Thank you for purchasing the Radial Twinline™. The
Twinline is an innovative device that enables you to route
your effects to two amps when using their rear-panel effect
loops.
As the Twinline requires a signicant number of cables and
is equipped with remote controllability, it is well worth taking
the time to read through this manual before you get started.
This will not only ensure proper connections are made, but
it will also help you optimize the signal path for best tone
and least distortion. If after you have read this manual you
still nd yourself asking about a feature or function, please
visit the Twinline FAQ page located on our website. This is
where we post answers to questions and where we often
post product updates. If you still have questions that are
left unanswered, feel free to send a note to info@radialeng.
com and we will do our best to reply in short order.
Now get ready to roll up your sleeves and start patching!

INTRODUCTION
The Twinline is basically a switcher that lets you toggle your pedalboard
and effects between two ampli ers using their rear panel effects loop. In
other words, you can have one set of pedals and then route it to either
of your two amps so that you do not need to duplicate your pedalboard
setup.

TWINLINE PEDALS
Before you start to reach for your cables, you should consider your amp
and effects setup and prepare your connections based on how you
intend to use them. Furthermore, it is good practice to turn off all of
your audio equipment and ampli ers before making connections. This will
prevent plug-in or power-on transients that could damage more sensitive
components. Once you are ready, and have made the connections, you
can plug in the Twinline’s 15VDC power supply. This turns on the Twinline
as there is no power switch. A handy cable lock may be used to secure
the cable in place.

CONNECTING THE TWO LOOPS
When making connections, ensure you are using high quality coaxial
unbalanced guitar cables with ¼” connectors. Good quality cables help
reduce noise while retaining signal integrity. Try to keep the cables as
short as possible. You will need at least six (6) guitar cables for the basic
hookup.
Start by connecting the two amp’s effects loop to the Twinline:
1. Connect the effects loop SEND from your rst ampli er to the Twinline
FROM AMP A input.
2. Connect the TO AMP A from the Twinline to your rst ampli er’s effects
loop RECEIVE jack.
FROM AMP A’S EFX LOOP OUTFROM AMP B’S EFX LOOP OUT
TO AMP A’S EFX LOOP INTO AMP B’S EFX LOOP IN
3. Connect the effects loop SEND from your second ampli er to the
Twinline FROM AMP B input.
4. Connect the TO AMP A from the Twinline to your second ampli er’s
effects loop RECEIVE jack.

Next, connect your pedalboard (guitar effects) or studio processors to
and from the Twinline:
1. USING UNBALANCED GUITAR PEDALS:
a. Make sure the rear panel effects select switch is set to the UNB
(unbalanced) OUT position. This switch is recessed to prevent
accidental switching.
b. Connect from the Twinline SEND to the input of your rst pedal.
c. Connect from your last pedal to the Twinline RECV (receive).
2. USING A BALANCED STUDIO PROCESSOR:
a. You will need two balanced XLR cables.
b. Set the rear panel effects select switch to BAL (balanced) IN position.
c. Connect from the Twinline XLR SEND to the input of your processor.
d. Connect from your processor to the Twinline RECV (receive) XLR
input.

Select loop-A using the A-B switch on the Twinline front panel. The LED
indicator will illuminate to let you know which channel is active. Bypass
your effects by setting the FX ON switch to the OFF (OUT) position – this
LED will go off. Slowly bring up the volume on your rst amp and test.
Always test at low volumes to ensure things are working before turning
up. This can help eliminate turn-on or connection transients from cables
that may not be seated correctly.
Once you have conrmed the signal is passing, activate the Twinline by
depressing the FX ON switch. The LED will illuminate. You can now play
using your effects. It is a good idea to use a clean effect such as a delay
or chorus to set the levels. If you hear distortion, reduce the SEND level
on the Twinline and then adjust the RECEIVE level for gain make-up. If
the sound seems thin… increase the SEND level to suit. You cannot harm
pedals by overloading them, they will simply distort.
It is important to note that when combining various products together
such as amps, switchers and pedals, it takes a bit of ddling to get the
levels to work properly. Be patient and try different settings. Take notes
on your setups by using the handy setup page at the end of this manual.
This reference will surely come in handy when changing or trying various
setups.
You are now ready to test the second amps effects loop. To do this, select
Amp-B using the front panel AB switch, bypass the effects for testing (FX
switch out) and then if all is good, reactivate the effects (FX switch -in).
Set your levels to suit this amp and you are now ready to rock!

GETTING STARTED
You are now ready to power up. Make sure the volume levels on your
amps are turned down before turning them on. Plug in the Twinline’s
power supply, turn on your amps. Set the send and receive loop controls
on the Twinline to 12 o’clock. If your amp has variable level controls, they
should be set to the manufacturer’s recommended setting to start.

THE POLARITY REVERSE
Both of the Twinline effects loops are equipped with a polarity ‘invert’
switch. Some ampliers will invert the phase as it goes through the signal
path. Correct this by depressing the PHASE INVERT switch. When out of
phase, one amp will sound more distant then the other.
RACK MOUNTING THE TWINLINE
The Twinline may be rack mounted using the optional SA rackmount
kit. This allows either one or two of the Radial Stand-Alone (SA series)
modules to be used side by side and only requires a single 19” rack
space for mounting.

REMOTE CONTROLLING THE TWINLINE
There are two ways to toggle the effects loop between the amps. The
easiest is to use the front panel AB select switch. This works great in
the studio when you are not under the pressure of doing quick switches
during a live show. However, if you consider all of these cables going
back and forth to the Twinline and your amps, when playing live, it is best
to keep the Twinline near your amp where you can hide the cable mess
and keep the cables as short as possible in order to reduce susceptibility
to noise.
The Twinline is able to be remotely controlled in a number of ways.
This includes using a standard latching footswitch, a Radial-equipped
Slingshot pedal, using the optional JR2 or SW2 remote footswitches or
the contact closure from a MIDI controller.
USING THE OPTIONAL JR2 REMOTE
The Radial JR2 is a dual footswitch remote that can toggle the AB loops
and bypass the effects altogether. It receives current from the Twinline to
power its LEDs thus providing visual status at your feet. Connection from
the JR2 is accomplished using a standard ¼” TRS cable.
