AT8035
Line + Gradient Condenser Microphone
broadcast & production microphones
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, use the end tip of a paperclip or other small pointed instrument to slide the switch toward the “bent” line.
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.
Features
• Designed for video production and broadcast (ENG/EFP) audio acquisition
• Provides the narrow acceptance angle desirable for long-distance sound pickup
• 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 AT8035 is a xed-charge condenser microphone with a line + gradient polar pattern. It is designed for video production, broadcast (ENG/EFP) audio acquisition, wildlife recording and high-quality sound reinforcement.
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 highly directional polar pattern provides a narrow acceptance angle along with crisp, intelligible audio reproduction desirable for long-distance sound pickup.
The output of the microphone is a 3-pin XLRM-type connector.
A switch 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. The included AT8405a stand clamp permits mounting on any microphone stand with 5/8"-27 threads. A windscreen, two o-rings, a battery and a protective carrying case are also included.
Note: To use the microphone with a camera-mount microphone holder whose diameter is too large to secure the microphone, slide the two supplied o-rings onto the microphone handle, spaced so that one ts just in front of, and the other ts just behind, the rubber nubs inside the microphone holder. When the top of the microphone holder is closed and tightened down, the o-rings should hold the microphone securely in place.
Architect’s and Engineer’s Specications
The microphone shall be a xed-charge condenser. It shall have a line + gradient polar pattern and a frequency response of 40 Hz to 20,000 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 132 dB (phantom) or 120 dB (battery) with a dynamic range of 110 dB (phantom) or 98 dB (battery). Nominal open circuit output voltage shall be 12.5 mV (phantom) or 11.2 mV (battery) at 1 V, 1 Pascal. Output shall be low impedance balanced (250 ohms – phantom, 300 ohms – battery).
The output of the microphone shall be a 3-pin XLRM-type output connector.
The microphone shall include a switch that permits choice of at response or 80 Hz low-frequency roll-off.
The microphone shall be 369.0 mm (14.53") long and have a diameter of 21.0 mm (0.83"). Weight shall be 170 grams (6.0 oz). The microphone shall include a stand clamp, a windscreen, two o-rings, a battery and a protective carrying case.

Operation and Maintenance
The AT8035 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, unscrew the lower section of the microphone body, just below the nameplate. Insert a fresh 1.5V AA battery in the handle compartment (“+” end up), then reassemble the microphone. Alkaline batteries are recommended for longest life. Remove the battery during long-term storage.
