Frequency selector for the AIR BAND.
The shelf peaks are set at 2.5kHz,
5kHz, 10kHz, 15kHz, 20kHz, and
40kHz.
FUNCTIONS & TECH SPECS
AIR GAIN
Gain control for the AIR BAND.
GAIN
Continuously variable GAIN knob
control for the preamp.
SIGNAL
Green LED indicates audio
signal presence.
AIR BAND
®
Engages the AIR BAND.
+25 GAIN
Increases the GAIN to
a range of 42-71 dB.
-20 PAD
Attenuates the mic signal
(pre transformer)
by –20 dB.
48v PHANTOM POWER
Supplies Phantom Power to mic.
HIGH PASS FILTER
Knee starts @ 160 Hz and is
–3 dB @ 70 Hz.
PHASE REVERSE
Reverses the phase of the output
relative to
the input.
INSTRUMENT / MICROPHONE THRU
¼-inch unbalanced, isolated and
boosted of a low impedance mic or
the Instrument inputs.
PEAK
Red LED starts to illuminate when
the output signal reaches 23 dBu.
INSTRUMENT INPUT
¼-inch (1-meg-ohm)
Instrument Input jack
• Max Gain 71dB
• Noise level at the lowest gain setting is
-100dB. EIN is -128dB
• Balanced XLR output headroom is +25dBu
• The microphone transformer feeds a differential
set of front-end Class A discrete transistors paired
with a FET input operational amplifier.
• High and low gain push button switch. Low range:
+20dB to +42dB. High range (gain +25 switch with
green LED): +42dB to +71dB. Switchable -20dB pad
• +48-volt phantom power, switchable, with red LED.
Phase reversal switch: switches the phase of the
balanced output.
• Green signal present LED, red peak LED lights
at +25dBu.
