loed channels, or the Tape input. The volume is adjust-
able with the CONTROL ROOM/SUBMIX [34]knob.

These balanced outputs are capable of delivering 22

dBu into a 600 ohm balanced or unbalanced load.

16. ALT 3–4 OUTPUT

These 1⁄4" outputs are the sum of any channels that

have the MUTE/ALT 3-4 [25] switch pressed in (see
page 13 for the tender details).

These balanced outputs are capable of delivering 22

dBu into a balanced or unbalanced load.

17. CHANNEL INSERT (Channels 1–4 )

These rear-panel jacks are where you connect serial

effects such as compressors, equalizers, de-essers, or
filters. Since most people don’t have more than a few of
these gadgets, we’ve included inserts for just the first
four channels. If you want to use this kind of process-
ing on channels 5 through 12, simply patch through the
processor before you plug into the 1202-VLZ3.

The channel insert points are after the GAIN [4] and

LOW CUT [3] controls, but before the channel’s EQ
[27] and LEVEL [23] controls. The send (tip) is low-
impedance (120 ohms), capable of driving any line-level
device. The return (ring) is high-impedance (over 2.5 k
ohms) and can be driven by almost any device.

See Appendix B for details and drawings about Insert

cables, and a diagram showing three ways to use the
jacks.

Besides being used for inserting external devices,

these jacks can also be used as channel direct outputs;
post-GAIN, post-LOW CUT, and pre EQ. In fact, Mackie
mic preamps have become so famous, that people buy
these mixers just to have four of these in their arsenal.

12. PHONES

This stereo jack will drive any standard headphone

to very loud levels. Walkperson-type phones can also be
used with an appropriate adapter. To learn how signals
are routed to these outputs, see SOURCE MATRIX
[33] on page 16. If you’re wiring your own cable for the
PHONES output, follow standard conventions:

Tip = Left channel
Ring = Right channel
Sleeve = Common ground

WARNING: When we say the headphone
amp is loud, we’re not kidding. It can cause
permanent ear damage. Even intermediate

levels may be painfully loud with some earphones. BE
CAREFUL! Always turn the CTL ROOM/ SUBMIX [34]
knob all the way down before connecting headphones.
Keep it down until you’ve put the phones on. Then turn
it up slowly. Why? “Engineers who fry their ears find
themselves with short careers.”

13. XLR MAIN OUTS

Use these to send the main mix out into the line-level

balanced inputs of your amplifier or powered speakers.

These low-impedance outputs are fully balanced

and capable of driving +4 dBu lines with up to 28 dB
of headroom. This output is 6 dB hotter than other
outputs.

14. XLR MAIN OUTPUT LEVEL SWITCH

Engaging this switch reduces the level of the bal-

anced XLR main outputs by 40 dB, so you can feed the
microphone input of, say, another mixer. (You can safely
connect the XLR outputs into an input that provides 48V
phantom power.)

15. CONTROL ROOM

These 1⁄4" outputs are provided so you can listen

to something other than the main mix. The source is
selected using the SOURCE MATRIX [33] switches (see
page 16). You can choose to listen to the main mix, the
Alt 3-4 stereo bus (see MUTE/ALT 3-4 on page 13), So-
