ATM350

Cardioid Condenser Clip-on Instrument Microphone

Features

• Attaches to brass, reeds, piano, acoustic bass, snare, toms

and violin

• Crisp, clear, well-balanced response, even at high SPLs

• Low-prole design for minimum visibility

• Cardioid polar pattern reduces pickup of sounds from the sides

and rear, improving isolation of desired sound source

• UniMount® clip permits accurate positioning, provides shock

resistance and protects element

• Unique violin mount permits unobtrusive placement of

microphone between the instrument's bridge and tailpiece

• Switchable 80 Hz high-pass lter minimizes pickup of undesired

low-frequency sounds

• Interchangeable elements available for hypercardioid and

omnidirectional polar patterns

• Also available in a wireless model, ATM350cW

ATM350 Description

The ATM350 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 trumpet and saxophone and many other musical

instruments. When used with the included violin mount, it provides

outstanding pickup of violin and other stringed instruments.

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 4 m (13.1') permanently attached miniature

cable. Its free end connects to the provided AT8542 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, a violin mount and a

soft protective pouch are included.

ATM350cW Description

The microphone is also available in a wireless model, the ATM350cW.

The ATM350cW 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

ATM350cW. The ATM350cW dimensions, polar pattern and included

instrument mount and violin mount are identical to those of the ATM350.

Operation and Maintenance

The ATM350 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.

To use the included violin mount, place the microphone in the violin

mount’s elastic mic holder. Open the hook & loop fastener; pass the hook

side of the open fastener beneath the strings between the bridge and

the tailpiece. Close the fastener ap around the strings. The microphone

should be on top, with the element facing the bridge (away from the

tailpiece).

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.
