EFFECTS: SERIAL OR PARALLEL?

“Serial” means that the entire channel signal

leaves the mixer (insert [12] send), is routed

through the effects device, and returns to the

mixer (insert­ return). Examples: compressor, limiter, graphic equalizer. Line-level sources can also be patched through a serial effects device before connection to the mixer.

“Parallel” means that a portion of the signal in the mixer is tapped off to the device, processed, and returned to a spare channel of the mixer to be mixed with the original “dry” signal. This way, multiple channels can all make use of the same effects device. Examples:­ reverb, digital delay. The internal effects are parallel, as all channels can make use of it, and the processed output is added to the main mix.

16. FX FOOTSWITCH

This 1/4" TRS connector is where you can connect a footswitch. This will allow you to easily mute or un-mute the internal effects, while stamping your foot and looking like you were mad about something. Any one-button on/off footswitch will work.

If the internal effects have already been muted with the front panel mute switch [54] then the footswitch has no effect, but you can still stamp your foot and pout if that helps any. Cultivate that bad-boy image.

17. MON 1 SEND

This 1/4" TRS connector allows you to send the monitor 1 line-level output to stage monitors. These could either be passive stage monitors powered by an external amplifier, or powered stage monitors with their own amplifier built in.

The monitor signal is the sum (mix) of all the channels whose mon 1 control [21] is set to more than minimum. The overall output level can be adjusted with the mon 1 master level [43] and its EQ tweaked with the monitor graphic EQ [41].

The monitor 1 output is not affected by the main master level [38], or the channel level controls [31]. This allows you to set up the monitor mix and level just right, and not have it change every time a channel level or the main mix level is adjusted. This is the main aim of a monitor mix: independence from the main mix.

18. MAIN SUB

This 1/4" TRS connector supplies a copy of the mono main mix below 100 Hz. This is usually patched to the inputs of an external power amplifier running a passive subwoofer, or directly to a powered subwoofer. Whatever adjustments you make to the main mix, will affect this output below 100 Hz.

(The main mix still plays the full frequency range,

line-level. You can connect these outputs to the line-lev-

These outputs play the same signal as the rear-panel

loudspeakers, or to the inputs of powered loudspeakers

 

(or not use them at all, if you don't have the external

 

gear).

 

speaker-level outputs [3] (when set to stereo mains),

 

only at line-level.

 

These outputs can also be used to feed an external

 

stereo effects processor or other device, and have the

 

processed output of that device feed the power amp

 

inputs [20]. This places the device in-line and it will

 

affect the main mix.

 

Another super idea is to use an external

 

active crossover. This splits the line-level main

 

output into two or three frequency bands. The

 

high-frequency output of the crossover could

 

be connected to the power amp inputs [20], so the

 

internal amplifiers will power your top-frequency-range

 

loudspeakers. The active crossover's low-frequency out-

 

puts could connect directly to powered subwoofers. In

 

this way, you can take some of the strain off your pow-

 

ered mixer's internal amplifiers, and have the powered

 

subwoofers crank out the bass.

 

20. POWER AMP INPUTS

 

These unbalanced 1/4" TS inputs allow you to connect

 

line-level signals directly to the input of the internal

 

power amplifiers.

 

The amplifiers will only play what you put in, and only

 

the precision passive EQ switch [47] and limiters [48]

 

will affect the output. The power amp mode switch [4]

 

has no effect, and the meters will not show the levels.

 

Plugging anything in here, does not affect any of the

 

line-level outputs.

 

You could patch a device between the main outputs

[19]and these inputs, in which case, the controls and meters will work except for the power amp mode switch.

These inputs are also useful when you need more channels then the PPM1008 provides. You could connect the line-level outputs from another mixer, and use it to control the mix and levels playing in loudspeakers attached to the powered mixer.

The external mixer or device will control the volume, so turn it down at first, or the powered mixer may come on at full volume.
