OPERATION
The following operating procedures are based on the assumption that
the power is on and that all necessary input and output connections have
already been made. Please refer to the section in this manual marked
“Rear Panel Connections”.
MIXER OPERATION
The PAC750/770 includes a versatile built-in Mixer that allows the output
to be coordinated with the Tape deck, CD player, AUX input, and the four
Mic/Line inputs. Each input to the Mixer has a gain control knob on the
front panel that controls the amount of signal that is added to the mix.
The final output of the Mixer is controlled by the
MASTER VOLUME
knob
@6
, the
EQ
controls
@7
, and the
BALANCE
knob
@8
.
The final output of the Mixer is then sent to the PRE-OUT (SYSTEM OUT
on the PAC750) as a line level signal. On the PAC770, the signal is also
sent to the internal amplifier and then output on the SPEAKER terminals,
which can be attached directly to an appropriate speaker system.
The Mixer In Relation To The Tape Deck
The recording circuitry of the Tape Deck is directly patched into the
mixer, meaning that the Tape Deck will record whatever the Mixer
outputs. Therefore, the final level recorded onto the tape will be determined
by the setting of the Mixer gain controls and the Tape Deck record level
control.
CASSETTE DECK OPERATION
Cassette Tape Playback
1.
Open the cassette holder by pressing the eject button. Load a
cassette tape into the cassette holder and close. The
3
indicator on
the play forward button will begin to flash.

switch to the same position as
the tape was originally recorded in (i.e. tapes recorded with Dolby B
noise reduction need to have this switch in the Dolby B position, tapes
recorded with Dolby C noise reduction need to have this switch in the
Dolby C position, and tapes recorded without Dolby Noise Reduction
need to have this control set to the Off position).
3.
Set the reverse mode switch to the desired position.

Searching For Tracks
While a tape is playing back, pressing the
¡
(Fast Forward) or
1
(Rewind) button will cause the tape deck to forward search for the next
track or reverse search to the beggining of the current track, depending
on the direction of playback.
When the search is concluded, the tape deck will stop.
Notes
¡
For normal Fast Forward and Rewind, the STOP button must first be
pressed.
Rewind & Fast Forward
When the tape deck is stopped, and regardless of the current direction,
pressing the
¡
(Fast Forward) button will place the tape transport in the
high speed fast forward mode and the tape will advance quickly from left
to right. Pressing the
1
(Rewind) button will place the tape transport
in the high speed rewind mode and the tape will retract quickly from right
to left.
In either the fast forward or the rewind mode, the tape transport will
continue to fast forward or rewind until the stop control button is pressed
or the end of the tape or a saved memo point is reached.
Cassette Tape Record
1.
Open the cassette holder by pressing the eject button. Load a
recordable cassette tape into the cassette holder and close. The
3
indicator on the play button will begin to flash. (If you wish to change
the tape direction, press the
2
PLAY
button and then press the
STOP
button).
2.
Set the
DOLBY NOISE REDUCTION
switch to the desired position to
record the tapes with noise reduction (i.e. tapes to be recorded with
Dolby B noise reduction need to have this switch in the Dolby B
position, tapes to be recorded with Dolby C noise reduction n e e d
to have this switch in the Dolby C position, and tapes to be recorded
without Dolby Noise Reduction need to have this switch set to the OFF
position).
3.
Set the reverse mode switch to the desired position.
4.
Set the
AUTO LEVEL
switch to the desired position.
5.
Press the
REC
button. The REC indicator will begin to flash indicating

Erasure Of Tape
When a program source is recorded onto a tape, the previously re-
corded sound is erased automatically, and replaced with the new
recording. If you wish to erase a tape without recording, set the
RECORD LEVEL
control to the minimum (0) position and record.
Set the
AUTO LEVEL
off.
To Protect Valuable Recordings
In the record mode, information previously recorded on the tape will
automatically be erased. To prevent this from happening, use a small
screwdriver to break out one or both safety tabs (See Figure 2 on pg. 17).
It is possible to restore the recording capability of either side of the
cassette by covering the opening with clear adhesive tape (See Figure
4 on pg. 17).
Auto Tape Selector
This unit is equipped with an auto tape selector which automatically sets
the bias and equalizer level using the detection holes provided in the
cassette shell. The bias and equalizer levels are automatically set
according to the type of cassette as follows. (See Figure 3 on pg. 17)
