Are your teeth really so-brilliantly-white that you can't stand it? Do all the  
popular kids all giggle as you walk past on the beach? Me too. Ever thought about 
a career as a technical writer?

For optimum sonic performance, the channel fad-

ers and the MAIN MIX fader should be set near the “U” 
(unity gain) markings.

Always turn down the MAIN MIX fader and CONTROL 

ROOM and PHONES knobs before making connections 
to your 1642-VLZ3, or turning PHANTOM POWER on.

If you shut down your equipment, turn off your ampli-

fiers first. When powering up, turn them on last.

Save the shipping box! You may need it someday.

Here’s how to get going right away, using a 

 microphone and a keyboard: 

1.   Plug your microphone into Channel 1’s MIC 

input.

2.  Turn on the 1642-VLZ3.
3.   Perform the Level-Setting Procedure. 
4.   Connect cords from the MAIN OUT jacks to 

your amplifier. 

5.   Hook up speakers to the amp and turn it on. 
6.   Set channel 1’s fader to the “U” mark.
7.   Engage (push in) Channel 1’s L/R switch.
8.   Set the MAIN MIX fader one-quarter of the way 

up.

9.   Sing like a canary! 
10.  Plug your keyboard into channels 3 and 4. 
11.  Turn channel 3’s PAN knob fully left and chan-

nel 4’s PAN knob fully right.

12.  Set those faders to the “U” mark.
13.  Perform the Level-Setting Procedure.
14.  Engage the L/R switch on these channels.
15.  Play like a madman and sing like a canary! 

We realize that you must have a powerful han-
kerin’ to try out your new 1642-VLZ3. Or you 
might be one of those people who never reads 
manuals. All we ask is that you read this page 

NOW, and read the rest later— you’ll be glad you did.

WARNING: Before you plug the AC power 
cord into the mixer, make sure the VOLTAGE 

SELECTOR switch is set to the same voltage 

as your local AC mains supply (see page 13). 

Message to seasoned pros: do NOT set levels using the 

old “Turn the trim up until the clip light comes on, then 
back off a hair” trick. When a Mackie mixer clip light 
comes on, you really are about to clip.

This procedure really works — it assures low noise 

and high headroom. Please read on.

It’s not even necessary to hear what you’re doing to 

set optimal levels. But if you’d like to: Plug headphones 
into the PHONES output jack, then set the PHONES 
knob about one-quarter of the way up.

The following steps must be performed one channel at 

a time:

1.  Turn the GAIN, AUX send and fader controls 

fully down.

2.  Be sure the 1–2, 3–4 and L/R channel assign-

ment switches are all disengaged.

3.   Set the EQ knobs at the center detents. 
4.   Connect the signal source to the MIC or LINE 

channel input.

5.   Engage (push in) the channel’s SOLO switch.
6.   Push in the MODE switch in the output section 

(LEVEL SET (PFL) mode) — the LEVEL SET 
LED will light.

7.  Play something into the selected input, at real-

world levels.

8.   Adjust the GAIN control so that the display on 

the meter stays around “0.” (Only the left meter 
is active in the Level-Setting Procedure.)

9.   If you’d like to apply some EQ, do so now and 

return to the previous step.

10.  Disengage that channel’s SOLO switch. 
11.  Repeat for each channel.
