KHE Audio | CSX 8

8x Switching System for Guitar Speaker Cabinets and Load Boxes
with MIDI control

>>> USER MANUAL <<< (pdf)

The KHE CSX 8 can be used as a standalone 8x guitar cab or load switcher with 1 amplifier input

Alternatively, it can be used to expand other KHE ACS rack switchers with 8 additional cab channels.

The KHE ACS is the most advanced guitar amp switcher on the market:

✔ switch between any combination of guitar amps and cabs instantly, by the push of a button
✔ switch between speaker cabinets and load boxes for silent recording
✔ use a single power attenuator across all amps
✔ full MIDI control

✔ switch while you play - no need to put amps into standby or stop playing!
✔ works with tube & solid-state amps, speaker cabinets & load boxes, heads & combos
✔ 100% safe for tube amps: no amp can be activated without a load, amps are protected by a load resistor
✔ modular system, multiple switchers can be linked together to expand switching capabilities

FEATURES CSX 8

• Amp and Cab Switching – instantly switch between 1 amp and 8 cabs. No need to put your tube amps into standby or stop playing!

• Expand KHE Switchers - add an CSX 8 to other KHE ACS rack switchers and add 8 additional load channels

• Attenuator Insert – attenuate the volume of all amps by inserting a global power attenuator into the post-amplifier pre-speaker insert loop (like Waza TAE, OX Top Box, Two Notes etc).

• Midi Remote Control - manage your entire amp collection at your footstep by using MIDI footswitch to control the ACS

• Link Mode - multiple switchers can be linked together to expand switching capabilities. Mix and Match the different models, and grow your switching system with your needs! 4x2, 4x4, 8x4, 8x1, 8x8, 12x4, 16x4, 16x8 ... everything is possible!

WIRING DIAGRAM

The CSX 8 linked to an ASX for a 8x8 setup with global attenuator. The CSX can be linked to any other KHE rack switcher to expand the setup with 8 more cab switching channels.

TECHNOLOGY

Inside the ACS, a digitally controlled relay matrix switches between all amps and cabs. The switching procedure is timed and controlled by a microcontroller for fast, precise and reliable switching. A special mute circuit removes any clicks and pops during switching -the switching process is more silent than most amp’s channel switching! Advanced shielding techniques are used inside the ACS to shield the sensitive input lines from the powerful output lines.

COMPATIBILITY

The KHE ACS is compatible with all types of amplifiers and load devices, such as tube amps, solid-state amps, speaker cabinets, load boxes and power attenuators, up to 150 watts per channel. It works beautifully from sparkling clean sounds to ripping high-gain tones!

SAFETY FEATURES

Load Resistors - All amps are connected to a dummy load resistor to protect the power amps. All unused amps get muted at their inputs, so no signals can reach the power amp.

Load Detection - Cabinet jacks are supervised for a speaker cabinet or load box. If no load is connected, the cabinet outputs are automatically locked and excluded from the switching operation.
This ensures amplifiers can never be activated without a real load connected.

No Cab? No Amp! A clever digital switching logic makes sure no invalid combination is possible: If no load is activated, you can not enable an amplifier.
