Phase
The phase reverse function reverses the polarity of the micro-
phone signal, inverting 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. We recommend checking for correct
polarity before each recording.
Pad
The Pad switch attenuates the input by -20dB. High-level input
signals can be attenuated in order to prevent overdriving the
preamplifier. The GoldMike MK2 has a minimum pre-amplifica-
tion of +14 dB. But with miked signals such as drums and brass
or high level line input signals, this may already be too much.
Engaging Pad attenuates the minimum pre-amplification (Gain
control fully counter clockwise) to -6 dB, thus providing a useful
Gain control range for loud input signals.
Hi Pass
This switch activates the integrated high-pass filter, which
operates at a 50 Hz center frequency and 12 dB/octave (often
called a „rumble filter“). The filter is entirely passive, avoiding
additional active circuitry that could potentially degrade the
signal, and cuts 6 dB pre- and 6 dB post-solid-state stage pre-
amplification to prevent the amplification of unwanted low-
frequency signal components.
