SOURCE
This switch allows you to select between the MIC and HI-Z/LINE inputs. Both inputs can remain connected at all times, regard- less of which input is selected.
When first thrown after powering up the unit, this switch can cause a noticeable pop due to the discharge of residual current. This is normal and no cause for concern.
HI PASS
This switch activates the integrated high-pass filter, which oper- ates at a 50-Hz center frequency and 12 dB/octave (often called a „rumble filter“). The filter is entirely passive, avoiding addi- tional active circuitry that could potentially degrade the signal, and cuts 6 dB pre- and 6 dB post-solid-state preamplification to prevent the amplification of unwanted low-frequency signal portions.
PHASE
The phase reverse function reverses the polarity of the micro- phone signal, „turning“ the phase by 180° to correct phase- inverted signals caused by multiple signal sources.
A voice-over artist, for example, hears himself during recording through the headphones and simultaneously through the bones in his head. Phase inversion will cause an unnatural sound and even minimal variations in distance to the microphone will cause drastic variations in the sound. Phase inversion is also commonly encountered when using multiple microphones on a single sound source.
The GainStation 1‘s phase reverse switching is achieved passively via a relay, pre-preamplification, to avoid additional active circuitry.
