Meters 1 through 4 monitor record and.
playback levels on their respective
tracks when the METER selector is set
to RECORDER position. However, the
four meters monitor the 4 CHAN BUSS
OUT's when the METER selector is set
to MIXER position.
The 1 and 2 meters can also monitor
the LEFT and RIGHT of LINE OUT
levels, respectively, depending on the
setting of the METER function switch
[ 10 ].
10. METER FUNCTION SWITCH
(RECORDER-MIXER)
All four meters will monitor the signals
determined by the METER selector
switch, as explained below:
RECORDER: Indicates recorder’s out¬
put levels as follows: the
Record input of those
channels in the record
mode, and the tape output
of those channels in the
play mode.
MIXER: Indicates 4 CHAN BUSS
OUT levels from the mixer
section. Although all four
channel buss outputs are
applied to the recorder,
channels 1 and 2 are also
fed to the rear panel LINE
OUT 1, 2 jacks, and there¬
fore meters 1 and 2 also
monitor the LINE OUT’s.
Aux Receive 1 -2 and Headphone
Level
11. AUXILIARY RECEIVE LEVEL
CONTROL (RCV 1-2)
This control simultaneously adjusts the
level from both the LEFT and RIGHT
AUX IN Jacks [28]. The signals are then
applied to BUSS CHAN 1 and BUSS
CHAN 2 of the 4 CHAN BUSS, ahead of
the MASTER 1-2 fader (13). When AUX
IN is used for effects return, this control
adjusts the proportion of effect (e.g.,
reverb or echo) to “dry” signal. When
AUX IN is used as a sub input from
another mixer or remote feed, the RCV
1 -2 control serves as a sub master for
the remote mix. If possible, it is recom¬
mended that RCV 1 -2 initially be set at
# 7 and the output level from the effects
unit or other mixer be set for proper
balance and low distortion; if it is not
practical to adjust the incoming level,
set RCV 1-2 as required.
12. HEADPHONE LEVEL
The headphones are OFF when the knob
is at center (12 o’clock): CCW rotation of
the control allows monitoring of the
MONMIX signal in the left and right
headphones at equal levels.
The 4 CHAN BUSS signals can be
monitored in stereo by rotating the con¬
trol clockwise. (Mixed signals of buss 1
and 3 are heard in the left headphone,
and buss 2 and 4 in the right headphone.)
13. MASTER 1-2 FADER
This MASTER FADER simultaneously
controls the levels of both BUSS OUT 1
& 2 of the 4 CHAN BUSS. This FADER
affects the following circuits:
a) the LINE OUT 1 jack [29],
b) the LINE OUT 2 Jack [29],
c) the 1 and 2 meters [9] when the
METER selector [10] is set to MIXER
position.
Tape Transport Features
14. RECORD TRACK SELECTOR
BUTTONS (1-4) AND INDICATORS
These four push buttons and LEDs are
numbered to correspond wilh the four
tracks on the cassette tape. When a
button is depressed, its track is “record
ready,” as indicated by a blinking LED
above the RECORD TRACK button.
Recording will not actually begin until
either:
a) the RECORD button [16] and PLAY
button [18] are simultaneously press¬
ed, or
b) the PLAY button [18] is pressed and
then the REMOTE FOOT SWITCH
(PUNCH-IN/PUNCH-OUT) is actu¬
ated.
There is one exception,-when depress¬
ing a RECORD TRACK selector button
immediately results in recording: when
the RECORD and PLAY buttons have
already been pressed so that the trans¬
port is rolling tape (and the red LED left
of the RECORD button is blinking, then
depressing a RECORD TRACK Selector
switch will cause the track to enter
record mode.
The LEDs show the status of the
associated tape tracks as follows:
UNLIT: Track is in “safe” mode and
will not record even if
RECORD and PLAY buttons
are pressed.
BLINKING: Track is in "record ready”
mode, and will record as
soon as the RECORD and
PLAY buttons are pressed
(or PLAY and then REMOTE
PUNCH-IN).
STAYS ON: Track is recording.
15. TAPE INDEX COUNTER ANO
RESET BUTTON
A 4 digit display accurately indicates
relative tape position (by means of a
photo-interrupter circuit on the trans¬
port takeup spindle). Pressing the ad¬
jacent RESET button sets the display at
0000. To take advantage of the ZERO
RETURN function [21], it is recommend¬
ed that the RESET button be pressed
at the beginning of a “take,” especially
when overdubbing or making inserts.
16. R ECORD BUTTON AND INDICATOR
The effect of pressing the RECORD but¬
ton will vary, depending upon the status
of certain other controls. The adjacent
LED helps to signal the status, as ex¬
plained below:
(a) If you press RECORD while tape is
stopped:
The RECORD MODE LED adjacent
to the RECORD button blinks. Should
any of the four RECORD TRACK
selector buttons [14] be depressed,
TAPE OUT and MONMIX from that
channel automatically change from
the reproduce amplifier to the record
input signal. Then as soon as either
the PLAY or STOP button is de¬
pressed the LED turns off, and the
SYNC signal returns to the repro¬
duce amplifier.
(b) If you press RECORD and PLAY at
the same time:
If none of the four RECORD TRACK
selector buttons [14] is depressed,
the RECORD MODE LED adjacent to
the RECORD button blinks, and tape
is transported in play mode. The unit
is “record ready,” however, and
should any RECORD TRACK selector
button be depressed, its track will
immediately enter record mode.
If one or more RECORD TRACK se¬
lector buttons is already depressed
when the RECORD and PLAY buttons
are pressed, the corresponding track
(or tracks) will enter record mode.
The RECORD MODE LED next to
the RECORD button will be illumi¬
nated, as will be the RECORD
TRACK LED for any track that is
recording.
