Audix ADX51 Cardioid Condenser Instrument Microphone

The ADX51 is a pre-polarized condenser microphone designed to handle a wide variety of live, studio and broadcast applications. Characterized with a cardioid pickup pattern and a smooth uniform response over a frequency range of 40-20k Hz, the ADX51 is precision machined from solid brass with a low reflective black e-coat finish.

The ADX51 is designed with low noise electronic circuitry, balanced output, and switches that enable a 10 dB pad and a bass roll-off. The ADX51 is road-worthy and capable of handling high sound pressure levels of 142dB.

Applications

• Overhead for Drums / Percussion
  Bells, cymbals, hi-hat, goodie table
• Acoustic instruments
  Guitar, piano, saxophone, orchestra (zone miking)
• Group vocals
  ADX51 may be used as a hanging mic or on a stand to pick up group vocals for ensemble, choirs or plays. Two mics may be positioned overhead or in front of the group, at a distance of 4-6 feet apart.

Operation and Maintenance:
Condenser microphones as a general rule are much more sensitive and reactive than dynamic microphones and should be handled with care. Avoid extreme temperatures wherever possible. Moisture and high humidity can adversely effect the performance of the microphone and cause permanent damage. For outdoor use, consider using the foam windscreen (WS-ADX51) to reduce wind noise or popping. When not in use, please store your

Recording:
The ADX51 can be used effectively to record just about any acoustic instrument. Because of the simple design and excellent transient response, simply point the microphone towards the sound source making sure the mic is far enough away to avoid distortion.

Live Sound:
When miking instruments, the ADX51 should generally not be closer than 6 inches to the sound source. In the case of group vocals, drum overheads, bells, and percussion toys, the microphone can be from 1-4 feet from the source. In general, when using multiple ADX51s for live sound, they should be spaced at a distance of at least 4-6 feet apart. Using fewer mics can result in a more ‘spatial’ effect and provides greater chance for greater control over feedback.

Pad and Roll-Off:
These recessed switches are located towards the bottom of the mic. You will need a either a miniature screw driver or a pen to move them down (engaged) or up (not engaged).

Pad:
The switch on the lower left side of the mic is a 10 dB pad. This means you can reduce the input level of the mic by 10 dB. This is very helpful for miking extremely loud instruments (guitars, drums, horns) that may tend to drive the mic into distortion. Note that 0 dB is in the up position and -10 dB is in the down position.

Bass Roll-Off:
This feature gently rolls off the bass frequencies starting at 150 Hz which is very helpful in reducing boominess for voice or instrument. Note that the feature is active when the switch is in the down position.

OUTPUT:
It is recommended to use a high quality microphone cable with 3 pin XLR connectors. The ADX51 output is balanced across Pin 2 (positive) with respect to Pin 3, with the shield connection is Pin 1.
