40. GROUP OUT JACKS (GROUP OUT 1, 2, 3, 4)
Output jacks of the GROUP buss 1 ~ 4 which are
normally used for sends to the multitrack recorder.
41. GROUP IN JACKS (GROUP IN 1, 2, 3, 4)
Input jacks of the GROUP buss 1 ~ 4. Normally,
effects returns and outputs of other mixers are
plugged in here and used for mixing into the GROUP
buss.
42. 2 TRACK IN JACKS (2 TRK IN 1 ~ 2)
Master recorder outputs are normally connected here.
Playback of the master tape can be simply monitored
by selecting the 2 TRK IN SOLO button 1 ~ 2 (25).
43. STEREO OUT JACK (STEREO OUT 1 ~ 2)
Output jacks of the STEREO buss. These are normally
used for sends to the master recorder. Although
signals via the STEREO master fader (22) will be sent
both to 1 (RCA pin jacks) and 2 (stereo phone jacks),
their rated output levels will be -lOdBV at 1 (RCA
pin jacks) and + 2dBV (+ 4dBs) at 2 (stereo phone
jacks), and either level can be chosen for your
particular application.
The polarity of 2 (stereo phone) is L for the TIP and
R for the RING.
44. STEREO IN JACK (STEREO IN)
Input jacks of the STEREO buss. These jacks are
used to connect the stereo outputs of another mixer
or effects returns for mixing into the STEREO buss.
45. MONITOR OUT JACKS (MON OUT 1 - 2)
The signal selected by the MONITOR selector (26)
is output here via the MONITOR level knob (28). If
at least one PFL button (15) or SOLO button is
pressed, the PFL buss output signal (the signal
passing through the PFL/SOLO level knob (30)) will
be the output here via the MONITOR level knob (28).
SECTION 3.
CONNECTIONS WITH
1. IMPEDANCE
Input and output impedances should always be
considered when connecting this unit to other
equipment.
Impedance is the resistance value against alternating
currents such as sound signals and the unit of
measurement is Q (Ohm). If the output impedance of
a given unit does not match the input impedance of
the other, sound distortion or even equipment
breakdown could occur. In general, the rule is that
output impedance should be low (low out) and input
impedance should be high (high receive). Refer to
SPECIFICATIONS in page 19 for input/output impe¬
dance of this unit.
NOTE:
Always use a Direct Box when interconnec¬
ting outputs indicated in watts, (W) such as that of
a power amplifier, with a high impedance input. If this
precaution is not followed, severe damage may result.
In this function, only one of either 1 (RCA pin jack)
or 2 (stereo phone jack) will be effective (Refer to
MONITOR OUT selector (27)).
The polarity of 2 (stereo phone) is L for the TIP and
R for the RING.
46. CUE OUT JACK (CUE OUT)
The output jacks of the CUE buss. The mixed signal
of the SUB MIX sections (3), (4) can be this output
via the CUE master level knob (31). This mix is a
convenient monitor/cue for the musicians.
47. HEADPHONE JACK (PHONES)
The same source at MONITOR OUT jacks 1 - 2 is
the output here.
48. PREFADER LISTENfSOLO INDICATING LED
(PFL/SOLO)
This will be lit when at least one of the PFL button
(15), SOLO buttons (16), (19), (24), or (25) is
pressed. While this LED is lit, the PFL buss output
signal will be sent to the MONITOR OUT jacks 1 ~
2 (45) and the PHONES jack (47), and the mixed
signal of the PFL buss will be indicated on the L, R
sections of the meter (32).
49. POWER LED (POWER)
This is lit when power is applied to the POWER supply
connector (50).
50. POWER SUPPLY CONNECTOR (POWER)
* NOTE 1: THE TAPE TRIMMER
This trimmer is for matching the input level of this units'
TAPE IN jack (36) with a recorder whose output level is
other than -lOdBV.
Although its variable range is -16dBV ~ + 20dBV, it is
adjusted to -lOdBV at leaving the plant and Fostex
multitrack recorders such as Model E-16, E-8 and 80 can
be connected without any adjusting.
EXTERNAL EQUIPMENT
2. LEVEL MATCHING WITH EXTERNAL
EQUIPMENT
Matching the level of the external equipment connec¬
ted to the INPUT jacks (33) and (34) of this unit is
done by the TRIM (1) controls. Adjust so that the
PEAK LED (6) does not frequently flash on the signal
peaks. As noise and distortion is the least in the range
of 0 ± 5 (dB) of the INPUT faders (17), it is
recommended to preset them within this range, then
adjust the level with TRIM (1). During this operation,
if the PFL button (15) and INPUT SOLO button (16)
are pressed in advance, the prefader and post-fader
levels and tone can be conveniently checked.
However, as the PEAK LED (6) will be lit during
overloading at EQ (7), each gain of EQ (7) should
be kept flat when adjusting TRIM (1). After setting
TRIM (1), if the PEAK LED should be lit during testing
of the tone by EQ (7), there is overloading at the EQ
stage (7) and the corresponding gain should be
decreased, or re-adjust TRIM (1).
