standby mode. It will not function, but the circuits are 
still live. To remove AC power, either turn off the AC 
mains supply, or unplug the power cord from the mixer 
and the AC mains supply.

As a general guide, you should turn on your mixer 

first, before the power amplifier or powered speakers, 
and turn it off last. This will reduce the possibilities of 
any turn-on, or turn-off thumps in your speakers. 

You’ve probably already 

figured this out, but if the 
POWER [20] switch is on, this 
LED (light-emitting do-hicky) 
will light. If the switch is off, 
well, you get the idea. If the 
POWER [20] switch is on and 
the LED does not glow, one of 
three things has happened: 
Somebody tripped over the 
power cord and yanked it from 
the outlet, your electricity has 
been turned off due to nonpay-
ment, or the FUSE [19] has 
blown.

This switch controls the phantom power supply for 

condenser microphones as discussed on page 8. When 
turned on (or off), the phantom power circuitry takes a 
few moments for voltage to ramp up (or down). This is 
perfectly normal.

This is just to let you know which way you have the 

PHANTOM [22] switch set. If your dynamic mics work 
and your condensers don’t, chances are this LED is off, 
so turn the PHATOM switch on.

You’ll notice that when you turn the phantom power 

off, the LED stays on for a while. This is a natural phe-
nomenon — the LED is actually a voltmeter telling you 
that the phantom power takes time to ramp itself down 
to zero volts. So, if you’ve turned phantom power off to 
connect something to the mic inputs, wait until the LED 
stops glowing and then make your connections safely.

Located in the top right corner of the output sec-

tion, this 12V socket will drive any standard BNC-type 
lamp (a Littlite® #12G or #12G-HI (high-intensity), for 
instance).

If Mr. Mono's main mono mix is maxed, just reach for 

this knob and turn it down a bit. Just the thing for send-
ing mono signals to mic inputs like camcorders, tele-
phone interface boxes, even answering machines. With 
the pot all the way up (fully clockwise), you’ll have 6 dB 
of extra gain, and unity gain is at the 12 o'clock position.

WARNING: Before you plug the AC power cord 
into the 1642-VLZ3, you must make sure that 
this slide switch is set to the same voltage as 

your local AC main supply. Only slide the voltage switch 
with the power cord unplugged.

Use a flat headed screwdriver to slide the switch if 

needed. The switch allows you to use the mixer in dif-
ferent countries and voltages, meet interesting people 
from other cultures, and entertain them.

Just in case you lose the cord provided with the 1642-

VLZ3, its power jack accepts a standard 3-prong IEC 
cord like those found on most professional recorders, 
musical instruments, and computers. 

WARNING: Before you plug the AC power cord 
into the 1642-VLZ3, you must make sure that 
the VOLTAGE SELECTOR [17] slide switch is 

set to the same voltage as your local AC mains supply. 

WARNING: Disconnecting the AC mains plug’s 
ground pin can be dangerous. Please don’t do 
it.

The 1642-VLZ3 is fused for your (and its own) protec-

tion. If you suspect a blown fuse, disconnect the power 
cord, pull the fuse drawer out (located just below the 
cord receptacle) and replace the fuse with a 1 A SLO 
BLO, 5x20mm, available at electronics stores or your 
dealer (or a 0.5 A SLO BLO 5x20mm if your 1642-VLZ3 is 
set to 220V-240V).

If two fuses blow in a row, something is very wrong. 

Please call our toll-free number 1-800-898-3211 from 
within the U.S. (or call the distributor in your country) 
and find out what to do. 

Press the top of this rocker switch inwards to turn 

on the mixer. The POWER LED [21] on the top surface 
of the mixer will glow with happiness, or at least it will 
if you have the mixer plugged in to a suitable live AC 
mains supply.

Press the bottom of this switch to put the mixer into
