USING THE DECODER AS THREE CHANNEL MIC PREAMP

The Decoder is perfectly well suited to be used as a two or three channel 

microphone preamp with a mixed mono output. This could be for field 

recording, podium use or other applications where a high performance, 

yet compact mic pre may be required. Because the Decoder is able to 

produce as much as 65dB of gain, it is well suited for condenser, dynamic 

and most ribbon microphones. You can also use the Decoder to power an 

active direct box like a Radial J48. 

1. Connect the first microphone to input-1 and the second microphone 

to input-2b. 

2. Connect the LEFT output to the input of your recording or PA system.

3. Activate the phantom power if needed. The 48V phantom power 

switches are recessed to prevent accidental use. Note: Some ribbon 

mics can be damaged if phantom is present. Please check with the 

manufacturer to ensure safe use.

4. Bring up the GAIN on the two channels as needed.

5. To change the polarity of the second mic, depress the 180° switch, and 

then adjust the level using the 2b GAIN switch. Changing the polarity 

can be used to widen stereo tracks or time-align tracks to bring them 

into focus. Try it!
