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.
