What is the benefit of having a Decoder when I can set up my mixer and re-patch some cables?

In a word: simplicity. The Decoder makes it super easy to set up M/S tracks and sounds amazing!

What kind of microphone preamps are inside the Decoder?

These are the same low-noise op-amps as used in some of the Radial 500 series modules.

Can I use the Decoder as a standard mic preamp?

Yes of course. It is perfectly suitable for use as a 2-channel mic pre.

Can I mix two mics to one output using the Decoder?

Yes. Simply use inputs 1 and 2b and audition from the left output.

Can I use the Decoder with a ribbon mic?

Yes. There is 65dB of Gain available which is more than sufficient for most ribbon mics.

Can I use the Decoder with my Radial DI box?

Yes. It will work with both active and passive direct boxes.

Why is the 48V phantom switch recessed?

To prevent accidental misuse. Turning phantom on when signals are up can cause a loud pop that can blow tweeters. If an old ribbon mic is connected, it could also blow the mic's element.

Can I rack mount the Decoder?

Yes. Rack mount kits are available from your Radial dealer.

Can I connect the Decoder to a powered loudspeaker?

Yes. The balanced line level output has plenty of Gain for any line level destination.

Why does the Decoder employ an external power supply?

Although no one likes these devices, they are beneficial as they allow the Decoder to be used around the world by simply changing the power supply. Further, the PSU is often the primary cause for system breakdown. So replacing the PSU is easy. Finally, by taking the PSU out of the metal box, you can reduce noise. Improving the signal-to-noise ratio allows the Decoder to be used with low output ribbon mics.
