5 SENS

This knob sets how much of the source signal is sent to the rest of the mixer. Too

high, and the signal will distort as it overloads the channel. Too low, and the level of any

background hiss will be more noticeable and you may not be able to get enough signal

level to the output of the mixer.

Setting the knob to the `U mark gives unity gain for the LINE input. Note that some

sound equipment, particularly that intended for domestic use, operates at a lower level

(-10dBV) than professional equipment and will therefore need a higher gain setting to

give the same output level.

See `Initial Set Up on page 16 to learn how to set SENS correctly.

6 100HzHI-PASS FILTER

Pressing this switch activates a steep 18dB per octave filter which reduces the level of

bass frequencies only, and is a real bonus for a such a small mixer. Use this in live PA sit-

uations to clean up the mix, reducing stage rumble or `popping from microphones.

7 EQUALISER

The Equaliser (EQ) allows fine manipulation of the sound, particularly to improve the

sound in live PA applications where the original signal is often far from ideal and where

slight boosting or cutting of particular voice frequencies can really make a difference to

clarity. There are three sections giving the sort of control usually only found on much

larger mixers. The EQ knobs can have a dramatic effect, so use them sparingly and listen

carefully as you change any settings so that you get to know how they affect the sound.

HF EQ

Turn to the right to boost high (treble) frequencies above 12kHz by up to 15dB,

adding crispness to cymbals, vocals and electronic instruments. Turn to the left to cut by

up to 15dB, reducing hiss or excessive sibilance which can occur with certain types of

microphone. Set the knob in the centre-detented position when not required.

MID EQ

There are two knobs which work together to form a SWEPT MID EQ. The lower

knob provides 15dB of boost and cut, just like the HF EQ knob, but the frequency at

which this occurs can be set by the upper knob over a range of 240Hz to 6kHz. This

allows some truly creative improvement of the signal in live situations, because this mid

band covers the range of most vocals. Listen carefully as you use these controls together

to find how particular characteristics of a vocal signal can be enhanced or reduced. Set

the lower knob to the centre-detented position when not required.

LF EQ

Turn to the right to boost low (bass) frequencies below 60Hz by up to 15dB, adding

warmth to vocals or extra punch to synths, guitars and drums. Turn to the left to cut

low frequencies by up to 15dB for reducing hum, stage rumble or to improve a mushy

sound. Set the knob to the centre-detented position when not required.

8 AUX SENDS

These are used to set up a separate mixes for FOLDBACK, EFFECTS or recording,

and the combination of each the Aux Send is mixed to the respective Aux Output at the

rear of the mixer. For Effects it is useful for the signal to fade up and down with the

fader (this is called POST-FADE), but for Foldback or Monitor feeds it is important for

the send to be independent of the fader (this is called PRE-FADE).

AUX SEND 1

This is always PRE-FADE and therefore most appropriate for foldback or monitor

mixes or external submix.
