ATM350a Description

The ATM350a is a fixed-charge condenser microphone with a cardioid polar pattern. It is designed for use in professional live-sound and studio applications.

When used with the available mounts and mounting systems, it provides accurate, consistent pickup of brass, woodwind, piano, drums and many other musical instruments.

The flexible gooseneck allows for precise microphone positioning even under demanding performances.

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 4m (13.1') permanently attached miniature cable. Its free end connects to the provided AT8543 power module via a locking 4-pin connector. The output of the power module is a 3-pin XLRM-type connector.

A switch in the power module permits choice of flat response or low-frequency roll-off (via integral 80Hz high-pass filter) to help control undesired ambient noise.

The microphone is enclosed in a rugged housing with a low-reflectance black finish.

ATM350acW Description

The microphone is also available as the ATM350acW wireless model. The ATM350acW features a 1.4 m (55") miniature cable terminated with a locking 4-pin connector for use with Audio-Technica body-pack transmitters.

The ATM350acW specifications are identical to those of the ATM350a (when using an AT8543 power module). However, no power module is included with the ATM350acW, so there is no low-cut function.

ATM350acH Description

The microphone is also available as the ATM350acH wireless model. The ATM350acH features a 1.4m (55") miniature cable terminated with a screw-down 4-pin connector for use with Audio-Technica cH-style body-pack transmitters. No power module is included (or required) with the ATM350acH. The ATM350acH specifications are identical to those of the ATM350a.

AT8490/AT8490L Description

The AT8490/AT8490L flexible gooseneck permits aiming the microphone in any direction, while a cable strain relief reduces cable-transmitted noise and cable damage. The integral windscreen entirely surrounds the microphone with foam to isolate the microphone from noise transmitted from the instrument and shield the element against accidental damage.

AT8491U Description

Universal clip-on mount features rugged metal construction to withstand the rigor of stage use. The mount is lined with rubber to provide secure mounting, shock resistance and instrument protection. Specially designed mount minimizes contact with instrument. A locking screw holds the mount securely in place.

AT8491P Description

Piano mount features a strong rare-earth magnet which permits secure mounting inside a piano or on any metal surface. The mounting base is lined with soft and protective material to avoid damaging the instrument.

AT8491W Description

The woodwind mount features an adjustable hook and loop fastener strap with rubber pad to firmly secure the mount to the instrument. Specially designed mount minimizes contact with instrument to reduce damping. Rotating gooseneck mount allows easy positioning of the microphone.

AT8491D Description

The drum mount features a patented design which uses the drum lug to securely mount the microphone while still allowing the drum to be tuned. The gooseneck can be positioned vertically or horizontally for optimal placement and a low profile appearance.

AT8468 Description

The violin mount fastens beneath the strings between the bridge and the tailpiece to provide outstanding pickup of violin and other stringed instruments.

AT8491G Description

The guitar mount features a rugged, thumbscrew-adjustable clamp with pads that attaches to guitars and other stringed instruments while leaving fewer marks. You can adjust the clamp length between 90mm (3.5") and 135mm (5.3").

AT8491S Description

The surface mount is designed for accordions and other challenging applications. The notched mount can be attached permanently using the accordion's grille screw and the included adhesive silicon pad, or it can be attached temporarily using the included fastener tape pads. A transparent protective film is also included to prevent damage to the instrument's finish.

AT8475 Description

The surface mounting kit for AT8491S includes two adhesive silicon pads, two mount fastener tape pads, two surface fastener pads, and two transparent protective films.

Operation and Maintenance

The ATM350a 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.

The 80-Hz low-cut filter switch on the AT8543 power module makes it easy to switch from flat frequency response to low-frequency roll-off. This minimizes pickup of undesired low-frequency noise, such as from air conditioning systems. To engage the high-pass filter, slide the switch toward the "bent" line.

Avoid leaving the microphone in the open sun or in areas where temperatures exceed 110^ (43^) for extended periods. Extremely high humidity should also be avoided.
