14. MIC Inputs
These are female XLR connectors, which accept a balanced microphone input from almost any type of microphone. The microphone preamps feature our new Onyx design, with higher fidelity and headroom rivaling any standalone mic preamp on the market today.
The XLR inputs are wired as follows:
Pin 1 = Shield or ground
Pin 2 = Positive (+ or hot)
Pin 3 = Negative (– or cold)
15. MID/SIDE DECODE
The Onyx 800R has a
When using this technique, connect a cardioid (mid) microphone to channel 1 and a figure 8 (side) micro- phone to channel 2. Push in the MID/SIDE DECODE button, and the left signal from the decoder is sent to the channel 1 output, and the right signal from the decoder is sent to the channel 2 output.
A CLOSER LOOK AT MID/SIDE RECORDING
A number of stereo recording techniques have been developed over the years including Blumlein, ORTF, spaced pair, and coincident pair, of which

2.The signals pass through the decoder just prior to the A/D converters and the analog line outputs.
Stereo recording reproduces the instruments in the same relative locations within the stereo image as they were in the original performance. The side to side stereo image and, to some extent, the front to back depth of image are preserved.
The
Notice that the adjustments are made prior to the decoder. Adjusting the ratio of the left and right sig- nals after the decoder will not have the same effect. If you want to adjust the stereo image later during mixdown, record the raw MID and SIDE signals to tape with the decoder turned off. Then, when you are doing the final mix, run the recorded MID and SIDE signals through channels 1 and 2 with the decoder turned on and experiment with the gain controls on channels 1 and 2 to adjust the stereo image to your liking.
Another benefit of this recording technique is that the stereo recording is mono compatible. This is especially important for broadcast and film produc- tion applications.
