Controls
This +48 V switch activates the +48 V phantom power
(1)
(EN)
circuit that uses the signal leads to supply condenser
microphones with the required operating voltage.
Use the MIC/LINE switch to toggle between
(2)
MIC and LINE modes. When the switch is pressed,
the unit works in MIC mode (now you can press the
+48 V switch if required; in LINE mode this function
is disabled).
The MIC GAIN control is enabled in MIC mode only and
(3)
allows for applying gain from 10 to 60 dB to the input
signal. In view of the extremely high gain levels that
can be applied, you should verify that the gain control
is properly set before you power up the unit. In case of
doubt, set the control fully counter-clockwise, and start
from there slowly raising the gain. High gain settings
and the resulting levels can damage subsequent devices.
The CLIP LED signals that a level of at least +18 dBu is
(4)
present after the microphone amp stage. With too high
a level the CLIP LED warns you to reduce the gain with
the MIC GAIN control, so as to avoid distortion caused by
overloading. During normal operation, the LED should
not light up at all.
With the PHASE REV. switch the input signal is reversed
(5)
in phase by 180°. This function is available both in MIC
and LINE modes.
When the high-pass filter is switched on (LO CUT switch
(6)
pressed), the FREQUENCY control defines the filter's
cut-off frequency. With a setting range from 12 to 320 Hz
the filter's main task is to eliminate bottom-end rumble
noise, etc.
The LO CUT switch activates/deactivates the
(7)
high-pass filter.
The FREQUENCY control is used to select the frequency
(8)
to be modified. Please note that the frequency range can
be lowered/raised with the switches x0.1 and x10. In this
way, you can process the entire audio range between 10
Hz and 20 kHz. With both switches out, the FREQUENCY
control can be swept over a range from 100 Hz to 2 kHz.
The x 0.1 switch lowers the working range of the
(9)
FREQUENCY control to 10 - 200 Hz, so that you can
process the bass end of the audio spectrum.
The x 10 switch raises the working range of the
(10)
FREQUENCY control to 1 - 20 kHz, so that you can process
the treble end of the audio spectrum.
The BANDWIDTH control determines the slope or quality
(11)
of the filter. Bandwidth ranges from 0.03 (Q = 43) to 2
octaves (Q = 0,67).

Quick Start Guide
With the LEVEL control you can set the amount of level
(12)
reduction/gain applied to the filter. The setting range is
from -15 to +15 dB.
The EQ IN/OUT switch activates/deactivates the
(13)
parametric EQ. Please switch the EQ off unless you need
it for your specific audio application.
The OUTPUT control raises/lowers the output level
(14)
of the device by a maximum of 20 dB (+/- 20 dB).
With the control in mid-travel position, no level change
is applied. Available both in MIC and LINE modes.
The OUTPUT LEVEL LED chain displays the output
(15)
level within a range from -30 to +18 dB. The display
is referenced to a level of +4 dBu.
MAINS CONNECTION. Use the enclosed power cord
(16)
to connect the unit to the mains. Please also note the
instructions given in the "Installation" chapter.
AUDIO IN. These are the audio inputs of your ULTRAGAIN
(17)
PRO. The XLR connector is the common mic/line input.
The line input is based on jack connection.
AUDIO OUT. These are the audio outputs of your
(18)
ULTRAGAIN PRO. Matching phone jack and XLR
connectors are wired in parallel.
