HOW TO MINIMIZE AT HOWLING

LAYOUT AND FUNCTION OF INPUT CHANNELS
4
1. MIC INPUT
The channel microphone(1) is a standard 3-pin female(XLR) connector. Pin one is
ground, pin two is signal high(+), pin three is signal low(-), as per the agreed-upon
international standard. When pushing on phantom swich, +48V will be fed to pin
2,3 of mic connector, which is impossible to use unbalanced microphone.
2. LINE INPUT
The channel line input(2) is a TRS (tip-ring-sleeve) balanced 1/4" phone jack, with
ground wired to the sleeve, signal high(+) to the tip and signal low(-) to the ring.
Input variable range is -20dB ~ +20dB according to position of gain control in case
input connecting, tip is '+', ring/sleeve is 'ground'.
3. INSERT
As a route of channel signal change, the tip carries the signal back of the channel
(the return), and the ring carries signal out to the channel(the send). The channel
jack allows you to insert external processing equipment(such as compressor, gate)
into main signal path of the input channel strip. Insert point is located the front of
HPF(100Hz), EQ, Gain controller you can adjust EQ or HPF to minimize hum.
4. DIRECT OUT
The channel direct out is an unbalanced 1/4" phone jack, connected to the output
of the channel line- amp post-EQ/post fader/post-mute the out signal of each
channel strip is always available at the direct out jack using the direct out does not
interrupt the nomal signal flow through the channel. For recording of channel signal,
connect multi track.
6. PAD SWITCH
When pushing PAD switch for supporting gain volume, input sensitivity of mic/line
will be reduced at 40dB.
During the PAD switch pushing, gain control range is limited within 0 marking.
5. PHANTOM POWER (Only for stage pro series)
Microphone phantom(+48V DC) is applied to the channel strips in groups of four.
We suggest that before plugging or unplugging mics, you turn "off" phantom power.
8. Φ(Phase) SWITCH
This is for reverting of mic/line input signal phase at 180 in case of misconnecting
"+, -" connector.
7. GAIN CONTROL
This is for control of mic/line input sensitivity, this control acts as a sensitivity control
covering a 40dB range channel signal level increases as the control is turned
clockwise.
Input sensitivity of mic/line is -20dB ~ +20dB.
Warning : To protect speakers, do not insert conderser mic or pick up under
phantom power on and you can use trans output balanced dinamic mic under
phantom power on.
※
Warning : when CLIP LED indicate red color, you can adjust gain volume with
counterclockwise or can use PAD switch.
9. 100Hz (High pass filter) SWITCH
Locating at the rear of head amp, pressing this switch inserts a 12dB per octave
100Hz (high pass filter) in the signal path immediately after the input amplifier, this
is particulary useful on line vocal, and its use is strongly recommanded, even on
male 2 vocals, it can be used for filtering out low frequency hum.

10.EQUALIZER(HF,MF,LF) SECTION
This is a fixed 12KHz shelving EQ with ±15dB of equalization available. Shelving
EQ works on a very broad range of frequencies and consequently are very musical.
In a 12KHz shelf like this section, that means that all the upper harmonics of a
sound are raised evenly, basically keeping their original musical relationship to
each other. A high freq shelving EQ is great for putting shimmer into acoustic guitar
and piano tracks and sizzle into vocals.
HI FREQ EQ CONTROL
11.EQ IN/OUT SWITCH
The IN switch bypass the EQ when UP. Depress it to enable equalization.
14.GROUP SWITCHS
This is for sending of main output from input channel by selecting of GRP1.2,
GRP3.4,L/RMix.
16.ON SWITCH
The on switch enables all outputs from the channel when pressed, and the
associated LED illuminates to show that the channel is active.
17.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 illuminate 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 fade signal
is FED to the head phone, 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.
15.PAN POT
The pan control determines the position of the signal within stereo mix image
or may be used to route the channel to particular output group as selected by
the routing switchs, rotation fully counterclockwise feeds the signal solely to the
left mix bus or group 1 and 3, while rotation clockwise sweeps the image to the
right bus or group 2 and 4.
12.PRE-SWITCH
With the PRE switch depressed, sends receive their input from a point before
the channel fader and MUTE switch, and are not affected by changes in these
controls. This is a normal configuration for sound reinforcement/live stage
monitor sends and studio cue sends.
13.AUX SEND(1~4)
These control route the input channel signal to anyone or more auxiliary buses.
These are separated from the main output and therefore provide additional
output AUX1 & 2 are drived before the channel fader(pre fader), and are
therefore unaffected by the fader position this makes them particalary suitable
for foldback or monitor feeds, which need to be controlled separately from main
PA, MIX, AUX1,2,3,4 are altered to be post fade.
The mid EQ controls is a variable EQ with ±15dB and variable range is 150Hz~
7KHz this peaking EQ will add or remove or make soft voice and clearance.
MID EQ CONTROLS
The low EQ is a fired 80Hz shelving EQ with ±15dB of equalization avaicable it
is fine bass control a low-FREQ shelving EQ will add or remove bass in a smooth,
musical fashion good for working on bass drum and guitar, fattening up a piano or
contouring an entire mix.
