OPERATING CONTROLS
GAIN SWITCH:
12-position gain control employs a superior quality Grayhill
mil-spec gold plated rotary switch. Switch gain is approximately 5 dB per
step. After a brief warm-up period adjustment of this switch is virtually
silent.
OUTPUT CONTROL:
When the Output Control knob is fully clockwise, the
output gain is at unity; when the Output Control knob is in the mid-position,
the output is 20dB down. Keep output gain at max for optimal
performance.
PAD SWITCH:
provides 10 db of pad at input.
VINTAGE / MODERN SWITCH: selects the preamp circuit to be used.
NORMAL / COMBO SWITCH:
selects routing of preamp circuits. With
VINTAGE and COMBO selected, preamp circuit is vintage and output circuit is
modern. With MODERN and COMBO selected, modern circuit is preamp and
vintage circuit is output. In NORMAL mode the circuits are not combined.
INPUT SWITCH: selects rear panel mic input or front panel instrument
input.
PHASE SWITCH: gives 180° phase change at balanced output.
PHANTOM POWER SWITCH (“+48V”): provides phantom power
(+48VDC) to the microphone inserted into that channel. When this switch is
depressed (illuminated red), phantom power is applied simultaneously
through dual 6.81k ohm resistors to pins 2 and 3 of the three pin female XLR
input. Use phantom power with condenser and other microphones requiring
traditional phantom supply. CAUTION: Applying phantom power to ribbon
microphones could damage them. Do not use phantom with ribbons, moving
coil, and other microphones which do not require phantom power. Use care,
as well, to not insert or extract mic cables from the FOX when phantom
power is active.
SIGNAL INDICATOR LED: The green "signal present" LED indicates that
signal is present at the microphone or instrument input. The intensity will
vary with increases or decreases in signal level.
POWER SWITCH:
When illuminated the LED in power switch shows that
the FOX is powered and active.
