Congratulations on your purchase of the Radial Submix, an innovative 500 series module
that lets you mix 4 line level sources such as keyboards, drum machines, effects returns,
computers and just about any other audio source together inside any 500 series rack.
Should you fi nd yourself asking a question that is not addressed, we invite you to view the
Submix FAQ page on our web site. This is where we post the latest hints and of course
questions from users. If you still do not fi nd what you are looking for, feel free to send an
email to info@radialeng.com and we will do our very best to respond to you in short order.
Now get ready to start connecting more cables and wires... cause this is what audio engineers
love to do most!
WARNING NOTICE TO USER!
Although preventative safety measures have been designed into Radial 500 series
products we strictly advise against hot swapping modules or plugging and
unplugging them when the Workhorse or other 500 series rack is powered on. Hot
swapping can cause connection sparks at the card-edge connector that could send
damaging transients to other equipment. This also greatly reduces the life span of the
contacts. Damage due to hot swapping is not covered under warranty. There are no
user serviceable parts inside.

OVERVIEW
The Submix is a four input, one output mixer (4x1) in a single card slot module designed to fi t
the 500 series format. It follows convention with the 15-pin edge connector so that it works in
all 500 series power racks. Each of the front panel ¼” inputs are designed to accommodate
all types of unbalanced line level signals. Examples include instruments such as keyboards,
samplers and electronic drums, plus line-level sources such as tape machines, effects
returns, CD players, iPods, and computer audio outputs. These are then quickly mixed using
the four front panel control knobs.
Typical 4x1 line mixer setup.

1. LEVEL 1 thru 4: Accustate input control,
simultaneously adjusts the sensitivity
and gain for maximum signal to noise.
Use to adjust input levels for each of the
four channels.
2. CHANNEL ID: Easy to read input
channel identifi cation improves workfl ow
effi ciency in the studio.
3. POWER: LED indicator illuminates when
the module is energized by the power
rack.
4. INPUTS: Four separate ¼” inputs to
connect keyboards, drum machines,
effects returns and other unbalanced line
level sources.
5. XLR OUT: The Submix routes the 4
channel mix to the XLR output on your
500 series power rack.
6. OMNIPORT: Designated as a virtualearth mix-buss input, enables multiple
Submix modules to be used together
when used with a Workhorse to create
8x1, 12x1 or larger mixers.

GETTING STARTED
Although the Submix is extremely easy to use, we suggest you follow these simple
instructions before using it. As with all audio equipment, always ensure all levels are turned
down and equipment is turned off before making any connections or inserting the Submix into
a 500 series power rack. This common practice ensures turn-on transients will not damage
more sensitive components such as tweeters. Screw the module in to ensure it does not
accidentally get dislodged.
Making connections
Four high-impedance ¼” inputs on the front panel correspond to the four level controls. Linelevel sources connect to the inputs using standard instrument cables. Mixer channel-1 can
also accept a balanced line signal via the rear panel XLR input jack. However, the front jack
has priority over the rear and inserting a plug into the front channel-1 ¼” input will defeat the
rear XLR input. To use the rear XLR input, ensure the front input is not connected.
The Submix uses the rear panel XLR output for the master mix output. This balanced
line-level signal connects to your recorder or mixing console or to more 500 series signal
processors like the Radial Komit compressor. If you are using the Submix in a Workhorse
power rack, the FEED function can automatically route the output to the adjacent module.

Omniport
If you are using the Submix in a
Radial Workhorse power rack the
Omniport feature will be available.
In this instance with the Submix, the
Omniport acts as a mixer expansion
buss allowing additional Submix
modules to link together to form
larger confi gurations like 8x1, 12x1,
etc. The easiest way to connect
Submix modules would be with a
standard ¼” patch cable from the
fi rst module’s output to the second
module’s Omniport jack.

USING THE SUBMIX IN MONO
Using the Submix will be mostly the same no matter what source is connected so we have
decided to use keyboards as the source to explain the functionality. Start by connecting the
output from your fi rst keyboard to input-1 on the Submix. You will note that the noise level will
remain low at all levels. The Submix employs Radial’s unique VaryState™ gain control that
actually changes the sensitivity along with the gain. Set the level control completely counterclockwise or off to start. Connect the output from the rear panel of your 500 series power rack
to your recording system. Start playing increase the level slowly until you reach a comfortable
listening level. Repeat for input-2.

COMBINING SUBMIX MODULES TOGETHER FOR MORE CHANNELS
If you are equipped with a Radial Workhorse power rack, you can combine two or more
Submix modules together to create larger mixers. Simply connect the TRS output from the
fi rst unit and plug it into the Omniport and the signal will automatically appear on the output
buss to create an 8x1 mixer. Adding a third Submix will give you a 12x1 mixer . Combine these
with a Workhorse Powerstrip, to can create a super compact 12x1 stage mixer!

COMBINING SUBMIX MODULES TOGETHER FOR STEREO
With two Submix modules, you can create a stereo setup by assigning the fi rst Submix to left
and the second Submix to right. When connecting, simply split the stereo signals to follow
suit and you are set to go. This can provide your studio with a very effi cient way of managing
stereo sources such as playback tracks for overdubbing, mixing four stereo keyboards, or
even be used to sum effects or channels together.
