Mackie 1202-VLZ4 オーナーマニュアル

Owner’

s Manual

These balanced outputs are capable of delivering 22

dBu into a 600 ohm balanced or unbalanced load.

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.

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 processing on channels 5 through 12, simply patch
through the processor before you plug into  
the 1202VLZ4.

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, our Onyx
mic preamps have become so famous, that people buy
these mixers just to have four of these in their arsenal.

This stereo jack will drive any standard headphone  

to very loud levels. 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.”

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.

Engaging this switch reduces the level of the  

balanced 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.)

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),  
soloed channels, or the tape input. The volume is  
adjustable with the control room/submix [34]knob.
