DESCRIPTION
The TOA EM-700 features an unobtrusive, low-profile design that has
been optimized to deliver optimal performance when used on a desk-top
surface. A low-cut filter switch is included to prevent low-frequency
ambient noise surrounding the desk from being picked up. It is ideal for
speech and recording applications, such as at meetings, lectures, and
religious services. The EM-700's electret condenser microphone element
has a cardioid pickup pattern with a high degree of sensitivity, as well as
off-axis undesirable sound rejection that minimizes potential feedback.
High-frequency response is excellent, for clear audio output even when
broadcasting through a PA system.

ARCHITECTURAL AND
ENGINEERING SPECIFICATIONS
The low-profile boundary microphone shall be
designed to be placed on a flat surface for sound
pick-up applications, and have an electret condenser
microphone element with a cardioid polar pattern
that rejects off-axis sound, for focused pickup.
Frequency response shall be 35 Hz to 20 kHz.
Rated impedance shall be 120 Ω, balanced, and
rated sensitivity shall be –33 dB (1 kHz 0 dB=1
V/Pa). A low cut filter switch (100 Hz, -12 dB/oct)
shall minimize ambient noise interference. The
microphone shall be powered by any phantom
power source supplying 9 – 52 volts.
The output connector shall be XLR-3-12 equivalent,
and cable length shall be 7.5 m (24.61 ft). Operating
temperature shall be 0° C to +40° C (32° F to 104°
F). Body finish shall be die-cast aluminum, and
punched net surface-treated shall be steel plate,
both with black matte-finish paint. Dimensions shall
be 83 (W) × 23 (H) × 83(D) mm (3.27" × 0.91" ×
3.27") (excluding cord), and weight shall be 290 g
(0.64 lb). The microphone shall provide pure, natural
sound quality, and be ideally suitable for installation
on a lecture desk or meeting room table-top.
The boundary microphone shall be TOA model
EM-700.
