out s tan d i ng r e j ecti o n of r a dio
frequency interference (RFI). The
microphone is RoHS compliant –
free from all substances specified
in the EU directive on hazardous
substances.
The microphone should be placed on a at, unobstructed mounting
surface. The small diameter capsule near the boundary eliminates
phase distortion and delivers clear, high-output performance.
The microphone requires 11V to 52V phantom power for operation.
The microphone is enclosed in a heavy-duty die-cast case and
protected by a two-layer steel mesh grille. The low-profile housing
has a low-reflectance black finish. Isolators are included with the
microphone for optional mechanical isolation from the mounting
surface.
Output is low impedance balanced. The balanced signal appears
across Pins 2 and 3, while the ground (shield) connection is Pin 1.
Output is phased so that positive acoustic pressure produces positive
voltage at Pin 2 in accordance with industry convention.
To mount the AT846/C in a ceiling or table top without the isolators,
a 20.5 mm diameter hole is required. To mount the AT846/C with the
isolators, a 23.5 mm hole is required. Place the isolators on either
side of the hole to achieve mechanical isolation from the mounting
surface. The small cardioid circle on the AT846/C bezel indicates the
"front" of the microphone.
The microphone shall be a xed-charge condenser designed for use
in table, ceiling or panel-mount boundary applications. It shall have
a frequency response of 60 Hz to 20,000 Hz and an unidirectional
(cardioid in a hemisphereabove the mounting surface boundary)
polar pattern. It shall incorporate a self-contained power module
and require 11V to 52V DC phantom power to operate. It shall offer
outstanding rejection of radio frequency interference (RFI). It shall be
capable of handling sound input levels up to 134 dB. Nominal open
circuit output voltage shall be 14.1 mV at 1 kHz, 1 Pascal. Output
shall be low impedance balanced (100 ohms) from an integral 3-pin
XLRM-type connector.
The microphone shall have a maximum diameter of 30.0 mm and an
overall length of 64.6 mm. Weight shall be 48 grams. The microphone
shall be housed in an all-metal case with a two-layer steel mesh
grille. Finish shall be low reflectance black. A small cardioid circle
on the bezel shall indicate the "front" of the microphone. Resilient
isolators shall be provided for reduction of mechanical noise transfer
from the mounting panel.
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.
