The HPF / LPF / Fullrange Mode Switches allow your WX amplifier to drive a bi-amplified system without an additional
active crossover network. LPF is used to drive subwoofers, HPF to drive a Mid/Hi enclosure and Fullrange is used to
drive a Mid/Hi enclosure without a subwoofer.

The WX 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.

OUTPUT WIRING

1. Make sure that the power switch is set at the OFF position while making connections to and from the power amplifier.

2. Connect all devices in the signal path and ensure that each connection is secure.

3. Set all level and gain controls to their minimum. Connect the IEC power cord to the amplifiers IEC receptacle.
4. After powering up all other devices first, turn the power switch on the amplifier to the ‘ON’ position and verify that the

POWER LED is illuminated.

5. Turn the amplifier volume control up to the “7” setting. (This setting can be adjusted higher or lower, as needed,

after set-up). With source signal present start to set each gain stage in your signal path, starting at the beginning of
the chain. It is best practice to make overall volume changes with the master fader of your mixing console once the
amplifier input trim has been calibrated.

6. When powering down, make sure that the power amplifiers are switched off first.
