-10 dB PAD SWITCH, REF-CARDIOID & REF-GOLD
This tiny switch near the base of the microphone
body reduces the signal by 10 dB. Rather than
changing the capsule voltage or adding a resistor
into the signal path we chose a better technique.
We change the amount of negative feedback
derived from a dedicated transformer winding.
While the tube circuit will handle any signal the capsule can deliver, the pad may be
needed with some pre-amps. If you suspect that the mic is distorting, first try a different
mic pre. The capsule is rated for 150 dB SPL but wind or air movement are exceptions. A
pop filter will be needed for close vocals.
LOW PASS FILTER SWITCH, REF SILVER
This switch activates a filter which is useful if trying to remove
unwanted low frequency noise from a room such as rumbling
from traffic etc. Switching to this position activates the -3dB
55 Hz filter. Switching to is back to a flat frequency response.
PATTERN SELECT CONTROL, REF-GOLD
This control provides the user with a choice of
any typical polar pattern. Many high quality
condenser microphones give the user 3 or 4
patterns only; The Gold Mic provides you with
an infinite number of patterns via this control.

FIGURE 8
CARDIOID
For example, a setting between the “heart shaped” CARDIOID and FIGURE
8 will result in “SUPER-CARDIOID” and “HYPER-CARDIOID” patterns.
