4. Gain Setting

It is very important to set each channel’s GAIN knob correctly in order to get

the maximum amount of signal headroom and least amount of noise possible.

Setting the GAIN too low could make that channel too quiet to mix properly,

while setting it too high will cause clipping and distortion. Stereo channels 3/4,

5/6 and 7/8 allow the MIC and LINE inputs to be used in parallel thanks to the

dedicated GAIN knobs for each input. Follow these instructions to set the gain for

each channel and situation:

• Plug the audio source into the channel input (XLR or ¼")

• Sing into the microphone or play the line-level source at the volume you

will ultimately use during recording or performance. If you set the gain

for a vocal mic by saying “check” into it, this gain setting will probably not

be as loud as the actual vocal performance. Setting the gain this way will

lead you to set the gain too high, which may cause the extra loud vocal

performance to overload and distort. Likewise, if checking a mic that will

record a saxophone, make sure the performer plays close to the mic while

setting the gain. For keyboards, do not change the output volume of the

keyboard after the mixer’s gain has been set

• Turn the GAIN knob clockwise until the red CLIP LED lights up. This means the

channel has begun to overload (too much signal is allowed in)

• Turn the GAIN knob counterclockwise a small amount, then sing or play

again. Ideally, the GAIN knob should be set as high as possible while allowing

the CLIP LED to only light occasionally, if at all

If you must use both the MIC and LINE inputs on channels 3/4, 5/6, or 7/8, you

can adjust the gain setting for each source individually thanks to the dedicated

GAIN knobs. The channel fader aects the level of both sources, so achieving a

good balance between the 2 inputs can be tricky.

• Set the gain for the MIC input using the GAIN MIC as described above

• Set the gain for the LINE input(s) using the GAIN LINE as described above

• Both GAIN knobs share the same CLIP LED, so when both sources are in use at

the same time, neither input should cause the LED to light. If this happens,

turn each GAIN knob down one at a time to determine which is overloading

• Raise the channel fader so that both sources are audible in the overall mix.

Ideally, they will already be balanced and not require further adjustment

• If one source is too quiet with the fader turned up, turn the louder

source’s GAIN knob down a bit, then raise the fader to the appropriate level.

DO NOT simply turn the quiet source’s GAIN knob up until it is loud enough,

as this will likely cause clipping and distortion

4.1 Using external eects

The 1002B lets you use external eects processors to add a touch of reverb,

delay, or other eects to various channels. Use the channel FX knobs, FX SEND

knob and FX SEND jack to send a portion of the signal from several channels to

an eects processor. You can insert the “wet” signal back into the mix through

one of the stereo channels. The FX signal from each channel is sent “post-fader,”

meaning that as you change the channel’s volume, you also change how much

of that channel’s signal is sent to the eects processor. This ensures that the

mix of wet and dry signal remains the same as you adjust the channel volume.

Follow these steps to incorporate external eects in your mix:

• Connect a ¼" TS cable from the FX SEND jack to the input of the

eects processor

• If you would like the eects to operate in stereo, connect ¼" cables from the

left and right outputs of the processor to one of the stereo input channels on

the 1002B

• For mono operation, most processors return a mono signal through the

left output. This mono signal should then be routed into the left input

on one of the mixer channels. If possible, use channel 9/10 since it only

allows line inputs

• Turn the FX SEND knob to the center (12 o’clock) position

• Turn the channel FX knob up for each source to which you would like to

apply eects. For example, you can add a lot of reverb to a vocal mic, while

only adding a small amount to a snare drum. This will just be a preliminary

setting as you will not be able to hear the eect yet. Keep the knobs around

the center position; you will ne-tune them shortly

• Adjust the input gain for the channel receiving the output from the

eects processor. (See the Gain Setting section for details.)

• Turn the channel fader up to 0 on the channel receiving the signal back from

the processor. DO NOT turn the FX knob on that channel up at all! Your sound

system will become haunted with screaming banshees

• You should now hear the selected eect on the channels that are sending

signal to the processor. Adjust the channel FX knobs to get the eect

mix just right

• NOTE: The processor will likely have its own VU meters to monitor the

incoming signal level. If the processor’s meter begins clipping, turn down the

FX SEND knob on the 1002B

See the Applications section for details.
