focus on your sound and creativity, instead of wasting your time with plugging cables and waiting for amps to warm-up.


Why an amp switcher?

Uninterrupted workflow & creative freedom

The ACS-Series features 7 versions, differing in size, features, and switching capabilities.
All switchers can be linked and daisy-chained together, creating the perfect switching-solution for any kind of setup.

  • Attenuator Insert - Use Power Attenuators like Boss Waza TAX, UA OX, THD Hotplate, ... across all amps, by inserting them into the post-amplifier / pre-speaker insert loop.
  • Dual-Cab Mode - activate and play two Speaker Cabinets or Loadboxes in parallel at the same time.
  • Midi Control - Manage your entire amp collection at your footstep by using MIDI Footboard to control the ACS. You can also use Desk Controllers, Midi Keyboards, or control the ACS by your DAW for maximum flexibility and convenience.
  • Link-Mode - For some hardcore amp freaks, a single ACS is not enough. The new Link Mode lets you combine and link unlimited ACS Systems together, creating massive amp setups, like 8x8 12x4 16x8 24x16 and many more. Mix and Match the different versions, and grow your switching system with your needs!

Safety Features

Switching tube amplifier is not that simple – bad and expensive things can happen if your amps sees no load. The KHE ACS is 100% safe for your precious tube amps:
  • Load Resistors - All unused amps are connected to a dummy load to protect the amps, simulating a speaker cabinet to protect your amps. All unused amps get muted at their inputs, so no signals can reach the power amp.
  • LoadDetection - each cabinet output jack is supervised for the presence of a physical speaker cabinet (or load box). If no real load is connected, the cabinet outputs are automatically locked and excluded from the switching process.This ensures amplifiers can NEVER be activated without a real load connected.

  • Compatible with tube and solid state amps, heads, combos, class-d amps, speaker cabinets and loadboxes, up to 150W per channel!
  • digital controlled relay matrix - all-pole make-before-break switching for reliable and safe operation
  • no hum or buzz - a programmable ground lift circuit eliminates 99% of all ground loop problems
  • Rear and front guitar input for easy reamping setups
  • Tuner output, which can also be used to key trigger inputs of Gate pedals, or to record a parallel DI-Track
  • digital control - no chance of activating a amp without load
  • silent switching - it's more silent than most of the amp's channel switching!

Switchers are in stock, ready to ship!

hi guys,

i wanted to show a quick rig-rundown of my current office rig here at KHE Audio to showcase some of the things you can do with my new amp cab switchers


At the heart of the setup is the new KHE ACS 4x4 amp cab switcher, which lets me select and play all amps and cabs instantly, even while playing.

Amps: A mesa dual rectifier, a laboga mr. hector and a engl blackmore all connected to the KHE amp switcher.

Speakers: a Harley Benton 2x12 cabinet with v30. both speakers are connected separately to the amp switcher, so i can use each speaker individually or both at the same time.

Attenuator: a Boss Waza tube amp expander is placed in the attenuator insert in the ACS 4x4, so i can crank all amps and control the overall volume of the rig by the boss tae and use the amps at bedroom level (the boss waza tae works beautifully at bedroom levels!)

Noise Gate: a Fortin Zuul placed in fx-loop of the waza to to kill any noise of the amps. the zuul is key'd from the clean dry signal of the guitar by tuner output of the KHE amp switcher. perfect tight gating!

i use a tubescreamer clone in front of all amps and a Boss ES-5 to control everything by MIDI so i can switch the amps and cabs by a footstep.


pretty rad setup! so much fun to play all the amps cranked with the different speaker combinations at low levels! The KHE ACS 4x4 combines and manages all the gear seamlessly - no more crawling behind the back of the amps and changing speaker cables, every amps is ready to go all the time

check out our new line-up of amp cab switchers and super-charge your amp collection :D
