Audio-Technica AE2500 Specifications
• Revolutionary dual-element design features two elements
(condenser and dynamic) enclosed in a single-housing
• Dynamic element delivers the aggressive attack of the beater
while the condenser captures the round tonalities of the shell
• Elements are positioned in a perfect phase relationship,
something practically unachievable with two separate
microphones
• Robust design for enduring dependability on the road
• Integral 80 Hz HPF switch and 10 dB pad (condenser element)
The AE2500 is intended for use in professional applications where
remote power is available.It requires 11V to 52V DC phantom power
only to the condenser output of the supplied cable.
Output from the microphone's 5-pin XLRM-type connector is lowimpedance (Lo-Z) balanced.The included 16.5' (5 m) shielded cable
features a 5-pin XLRF-type input connector and two standard 3-pin
XLRM-type output connectors. The balanced signals appear across
Pins 2 and 3 (condenser) and Pins 4 and 5 (dynamic). Pin 1 is
ground (shield). Output is phased so that positive acoustic pressure
produces positive voltage at Pins 2 and 4.
To avoid phase cancellation and poor sound, all mic cables must be
wired consistently: Pin 1-to-Pin 1, etc.
An integral 80 Hz hi-pass filter provides easy switching from a flat
frequency response to a low-end roll-off.The roll-off position reduces
the microphone’s sensitivity to popping in close vocal use. It also
reduces the pickup of low-frequency ambient noise (such
as traffic, air-handling systems, etc.), room reverberation and
mechanically-coupled vibrations.
The AE2500 includes an AT8471 isolation clamp to provide secure
mounting, versatile positioning, and effective dampening of unwanted mechanical noise.
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. Take care to keep
foreign particles from entering the windscreen. An accumulation of
iron or steel filings on the diaphragm, and/or foreign material in the
windscreen's mesh surface, can degrade performance.
