and rear, improving isolation of desired sound source
• UniMount
®
clip permits accurate positioning, provides shock
resistance and protects element

low-frequency sounds
• Also available in a wireless model, PRO 35cW
PRO 35 Description
The PRO 35 is a xed-charge clip-on condenser microphone with a
cardioid polar pattern. It is designed for use in professional live-sound and
studio applications.
When used with the included instrument mount, it provides accurate,
consistent pickup of reeds, brass and percussion.
The microphone requires 11V to 52V phantom power for operation.
The cardioid polar pattern of the microphone is more sensitive to sound
originating directly in front of the element, making it useful for controlling
feedback and reducing pickup of unwanted sounds.
The microphone includes a 1.8 m (6') permanently attached miniature
cable. Its free end connects to the provided AT8538 power module via a
TA3F-type connector. The output of the power module is a 3-pin XLRM-
type connector.
A switch in the power module permits choice of at response or low-
frequency roll-off (via integral 80 Hz high-pass lter) to help control
undesired ambient noise.
The microphone is enclosed in a rugged housing with a low-reectance
black nish. A power module, an instrument mount and a soft protective
pouch are included.
PRO 35cW Description
The microphone is also available in a wireless model, the PRO 35cW.
The PRO 35cW features a 1.4 m (55") miniature cable terminated with
a locking 4-pin connector for use with Audio-Technica UniPak
®
body-
pack transmitters. No power module is included (or required) with the
PRO 35cW. The PRO 35cW dimensions, polar pattern and included
instrument mount are identical to those of the PRO 35.
Operation and Maintenance
The PRO 35 requires 11V to 52V phantom power for operation.
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.
An integral 80 Hz high-pass lter provides easy switching from a at
frequency response to a low-end roll-off. The roll-off position 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 high-pass lter, slide the switch toward the “bent” line.
The included UniMount
®
instrument mount entirely surrounds the
microphone with foam to isolate the microphone from noise transmitted
from the instrument, shield the element against accidental damage,
and provide an efcient wind screen. The exible arm permits aiming
the microphone in any direction, while a cable strain relief reduces
cable-transmitted noise and cable damage. The rubber grip spring clamp
securely holds the microphone to the instrument without marring the
surface.
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 with a uniform 120° angle of acceptance and
a frequency response of 50 Hz to 15,000 Hz. The microphone shall
operate from an external 11V to 52V DC phantom power source. It shall
be capable of handling sound input levels up to 145 dB with a dynamic
range of 115 dB. Nominal open-circuit output voltage shall be 5.6 mV at
1 V, 1 Pascal. Output shall be low impedance balanced (250 ohms).
The microphone shall have a 1.8 m (6') permanently attached miniature
cable terminating in a TA3F-type output connector. The output connector
shall connect to a TB3M-type jack on the included power module. The
power module shall contain a switch that permits a choice of at response
or 80 Hz low-frequency roll-off. 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) without cable. The
microphone shall include a power module, an instrument mount and a
soft protective pouch.
The microphone shall also be available in a wireless model with a 1.4 m
(55") miniature cable terminated with a locking 4-pin connector for use
with Audio-Technica UniPak
®
body-pack transmitters. No power module
shall be required or included with the wireless model. The wireless
model dimensions, polar pattern, and included instrument mount shall be
identical to those of the wired model.
