FEATURES
BUILT-IN MIXER
The PAC750/PAC770 incorporate a built-in mixer that includes inputs
and control for the built-in Tape and CD players, the stereo Aux input,
and the 4 mono Mic/Line inputs. The Aux input allows an unbalanced
stereo line level source to be connected. The 4 mono Mic/Line inputs
allow either a microphone (either high or low sensitivity) or line input to
be connected. EQ and pan controls are provided on those inputs to
allow for feedback elimination and mixer customization.
AUTO DUCKING
The PAC750/PAC770 incorporate an Auto Ducking feature that allows
the Mic/Line inputs to work in conjunction with the Tape, CD, and Aux
inputs. With the Auto Ducking feature set to -15dB, everything works as
normal except for when any of the Mic/Line inputs has an active signal.
When this occurs, the Tape, CD, and Aux inputs drop down in level by
-15dB. When Auto Ducking is set to -∞, the Tape, CD, and Aux inputs
are dropped out completely when the Mic/Line inputs are active.
VOICE REDUCTION
The Tape, CD, and Aux inputs to the mixer contain a Voice Reduction
circuit that can effectively reduce the vocal tracks in most music. Please
be aware that results vary according to the music and the way it was
recorded.
AMPLIFIER (PAC770)
The PAC770 contains a powerfull amplifier that allows versatile speaker
connection. The 1/4" connectors are very convenient for portable use
while the binding posts allow connection of single-ended banana plugs
or a secure bare wire connection.
TEMPO CONTROL
The PAC750/PAC770 CD player allows for the adjustment of the playing
speed (Tempo) from -50% to +50%. This feature is similar to Pitch
control except that the Key (musical pitch) of the CD output does not
change when the Tempo is adjusted.
KEY CONTROL
The PAC750/PAC770 CD player allows for the adjustment of the Key
(frequency/musical pitch) from -1 octave to +1 octave during playback.
This feature allows the music to be adjusted in order to match correctly
to an instrument or a voice.
A-B LOOP
The PAC750/PAC770 allows two points within the CD to be selected and
the audio within these points will be repeated until a stop command is
issued.
SINGLE TRACK PLAY
The PAC750/PAC770 can be set for the CD player to play the selected
track and then stop and cue up the next track.
AUTO CUE
This feature allows the CD player to advance to the beginning of the
audio within the track rather than start from the track start flag. This
feature helps to minimize the silence at the beginning of a CD track.
PITCH CONTROL
The PAC750/PAC770 tape player allows for adjustment of the playback
pitch (key + tempo) from -12% to +12%. The feature is particularly useful
to tune a tape to accompanying instruments and choirs.
QUICK OPTICAL AUTOREVERSE
In addition to the normal tension reversing circuitry the PAC750/PAC770
tape transport also employs optically sensing quick autoreverse circuitry. This circuitry reacts to the clear areas of the tape, usually the
leader tape, and when detected will reverse the direction of the tape
transport. This process minimizes the lose of signal being recorded or
played back. This reverse process applies to all tape playback and
recording modes, including autoreverse and continuous mode.
DOLBY NR SYSTEMS
The Dolby Noise Reduction systems compress and amplifies the input
signal during recording in order to raise the signal-to-noise ratio on the
tape. During playback, these signals are expanded and attenuated by
the same amount in order to regain the original dynamic range of the
music. An additional result of this expansion and attenuation is that the
noise floor of the recording is reduced significantly. Dolby B typically
reduces noise by 10dB and Dolby C typically reduces noise by 20 dB.
DOLBY HX PRO HEADROOM EXTENSION
The Dolby HX PRO system monitors the total amount of effective bias
during recording and instantaneously compensates for any excess bias
by reducing the tape deck’s bias signal level accordingly. The system
operates independently on each channel. HX Pro is unlike a noise
reduction system because it functions only during recording and no
decoding is required. Therefore a tape recorded with the HX Pro system
can be played back on any other cassette deck while retaining the
benefits of HX Pro.
ONE TOUCH DUBBING
The PAC750/PAC770 allows dubbing of the CD to the tape with one
button start control. This feature allows manual or automatic record level
control.
RC5 REMOTE CONTROL COMPATIBILITY
The PAC750/PAC770 comes equipped with an RC5 remote in and out
port. Through the use of various remote control options, major functions
of the unit can be operated via wired or wireless remote control.

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.
G, 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
