The Radial Engineering Workhorse SixPack Desktop Power Rack comes in a pack of 6 and is designed for the 500 series modules. It lets you mix and match up to 6 modules and safely power them to create a stereo channel strip or unique signal chain.

The design begins with a heavy 14-gauge steel construction and baked enamel finish. This provides extra durability when moving the SixPack around the studio while also providing better shielding against stray magnetic fields. To reduce induced noise, the external power supply is connected using a 5-pin locking XLR. To ensure positive contact, the module card-edge connector is mated to a double sided EDAC 15-pin receptacle that is 100% compatible with the old API pin format. Extra safety is built-in to ensure malfunctioning modules will not harm the racks or other modules that are already connected. And with 1,600 mA of shared current, the SixPack offers 265 mA (average) per slot to ensure even the most power-hungry tube modules are satisfied.

Rear panel connectivity includes individual XLR input and output connectors wired in parallel to 1/4" TRS connectors. These may be used as mults or for cross-patching various modules together to create innovative sounding signal paths. A set of 25-pin D-Sub connectors enable this rack to easily integrate with a Workstation. Two XLR connectors are front mounted and may be routed to the D-Sub or to inputs 1 and 4 to make patching in a microphone more expedient. Extra features include a feed switch that patches one module into the next, a link switch to combine stereo-ready modules and Omniport, and a 1/4" TRS jack that adds extra functionality.

The convenient design lets you set the Workhorse Desktop Power Rack down on your work surface or carry it around the studio using the side-mounted handle. The flanges (sold separately) let you mount it in a 19" (48.3cm) rack if you plan to take your SixPack on the road.


6-Space Rack
Fully compatible with older 500 series racks, the SixPack gives you 6 spaces to allow enough room for creating elaborate signal chains.
Safety Circuits
Built inside all Workhorse SixPack racks, there are special safety circuits for each module to protect the rack and adjacent modules from mishap.
Mil-Spec PCB
Double-sided military grade circuit board with through-hole parts that are soldered on both sides to improve the performance. It also features full ground plane that reduces the noise.
Solid Steel
The SixPack has a 14-gauge steel construction for durability and improved shielding.
Carry handle to make it easy to lug your SixPack around the studio.
Alignment Tray
The SixPack makes it easy to slide modules in and out by providing a vertical alignment tray. It accommodates several modules and can be removed if required.
Standard 19" Rack
Suited for recording studios, broadcast stations, and live touring; the SixPack fits all standard 19" racks using only 3 spaces (3RU).
Power LEDs
Front panel LED indicators provide a visual status (or both ±16 V rail voltage and 48 V phantom power.
Inputs 7 & 8
Convenient front panel access jacks let you connect a source to your workstation using channels 7 and 8 on the D-Sub connector. These may also be routed to inputs 1 and 4 for added convenience.
Front Panel XLR Assign
Lets you assign the front panel XLRs to either feed channels 7 and 8 via the D-Sub or route the XLRs to channels 1 and 4 inputs to create channel strips.
Stereo Link
Unlike older racks that require soldering, linking 2 channels in stereo is done by sliding the LINK switch in the up position.
XLR Connectors
Standard XLR connectors with large channel ID numbers on each slot make it quick and easy to patch with professional balanced line level gear.
Feed Function
The SixPack eliminates the need for inter-module patch cables with an innovative FEED function that sends the output from one module to another.
External Power
To keep noise out of the box, the SixPack employs an external supply just like full-size studio mixers. A 5-pin XLR is used to secure the power cable.
This 1/4" TRS jack changes function depending on what module is connected. This function is determined by the manufacturer.
1/4" TRS Connectors
1/4 " Inputs and outputs on each slot are wired in parallel with the XLRs. It is used to cross-patch modules using standard TRS cables for parallel processing.
Using the SixPack to Build a Stereo Channel
Use the SixPack's 6 slots in a 3 + 3 format to create the ultimate stereo channel strip. Combine a PowerTube preamp with a Q4 class-A EQ and a Komit compressor and you have everything you need to get the job done.

Using the SixPack on the Road
Fill the SixPack for your next session by recording directly using a JDV instrument preamp Q3 coil EQ and Komit compressor. Combine this with a microphone using a PowerPre microphone preamp, Q4 parametric EQ, and a PhazeQ to phase-align both channels.

Using the SixPack as a Side Car
Build the ultimate analog side car to warm up those digital tracks. Start with two Q4 class-A semi parametric EQs and then phase align the 2 channels with the PhazeQ. Add an EXTC to bring in a guitar pedal, Reamp out using the EXTC, and frequency divide a track using the Tossover.
