6Channel Inserts 1–4

These jacks, lurking on the back of the MicroSeries 1202, are where you connect series processors such as compressors, equalizers, de- essers, or filters (or as mic preamp direct outs). Since most people don’t have more than a few of these gadgets, we’ve included connections for just the first four mic/line inputs. If you want to use this kind of processing on Channels 5–12, simply loop through the device before you plug into the MS 1202.

The insert points are after the mic pre- amps, but before the channel gain knobs and equalizers. The output at this connector is low impedance (120Ω), capable of driving all processors; the input is high impedance (over 10kΩ) and buffered, capable of being driven by almost any processor.

We’ll discuss other aspects of channel inserts including their use as direct channel outs on page 12.

THREE SETS OF MIX OUTPUTS

The MS 1202 has three obvious sets of outputs: the main stereo mix (7); a screamingly -loud stereo headphone jack (8); and a tape recorder connection (9) all of which receive the total mix consisting of the eight channel strips plus the two STEREO AUX RETURNS. Main outputs and tape outputs are affected by the MASTER control; headphone output has its own control.

7Main Output

These outputs are electrically balanced and capable of driving +4dBu lines with up to 28dB of headroom. They’re also low

impedance and can drive as low as a 600Ω line. Balanced output is 6dB higher than for unbalanced outputs. (This is noted on the Master Gain Pot by a special U BAL mark counterclockwise from the “U” center detent position.)

To use these outputs in balanced applica- tions, connect a TRS phone plug:

Tip	= + (hot)
Ring	= – (cold)

Sleeve = Ground

For most music recording and PA applica- tions, unbalanced outputs are perfectly acceptable. Use standard instrument cables.

To use these outputs in unbalanced appli- cations, connect a mono phone plug:

Tip = + (hot)

Sleeve = Ground

8Headphone Output

The stereo PHONES jack will drive any standard headphone to very loud levels. Walkperson-type phones can also be used with an appropriate adapter.

If you’re wiring your own cable for the PHONES output, follow standard conventions:

Tip	=	Left channel
Ring	=	Right channel

Sleeve = Common ground

Headphone warning: When we say the headphone amp is loud, we’re not kidding. It can cause permanent ear damage. Even intermediate levels may be unhealthily loud with some earphones. Be careful!

Always turn the PHONES knob all the way down before connecting headphones. Keep it down until you’ve put the phones on. Then
