Audio Technica ATM73a Manuals

ATM73a Cardioid Condenser Headworn Microphone Artist Series Features • Ideal for drummers, keyboard players, guitarists or anyone requiring hands-free operation • Comfortable, unobtrusive headband design with side-of-mouth pickup • Belt-mounted power module operates on battery or phantom power • Cardioid polar pattern reduces pickup of sounds from the sides and rear, improving isolation of desired sound source • Rugged design and construction for reliable performance • Switchable 80 Hz high-pass filter minimizes pickup of undesired low-frequency sounds • Also available in two additional versions (without power module) ATM73cH, ATM73cW—cable terminated for A-T wireless systems ATM73ac—unterminated cable Wired Description (ATM73a) The ATM73a is a headworn condenser microphone with a cardioid polar pattern. It is designed for use by performing musicians and others who require professional- quality vocal pickup with hands-free operation. 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 1.4 m (4.6') 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/flat response or on/ low-roll-off (via integral 80 Hz high-pass filter). The roll-off position reduces the pickup of low-frequency ambient noise. The microphone comes equipped with a power module, two windscreens and a battery. Operation and Maintenance The ATM73a 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. A 3-position switch in the power module permits choice of off, on/flat response, or on/low-roll-off (via integral 80 Hz high-pass filter). The roll-off position reduces the pickup of low-frequency ambient noise (such as traffic, air-handling systems, etc.), room reverberation and mechanically coupled vibrations. To engage the high-pass filter, slide the switch toward the “bent” line. To turn the microphone on without engaging the high-pass filter, slide the switch toward the flat line. For maximum stability and minimum visibility, the headband should be worn around the back of the head, with each cushioned support pad resting on the temple in front of the ear. The cable should remain clipped to the headband, with some slack at the boom connection. The headset is designed so the microphone descends from the left support pad. After use in high-moisture applications, such as aerobics instruction, on-stage performing, etc., remove the foam screen, wipe off the headset with a towel and permit them to air-dry. (Do not store in a closed space, such as a plastic bag, until all moisture has evaporated.) 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. Wireless Description (ATM73cH, ATM73cW) The microphone is also available in two wireless models, the ATM73cH and ATM73cW. The ATM73cH includes a 1.4 m (55”) permanently attached miniature cable terminated with a screw-down 4-pin connector for use with Audio-Technica cH-style body-pack transmitters. The ATM73cW includes a 1.4 m (55”) permanently attached miniature cable terminated with a locking 4-pin connector for use with Audio-Technica cW-style body-pack transmitters. No power module or battery is included (or required) with the ATM73cH and ATM73cW. The ATM73cH and ATM73cW dimensions, polar pattern, and included windscreens are otherwise identical to those of the ATM73a. Also available unterminated as the ATM73ac.

Architect’s and Engineer’s Specifications The microphone shall be a fixed-charge condenser designed for headworn use. It shall have a cardioid polar pattern with a uniform 120° angle of acceptance and a frequency response of 40 Hz to 15,000 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 146 dB (phantom) or 132 dB (battery) with a dynamic range of 111 dB (phantom) or 97 dB (battery). Nominal open-circuit output voltage shall be 1.7 mV (phantom) or 1.5 mV (battery) at 1 V, 1 Pascal. Output shall be low impedance balanced (200 ohms – phantom, 270 ohms – battery). The microphone shall have a 1.4 m (4.6') 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 house the battery, and shall contain a switch that permits choice of off, on/flat 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 a headworn design with an element diameter of 10.0 mm (0.39"). Weight shall be 31 grams (1.1 oz). The microphone shall include a power module, two windscreens and a battery. The microphone shall also be available in a wireless model with a

• Ideal for drummers, keyboard players or anyone requiring hands-free operation • Comfortable, unobtrusive headband design with side-of-mouth pickup • Belt-mounted power module operates on battery or phantom power • Cardioid polar pattern improves isolation of desired sound source • Also available as ATM73cW – less power module; 55" (1.4 m) cable terminated with locking 4-pin connector for A-T UniPak™ wireless systems The ATM73a requires 11V to 52V DC phantom power or a 1.5V AA battery for operation. A battery need not be in place for phantom power operation. Battery installation: 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. Alkaline batteries are recommended for longest life. Remove the battery during long-term storage. Output from the power module's XLRM-type connector 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. An integral 80 Hz high-pass UniSteep® filter provides easy switching from a flat frequency response to a low-end roll-off. The roll-off position reduces the microphone's sensitivity to popping in close vocal use. It also reduces the pickup of low-frequency ambient noise (such as traffic, air-handling systems, etc.), room reverberation and mechanically coupled vibrations. For maximum stability and minimum visibility, the headband should be worn around the back of the head, with each cushioned support pad resting on the temple in front of the ear. The cable should remain clipped to the headband, with some slack at the boom connection. The headset is designed so the microphone descends from the left support pad. 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.
