MULTISELECTOR 4X
BIDIRECTIONAL SWITCHER
Model MLTSEL4X
Four momentary switches on the front panel select between channels, with the active channel identified by a red LED. Activating a channel
disconnects the previous selection. A separate, green LED indicates connection of the optional foot controller, the MultiSelector
MLTSELPRO4XR Remote.
The rear panel contains unbalanced ¼” jacks for signal input and output, a
9VDC power jack (center negative) for connecting the included 9VDC linear
power supply (PS9-MSEL) and a female XLR connector for connecting the
optional remote footswitch.
The optional MultiSelector MLTSELPRO4XR
Remote “stomp box” style footswitch contains
four switches that remotely control the switching
functions of the rack mount unit using a regular 3-
pin XLR microphone cable. A unique, proprietary
communication protocol ensures reliable
switching with mic cables up to 100 feet long.

The MultiSelector 4X (MLTSEL4X) is the newest revision of the classic Whirlwind MultiSelector bidirectional instrument/amplifier switcher. The
MultiSelector 4X provides totally noiseless switching between channels using computer-grade digital logic to control optical switches.
This single rack space unit features versatile 1-in to 4-out or 4-in to 1-out routing to perform almost any signal-switching task in an instrument or
keyboard rig. Only one input to output connection is active at a time.
Use it to select between one of four instruments into one amp or use it the other way around to send one instrument to any one of four audio inputs.
Whichever way you use it, the MultiSelector 4X is the quietest channel-switching device available.
ŸBidirectional - 1 input to 4 outputs or 4 inputs to 1 output
ŸTotally silent optical switching
ŸUses optional MultiSelector MLTSELPRO4XR Remote footswitch
ŸSelecting a channel on the rack or remote turns off previous selection
ŸRemote footswitch connects with ordinary XLR mic cable
