3. Mode Description
The EFX LITE 8L Audio Controller utilizes two modes of operation: Preset Mode and Instant Access Mode. On
power-up, the display will show its firmware version, upon which bank 1 and the global preset will be
selected.
3.1 PRESET MODE
The EFX LITE 8L Audio Controller has 60 presets, configured as 15 banks of 4 presets, plus a global preset
which is common to all banks. (Bank : 1, 2, 3, ... , 9, A, B, C, D, E, F)
The Preset Mode is automatically selected when the power is initially turned on.

ྜG The preset is selected via pressing any switches from P1 through P4. The display will stop flashing and
the LED above the switch turns on.
NOTE : If you want to select P1, skip the procedure ྛ~ྜG and press the P1 switch.
The global preset is a preset with all the capabilities of preset 1 through 4, but is the same for all banks.
Pressing the switch of a preset that is already on selects the global preset and will cause the LED above the
switch to turn off.
MUTE
Press &hold the switch of a preset that is already on, for 1 second. The decimal point on the display will

preset.
3.2 INSTANT ACCESS MODE (Programming the Loops)
ྙG Select the preset to be programmed in the Preset Mode.

NOTE : The decimal point on the display will flash until the edit is stored or other preset is selected.
4. Set Latched / Momentary Type Switch
Loop 7 and Loop 8 will act as footswitches like those used for amp channel switching. Normally open and
normally closed operation are selected by plugging into either the OUT7/8 jacks(for normally open), or the
SND7/8 jacks(for normally closed).
Also the EFX LITE 8L Audio Controller supports both standard switch types, latched and momentary.
ྙG Apply power while holding the MODE and P1 switches down to change the switch type of Loop7.
ྚG The display will show 'L' or 'M' and the red L7 LED will turn on, and then the LED above P1 switch will
flash. 'L' means Latched and 'M' means Momentary.
ྛG Press the P1 switch to change the switch type of Loop7.
ྜG This setting will store into the EEPROM memory and the EFX LITE 8L Audio Controller will automatically
restart.
ྜྷG Follow the same procedure ྙ~ྜG for Loop6. In case of the Loop8, The switches are MODE and P2.
NOTE : The initial default setting is 'L'
5. Popping Noise Reduction Control
The EFX LITE 8L Audio Controller is based on relay switching. This method is utilized to route the audio
signal with absolutely no tone coloration or degradation. The disadvantage of relays is that they can produce
a slight popping noise when they switch on/off. The Popping Noise Reduction Control is excellent for
reducing this popping noise.

ྛG Press the P3 switch to turn Popping Noise Reduction Control on/off.
ྜG This setting will store into the EEPROM memory and the EFX LITE 8L Audio Controller will automatically
restart.
NOTE
- To use the Popping Noise Reduction Control, connect the MUTE OUT jack to the amplifier input jack. Refer
to the basic connection drawing on page 2.
- The initial default setting is 'n'
6. Initial Default Setting
The initial default setting for the EFX LITE 8L Audio Controller may be reset with the following procedure.
This procedure will erase all user data from the EEPROM memory.
ྙG Apply power while holding the P1 and P4 switches down.
ྚG The display will show 'd' and the LED above P1 switch will flash. 'd' means Default.
