KHE ACS SERIES – USER MANUAL www.KHE-AudioElectronics.com 17 / 23
Connect S-LINE SEND from device #1 to S-LINE RETURN from device #2. Repeat this wiring scheme for any number
of switchers. Do not use instrument-type patch cables, as this line is carrying high power speaker signals.
6. Setup guitar input lines
Link the guitar inputs lines of the switchers together by a short instrument pactch cable (unbalanced, shielded) :
Connect TUNER-OUT from device #1 to GUITAR-INPUT (rear) of device # 2. Repeat this wiring scheme for any
number of switchers.
7. Power up all units
8. Check status of the CTRL-LED:
green: Network setup ok. System ready to use.
red & green: Network setup failed. Check MIDI channels and communicaiton lines.
red: Standalone mode. No switchers in network detected.
Notes
 Always plug your guitar into ACS#1.
 MIDI control by CC or PC messages works perfectly in Link Mode. You can save and recall presets
across multiple switchers.
 When Link Mode is enabled, the Recall Mode will be disabled.
 Use high-quality 5-pin MIDI cable for connecting the devices together. All 5 pins are needed !
 All linked switchers must be powerd on to activate the switching operation.
 When adding new switchers to your setup, perform a system reset prior setting up the Link Mode (to
clear any stored MIDI PC presets, to avoid possible collision of preset configurations.
FAQ Link Mode
 Can i link different versions of the ACS-Series together (eg. ACS 4x4FX + ACS 8x4 + AFX8) ?
Yes, you can link any version together, EXCEPT for the ACS 4x2 (unfortunately no more space on the
ACS 4x2 for the needed additional jacks and circuitry)
 Can i link multiple fx-loop switchers such as ACS 4x4 FX and ASX ?
Yes ! For linking multiple ACS 4x4 FX, use two y-splitter cables to connect the fx-loop lines.
 When using Link Mode, can i still use a MIDI controller to control all the switchers?
Yes, you can use a MIDI controller to control any number of switchers. Simply connect your MIDI
controller in one of the MIDI inputs. The switcher takes care of exchanging the received Midi
commands with all other switchers in the network. Please refere to XXX to learn more on how to use
and address all MIDI functions in network operation.
 Is MIDI the used communication protocol between the switchers?
No. Standard MIDI protocol is uni-directional only. In order to exchange status and commands, the
communication needs to be bi-directional, so the switchers can properly talk together (call &
response). The ACS uses a robust, industry-standard CAN communication protocoll.
 But why the MIDI connectors?
MIDI connectors are used because they already exist in most studios wall connector boxes. This way,
you can easily setup multi-room setups, connecting the switchers by already existing connections
between the rooms (for example, ASX in the control room, CSX in the recording room).
 Can i damage something if i accidentally mix-up MIDI connectors and control connectors?
No, all jacks are protected for this scenario, nothing bad will happen to the switcher or the MIDI
device.
 Can i user the Attenuator Insert in Link Mode?
When linking multiple ACS together, the Attenuator Insert feature will be limited, as the S-LINE jacks
will used for the linking of the speaker lines. If you want to use the Attenuator Insert in Link Mode,
shoot us a message to discuss setup possibilities.
