POWER SWITCH
If this one isn’t self-explanatory, we give up.
You can leave this switch on all the time; the
CR1604-VLZ is conservatively designed, so heat
buildup isn’t a problem even in 24-hour-a-day
operation. There’s nothing that will burn out or
get used up. You may notice that the CR1604-
VLZ’s “pod” feels quite warm (the pod is the
chassis that contains the jacks). This is per-
fectly normal.
POWER LED
You’ve probably already figured this out, but
if the POWER 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 hap-
pened: 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
.
PHANTOM SWITCH
The PHANTOM switch controls the phan-
tom power supply for condenser microphones as
discussed at the start of this section
. When
turned on (or off), the phantom power circuitry
takes a few moments for voltage to ramp up (or
down). This is also perfectly normal. For an
even closer look, refer to Appendix C.
PHANTOM LED
Located right next to the POWER LED in the
output section, this is just to let you know which
way you have the
PHANTOM switch set. If your
dynamic mics work and your condensers don’t,
chances are this LED is off, so turn it on.
You’ll notice that when you turn the phan-
tom power off, the LED stays on for a while.
This is a natural phenomenon — the LED is
actually a yellow 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 in-
puts, wait until the yellow LED stops glowing
and then make your connections safely.
BNC LAMP SOCKET
Located in the top right corner of the out-
put section, this 12V socket will drive any
standard BNC-type lamp (a Littlite
® #12G or
#12G-HI (high-intensity), for instance).
