ULTRAGAIN PRO MIC2200 Controls
Controls
1. This +48 V switch activates the +48 V phantom power circuit that uses the signal leads to supply condenser
microphones with the required operating voltage.
2. Use the MIC/LINE switch to toggle between 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).
3. The MIC GAIN control is enabled in MIC mode only and 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.
4. The CLIP LED signals that a level of at least +18 dBu is 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.
5. With the PHASE REV. switch the input signal is reversed in phase by 180°. This function is available both in
MIC and LINE modes.
6. When the high-pass filter is switched on (LO CUT switch 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.
7. The LO CUT switch activates/deactivates the high-pass filter.
8. The FREQUENCY control is used to select the frequency 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.
9. The x 0.1 switch lowers the working range of the FREQUENCY control to 10 – 200 Hz so that you can process
the bass end of the audio spectrum.
10. The x 10 switch raises the working range of the FREQUENCY control to 1 – 20 kHz so that you can process the
treble end of the audio spectrum.
11. The BANDWIDTH control determines the slope or quality of the filter. Bandwidth ranges from 0.03 (Q = 43) to 2
octaves (Q = 0,67).
12. With the LEVEL control, you can set the amount of level reduction/gain applied to the filter. The setting range is
from -15 to +15 dB.
13. The EQ IN/OUT switch activates/deactivates the parametric EQ. Please switch the EQ off unless you need it for
your specific audio application.
14. The OUTPUT control raises/lowers the output level of the device by a maximum of 20 dB (+/- 20 dB).
With the control in the mid-travel position, no level change is applied. Available both in MIC and LINE modes.
15. The OUTPUT LEVEL LED chain displays the output level within a range from -30 to +18 dB. The display
is referenced to a level of +4 dBu.
