MODE (NORMAL (AFL)/LEVEL SET (PFL))

You may have already seen this, but in case

you missed it: The CR1604-VLZ’s solo system

comes in two flavors:

NORMAL (AFL)

(sometimes

called SIP, or solo-in-place) and

LEVEL SET (PFL)

(sometimes called PFL, or pre-fader-listen).

NORMAL (AFL)

, the soloed

channel’s signal is sent directly to

the

C-R OUTS

PHONES

output

and meter

display just as it would

sound to the channel’s assign-

ment switches: post-

post-fader and post-

PAN

. The

only difference is that

SOLO

works regardless of the channel’s

assignment

positions, and that

makes it really handy — you can

check out a channel before you assign it.

NORMAL (AFL)

is the preferred mode dur-

ing mixdown: If the channel has some

midrange boost at 4.236kHz, is panned a smid-

gen to the left, and its fader is at –5.385dB,

that’s exactly what you’ll hear if you

SOLO

dur-

ing

NORMAL (AFL)

mode. It’s just as if you

took the time to

MUTE

all the other channels.

LEVEL SET (PFL)

solo is the key player in the

all-important

Level-Setting Procedure

. It’ll

send the channel’s actual internal levels to the

meters so you’ll know just what’s going on, level-

wise. This procedure should be performed every

time a new sound source is patched into a

channel’s

MIC

LINE

input jacks.

LEVEL SET (PFL)

is also the preferred mode

for SR (sound reinforcement, or live sound), to

preview channels before they are let into the

mix. It won’t give you stereo placement, but will

give you signal even if the fader is turned down.

Remember,

LEVEL SET (PFL)

taps the chan-

nel signal before the fader. If you have a

channel’s fader set way below “

” (unity gain),

SOLO

won’t know that and will send a unity

gain signal to the

C-R OUTS

PHONES

output

and meter

display. That may result in a star-

tling level boost at these outputs, depending

on the position of the

SOLO

level knob .

LEVEL SET LED

To quote step 6 of the

Level-Setting

Procedure

, “Push in the

MODE

switch in

the output section (

LEVEL SET (PFL)

mode)

— the

LEVEL SET

LED will light.” When the

solo

MODE

switch is engaged, it’s in

LEVEL

SET (PFL)

mode, the mode you must be in to

set levels. Now, when you engage any solo

switch, this LED will be a “green light” to set

levels. If you tried to set levels during

NORMAL (AFL)

mode, the meter

display

would be at the mercy of the channel fader,

and that would be a big problem.

SOLO (LEVEL)

This knob controls the level of the signals

coming from the

SOLO

system. It’s range is off

when fully down, unity at the center detent,

with 10dB additional gain turned fully up. After

the

SOLO

level is determined, the

SOLO

signals

will proceed to take over the

C-R OUTS

PHONES

output and meter display .

Once again,

LEVEL SET (PFL) SOLO

taps

the channel signal before the fader. If you

have a channel’s fader set way below “

”

(unity gain),

LEVEL SET (PFL) SOLO

won’t

know that and will send a unity gain signal to

the

C-R OUTS

PHONES

output and meter

display. That may result in a startling level

boost at these outputs, depending on the

position of the

SOLO

level knob.

RUDE SOLO LIGHT

This flashing LED (light emitting diode)

serves two purposes — to remind you that

you’re in

SOLO

, and to let you know that

you’re mixing on a Mackie. No other company

is so concerned about your level of

SOLO

awareness. We even force the soloed chan-

nel’s

–20

LED to play along, so you can find

that rogue switch fast.

If you work on a mixer that has a

SOLO

function with no indicator lights, and you

happen to forget you’re in

SOLO

, you can eas-

ily be tricked into thinking that something is

wrong with your mixer. Hence the

RUDE

SOLO LIGHT

. It’s especially handy at about

3:00 in the morning, when no sound is coming

out of your monitors, even though your multi-

track is playing back like mad.
