MONO OUTPUT

It happens to everybody sooner or later:
The forces that govern your world will demand
a monaural output from your painstakingly-
created stereo panorama. The last thing you
want to do is start twirling all your carefully-
placed PAN settings to one side. What to do?

end to Mr. Mono, and you're done. He's got his
mono mix and you've still got your stereo mix.
The MONO output is nothing more than a
sum of the left and right MAIN MIX.

MONO LEVEL

So, Mr. Mono comes running back, scream-
ing about the mono mix being so loud that his
camcorder is melting. Just reach for this knob
and turn it down a bit. Just the thing for send-
ing mono signals to mic inputs like camcorders,
telephone interface boxes, even answering
machines. With the pot all the way up (fully
clockwise), you'll have 6 dB of extra gain with
unity gain halfway between the one and two
o'clock positions.

POWER CONNECTION

Just in case you lose the cord provided with
the 1642-VLZ PRO, its power jack accepts a
standard 3-prong IEC cord like those found on
most professional recorders, musical instru-
ments, and computers. At the other end of our
cord is — get this — a plug! Not a black cube
or, as we're fond of calling them, a "wall wart."
We did this for some very good reasons:
The 1642-VLZ PRO has sophisticated power
requirements that a wall wart cannot provide.
Wall warts are inconvenient, fragile, radiate huge
hum fields, hog extra jacks on your power strip
and get in the way. If you lose a wall wart, you're
in trouble, but if you lose the 1642-VLZ PRO's
power cord, you can get a new one at any elec-
tronics, music, or computer store. You can even
buy them at Radio Shack
Plug the 1642-VLZ PRO into any standard
grounded (3-pin) AC outlet or into a power
strip of proper voltage.
WARNING: Disconnecting
the plug's ground pin can
be dangerous. Please
don't do it.

FUSE

The 1642-VLZ PRO is fused for your (and
its own) protection. If you suspect a blown
fuse, disconnect the power cord, pull the fuse
drawer out (located just below the cord re-
ceptacle) and replace the fuse with a 1A SLO
BLO, 5x20mm, available at electronics stores or
your dealer (or a 0.5A SLO BLO 5x20mm if
your 1642-VLZ PRO is a 220V-240V unit).

POWER SWITCH

You can leave this switch on all the time;
the 1642-VLZ PRO is conservatively designed,
so heat buildup isn't a problem even in 24-
hour-a-day operation. You may notice that the
1642-VLZ PRO feels quite warm but there's
nothing that will burn out or get used up.
