Decoder Mid/Side Matrix and Mic Preamp
About the Decoder
Quick and easy mid/side recording without a mixer
Three ultra-quiet built-in mic preamps
Pre-mixed stereo outputs
Line level operation for use with pre-recorded tracks
The Radial Decoder is a microphone preamp and mid/side stereo matrix that allows the user to easily create M/S recordings without having to re-configure a recording console. Featuring built-in mic pre’s with phantom power and independent level control, the Decoder automatically combines the signals to a stereo output using the sum-difference method for spectacular stereo imaging that translates well to mono for broadcast.
The Decoder begins with three ultra-quiet microphone preamps. The mic/line input-1 is assigned to the MID or direct microphone, while mic/line input-2a is assigned to the SIDE microphone. A link button automatically duplicates and pans the signal and flips the phase for a traditional M/S stereo image when used with figure-8 microphones. Mic/line input-2b allows the Decoder to be used with a pair of cardioid microphones rather than a figure-8. This opens up the door for a variety of microphones and different spacing techniques to be employed for ultimate convenience and creativity. The Decoder can also be switched to +4dBu line level for Reamping? pre-recorded material during mix-down. Simply record a SIDE microphone while tracking and bounce to a stereo M/S image later.
As the Decoder is intended for use in the studio or in the field, the chassis is built out of heavy duty 14-gauge steel. The internal I-beam frame and book-end construction prevents premature damage to internal circuitry and protects knobs and switches from impact. A full bottom no-slip pad provides electrical insulation and mechanical isolation to reduce mishap. The chassis can also be rack- mounted on its own or with other Radial products using an optional rack kit.
