-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.

CARDIOID

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