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 affects 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. 

The 1002B lets you use external effects processors to add a touch of reverb, delay, 

or other effects 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 effects 

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 effects 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 effects in your mix:

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

effects processor.
If you would like the effects 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 effects. 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 effect yet. Keep the knobs around 

the center position; you will fine-tune them shortly. 
Adjust the input gain for the channel receiving the output from the effects 

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 effect on the channels that are sending 

signal to the processor. Adjust the channel FX knobs to get the effect 

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.
