EFX-LE II Audio Controller Owner's Manual 3
1. INTRODUCTION
Thank you for purchasing the Musicom Lab EFX-LE II Audio Controller.
The EFX-LE II 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 II Audio Controller has 640 memory locations, configured as 160 banks of 4 presets, plus a global preset.
It can transmit 12 MIDI messages (Program and Control Change and Note) when a preset is changed. Also, it can
transmit 4 MIDI messages when the switches assigned to the page are pressed.
One continuous controller port(XPDL) is included and can be programmed with a designated MIDI channel and controller
number.
The EFX-LE II Audio Controller's loops can be changed the order, connected in parallel. It has two mixers/volume-
contorllers, allowing you to store volume values for each preset.
The EFX-LE II 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 II 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 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 mixers/volume-controllers.
Mixers also are used for Carry Over between presets, even with your analog delay or reverb.
2 volume values can be stored for each preset.
• 2 function switches via one TRS jack. You can control the switching functions of your amp.
• 640 presets (160 banks x 4 presets) and 1 global preset.
• Switches can be assigned to the user's preference.
• Create up to 480 songs.
• Organize the 480 Songs into 60 sets of 48 songs.
• Clickless function for reducing popping noise.
• ISO OUT that prevent to occur ground hum noise and phase issue.
• Transmits 12 MIDI (PC, CC and Note) messages, when a preset is changed.
Transmits 4 MIDI (PC, CC and Note) messages when the switches assigned to pages are pressed.
• Transmits MIDI Timing Clock and synchronizes with Function Switch1/2.
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, songs, sets and switches.
• 2 Lines x 16 Characters LCD display that can display preset/song titles and other status.

P1 through P4 switches
On the Page 1, these switches are used to recall the corresponding preset. When on other pages, pressing these switch
turn on/off the corresponding effect loops, function switches, ouputs, buffers, etc.
TAP switch
TAP can be synchronized with MIDI Time Clock(MTC) or Function Switches(F1/F2). The Function Switches support for
devices that only have an analog tap tempo input. Also you can select whether or not to send the MTC.
Tapping the TAP switch will change the MTC or F1/F2 rate to the tempo of your taps.
At this time, the Global.BPM will be changed to the tempo of your taps.
The Global.BPM is changed by tapping the TAP switch is applied to the current bank or song. In other words, the
Preset.BPM stored in the current bank or song is ignored.
When the EFX-LE II powers up, the Global.BPM is 120.
PAGE switch
Pressing this switch puts the EFX-LE II into the other page, where you can turn individual loops on and off, and store
their settings to presets.
On the page 1, pressing & holding this switch for 1 second will execute/cancel the MUTE function.
On other pages, pressing & holdingthis switch for 1 second will store the edit and return to the page 1.
Factory setting provides up to 4 pages, and up to 6 pages can be used depending on the user's preference.
BANK▲& BANK▼switches
The 640 presets in the EFX-LE II are arranged in banks of 4, and these buttons allow you to select which bank of 4
you’d like to access. Pressing this switch in Preset mode increments/decrements the bank number.
Pressing the BANK▼switch while pressing the BANK▲switch increases the bank number by 10.
Conversely, Pressing the BANK▲switch while pressing the BANK▼switch decreases the bank number by 10.

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
Latched 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 pedal or 2 external foot-switches(normally Open Type) can be connected to this jack using a 1/4” TRS
cable. The TRS cable must be connected before supplying power to the EFX-LE II. 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 II without any changes.
DC12V Power Connector
This is the main power input for the EFX-LE II. The EFX-LE II requires a DC12V power supply.
The current draw is approximately 200mA at DC9V (Center Negative).
