Fostex 350 - REAR PANEL INPUTS; REAR PANEL OUTPUTS AND CONNECTORS

from A is applied to the left monitor channel and B to the
right. Pressing A or B only, the respective signal is applied to
both left and right monitor channels. (The acoustic image of
the signal will appear centered between the two monitor
speakers or headphones).
Push buttons for groups C and D provide the same function
as above. The left channel and right channel signals of the
Aux buss can be applied to the monitor circuit by depressing
the fifth button.
14. HEADPHONE LEVEL CONTROL
A stereo level control which controls the level of the monitor
signal as selected by the pushbuttons above.
15. HEADPHONE JACKS.
Two stereo jacks wired in parallel for two stereo headphone
sets. Note: Do not use a mono single pole type plug in these
jacks as this will short-circuit one of the outputs and will re¬
sult in distortion, and may cause damage to the internal cir¬
cuits.
16. POWER SWITCH.
Depressing this switch applies AC power to the model 350
and cause the red LED to glow.
When the optional meter bridge is installed on this mixer, the
meters will illuminate when power is switched on.
REAR PANEL
All inputs and outputs (except headphone) are available on
the rear panel. The panel divides logically into inputs, outputs
and monitoring.
17. INPUT JACK.
The channel input jack which matches levels from -60dBV
(ImV) through - lOdBV (0.3V). Input impedance is approx¬
imately 50kOhm.
18. TAPE IN JACK.
Input pin jack connector for receiving the outputs of a
multitrack recorder. It can also be used to receive outputs
from an echo device, reverb unit or other line source.
19. ACCESSORY SEND/RECEIVE.
This is the “patch point” between the preamplifier output and
the input fader (refer to block diagram) where an external pro¬
cessor such as an equalizer may be plugged in.
20. DIRECT OUT.
Output signal after input fader and equalizer. No separate
level control is provided, however, this multi-purpose output
can be used with a submixer (or alone) as the signal for an ef¬
fects unit, or the direct input to a multitrack machine, etc.
21. 4 CHANNEL BUSS IN.
Input connectors for accepting the output of an external ef¬
fects unit, or echo receive. This level is controlled by the four
buss in level controls above the master faders.
22. 4 CHANNEL BUSS OUT.
The four channel buss outputs for feeding a multitrack
recorder, P.A., etc.
23. AUX BUSS IN (left and right).
Input jacks for mixing the outputs from an external signal
processor, or aux receive. No level control is provided for
this input.
24. AUX BUSS OUT.
Stereo output to feed the monitor amplifier or echo unit etc.
25. MONITOR OUTPUT.
Signal from the monitor selector pushbuttons, normally con¬
nected to cue and monitor amplifiers.
26. PHONO INPUT/OUTPUT.
Two stereo phono pre-amplifier, which are completely in¬
dependent of the mixer circuits.
Connect the magnetic cartridges directly to the inputs. Cor¬
responding output connection to the mixer may be made to
any channel using a phono/phono or phono/phone patch cord
to any of the input channels: to the input jack, accessory
receive or tape input.
27. METER BRIDGE CONNECTOR.
This is a multipin connector reserved for connection to the
optional meter bridge.
28. POWER CORD.
Connect to AC supply as indicated.
NOTE:Please ensure that your AC supply voltage is
as indicated on the rear of the Model 350 mixer.
