CONTROLS AND FUNCTIONS
1. [PEAK] LED indicator:
This LED indicator shows the level of the signal input of the channel. The peak
indicator lights up when the input signal reaches 5dB below the channel’s clipping point. This indicator
shows the level of the Post-EQ/ pre-fader signal. If the PEAK indicator lights more than briefly on high-
level transients, you should use the red GAIN control knob to decrease the input sensitivity of the
channel. If this does not work, reduce the output level of the connected source.
2. [GAIN] control knob:
According to the level of the input signal, use this knob to adjust the input signal
to an appropriate level. The best balance of S/N and dynamic range will be achieved if you adjust the
GAIN control so that the peak indicator lights occasionally..
3. [HIGH]:
This knob
adjusts the channel’s high frequency band. Setting the knob to the “0” position
produces a flat frequency response .Turning the knob to the right boosts the corresponding frequency
band ,while turning to the left cuts the band.
4. [MID]:
This knob adjusts th
e channel’s medium frequency band. Setting the knob to the “0” position
produces a flat frequency response .Turning the knob to the right boosts the corresponding frequency
band ,while turning to the left cuts the band.
5. [LOW]:
This knob adjusts the channel
’s low frequency band. Setting the knob to the “0” position
produces a flat frequency response .Turning the knob to the right boosts the corresponding frequency
band ,while turning to the left cuts the band.
6. [AUX] knob:
The AUX knob controls the signal level that the channel sends to the AUX bus. If you are
using stereo channels, the signals from the L and R channels are mixed and send to the AUX bus. The
Post-fader Aux output is also influenced by the channel faders and are mainly used with effect modules.
An AUX SEND master knob is available on the output section
7. [FX] knob:
This knob controls the level of your channel signal that is sent to the internal effect module.
8. [PFL] button:
this button is used to send the pre-fader input signal of this channel to the PFL bus. It
allows you to monitor the input signal through the headphone outputs and the control room outputs, even
when the channel fader is closed.
9. Channel Fader:
This
is the channel’s main level control. It determines the level of the signal that is sent
from the channel to the master mixing and post fader effect busses (AUX and internal effect module). It
is the settings of the input channel faders that determine the mix, or the balance of sound levels between
