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 microphones 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 ohmsphantom
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.
