PANEL:

MAIN SOCKET

please, make sure that the mains voltage of the amplifier matches the local mains supply.

An appropriate mains cord is included.

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.

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.

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.

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.
