Using the PAD Switch

The C03U includes a PAD switch, which you can 

use to lower the input sensitivity of the micro-

phone. When the PAD switch is set at the 0dB posi-

tion the PAD is bypassed and there is no effect on 

the signal. When the PAD switch is set to the –10dB 

position, the microphone’s input sensitivity will be 

lowered by 10dB.  You can use the PAD when you 

are miking  loud sound sources with a high SPL 

(Sound Pressure Level). 

Using the Hi-Pass Filter

The C03U offers a user selectable hi-pass, or low-cut filter, which you can use to elimi-

nate any unwanted low frequency reproduction. When the Hi-pass Filter is is set to 

the “flat” (indicated by the straight line) position, 

there is no effect on the signal. When the Hi-pass 

switch is set to the “roll-off” position (indicated 

with the angled line), a 12dB per octave low-cut 

at 100Hz is applied to the signal. This can be 

extremely useful for removing low frequency stage 

rumble, wind noise during outdoor use, and filter-

ing out lows from drums when used as overhead 

cymbal microphone on a drum kit.

Polar Patterns

The most important characteristic of any microphone is its directionality or “pickup 

pattern”. The C03U’s versatile dual capsule design is capable of producing three useful 

pick up patterns; Cardioid, Omni, and Figure 8.  It is easy for you to select the pickup 

pattern using the C03U’s pattern selection switch located on the rear of the micro-

phone. When choosing a pattern, you should be aware of the phenomenon known as 

the “proximity effect”. 

Simply put, proximity effect is the change in frequency response as the microphone 

position is changed relative to the sound source. Any microphone exhibits its best 

frequency response when pointed directly at the sound source (on-axis). Depending 

on the pickup pattern, the low frequency response will increase, sometimes 

greatly, when positioned less than 12 inches away from the sound source (off-axis).  

Understanding and knowing how to use the proximity effect can be a tremendous 

help in getting just sound you looking for. The following sections details the three 

available pickup patterns.
