REAR PANEL CONNECTIONS
A
AUX INPUT JACKS
These jacks should be connected to the LINE OUTPUT of your
source.
B
LINE OUTPUT (CD, TAPE, PRE-AMP(MIX)) JACKS
These jacks can be connected to the appropriate LINE INPUT of a
power amp, PA or monitoring system.
C
EFFECT INPUT & OUTPUT JACKS
These jacks are used to connect to a graphic equalizer or an effects
processor. When such a device is connected, set the
EFFECT
switch to the ON position. When such a device is not connected, set
the
EFFECT
switch to the OFF position.
¡
If the switch is left ON without anything connected, no audio will be
output through the pre-out or the speakers.
D
MPX FILTER SWITCH
When recording FM broadcasts, set this switch to the ON position to
eliminate the FM carrier signal.
E
REMOTE CONTROL JACKS
These jacks are used with an infrared or wired remote control to
provide remote operation of the PAC750/PAC770.
The signal format of this interface is Philips RC5.
¡
These jacks can be serially linked to provide serial remote control
operation of multiple RC5 equipped products as well.
F
MONO BRIDGE SWITCH (PAC770)
¡
This switch is used to select between mono bridge and stereo
amplified output mode.
When this switch is in the OFF position, the unit functions as a stereo
power amp. When this switch is in the ON position, the unit functions
as a monaural amp. (For details on how to connect the speakers,
refer to page 52.)
¡
This switch only effects the binding post speaker outputs and not the
1/4” speaker outputs.
¡
Make sure this switch is OFF when the 1/4” speaker outputs are
used.

K
AMPLIFIED SPEAKER OUTPUTS (PAC770)
These jacks are used to connect to passive (non-powered) speakers.
When using a speaker system in stereo mode with left and right
channels, connect the right channel speaker to the output terminal
G
labeled “R,” and the left channel speaker to the output terminal
G
labeled “L”. In stereo mode, use a speaker system with an impedance
of 4 to 16 ohms.
When using a single (mono) speaker system, set the
MONO BRIDGE
switch to “ON”. Connect the speaker to the red terminals for both the
“L” and “R” speaker terminals
G
. Do not use the black terminals. In
mono mode, use a speaker system with an impedance of 8 to 16
ohms.
¡
MONO BRIDGE mode is only available on the binding post speaker
outputs and not the 1/4” speaker outputs.
H
FUSE Holder
CAUTION : Disconnect AC power before removing.
This receptacle holds a specific fuse that is used to prevent overload
and shorting.
I
AC TERMINAL
Connect the AC cord that is provided with the unit to this terminal.
J
SPEAKER SELECT SWITCH (PAC770)
This switch is used to select between the two sets of speaker
terminals (
K
and
G
).
¡
Speaker terminals
K
and
G
cannot both be used simultaneously.
¡
Speaker terminal
K
does not permit mono bridge connection.
However, make sure the
MONO BRIDGE
switch is in the OFF
position.
L
EQ & PAN CONTROLS
The recessed EQ controls allow the tone of each MIC/LINE input to
be adjusted to obtain optimum sound quality. Turning each control
to the right boosts the corresponding frequency range and to the left
attenuates it.
LOW : Controls the tone of the lower frequencies. (100Hz)
HIGH : Controls the tone of the higher frequencies. (15kHz)
The recessed PAN control adjusts the MIC/LINE input to the desired
position (L, R or L + R) in the mixing bus.
When the knob is at the center position, the MIC/LINE signal is
centered between the left and right. To position the output on the left
side, turn the knob towards “L”. To position the output on the right
side, turn the knob towards “R”.
M
MIC/LINE INPUT JACKS
Each set of these inputs is designed to accept either a microphone
(MIC) or line (LINE) level signal. All of the input jacks are balanced.
For a microphone level signal, set the MIC
⇔
LINE switch to the MIC
position. For all MIC inputs, set the SENSITIVITY to either HIGH or
LOW, according to the sensitivity of the microphone. If a microphone
that requires phantom power is used with the XLR input, set the
PHANTOM
switch to the “ON” position.
For a line level input, set the MIC
⇔
LINE switch to the LINE position.
¡
The XLR input and the 1/4” input cannot be used at the same time.
N
SYSTEM OUTPUT JACKS (PAC750)
The system output jacks are the final output of the mixer and can be
used when connecting the PAC750 to a power amp, PA, or monitoring
system. The RCA jacks are unbalanced outputs. The XLR jacks are
balanced outputs.
