| The ATM350 is intended for use in professional applications where
remote power is available. It requires 11V to 52V DC phantom
power, which may be provided by a mixer or console, or by a
separate, in-line source such as the Audio-Technica AT8801
singlechannel or CP8506 four-channel phantom power supplies.
An integral 80 Hz 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.
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.
To avoid phase cancellation and poor sound, all mic cables
must be wired consistently: Pin 1-to-Pin 1, etc.
To use the 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
flap 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.
Features:
- Low-profile design for minimum visibility
- Attaches to brass, reeds, piano, acoustic bass, snare, toms,
and violin
- 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
- Crisp, clear, well-balanced response, even at high SPLs
- Cardioid polar pattern reduces pickup of sounds from the
sides and rear, improving isolation of desired sound source
- Interchangeable elements available for hypercardioid and
omnidirectional polar patterns
- Corrosion-resistant contacts from gold-plated XLRM-type
connector
- Rugged, all-metal design and construction for years of
trouble-free use
