Fostex 450 - Buss and Monitor Output Controls; Input and Output Jacks Overview

L/R can be divided into four groups — channels 1 and 2, 3
and 4, AUX 1 and AUX 2 L/R.
By pressing the 1 and 2 buttons together, the signal from
channel 1 is applied to the left channel of PHONES and
MONITOR OUT, and the signal from channel 2 is applied to
the right channel. Press either 1 or 2, and the signal selected
can be applied to both the left and right channels.
The 3 and 4 group functions in the same way as group 1 and 2.
When the AUX 1 button is depressed, the AUX 1 signal is
applied to both PHONES and MONITOR OUT.
The group function of the AUX 2 button is the same as for BUSS
1 and 2 or BUSS 3 and 4.
When the four button groups (BUSS 1 and 2, BUSS 3 and 4,
AUX 1, and AUX 2) are simultaneously depressed, these
signals will be mixed and applied to PHONES and MONITOR
OUT.
17. METER SELECT SWITCH [METER]
Chooses the four LED bargraph meter display for 4-channel
buss out signals or the stereo master outputs.
When set for stereo master out, the two LED bargraph meters
at the right side will not function.
18. SOLO LEVEL CONTROL [SOLO]
This is the knob to control monitor level of the input channel
solo and 4-channel buss out solo signal.
As monitor levels are normally set first (see the following items
19) and 20), solo level is generally set second.
19. MONITOR LEVEL CONTROL [MONITOR]
This pot controls the monitor output level.
20. HEADPHONE LEVEL CONTROL [PHONES]
21. STEREO MASTER OUTPUT LEVEL CONTROL
[STEREO MASTER]
The master level control of the 4-channel buss output signal
mixed down to stereo.
22. 4-CHANNEL BUSS MASTER FADER
23. HEADPHONE JACK [PHONES]
These two jacks are wired in parallel.
24. LED BARGRAPH METERS
These display levels of the 4-channel buss output or stereo
master output.
25. SOLO INDICATOR [SOLO]
This LED is lit when either the input channel solo or 4-channel
buss out solo button is depressed.
26. POWER INDICATOR [POWER]
27. POWER SWITCH [POWER]
28. PHANTOM POWER SWITCH [PHANTOM]
Phantom power supply voltage is 48V DC.
30. TAPE IN JACK [TAPE IN]
Input jacks for receiving (normally) the outputs from a multi¬
track recorder. In addition, these jacks can be used to connect
outputs from reverberation units, compressor/limiters and
other line level sources.
31. ACCESSORY SEND/RECEIVE JACK
[ACC SEND RCV]
This is the patch point, between the preamplifier output and the
input fader, where a signal processor, such as an equalizer, is
plugged in. '
32. PHONE JACK INPUTS [INPUT]
These input jacks are for unbalanced inputs from mic level to
line level: from —60dBV (ImV) through —20dBV (0.1V). Input
impedance is about 50K ohms.
33. XLR JACK INPUTS [INPUT]
These jacks are for balanced mic input signals and will handle
levels of -60dBV (ImV) through —20dBV (0.1V).
Unbalanced signals can also be handled by these XLR jacks:
pins #1 and #2 will be GND; PHANTOM must be switched OFF.
34. 4-CHANNEL BUSS IN [4 CHAN BUSS IN]
Input jacks for mixing the outputs from an external processor
into the 4-channel buss line.
35. 4-CHANNEL BUSS OUT [4 CHAN BUSS OUT]
Normally, these jacks will feed a multitrack recorder.
36. AUX 2 BUSS IN [AUX 2 IN]
Input jacks for mixing the outputs from an external processor
into the AUX 2 buss line.
37. AUX 2 BUSS OUT [AUX 2 OUT]
The AUX 2 buss output jacks are for a monitor amplifier, master
recorder, etc.
38. AUX 1 BUSS IN [AUX 1 IN]
Input jacks for mixing the outputs from an external processor
into the AUX 1 buss line.
39. AUX 1 BUSS OUT [AUX 1 OUT]
The AUX 1 buss output jacks are for signal processors, slap
echo recorders, etc.
40. MONITOR OUTPUT [MON OUT]
The 4-channel buss out, the AUX 1 buss out or the AUX 2 buss
out, as selected by the MONITOR select switch, is active here.
These outputs are generally connected to the cue and monitor
amplifiers.
41. STEREO MASTER OUTPUT [STEREO MASTER]
The 4-channel buss out after mixdown to stereo is the output
here, and it is generally applied to the 2-channel master
recorder.
42. AC POWER CORD
29. D IRECT OUT JACK [D. OUT]
This output stage is immediately after the input fader and
parametric equalizer.
