THE INTERFACER
MANUAL

The Interfacer is all about professionalism. It’s about setting your
board up like the pros to be ready for any situation. Two amps. One
amp. Ground loops. Phase issues. Long cable runs. Buffer sensitive
pedals. The Interfacer handles all of these scenarios with ease. It
even has a master mute for when the proverbial hits the fan. Think
of it as a Swiss Army knife for your pedal board, except it’s made in
Australia, it’s black, and it’s a guitar pedal.
Let’s look at the most common way of connecting The Interfacer.

TUNER

If you have a vintage fuzz or wah, or any pedal that doesn’t
like being after a buffer you can use the passive input first. It’s
important to return to the buffered input if you want to take
advantage of the always-on tuner send.

PEDAL
The passive through can also be used to quickly and conveniently
patch an expression pedal or tap tempo switch into a pedal on your
board. Simply connect the pedal’s exp jack or tap jack to the P send
on the left side of The Interfacer, and then any time you want to
have expression or tap control connect the appropriate device to
the P in on the right side of The Interfacer. It is compatible with TS
and TRS connections.

TUNER

Master mute
This is situated at the very end of the circuit before the locking
jacks. Use it to tune silently, as a kill switch for song transitions
without delay and reverb trails, or if you need to troubleshoot your
board without sending unwanted noises to FOH.
The Interfacer can power up muted or un-muted, the choice is
yours. To change this, hold down the foot switch, plug in power and
then immediately release the footswitch.
The LED is on when muted and off when un-muted.
Summing
Hold down the footswitch for two seconds to switch between
stereo and dual mono. The LED will change colour – red is stereo
and blue is dual mono. You can switch modes whether muted
or un-muted. When muted the LED will change colour. When
un-muted the LED will flash the colour that represents the mode
you’re switching to. If it flashes blue, your amps are receiving dual
mono. If it flashes red, they’re receiving true stereo. Changing
modes when un-muted does not activate the master mute
function.
The Interfacer features DMS™ which stands for Dual Mode
Summing. Unique circuitry, designed by Goodwood Audio, that
provides two types of summing, Stereo Sum and Split Sum. The
default setting is Stereo Sum.

Stereo Sum
Use this mode when the last pedal in your signal chain is stereo.
When the LED is red, you will have a true stereo signal being sent to
your amplifiers. When the LED is blue, the left and right signal being
sent by your last pedal is combined to mono, and then split to both
outputs – commonly referred to as dual mono. This is useful if you
only have one amp at rehearsal, but two amps live. Use blue mode
when you only have one amp to preserve your stereo ping pong
delays, and then switch to red mode for when you have two amps.
When you’re playing live with two amps and one dies, simply hold
down the footswitch and the repeats of your ping pong delay will be
combined to both outputs. It doesn’t matter which amp dies and
you don’t have to stop playing and use a hand to flick a toggle or
push a button.
Split Sum
This mode is best suited to people who run a mono pedal board,
but like using two amps. To change to this mode take the lid off the
box and move the two dip switches from Stereo Sum to Split Sum.
Connect your last pedal to the L return of The Interfacer and keep
it in blue mode. This will create a dual mono signal. If you switch
to red mode the L output will stay active, but the R output will
have no signal.
Ground Lift & Phase Correction (The TX Interfacer only)
The TX Interfacer features red and black push buttons.
Press the red button to lift ground of the right output. Press the
black button to invert the phase of the right output by 180°
For phase inversion to work ground lift must be active – red button
pushed in.
