It's like a Weber Z-Matcher but it's rack mountable and remotely controllable when synced up with other KHE ACS units. It allows you to use basically any combo of amp / cab impedance and compensate for any impedance mismatches. Very useful looking unit.
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).

ZMX-1 - Automatic Impedance Matcher
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
