countries with 110V service. Select 220V for European use or countries with 220V.
Note, the fuse must be changed to match your electrical service.
4. Amp Out with “Speakon” connector – Connect your amplifier to the speaker cab-
inet using a Speakon cable. NEVER connect plus or minus to ground. Use Speakon-
to-Speakon for a better connection. If using a Speakon to 1⁄4” connection, turn
amplifier OFF before making connections. The PS 1000 has two Speakon
outputs. The PS 400 has one Speakon Output. Use minimum 4-ohm cabinets.
5. Bridging Switch (PS1000 only) – To access all 1000 watts of the PS 1000,
switch this button to Bridge Mode, and connect your cabinet to the indicated ‘A’
speaker input only. Your cabinet(s) must deliver a total minimum load of 8-ohms.
6. Pedal Control – Allows you to mute and engage the Mid-Cut features via the
optional foot switch. Uses a 1/4” TRS plug.
7. Effect Send – Use this jack to send a signal to your effects processing device.
8. Blend – This feature allows you to mix the dry signal with the effected signal.
When using a processor like a Graphic EQ or a Compressor/Limiter, turn the blend
all the way to right. This ensures that 100% of the signal will go to the processor.
When using Reverb, Delay or a Chorus/Flanger-type effect, rotate the knob to the
left to achieve the desired blend of effect to dry signal.
9. Return – Use this jack from your processor output.
10. Tuner Out – Connect a tuner via instrument cable and tune silently in mute mode.
11. Preamp Out – For bypassing the amp stage when using an alternate amplifier.
12. Pre/Post EQ – Selects direct output (DI) signal to come before or after EQ section.
13. Direct Out Level – Adjusts the signal coming from Direct Out. This is usually kept
at the twelve o'clock position. Adjust accordingly in conjunction with different
applications (recording, live, etc).
14. Direct Out (XLR) – Sends a balanced signal to the PA or a recording device.
15. Ground Lift – Disconnects chassis ground to reduce 60 cycle hum.
