ADX20i/ADX20iP

ADX20iP

OVERVIEW

Designed, assembled and tested by Audix in the USA, the ADX20i is a miniaturized

condenser microphone used for professional stage and studio applications. The

ADX20i is known for its clarity, excellent transient response, resistance to feedback,

SPL handling and ease of operation. The ADX20i is primarily used for miking

saxophone and other brass instruments.

The ADX20i is characterized with a uniformly controlled cardioid polar pattern. This

provides excellent isolation and feedback control on stage as well as natural sound

reproduction at very close distances.

With a smooth and accurate response over a frequency range of 40 Hz - 20 kHz, the

ADX20i is lightweight, compact and simple to use. Housed in an aluminum ring and

isolated by means of a rubber shock mount system, the ADX20i comes with a spring

tension gooseneck clip (MC20i) for easy mounting to the bell of an instrument. A

number of optional accessories are available, which allows for the ADX20i to be used

on a microphone stand for a wider variety of applications.

The ADX20i is designed for use with Audix wireless systems. The ADX20iP is designed

for use with a standard microphone cable. The ADX20iP operates on phantom

voltage of 5-52 Volts and is supplied with a phantom power adapter (APS910), 6’

integrated microphone cable, gooseneck clip (MC20i) and carrying pouch.

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
“mic 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 mic 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 mic 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 mic 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

Hi

hypercardioid capsule may be more helpful. The ADX20iP can be used on a mic
stand or mic bar for stereo recording (see accessories for mic stand adapters).

Live sound: In general, when using multiple mics on a stage for live sound,
position the mics at least 2-3 feet apart from each other to avoid phase
cancellation issues.
