Engaging a SOLO switch will cause this dramatic turn of events: Any existing SOURCE matrix selections will be replaced by the SOLO signals, appearing in the control room, headphones and meter display. The audible solo levels are controlled by the SOLO [46] level knob. The SOLO levels appearing on the meter display are not controlled by anything — you wouldn’t want that. You want to see the actual channel level on the display, regardless of how loud you’re listening.

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

The 1604-VLZ3’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).

In NORMAL (AFL), the soloed channel’s signal is sent directly to the control room, headphones and meter display just as it would sound to the channel’s assignment switches: post-EQ [32], post-FADER [25] and post-PAN

[31].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 during mix- down: If the channel has some midrange boost at 4.236kHz, is panned a smidgen to the left, and its fader is at –5.385dB, that’s exactly what you’ll hear if you SOLO during 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 chan- nel’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 [1] or LINE [2] 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

channel signal before the fader. If you have a channel’s fader set way below “U” (unity

gain), SOLO won’t know that and will send a unity gain signal to the control room, headphones, and meter dis- play. That may result in a startling level boost at these outputs, depending on the position of the SOLO [46] level knob.

45. LEVEL SET LED

To quote step 6 of the Level-Setting Procedure , “Push in the MODE [44] switch in the output section (LEVEL SET (PFL) mode) — the LEVEL SET LED will light.”

When the 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.

46. SOLO (LEVEL)

This knob controls the level of the signals coming from the SOLO system. After the SOLO level is deter- mined, the SOLO signals will proceed to take over the control room, headphones, 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 “U” (unity

gain), LEVEL SET (PFL) SOLO won’t know that and will send a unity gain signal to the control room, head- phones, and meter display. This may result in a startling level boost at these outputs, depending on the position of the SOLO level knob.

47. 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 channel’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 easily 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 morn- ing, when no sound is coming out of your monitors, even though your multitrack is playing back like mad.
