Radial’s Decoder MS Interface Is Now Shipping

Radial Engineering Ltd. has recently announced that the Decoder, a self contained MS (mid-side) interface, is now shipping.

The Decoder makes it easy to create exceptional stereo imaging when combining a stereo mic with a second middle microphone. Radial Product Specialist, Ryan Juchnowski explains: “When we started working on the Decoder, we knew full well that a savvy engineer can pull together an MS patch using a traditional console, but we felt that there are a number of users who would prefer to have a simple ‘plug and play’ kit to do the job. Once we got started, we had so much fun during audio tests that we became convinced this would be a real treat to use for those with smaller studios where patching facilities may be limited or for those who plan to Reamp using pre-recorded tracks.”

The Decoder begins with three XLR inputs with input-1 for a center mic, and input-2 (a) for a single output figure 8 mic or 2 (b) for those using two cardioid mics. Individual on-off switches and level controls for all three inputs are conveniently located on the front panel. A recessed 48V phantom power switch may be activated to supply DC for condenser microphones. A high-pass filter may also be engaged to eliminate excessive low frequency rumble and improve stereo focus. When using two separate microphones to create a figure 8 pattern, a 180° switch is engaged to reverse the polarity of mic 2B. Top mounted selector switches enable the Decoder to be used with microphones or line level sources when applying MS imaging to pre-recorded tracks.


The Decoder is made from 14 gauge steel to handle the abuse of being on the road. A unique book-end design creates a protective zone around the front panel switches and potentiometers keeping them safe from overzealous roadies. The internal I-beam construction is tremendously rigid to assure the sensitive internal PC board will not torque – thus preventing premature development of cold solder joints.

The Decoder may also be rack mounted by using the optional Radial SA rack-mount kit.

MAP for the Decoder is $349.99 USD.
