that there comes no possibility
to short cirquit from loosen cables.
4 SELECTING GROUND SWITCH
Ground lift means breaking a connection between chassis earth and electrical earth. Use this feature only
when 50Hz hum is excisting from loudspeakers.
5 SELECTING STEREO / bRIDGE MODE
STEREO MODE
Each channel within the pair remains independent, and each may be used for a different signal.
bRIDGE MODE
This setting combines both channels of a pair into a single channel with twice the output voltage. Use only the
input and gain control channel A. Set the channel B gain control at minimum.
