19. FUSE

24

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 flat

 

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 find out what to do.

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.

21. POWER LED

You’ve probably already figured 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.

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 condensers 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 phenomenon — 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).
