INTRODUCTION
The Cube is a three card-slot power frame designed for 500 series modules. Up to three
modules may be used at any one time. The Cube routes the modules to the XLR and ¼” TRS
connectors on the rear panel via a 15-pin card-edge receptacle. Radial modules and those
that have been designed by other manufacturers to take advantage of the Workhorse’s extra
features will enjoy the added functionality of the Omniport™.

SIGNAL FLOW
This ow chart shows the basic signal routing. The signal comes into the Cube via the rear
panel XLR female or ¼” TRS inputs. Once the signal goes into a module it is processed and
sent to the male XLR and parallel ¼” TRS output. From here the signal can be routed to the
next adjacent module via the FEED switch connection as described in the next section.
CARD SLOT I/O CONNECTIONS
Each of the Cube card slots is equipped with XLR and ¼” TRS inputs and outputs. The input
sensitivity will be dependant on the type of module being used. For instance if you are using
a microphone preamplier, the input will of course be suited for a low level microphone. If
you are using a dynamic processor like a limiter or an EQ, then the input will usually be set
to handle a professional +4dB balanced line-level signal.

Following 500 series convention, the XLR and TRS outputs usually produce a +4dB balanced
line level signal that is able to feed a professional recording system or line level mixing
console. Put simply, the input level is determined by the type of module being used while the
output level will typically be a balanced +4dB line level signal. If you use ¼” mono cables
you will unbalance the signal. This will reduce the level by about -6dB but everything will still
remain completely functional. Simply adjust the levels to compensate.

FEED SWITCH
As you delve further into the functionality of the 500 series, you will nd that the modular
format allows all kinds of connectivity options. With older 500 series racks, connections
between modules were done using an XLR cable whereby the output from one module would
plug into the input of another. The Cube simplies the process by introducing a FEED switch
on the rear panel. This connects the balanced output of one module to the adjacent module
to the immediate left when viewing the rear panel.

The FEED switch allows you to daisy chain a series of adjacent modules making it easy
to create a customized channel strip whereby a mic preamp feeds an EQ which in turn
could feed a compressor. Changing the order is simply a matter of relocating the modules or
patching using an XLR cable. The UP position turns the FEED connection on.
The ¼” TRS connectors are also great for cross-patching between modules. Think of it like
a patchbay. Simply take the output from one, feed it into another and then jump back. This
opens many creative options and loads more fun.
STEREO LINK SWITCH
Card-slots one and two are equipped with a LINK switch. The LINK function allows modules
that are ‘stereo ready’ to be linked together. A typical example would be using two limiters on
a stereo track where you want the dynamics to be the same for both channels.

OMNIPORT
Omniport™ is a special ¼” TRS jack located on the rear panel that has been left ‘open’
to allow the module to perform a unique task. In other words, depending on the type of
module, the manufacturer can assign the Omniport to perform a function that may be most
appropriate. This could be a key input on a gate, a TRS insert or maybe a buffered output.
As the Omniport function is determined by the module, you will need to consult the module
manufacturer’s specication for details on how it was designed to be used.
SETTING UP THE CUBE
For desktop use, four rubber feet are included in the packaging. To install the rubber feet, turn
the Cube upside down and insert into the four open holes on the bottom.
The Cube also comes with a convenient carry handle that makes it easier to move the Cube
around the studio. You will nd Phillips screws in the package with the handle for mounting.
Leave the handle off if you want to stack stuff on top.
INSTALLING MODULES IN THE CUBE
When making any electrical connection, it is always safer to do so with the power disconnected.
The Cube’s internal power circuit is equipped with protective measures intended to provide a
margin of safety should a module exchange be performed with the power on. However, the
Cube is not designed to allow repeated insertion and removal of modules while the power
supply is active. Always power off the Cube before exchanging modules.

POWER SUPPLY
The Cube employs an external power supply that will automatically convert the various
voltages used around the world and regulate them before sending the power to the Cube.
A standard male IEC/EIN power input connector makes it easy to travel as you need only
change the cable to suit the local power connector type. The connection between the power
supply is a 4-pin locking XLR.
As soon as you connect the Cube, a rear panel LED will illuminate to let you know the power
supply is active. A front-panel power switch and LED indicator will illuminate when turned
on. An additional rear panel LED indicator monitors the 48V phantom power supply when it
is switched on. Turning phantom power on or off is global and applied to all card slots. For
modules such as dynamic processors or EQs that do not use phantom power the module
simply ignores the phantom power as if it were not there.
POWER SHARING
The Cube’s power supply produces 500 milliamps (mA) of current that is shared between the
card slots. So for instance, if you have a power-hungry tube preamp in slot 1 that requires
250 milliamps of current, you still have 250 milliamps of current left to power the other two
card slots. Considering most 500 series modules use between 40 and 130 milliamps of
current, it is unlikely you will ever exceed the Cube’s available power.
Example A:
Slot-1 Radial PowerTube tube preamp Draw: 235mA
Slot-2 Radial Q3 induction coil EQ Draw: 25mA
Slot-3 Radial Komit compressor Draw: 130mA
Total Current Draw: 390mA (110mA to spare!)
Example B:
Slot-1 Radial PowerPre preamp Draw: 130mA
Slot-2 Radial Q3 induction coil EQ Draw: 25mA
Slot-3 Radial Komit compressor Draw: 130mA
Total Current Draw: 295mA (205mA to spare!)
Note: The original API™ spec calls for an average of 130mA for each slot. The Cube exceeds
this with a total of 500mA or 166mA when current draw is divided equally between the three
card slots.

SIGNAL FLOW AND LEVELS
Because the Cube is modular, it can accept a multitude of different devices into it’s card slots.
This also means that you need to understand the signal ow so that you can be sure what
you want to do will work. In the world of audio there are basically four low level signal groups
to contend with before you get to high power output levels such as those produced by power
ampliers to drive loudspeakers.
MIXER
+4dB
-10dB
0dB
NOMINAL
WORKHORSE MIX BUS

MIC / DI

1. MIC LEVEL RANGE: Microphones and direct boxes produce the weakest signals. These
typically range from -60dB to -40dB depending on type. Some such as ribbon microphones
can be as low as -70dB while condenser mics will generally be at the top end of this range.
With a Cube, one would connect a microphone to a preamp like the PowerPre™. This would
elevate the mic-level signal to produce a +4dB line-level at the XLR output.
2. INSTRUMENT LEVEL RANGE: The output levels produced by instruments can range widely. A
single coil electric guitar can produce as little as -40dB while an electronic keyboard, sampler
or digital piano is capable of producing -10dB or more. For low level instruments, 500 series
modules like the JDV™ amplify the signal to produce a +4dB signal level at the XLR output for
direct recording.
3. UNBALANCED -10dB LINE LEVEL RANGE: Unbalanced outputs from CD players, keyboards,
mixers and home hi- components are usually specied at -10dB and are often referred to as
consumer line-level. These connect to a mic preamp. If too loud, one simply engages a pad.
4. BALANCED +4dB LINE LEVEL RANGE: This is the professional line level that comes from a
recording system and is normally the level that goes in and out of EQs and compressors so
most 500 series modules employ a +4dB signal level.
Matching the output level of one device to the input of the next will help you avoid distortion
and maximize signal-to-noise. For instance, using a +4dB output to drive a -10dB input could
overload the input and cause distortion. Conversely, a -10dB output may not have enough
gain to drive the input of a +4dB device resulting in a higher noise oor.
Because each of the Cube slots is equipped with a balanced line level input and a balanced
line level direct output (depending on the module), you are pretty much free to interconnect
modules or route signals to other devices using standard XLR patch cables. Once you start
working with the Cube you will quickly come to understand all of the capabilities and how
easy it is to use.

USING THE CUBE
Because the Cube is a modular frame, there are practically no limits as to what kind of signal
chain you can create. For instance, it can be loaded with Radial modules set up for analog
effects routing for your workstation, a customized channel strip, an instrument preamp for live
recording or as part of a play-back and overdub system.
As with all electronic equipment, turn off the power and turn down levels before making
connections. This will avoid the loud on-off transient that can damage equipment or blow
speakers. Plugging in a module is merely a matter of sliding it into the Cube and carefully
aligning the 15-pin card edge connector. Once plugged in, secure the module in place using
the supplied Phillips screws. After the module is connected, it will automatically route the
signal from the rear panel connectors to and from the module.
Simple XLR I/O
The rst step in approaching the Cube is going back to
the original Lunchbox™. This device was basically a
steel enclosure that fed power to a number of modules.
FROM
MODULE TO
NEXT DEVICE
FROM
SOURCE TO
MODULE
Connecting to and from modules was done using the
XLR connector that was associated with each card
slot. The Cube retains all of this connectivity while
adding the convenience of ¼” TRS connectors.
OUTPUT
INPUT
Setting Up A Channel Strip
The next stage is using several modules together to
create a channel strip. For instance, when recording a
vocal track, you may want to run a mic preamp into an
EQ to add some presence and then into a compressorlimiter so that the track stays out of the ‘red’.
Using the old system, you would connect the microphone to the mic preamp using a standard
XLR cable. The mic preamp output would then connect to the EQ which in turn would connect
to the limiter. The direct XLR output from the limiter would then be sent to the recording
system.

The Cube simplies the process with a FEED switch that replaces inter-module patch cables.
Instead of using an XLR cable, you simply push the FEED switch into the UP position and it
routes the signal to the adjoining module’s input. When engaged, the FEED function sends
the signal to the next module working from left to right (front view). Because the FEED
function is tied to the XLR connector, it will work with new Radial modules and older 500
series modules.

MIC PREAMPEQUALIZERCOMPRESSOR
Once you get started, you will soon nd all kinds of new and exciting ways to patch modules.
You could, for instance, use the feed switch to connect one module into the next while using
a TRS cable to simultaneously patch the signal to the third card-slot. The image below shows
how this is done. The mic signal has been split into two signal paths that can be processed
separately.
