Mackie CR1604 - VLZ Power Switch, Power LED, Phantom LED, BNC Lamp Socket, Phantom Switch

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 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).

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.
