MU1705 USER’S MANUAL
CHANNEL STRIP DESCRIPTION
Two inputs are available to the
mono input channel, via an XLR
con nec tor (normally for mi cro -
phone sourc es) or a 3-pole 1/4”
phone jack for high er level signals
such as key boards, drum ma-
chines, synths or tape machines.
Both in put sock ets are permanently
active, and may be used by sim-
ply plug ging the source into the
required input. You do not need
to unplug something from the mic
sock et if you want to use the line
input. When both the mi cro phone
and line sig nals are plugged into
any chan nel from CH1 to CH5,
then the cir cuit will au to mat i cal ly
be switched to line source.
An unbalanced INSERT is offered
which is a break point in the input
channel signal path. It allows the
signal to be taken out of the mixer,
through an external device and
then brought back into the con-
sole to con tin ue through to the
fi nal output. The insert is a 3-pole
1/4” phone jack, which is normally
by-passed.
When a jack plug is inserted, the
sig nal path is broken at a point
just
after the high pass fi lter, but before
the EQ section. The signal from the
channel appears on the TIP of the
phone plug and is returned on
the RING. The in sert point allows
com pres sors, limiters, effect and
oth er signal pro cess ing units to
be added as required to particular
in put chan nels and be cause it is
lo cat ed PRE EQ, noise gen er at ed
by the ex ter nal equip ment may be
1. GAIN
This rotary knob adjusts the chan nel
signal level. Too high, and the signal
will distort as it over loads the channel.
Too low, and the level of back hiss will
be more noticeable and you may not
be able to get a high enough signal
lev el to the out put of the mixer. Proper
gain or gain set tings allow the mix er to
work at the best operating level. Adjust
the gain when there is a signal present
to the high est lev el without trig ger ing
the peak LED. That is the most ap-
pro pri ate po si tion.
This gain adjuster has two in di ca tions
to match ei ther a microphone or line
in put signal. When you use the mi cro -
phone input, please refer to the in side
ring from 0~+60 dB; but when you use
line input, please re fer to the out side
ring from -20~+40dB.
If you use a condensor microphone, it
is required to send phantom pow er to
it. The global phantom power switch
is lo cat ed on the rear panel.
All faders (Group 1, Group 2, Mono,
L/R and CH1~11) should be all the
way down when you switch on the
phantom pow er. In or der to pre vent
excessive noise to stage mon i tor
speak ers and main speak
ers,
phan tom powered mics should be
plugged in after the phan tom power
is switched on.
2. EQUALIZERS
These equalizers are designed to
suit different room acoustics, control
feed back and improve the live PA
sound. No amount of equalization will
cor rect the fre quen cy response curve
of a poor loudspeaker. Always begin
with all con trols in the “0” po si tion and
avoid ex ces sive ly cutting/boost ing
