MIC GAIN A 12-way precision rotary switch covering from 0 to 66 dB in 6 dB steps.
Selecting the right gain optimizes Noise and Headroom.
TRIM Provides further gain adjustment, continuously over a range of +/– 6 dB.
+48V Push button makes phantom power available at the microphone input.
Ø Push button inverts the phase of the signal path.
MUTE Disconnects the main output.
SILK Much could be written about this feature, but suffice to say that it gives a subtle
option to enhance sound quality in the direction of vintage modules. The SILK
button reduces negative feedback and adjusts the frequency spectrum to
provide a very sweet and musical performance. We suggest you try it and make
your own judgment.
TO BUSS Provides a resistive feed to the Portico™ Buss mix system.
HPF A 12 dB/octave high pass filter providing continuously variable Low Frequency
attenuation between 20 Hz and 250 Hz. The high pass filter is a valuable aid in
any signal chain but particularly so in a microphone preamplifier. Signals
within this band can be attenuated, leaving higher frequencies unaffected.
Helps get rid of building rumble, air handling motor hum etc. (see fig. 1)
