CH A & B STEREO
3-way mode: (one channel bridge + 2 stereo)
the bridged channel uses 1+ as positive and 2+ as negative
for bridging Channel A+B set the switches 1, 2, 5, 6, 7, 8 to the left,
and switches 3, 4 to the right
for bridging Channel C+D set the switches 1, 2, 3, 4, 5, 6, to the left,
and switches 7, 8 to the right
Use balanced XLR male input connector
Wiring:
1) earth/ground/shield
2) hot
3) cold

BRIDGED MODE - 2 channel mode
When used in bridge mode P4700 uses channel A and channel C XLR input, Be sure to set the dip-switches correct,
(1, 2, 5, & 6 to the left, and 3, 4, 7 & 8 to the right) Use 1+ as positive (+) and 2+ as negative (-) in each speakon.
PARALLEL MODE - 2 Signal input / 4 channel output
When using the P4700 in parallel mode,
Input XLR connector A connects to SPEAKON output 1, with 1+/1- for channel A out, 2+/2- to channel B out.
Input XLR connector C connects to Speakon 2, with 1+/1- to channel C out, and 2+/2- to channel D out

SPEAKON 2 SPEAKON 1
STEREO MODE - 4 Signal input / 4 channel output
When using the P4700 in stereo mode each XLR input A, B, C, D corresponds to four seperate amplier channel outputs.
Output A is connected on Speakon connector 1, on 1+/1-, Output B is connected on speakon connector 1 on 2+/2-
Output C is connected on Speakon connector 2 on 1+/1-, Output D is connected on Speakon connector 2 on 2+/2-
SPEAKON 2 SPEAKON 1
3-WAY MODE - 2 channel stereo + 1 channel bridged
When used in 3-way mode P4700 can use two channels bridged (either A+B or C+D) delivering up to 1350W into 4
ohm (not to be used in 2 ohm load) and the other two channels can be used as a stereo with up to 2 x 750W into 2
ohm load.Perfect for a setup with mono subwoofer and two stereo top channels, where the bridged mono subwoofer
can utilize more power in a better and more e󰀩cient way.
For bridging A+B and keeping C and D as stereo, set dipswitches 1, 2, 5, 6, 7, 8 to the left and 3, 4 to the right
For bridging C+D and keeping A and B as stereo, set dipswitches 1, 2, 3, 4, 5, 6, to the left, and 7, 8 to the right
