Tips on how to use the phase reverse

By pressing the REVERSE button, you invert the microphone's polarity. When the REVERSE button is released (status LED off ) the signal is in phase. Pressing it switches the signal out-of-phase (LED on).

Reasons for reversing the phase:

1.You are recording a vocal or voice-over and the vocalist cannot hear him or herself very well in the headphones. Reversing the phase effectively reverses the polarity between microphone and monitor signal, thus enabling the vocalist to hear him or herself better without any volume increase in the headphones.

2.The REVERSE button is engaged to adjust the GoldMike to the polarity of a microphone or microphone wiring scheme. GoldMike's XLR connectors are configured as follows: pin 2 = high (+), pin 3 = low (-).

3.Experimenting with the phase reverse option may reward you with better results.

The PAD switch attenuates the input signal by 30 dB, allowing even high-level signals to be processed by the GoldMike.This may apply to loud drum or brass recordings.

The HIGHPASS filter will pass only frequencies above a certain threshold, thereby eliminating unwanted portions of a signal. The GoldMike's roll-off point is set to 50 Hz. We use a 2nd order Butterworth filter for its low ripple. The roll-off slope is 12 dB per octave.

Applications for the HIGHPASS filter:

1.Voice-over recordings suffering from the "proximity effect", a boost in low frequencies due to the short distance between sound source and microphone.

2."Pop" sounds that extend into the lower frequency range.

3.Any unwanted signal, such as steps, rumble and other low-fre- quency sounds.
