Wharfedale Pro MP 2800S - Operating Mode Switches; Output Wiring

5
There are 3 different operating modes switchable for the MP series ampliers.
PARALLEL (right) mode- This setting connects both inputs together.
One signal feeds both channels. Each channel's Gain control and
loudspeaker connection remain independent.
STEREO (middle) mode- Each channel remains independent. The
amplier may be used for two different signals.
BRIDGE (left) mode- This setting combines both channels into a
single channel with twice the output power. Use only the rst channel's
input and Gain control. Set the second channel's Gain control at
maximum. The load must be rated for the higher output power.
OPERATING MODE SWITCHES
The MP Series employ Speakon output connectors. Ensure that only heavy gauge two conductor speaker cables with
professionally wired Speakon connectors are used for connection from amplier to loudspeaker.
STEREO and PARALLEL Mode- Connect each loudspeaker to its own channel of the amplier, as shown on the right
side of the Speakon. The Mode switches must be set for Stereo or Parallel Mode.
BRIDGE Mode- Bridge Mode congures the channel pair to drive a single audio circuit. The Mode switches must be set
for Bridge Mode. Connect the load as shown on the right side of CH A’s Speakon.
