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

OPERATING MODE SWITCHES

There are 3 different operating modes switchable for the MP series amplifiers.
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
amplifier 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 first 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.

OUTPUT WIRING

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 amplifier to loudspeaker.
STEREO and PARALLEL Mode- Connect each loudspeaker to its own channel of the amplifier, as shown on the right
side of the Speakon. The Mode switches must be set for Stereo or Parallel Mode.
BRIDGE Mode- Bridge Mode configures 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.
WARNING: Do not use less than 4 ohm load in Bridge Mode!
WARNING: Note polarity of connection for Bridge Mode.
OUTPUT WIRING WARNING: CLASS 2 WIRING SHALL BE USED. FOR BRIDGE MODE, CLASS 3 WIRING SHALL
OUTPUT SAFETY WARNING! Make all connections with amplifier turned off. Risk of hazardous energy!
