Frequently Asked Questions - Workhorse Shuttle Radial Engineering

Can I use the Shuttle in a non-Radial 500 series rack?

Yes, the Shuttle works in any standard 500 series rack. Loop-1 (balanced) is always available. Loop-2 (unbalanced) and Omniport require a Radial Workhorse rack.

What is the purpose of the Loop-1 Insert switch?

The Loop-1 Insert switch lets you bypass the effect loop to compare the wet (with effect) and dry (without effect) signals instantly.

How do I connect an outboard effect processor?

For balanced devices, use Loop-1's TRS Send and Receive jacks. For unbalanced devices, use Loop-2's unbalanced jacks. Turn off power before connecting.

What does the Omniport do?

The Omniport is an unbalanced insert loop (Tip Send, Ring Return) available only in a Radial Workhorse rack. It connects to external effects or a patchbay using a single TRS cable.

Can I use the Shuttle to bring an external line-level source into the Workhorse mixer?

Yes: connect to Loop-1 or Loop-2. Loop-1 routes to the rear XLR output and mixer buss; Loop-2 routes directly to the mixer. Use the insert switch to turn the signal on/off.

How do I set up an overdub monitor mix?

Send playback from your DAW to the Shuttle's input (use two Shuttles for stereo). The Shuttle routes it to the Workhorse mixer where you can blend with a mic preamp signal. Monitor via headphones or the mixer's outputs.

What is the FEED function on the Workhorse?

The FEED switch routes the output of an adjacent 500 series module to the Shuttle, then to the Workhorse mixer without external patching. Ideal for chaining modules.

What are the power requirements?

The Shuttle draws only 5 mA from the 500 series rack's power supply.

Does the Shuttle change the signal level?

No, it provides unity gain (0 dB). The signal passes through without amplification or attenuation.

What is the warranty period?

Radial offers a 3-year transferable limited warranty covering defects in materials and workmanship.

OVERVIEW

The Radial Shuttle is a patch point module that enables you to bring signals in and out of the Radial Workhorse and other 500 series modules. Think of it as a convenience device. In other words, it enables you to perform a number of functions via front panel connectors that otherwise would require rear panel patching or re-routing. Some of the functions the Shuttle enables include playback routing for overdubbing, direct input from music players or other audio sources, effects routing and for those with a Workhorse, easier integration of older 500 series modules and rear panel connectivity to a remote patch bay.

Shuttle Used In Older 500 Series Racks

When the Shuttle is used in a non-Radial 500 series rack LOOP-1 is available through the balanced input and output. LOOP-2 will also deliver an unbalanced signal via the Shuttle front panel SEND jack.

GETTING STARTED

Before making any connections, start by turning off your audio system and turning all volume levels down. This helps protect equipment from turn-on transients that could damage loudspeakers and other sensitive equipment. We recommend using a power bar with an on-off switch as this makes it easy to turn on and off the 500 series rack, monitors and so on, using a single switch. Carefully plug the Shuttle into your 500 series rack to avoid stress on the card edge connector. Screw the module in to ensure it does not accidentally become dislodged.

Most 500 series racks are equipped with XLR connectors. When you plug the Shuttle into your 500 series rack, it will automatically route the input and output to the module. With the Workhorse, this is augmented with 14 TRS connectors, D-Subs and a signal to feed the Workhorse mixer. It also activates the Omniport which in this instance turns the Omniport into an unbalanced TRS type insert.

USING THE LOOPS

The Shuttle can be used in any standard 500 series rack. There are some added features that Workhorse users can enjoy. The easiest way to discover the Shuttle's functionality is to go right to applications. This way, you can determine a need and then connect the Shuttle to address it.

Balanced Patch Point

Professional level (+4dB) balanced studio devices are usually much quieter than unbalanced devices and thus preferred by recording engineers. Often, particular processors will be brought into the studio for special effects or maybe mastering. Patching these into a studio setup usually requires pulling racks apart, disconnecting cables and so on.

The Shuttle makes this process easy by allowing you to connect the output from your workstation or other 500 series module to the XLR inputs on the Shuttle (via your 500 series rack or via the FEED switch on the Workhorse) and then using the 1/4 TRS connectors on the front panel to route the signal to and from the effect. The Shuttle's output can then be sent back to your workstation or to the Workhorse mixer. Use the insert switch to turn on or off the effect for quick comparisons between the wet and dry signals.

Unbalanced Patch Point

For those equipped with a Workhorse 500 series rack, a second loop is available via front panel 14 " unbalanced SEND and RECEIVE jacks. The most common method of routing effects in the studio is via an unbalanced effects insert. This of course is common to all recording consoles, but is not always convenient with today's digital recording workstations. The Shuttle brings the convenience of front panel patching to your Workhorse.

Connect the source signal to the Shuttle via the Workhorse and the signal will automatically be routed to the LOOP-2 front panel 14 ” connectors. The Shuttle is equipped with internal buffers that will properly unbalance the signal so that your effect device will get the proper level and impedance. Use standard guitar type 14 ” cables to route the signal to and from your effect device. Once the signal is received back into the Shuttle it is routed to the internal mix buss and the Workhorse mixer section. The front panel on-off switch lets you bypass the loop so you can compare the wet and dry signals.

UNBALANCED PATCH POINT USED IN THE RADIAL WORKHORSE RACK

Omniport Insert Patch Point

For those equipped with a Workhorse, a third loop is available via the Omniport connector. This 14 " TRS connector follows the standard tip-send, ring-return and is ideally suited for routing signals to a favorite effects device such as a limiter or to a remote patchbay. This sends an unbalanced signal to the effects device and returns the wet signal using the same cable.

THE OMNIPORT FEATURE IS ACCESSED ON THE REAR PANEL OF THE WORKHORSE RACK.

The Omniport Insert is wired in series with loop one and two. This enables you to combine as many as three loops together in series to create dramatic effects. And as with the other two loops, you can engage the insert loop using the front panel switch or turn it off to compare the wet and dry signals.

Using The Shuttle With Non-Radial Modules And The Workhorse

Each card-slot in the Workhorse rack is equipped with a function called FEED that essentially replaces an XLR cable. This routes the signal from one module into the next to enable the engineer to set up elaborate channel strips or crazy effects. Because the FEED function frees up the XLR connectors these can still be used for even more elaborate routing or for sending dry tracks back to the recording system for later Reamping™.

As soon as you plug in your module, the FEED function will route the signal through the Shuttle, onto the Workhorse internal buss and into the mixer section. This enables the engineer to take full advantage of the Workhorse mixer without having to patch the signal via the D-SUB summing mixer input. To use the FEED function simply install the Shuttle in a card-slot to the right of the older 500 module, engage the FEED switch on the Workhorse and you are set to go.

Overdubbing Using The Workhorse

A common concern when using digital workstations is latency. This is a delay caused by the time it takes the recording system to process the new track and combine it with the existing track. Although this is getting better, for some, latency causes a sense of detachment. Thus most prefer to record in the analogue domain.

The Workhorse mixer and Shuttle module can be configured to provide a monitor mix while recording overdubs. For instance, when overdubbing a vocal track you send a pre-recorded mix of tracks from your workstation and connect it to the Shuttle's input (two Shuttles are used for stereo). The Shuttle routes the workstation playback signal to the Workhorse mixer where it is mixed with the signals from one or more microphone preamps like the Radial PowerPre™. You can use the mixer channel controls to quickly set up and adjust a monitor mix. Headphones can be connected directly or you could use the mixer's balanced outputs to drive an amplifier and power several sets of headphones. To record the overdub track the output from the mic preamp is sent directly to your recording system via the card slot I/O.

Patching External Sources

The Shuttle's two front panel loops are capable of being used as secondary (alternate) inputs to enable line-level sources such as keyboards, CD players, DJ mixers or drum machines to easily connect to the Workhorse mixer section and directly to your workstation. The routing options are different depending on which loop you connect to.

Loop-1

Patching into Loop-1, for instance, will route an external signal to the card slot's rear panel balanced XLR output. If the Shuttle is installed in a Workhorse the signal is also routed to the mixer section via the mix buss. Use the LOOP-1 INSERT switch to turn the external signal on and off.

Loop-2

Patching into LOOP-2 will route an external signal directly to the mixer section via the Workhorse mix buss. From there, the signal may be routed to the mixer's MAIN and MONITOR outputs to connect a balanced +4dB signal back to your workstation or you can simply monitor with headphones right from the mixer front panel. You can use the LOOP-2 INSERT switch or the mixer channel ON switch to turn the external signal on and off.
