Fast-Track “CAN’T WAIT!” tips for people who ignore manuals

A.To adjust input levels:

1.Set TRIM fully counterclockwise.

2.Set GAIN to unity (twelve o’clock).

3.Push in the INPUT CH. METERING switch.

4.Feed a normal signal into a selected input.

5.Adjust that input’s TRIM control so that the display on the left LED strip stays around 0, and never goes higher than +10.

6.Repeat for each of Channels 1– 4.

B.Connecting effects

Read the section starting on page 11 for full information on connecting digital delays, reverbs, etc. via AUX SENDS and STEREO AUX RETURNS. This can get pretty complicated quickly.

Don’t cream your monitor speakers

Always turn the master gain and headphone level controls down before making connections to and from your MS 1202.

INTRODUCTION

Thank you! There are a lot of makes and models out there, all competing for your bucks … but you have voted with your wallet for the folks in Woodinville who specialize in American-made mixers.

There are only two other things we ask: First, now that you’ve got a MicroSeries 1202, find out how to get the most from it.

That’s where this manual comes in.

•If this is your first pro mixer, flip through the whole book: you’ll find it full of actual from-the-streets engineering tips, as well as operation and installation instructions.

•If you’re an experienced, big-bucks engineer with lots of fader hours under your fingertips, at least read “Part 1: All the Holes and Knobs.” (We’ve found that experienced engineers usually read manuals cover-to-cover anyway so that they can keep getting the big bucks.)

Part 1 — ALL THE HOLES AND KNOBS:

A GUIDED TOUR OF THE MICROSERIES 1202

The first thing you’ll notice is that the top panel is organized into three distinct areas:

•A patchbay along the top;

•Eight channel strips — four mono and four stereo;

•And an output section on the right.

Note that four patchbay jacks overflowed the top panel, and are on the rear of the

MS 1202. The following pictures will help you find everything; the next few pages will help you use it all.

PATCHBAY

At the risk of stating the obvious, this is where you plug everything in: microphones, line-level instruments and effects, headphones, and the ultimate destination for your sound: a tape recorder, PA system, etc.

1 Microphone Inputs

We use true “phantom-powered, balanced inputs” just like the big studio mega-con- soles, for exactly the same reason: this kind

of circuit is excellent at rejecting hum and noise. You can plug any kind of professional mic that has a standard “XLR-type” male mic connector. If you wire your own, connect them like this:

Pin 1 = Ground or shield

Pin 2 = Hot (in phase with output) Pin 3 = Cold (out of phase with output)

Professional ribbon, dynamic and condenser mics will all sound excellent through these inputs, especially if you follow the Level Setting instructions on page 12. Lowercost electret-type unbalanced mics can be plugged into Line Inputs 1–12, but will require additional gain.

Basically, the MS 1202’s inputs will handle any kind of mic level you can toss at them without overloading. But you’ll get the absolute best quality sound if you follow the calibration procedure covered briefly in our “Can’t Wait Tips” on page 3, and more depth in Part 3, page 12.

Microphone Power

Most modern professional condenser mics are equipped for Phantom Power, which lets the mixer send low-voltage DC to the mic’s electronics over the same wires that carry audio. (Semi-pro condenser mics often have batteries to accomplish the same thing.) The “Phantom” owes its name to an ability to be “unseen” by dynamic mics which don’t need external power and aren’t affected by it anyway. NOTE: Do not apply phantom power to ribbon microphones, or you will have an entertaining fireworks display.

The MS 1202’s phantom power is controlled by the PHANTOM switch on the rear panel.

2 Ch. 1–4 Line Inputs

Line inputs 1–4 are a good place to connect older keyboards which have low gain, or keyboards in general since you can adjust the corresponding channel TRIM control so that the mixer has plenty of gain but you can keep the keyboard volume control set around the halfway mark.

3 Trim controls

TRIM 1 through 4 adjusts the input sensitivity of the mic and line inputs connected to Channels 1 through 4. This allows signals from the proverbial outside world to be brought in at optimal internal operating levels. See Level Setting instructions on page 12.

4 Chs. 5–6, 7–8, 9–10, 11–12 Line Inputs

These four line inputs share circuitry (but not phantom power) with the mic preamps, and can be driven by balanced or unbalanced devices at almost any level. In other words, you can use these inputs for virtually any signal you’ll come across, from instrument levels to levels of –10 to +4, since there is 40dB more gain available than on Channels 5–12.

		ring			shield
	tip	sleeve	cuff	hem garter belt	(ground)
					positive
					(white wire)
					negative
					(black wire)

To connect these inputs to balanced sources, use a Tip-Ring-Sleeve (TRS) or three-conductor plug (the type found on stereo headphones):

Tip	= Positive (+ or hot)
Ring	= Negative (– or cold)
Sleeve	= Shield or ground

To connect the inputs to unbalanced sources, use a mono phone plug or standard instrument cable. The jack on the MS 1202 will sense the plug and disable the balancing circuits.

These inputs are designed for stereo or mono unbalanced signals from –10dBV to +4dBu. They can be used with just about any professional or semi-pro instrument, effect, or tape player. In the audio world, an oddnumbered channel usually receives the “left signal”. For example, feed line inputs 5–6 a stereo signal by inserting the device’s left output plug into the Channel 5 jack, and its right output plug into the Channel 6 jack.

5 STEREO AUX RETURNS to Master

This is where you connect the outputs of your effects devices. The STEREO AUX RETURNS are wired identically to the stereo line inputs. The circuits will handle stereo or mono unbalanced signals, either instrument level, –10dBV or +4dBu. They can be used with just about any pro or semi-pro effect on the market.

Additional information on connecting effects to the MS 1202 starts on page 11.
