7. Low cut
If you push the “low cut” button, a filter will be inserted into the
audio chain of the GIG-12 that has a characteristic 80Hz, 18dB/oct
high pass characteristic to cut any undesired low frequencies. This
function can be used to cut the humming sound or to prevent
resonances of low frequencies, when the speakers are placed in
close distance.
8 /9/10. Equalizer section (hi/mid/low)
The mixer’s Equalizer section allows shaping of the incoming audio
signal. All mono input channels are fitted with 3-band EQ. The
hi (8)
and
low (10)
shelving controls have their frequencies fixed at 12 KHz
and 80 Hz respectively. The
mid (9)
range control has a peaking
response frequency at 2.5 KHz. All 3 bands have up to
15 dB cut and boost, with a centre detent for off. Turning an
Equalizer control clockwise amplifies the frequency range, turning
counterclockwisethe attenuates the signal. Minor changes to the
Equalizer control usually produce the best results. Try to avoid
excessive enhancement of the mid band.
11. Channel aux 1
The Aux 1control allows you to adjust the channel’s level to the Aux
bus.
12. Channel pre/post
The pre/ post button toggles the aux 1 signal to be taken pre- or
post- fader.
13. Channel effects
The Effects control allows you to adjust the channels level to the
effect bus.
14. Pan/bal
Mono channels: By using the pan(orama) control you can change
the input signal’s position within the stereo image. When the
pan(orama) control is set to center position, the audio signal is
equal for both the left and right output.
Stereo channels: By using the bal(ance) control you can adjust the
balance between the left and the right channel. If you use a mono
source (input left mono) the control works as a pan(orama) control
and lets you change the input signal’s position within the stereo
image.
15. Clip indicator
The clip indicator shows peak levels in a channel’s incoming signal
level. If the LED frequently blinks or constantly lights, the
corresponding channel is likely to enter clipping and you have to
reduce the input’s amplification using the
gain (6)
control. The LED
lights at a level of 8 dB below clipping. Make sure that the LED lights
only briefly during dynamic peaks.
16. Signal indicator
The signal indicator shows the presence of an audio signal at the
output of the channel.
