1604-VLZ3
22. PHANTOM SWITCH
This switch controls the phantom power supply for
all the MIC [1] inputs, as discussed on page 9. When
turned on (or off), the phantom power circuitry takes a
few moments for voltage to ramp up (or down). This is
perfectly normal. Make sure that you pull down the mas-
ter fader, and headphone/control room volume before
engaging the phantom switch.
23. 48V LED
Located right next to the POWER LED, this is just to
let you know which way you have the PHANTOM [22]
switch set. If your dynamic mics work and your condens-
ers don’t, chances are this LED is off, so turn it 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.
24. BNC LAMP SOCKET
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).
19. FUSE
The 1604-VLZ3 is fused for your (and its own)
protection. If you suspect a blown fuse, disconnect the
power cord, pop out the fuse drawer with a small fl at
screwdriver, and replace the fuse with a 1A SLO BLO,
5x20mm, available at electronics stores or your dealer
(or a 500 mA SLO BLO 5x20 mm if your 1604-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 fi nd out what to do.
20. POWER SWITCH
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 turn off the mixer,
whenever you feel that this would be a safe thing to do.

guitar solo might not be such a good time.
As a general guide, you should turn on your mixer
fi rst, before the power amplifi er or powered speakers,
and turn it off last. This will reduce the possibilities of
any turn-on, or turn-off thumps in your speakers.
21. POWER LED
You’ve probably already fi gured this out, but if the
POWER [20] switch is on, this LED (light-emitting
diode), located in the output section, will light. If the
switch is off, well, you get the idea. If the POWER 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 nonpayment, or the fuse has blown.
