1) Carefully remove the four screws holding the bottom plate.
2) Remove the bottom plate gently.
3) Replace the old battery with a new one of the same type, 9V alkaline
type; 6LR61.

The EBS Phantom Power System™ makes it
possible to power the EBS UniChorus with 9V
DC directly from the EBS Drome, Gorm, Fafner
and 1V2/Classic amps. Here is a step-by-step
instruction on how to do this.

a switch on most EBS amps. Please consult the manual for the EBS

EFFECT MIX LEVEL
The EBS UniChorus pedal is equipped with an effect mix trimmer, FX MIX,
for further fine-tuning your sound. This function makes it possible adjust
the amount of the pure chorus signal to mix in with the normal “bypassed ”
sound. The range can be set from 0% to 100% mix, where 0% is off. The
factory setting for this trimmer is set to 50%.
The trimmer is located on the printed circuit board, and is easily accessible
by removing the bottom plate. When doing any adjustments, please use a
plastic screwdriver, and turn this trimmer gently.
If you are not 100% sure on how to do this, please
consult your nearest service center. Excessive
force may result in damage to the unit, and the
warranty in that case will be void.

Note that only the pedal that is directly connected to the EBS amp can be powered
with phantom power. This means that if you have more than one pedal, ONLY THE
LAST one can use the EBS Phantom Power™.
Checkpoint
1) Is a ¼” STEREO cable used between
the pedal and the amp?
2) Is there power available on the
RING connection of the ¼” plug?
Action if answered NO
- Replace cable to a ¼” STEREO cable.
- Make sure the phantom power is
activated on the amp.
- Check cable.
*EBS recommends the use of the EBS AD-9
,
which supplies a well stabilized power to the EBS UniChorus
and all your other pedals that operate with a 9V battery. The
high current capacity, 650mA, makes it possible to supply all
pedals with only one adapter, EBS AD-9!
