PRO 70

Cardioid Condenser Lavalier Microphone

Features

• Clip-on lavalier mic provides articulate, full-sounding voice pickup

• Also excels as an instrument mic, especially for pickup of acoustic

guitar with included AT8444 instrument adapter

• Cardioid polar pattern reduces pickup of sounds from the sides

and rear, improving isolation of desired sound source

• Offers the convenience of battery or phantom power operation

• Rugged design and construction for reliable performance

• Switchable 80 Hz high-pass lter minimizes pickup of undesired

low-frequency sounds

Description

The PRO 70 is a miniature clip-on/lavalier condenser microphone with

a cardioid polar pattern. It is designed for quality sound reinforcement,

professional recording, television and other demanding sound pickup

applications.

The microphone is intended to be worn on the clothing or used as an

instrument mic for excellent yet unobtrusive sound pickup. The wide-

range capability of the microphone ensures clean, accurate reproduction

with high intelligibility for speakers and presenters as well as for

instrument pickup. Its small size makes it ideal for use in applications

where minimum visibility is required.

The microphone requires 11V to 52V phantom power or a 1.5V AA battery

for operation. A battery need not be in place for phantom power operation.

The microphone’s cardioid polar pattern provides a 120° angle of

acceptance.

The microphone includes a 1.8 m (6') permanently attached miniature

cable. Its free end connects to the provided AT8531 power module via a

TA3F-type connector. The output of the power module is a 3-pin XLRM-

type connector.

A 3-position switch in the power module permits choice of off, on/at

response or on/low-roll-off (via integral 80 Hz high-pass lter). The roll-off

position reduces the pickup of low-frequency ambient noise.

The microphone comes equipped with a power module, a clothing clip, an

instrument adapter, a windscreen, a battery and a soft protective pouch.

Operation and Maintenance

The PRO 70 requires 11V to 52V phantom power or a 1.5V AA battery for

operation. A battery need not be in place for phantom power operation.

To install the battery, remove the cap from the top of the power module.

Insert a fresh 1.5V AA battery (“+” end toward the cap release button),

then reassemble the power module. For longest battery life, the switch

should remain off except when the microphone is in use. Alkaline

batteries are recommended for longest life. Remove the battery during

long-term storage.

Output is low impedance (Lo-Z) balanced. The signal appears across Pins

2 and 3; Pin 1 is ground (shield). Output phase is “Pin 2 hot”— positive

acoustic pressure produces positive voltage at Pin 2.

To avoid phase cancellation and poor sound, all mic cables must be wired

consistently: Pin 1-to-Pin 1, etc.

A 3-position switch in the power module permits choice of off, on/at

response, or on/low-roll-off (via integral 80 Hz high-pass lter). The roll-off

position reduces the microphones sensitivity to popping in close vocal

use. It also reduces the pickup of low-frequency ambient noise (such as

trafc, air-handling systems, etc.), room reverberation and mechanically

coupled vibrations. To engage the lter, slide the switch toward the

“bent” line. To turn the microphone on without engaging the lter, slide

the switch toward the at line.

For use as a lavalier, attach the microphone about six inches below the

chin. Anticipate movements that may cause the microphone to rub against

or be covered by clothing, and position the microphone to avoid it.

Avoid leaving the microphone in the open sun or in areas where

temperatures exceed 110° F (43° C) for extended periods. Extremely high

humidity should also be avoided.

Architect’s and Engineer’s Specications

The microphone shall be a xed charge condenser. It shall have a cardioid

polar pattern and a frequency response of 100 Hz to 14,000 Hz. The

microphone shall operate from an external 11V to 52V DC phantom

power source or, alternatively, from a 1.5V AA/UM3 battery. It shall

be capable of handling sound input levels up to 123 dB (phantom and

battery) with a dynamic range of 96 dB (phantom and battery). Nominal

open-circuit output voltage shall be 5.6 mV (phantom) and (battery) at 1 V,

1 Pascal. Output shall be low impedance balanced (200 ohms—phantom

and battery).

The microphone shall have a 1.8 m (6') permanently attached miniature

cable connected to the power module. The power module shall house

the battery, and shall contain a switch that permits choice of off, on/at

response or on/low-roll-off (80 Hz). The output of the power module shall

be a 3-pin XLRM-type connector.

The microphone shall be 25.0 mm (0.98") long and have a diameter of

10.2 mm (0.40"). Weight shall be 8 grams (0.3 oz). The microphone shall

include a power module, a clothing clip, a windscreen, a battery, an

instrument adapter and a protective carrying case. Finish shall be low-

reectance black.
