Shuttle™ Using & Applications

The Shuttle™ 500 series module is 100% compatible with older API Lunchbox™ modules and racks while being 'wired' to work with all of the extra features built into the advanced Workhorse 500 series rack and mixer. This short guide is written for those who are experienced with 500 series modules. Complete details on using the Shuttle and making connections to and from your 500 series rack can be found in the manual (PDF download). 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 top end recording engineers. Often, special devices will be brought in for special effects or maybe mastering. Patching these into a studio setup can require 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 ¼" 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


The most common method of routing effects in the studio is via an unbalanced effects send 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 500 series rack or Workhorse.

Connect the source signal to the Shuttle via your 500 series rack and the signal will automatically be routed to the two front panel ¼" connectors. The Shuttle is equipped with internal buffers that will properly unbalance the signal so that your effect device will get the proper signal. Use standard guitar type ¼" cables to route the signal to and from your effect device. Once back into the Shuttle, you can then send the resulting wet signal to your workstations or to the Radial Workhorse mix buss. The on-off switch on the front panels lets you compare the wet and dry signals.


Omniport Insert Patch Point


For those equipped with a Workhorse, a third patch point is available via the Omniport. This ¼" TRS connector is wired following the standard tip send, ring return and is ideally suited for routing signals to a favourite effects device such as a limiter or to a remote patchbay.

Connection is done using either a TRS insert cable or by hard-wiring to your patchbay. This sends an unbalanced signal to the effects device and returns the wet signal using the same cable. The Omniport insert is wired in series with the other two loops. 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.


Overdubbing Using the Workhorse


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

The Shuttle makes overdubbing easy. You send a pre-recorded track to the Shuttle (two Shuttles are used for stereo) and route these to the Workhorse mixer. Then, to record a new track, you set up the desired modules and send this signal output to the Workhorse mixer. Combine all of these via the headphone buss and you are set to go! To capture the new track, simply take the output from the mic preamp or combined channel strip and send this to your recording system.



Using Non-Radial Modules with the Workhorse


The Workhorse 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. And because the FEED function does not use up the XLR connectors (as found on most 500 series racks), these can still be used for even more elaborate routing or for sending dry tracks back to the recording system for later Reamping.

For those with older 500 series modules (circa pre-Workhorse), the Shuttle will automatically route the output to the Workhorse mix buss, enabling the engineer to take full advantage of the features without having to route the signal via the D-sub cable input. Simply position the Shuttle to the right of the older module, turn on the FEED function on the Workhorse and you are set to go.



Patching Signals into the Shuttle


The two front panel insert loops are actually designed to do more than be used as an insert. They are also capable of being used as a secondary input (alternate) to enable sources such as keyboards, CD players, DJ mixers or drum machines to be routed directly into the Workhorse mixer or as a direct feed back to your workstation.

Connect the device to the Shuttle using the balanced or unbalanced input, depress the insert ON switch and you are ready to go. The signal will be sent to the XLR out on your 5500 series rack or automatically be routed to the associated channel on the Workhorse mixer. You are now able to record the instrument or mix it with other devices depending on how your decide to route it.
