POLAR PATTERNS

ARCHITECT AND ENGINEER SPECIFICATIONS

The microphone shall be of the condenser type with a modular threaded  
capsule. The microphone shall be available in a hypercardioid polar pattern 
and shall have a 6’ cable terminating in a mini-XLR female connector. The  
microphone shall have a sensitivity of 6 mV / Pa and a nominal impedance of 
250 ohms at 1 kHz. The microphone shall have a maximum SPL level of 135 dB 
at 0.5% THD and shall be machined out of brass with a length of 30 mm and a 
capsule diameter of 12 mm. 

OPERATION AND MAINTENANCE 

The ADX20i is designed to plug directly into the bodypack of a wireless system. 
For wired applications see the ADX20iP.

The ADX20iP is a low impedance microphone and should be plugged into a 
“microphone level” input on your console, mixer, or recording device. The 
ADX20iP requires phantom power and will NOT operate without phantom 
power voltage (minimum of 5 - 52 Volts) which is available on most professional 
microphone preamps and mixing devices. If phantom power is not available on 
your equipment, you may use the APS910. Avoid plugging or unplugging the 
microphone from a PA system unless the channel is muted or the volume of 
the system is turned down. Failure to do so may result in a loud “popping” noise 
which could seriously damage the speakers in the PA system. 

APS910 phantom power supply:

 Note that the mini XLRf connector at the 

end of the ADX20i microphone cable plugs into mini XLRm side of the APS910 
phantom power adapter. From there, plug a standard XLR-XLR microphone 
cable to complete the connection from the APS910 to the mixing board.

Important:

 Be sure that the round ports on the microphone capsule always 

remain exposed and do not get covered up in any way by the shockmount in 
the clip.

The ADX20i is manufactured to exacting specs with roadworthy construction. 
However, the capsule is highly sensitive and should be handled with care. Avoid 
extreme temperatures and be sure to store your microphone in the pouch 
provided when not in use. Moisture of any kind can adversely effect the sound 
and performance of your microphone.

USER TIPS 

Saxophone and brass:

 For the most accurate and natural sound the microphone 

should be positioned towards, but not inside, the bell. Some experimentation may 
be required to find the proper blend between the instrument and the room. 

When striving for greater isolation on stage and higher gain before feedback, 
the hypercardioid capsule may be more helpful. The ADX20iP can be used on a 
microphone stand or microphone bar for stereo recording (see accessories for 
microphone stand adapters). 

Live sound:

 In general, when using multiple microphones on a stage for live 

sound, position the microphones at least 2-3 feet apart from each other to avoid 
phase cancellation issues.
