EFX-LE Audio Controller Owner's Manual 3
1. Introduction
Thank you for purchasing the Musicom Lab EFX-LE Audio Controller.
The EFX-LE Audio Controller is the ultimate floor-based switching system.
It is a compact, easy to use, has 7 fully programmable loops, 2 function switches and a MIDI foot controller.
The EFX-LE Audio Controller has 360 memory locations, configured as 72 banks of 5 presets, plus a global preset. It
can transmit 8 MIDI Program and Control Change and messages on 8 MIDI channels and 18 MIDI Control Change
messages on an appointed MIDI channel.
Also one continuous controller port(XPDL) is included and can be programmed with a designated MIDI channel and
controller number.
The EFX-LE Audio Controller has two outputs, OUT L and OUT R, can be used as stereo outputs, or as an A/B/Y
switch for a mono guitar signal.
The EFX-LE Audio Controller has two low-noise, high quality buffers to prevent the loss of guitar signal. Each buffer
can be bypassed/engaged per each preset.
1.1 Main Features
• 7 audio loops. 4 mono loops, 2 stereo loops and 1 volume loop.
Volume Loop can be engaged/bypassed by IA switch or as parts of a preset.
• 2 stereo loops are stereo capable using TRS jacks.
• Changeable loop order per each preset.
• 2 buffers. Input buffer and Movable buffer.
Movable buffer can be placed anywhere in your signal path.
Each buffer can be enabled/disabled by IA switch or as parts of a preset.
• 2 internal unity mixers. each mixer has 2 input(2 Effects or 1 Effect + Dry signal).
Mixers also are used for spillover between presets, even with your analog delay or reverb.
• 2 function switches via one TRS jack. You can control the switching functions of your amp.
• 360 presets (72 banks x 5 presets) and 1 global preset.
• Create up to 99 songs
• Organize the 99 Songs into 40 sets of 40 songs
• Click-Less(Mute) function for reducing popping noise
• ISO OUT that prevent to occur ground hum noise and phase issue.
• Transmits 8 MIDI Program Change and 8 MIDI Control Change messages.
Each MIDI message can be stored differently in each preset.
• Transmits 18 MIDI Control Change message by assigned IA switches.
• Transmits MIDI Timing Clock and synchronizes with Function Switch1.
Tap tempo for both MIDI-compatible pedals and any pedals that have external tap input jacks.
BPM can be stored in each bank preset and song preset.
• Easily copy presets, banks, songs and sets
• 2 Lines x 16 Characters LCD display that can display preset/song titles and other status.

1 through 4 switches
When in Preset mode these switches are used to recall the corresponding preset. When in IA1, IA2 or IA3 mode
pressing these switch turn on/off the corresponding effect loop, function switches, ouputs and buffers.
5/TAP switch
This Switch can have two functions based upon your needs. By default, this button is set up to access
the Preset 5, You can also program this switch to TAP TEMPO. Refer to the Activate/Deactivate TAP Switch on the
page 9 of the manual.
MODE switch
Pressing this switch puts the EFX-LE into the IA1 mode, where you can turn individual loops on and off, and store
their settings to presets. For the other side, pressing this switch for 2 seconds puts the EFX-LE into the SETUP mode.
BANK▲switch
The 360 presets in the EFX-LE are arranged in banks of 5, and these buttons allow you to select which bank of 5
you’d like to access. Pressing this switch in Preset mode increments the bank number.
MUTE/BANK▼switch
This Switch can have two functions(MUTE and BANK DOWN).
Pressing and holding this switch in Preset mode decrements the bank number.
For the other side, pressing this switch will execute the MUTE function.

1.5 Rear Panel
IN Jack
This is the main input jack where your guitar plugs in.
SND 1-4, RTN 1-4 Jacks
These jacks provide mono-send mono-return effect loops. SND 1 – 4send signals to effect pedals. RTN 1 – 4receive
signals from effect pedals. Connect the SND 1
– 4jacks to the INPUT jack of each effect pedal, and connect the
OUTPUT jack of each effect pedal to the RTN 1 – 4jacks.
SND 5, RTN 5S Jacks
These jacks provide a mono-send stereo-return effect loop. RTN 5S jack is stereo capable using TRS connectors. If the
last stage of the chain is the stereo-send effect loop or the output, the signal is output in stereo. If the last effect loop
in the chain is the mono-send effect loop, only the signal received at the tip conductor of the RTN 5S jack is output.
SND 6S, RTN 6S Jacks
These jacks provide a stereo-send stereo-return effect loop. These jacks are stereo capable using TRS connectors. If the
last stage of the chain is the stereo-send effect loop or the output, the signal is output in stereo. If the last effect loop
in the chain is the mono-send effect loop, only the signal received at the tip conductor of the RTN 6S jack is output.
SND VL, RTN VL Jacks
These jacks are for connecting a volume pedal. You can also use these jacks as send/return for a preamp.
OUT L, OUT R Jacks
These are the output jacks. OUT-L and OUT-R can be turned on/off independently. If the last stage of the chain is the
mono output, the OUT-L signal is split up in to the OUT-R.
TUNER Jack
This jack is for connecting an external tuner.
F1/F2 Jack
Latch or momentary function switch jack for amplifier channel switching or on/off controlling of reverb.
TRS plug’s Tip : F1 TRS plug’s Ring : F2 TRS plug’s Sleeve : Common ground for F1/F2
XPDL Jack
An expression pedals can be connected to this jack using a 1/4” TRS cable. Also an external Tap-Tempo switch and
LED to this jack using a 1/4” TRS cable. The TRS cable must be connected before supplying power to the EFX MK-V.
Refer to the 5.1 XPDL on the page 33 of the manual for cabling.
ISO OUT Jack and ISO PHASE Switch
There is an isolation transformer before the ISO OUT jack. The isolation transformer may help reduce hum that can
occur when using two amps or 4CM. If the ISO OUT are used, ISO OUT can also be inverted the phase by pressing
the ISO OUT PHASE switch. Refer to the ISO-OUT SOURCE on the page 29 of the manual.
MIDI IN, MIDI OUT/THRU Connector
MIDI IN connector receives MIDI signals from an external MIDI device. MIDI OUT/THRU connector is used to feed
MIDI signals to external MIDI devices. When the operation mode of MIDI OUT/THRU has been set to 'THRU', MIDI
signals received at MIDI IN pass through the EFX-LE without any changes.
DC12V Power Connector
This is the main power input for the EFX-LE. The EFX-LE requires a DC12V supply. The current draw is
approximately 250mA at DC12V (Center Negative).

2.3 Mute
In the PRESET mode, pressing(& holding) MUTE/ ▼ switch will mute the guitar signal. When muted, the MUTE LED
turns on in purple. Pressing the MUTE/ ▼ or any switches from 1through 5switch will cancel the MUTE function.
NOTE
• The EFX-LE executes Bank Down or MUTE function, by Press & holding the MUTE/ ▼ switch for 1 second in the
Preset mode. Refer to the Hold “BANK DOWN” on the page 26.
• The mute function is not available in the IA mode.
• The mute position (VOL.LOOP, OUTPUT or NO ASSIGN) to be linked with this switch can be selected
in UTILITY menu. Refer to the Block Diagram on the page 4 and the Mute Position on the page 27 of
the manual.

the MODE and MUTE/ ▼ switches simultaneously.
TAP can be synchronized with MIDI Time Clock(MTC) or Function Switch 1(F1). The F1 supports for devices that
only have an analog tap tempo input. Also you can select whether to send the MTC/F1 for 1 bar, 2 bars or
continuously. When TAP switch function is selected, tapping the 5/TAP switch will change the MTC or F1 rate to the
tempo of your taps. At this time, the Global BPM will be changed to the tempo of your taps. When the EFX-LE
powers up, the Global BPM is 120.
Refer to the TAP SYNC WITH and TAP SYNC TIME on the page 28 of the manual.
3. Song / Set Mode
The Song operating mode allows access to the EFX-LE's 99 songs. A Song is a group of 5 presets that are selected for
use in a particular song. Each preset in a song can be chosen from any of the 360 presets. The Set operating mode
allows up to 40 songs of the EFX-LE's 99 songs to be arranged in any order to create a set. The EFX-LE can support
40 different sets.
When You are in the Song and Set mode, the MUTE/BANK ▼ or BANK ▲ Switches move from song to song instead of
moving from bank to bank.
Refer to the OPERATING MODE on the page 26 of the manual.
