AYOUT AND FUNCTION OF INPUT CHANNELS
6
14.STEREO INPUT
Stereo inputs have two type of jacks, one is left and right unbalanced RCA jack and
the other is left and right balanced 1/4" phone jack with tip "+", ring "-", sleeve "ground".
15.MONO SWITCH
Pressing this switch, it will be changed into from stereo signal to mono.
In case of same level input, it will be increased at 6dB.
16.GAIN CONTROL
You can adjust input sensitivity of stereo balanced and unbalanced in detail through
gain control.
Variable range is 40dB and stereo input sensitivity range is -20dB ~ +20dB.
It is necessary to adjust gain control for the better noise and headroom.
17.EQUALIZER (HF, MF, LF)
The EQ is consists of three sections the upper control provides H.F 12KHz(treble).
Boost and cut of
±
15dB. Each stereo input is provided with 3 band EQ section.
HF and LF 80Hz are shelving type and MF 2.5KHz is peaking type.
19.AUX SEND (1~2)
Two AUX buses send your signal to internal or external effects, or to a foldback
mix-on-stage. AUX1 is a post-fader send, which can be switched between the internal
DSP and an external feed. AUX2 can be post-fader, pre-fader for effect.
20.BALANCE
BAL control sets the relative mix out of left and right level, in the center position.
It's gain unity. Turning the control fully clockwise increases the right, full counter
clockwise rotation is the left.
22.PFL SWITCH
Pre fader listen let you cue up music on headphone without interrupting the main mix.
CLIP LED is "turn on" and pressing PFL switch, signal is fed to headphone.
23.CHANNEL FADER
This bottom fader determines the proportion of the channel in the mix and provides a
clear visual indication of channel level with "dB" printed normal operating position is
at the "u" mark providing 10dB of gain above that point if required.
You had better to use proposition of channel fader at "u".
21.CLIP, SIGNAL INDICATOR
LED on the channel serves as a clip indicator. To warn when an excessively high
signal level is present in the channel. The CLIP LED will illuminates approximately
5dB before clipping and therefore give warning of a possible overload even if the
peaks are removed by external equipment plugged into the insert. Signal green
LED is -60dB PFL (pre fader). When the PFL switch is pressed, the pre fader signal
is fed to the headphone, where it replaces the selected source, the PFL/AFL LED
on the master section illuminates to warn that the headphones and the meters are
now responding to the PFL/AFL selection. This is a useful way of listening to any
required input signal without interrupting the main mix, for making adjustment or
tracing problem.
18.DSP or DE SWITCH
Warning :
To protect speakers, do not insert condenser mic or pull it out phantom
power on and you can use trans output balanced dynamic mic under phantom
power on.
