Cardioid Condenser Headword Microphones ATM75 / ATM75cW / ATM75cH
Thank you for purchasing this product. Before using the product, read through the user manual to ensure that you will use the product correctly. Please keep this manual for future reference.
Features
· Ideal for drummers, keyboard players, guitarists or anyone requiring hands-free operation · Low-visibilty headband provides stable, comfortable fit · Pivot-mounted flexible mic boom descends from left or right side · Belt-mounted power module operates on battery or phantom power · Cardioid polar pattern improving isolation of desired sound source · Rugged design and construction for reliable performance · ATM75 wired version's power module (AT8531) includes a switchable 80 Hz high-pass filter
minimizes pickup of undesired low-frequency sounds · Wireless version equipped with cW-style locking or cH-style screw-down 4-pin termination
for Audio-Technica wireless systems
Notes on use
ATM75 wired version includes a power module AT8531 that 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. The output of the power module is a 3-pin XLRM-type connector.
An integral 80Hz high-pass filter provides easy switching from a flat frequency response to a low-end roll-off. 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.
ATM75cW and ATM75cH wireless versions do not contain power module and includes clothing clip and metal-frame pop filter only. 1.4 m cable terminated with locking 4-pin connector. The connector is also compatible with Audio-Technica cW and cH type body-pack transmitters.
Avoid leaving the microphone in the open sun or in areas where temperatures exceed 43°C for extended periods. Extremely high humidity should also be avoided.
Safety precaution
Although this product was designed to be used safely, failing to use it correctly may result in an accident. To ensure safety, observe all warnings and cautions while using the product.
Cautions for the product
· Do not subject the product to strong impact to avoid malfunction. · Do not disassemble, modify or attempt to repair the product. · Do not handle the product with wet hands to avoid electric shock or injury. · Do not store the product under direct sunlight, near heating devices or in a hot, humid or
dusty place.
Connection procedure
Connect the output terminals of AT8531 power module to a device that has a microphone input (balanced input) compatible with a phantom power supply. The output connector is an XLRM-type with polarity as shown in the figure below.
