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
✔ run pedals like boosts, overdrives, distortion and fuzzes in front of all amps
✔ 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 ACS 8x4
Amp and Cab Switching – instantly switch between 8 amps and 4 cabs. No need to put your tube amps into standby or stop playing!
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).
Dual-Cab Mode - activate and play two speaker cabinets or load boxes in parallel at the same time
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!

ACS 8x4 - Basic Setup
ACS 8x4 with FX-Loop Switching
The ZMX-1 is an automatic impedance matching device for the KHE ACS amp/cab switchers. It automatically corrects any impedance mismatch between the amps and cabs on the ACS system (speaker-level).
The ZMX uses a custom 150W auto-transformer for the impedance matching (single-phase multi-tap transformer, made in USA, switched by relays)
The ZMX is programmed with the impedance value for each amp / cab on the ACS switcher. If not matched, the ZMX automatically matches and corrects the impedance.
Handles any 16Ω / 8Ω / 4Ω / 2Ω device and also automatically handles uneven values like 5.3Ω, 3.2Ω, 2.6Ω in Dual-Cab Mode (special transformer taps)
Connects to the ACS Attenuator Loop, so it sits between the amps and cabs. Attenuators can be used too (the ZMX can match one side)
The ZMX is connected to the ACS CTRL IN port for phantom power and network communication
Manual Bypass, Auto-Match-Bypass and Transistor-Amp-Bypass modes
A single ZMX can be used with multiple ACS switchers in a linked setup
Safe & automatic impedance switching. Never worry about the impedance again!
No change in tone or dynamics, the ZMX is as transparent as it gets (passive signal path)
Compatible with any tube amp, solid-state / class-d amps, speaker cabinets, load boxes and attenuators (all mono)
The ZMX is designed specifically for the KHE ACS and does not work with other amp switchers or without an ACS.
Size: 24cm x 19cm x 9cm, including 2u rack mounting brackets
Including 1m red DIN-5 cable for power and network (ACS CTRL IN)
No power adapter required, it gets phantom-powered by the ACS
Compatible with all KHE ACS switches that have he CTRL IN port
30 day money-back guarantee
5 year warranty
Built in Switzerland

Note: If you use the ZMX in a linked ACS Setup, let me know the switcher models in the comment section during checkout. Maybe it requires an additional connection box, which I’ll add for free.
