Rear Panel


1. AC Line-in - Firmly plug the supplied AC power cable into the socket
2. Fuse - replace with only the same fuse as indicated for your country
3. 120V/220V Power Selection Switch - Select 120V for use in the USA and
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.
