DESCRIPTION
The TOA EM-600 has an unobtrusive design that allows simple flushmounting in walls, ceilings and desktops, making it particularly well-suited
for conference room recording, as well as in security monitoring
applications. An electret condenser microphone element’s omnidirectional
pickup pattern ensures a high degree of sensitivity and a wide frequency
range. The EM-600’s has been designed to minimize interference from
low-frequency sounds that may degrade audio reproduction. It also
incorporates two rubber isolation rings to resist vibrations that may
adversely affect audio quality.

ARCHITECTURAL AND
ENGINEERING SPECIFICATIONS
The flush-mount boundary microphone shall be
designed for sound pick-up applications, be 28 mm
(1.1") in diameter, and have an omnidirectional
electret condenser microphone element. It shall be
unobtrusively mountable into a ceiling, wall or desk.
Frequency response shall be 30 Hz to 20k Hz.
Rated impedance shall be 120 Ω, balanced, and
rated sensitivity shall be –36 dB (1k Hz 0 dB=1
V/Pa). A 50 Hz low-cut filter shall reduce intrusive
noise. The microphone shall be powered by any
phantom power source supplying 9 – 52 volts.
The output connector shall be XLR-3-12
equivalent. Operating temperature shall be 0° C to
+40° C (32° F to 104° F). Body finish shall be steel,
and head finish shall be zinc-plated steel wire, both
with white semi-gloss paint. Dimensions shall be
ø28 x 68 mm (ø1.1" × 2.68"), and weight shall be
85 g (0.19 lb). Two rubber isolation rings and an
M20 nut shall be provided as accessories. The
microphone shall provide clear and high-quality
sound, and be well-suited for conference recording
and security monitoring applications.
The flush-mounted boundary microphone shall be
TOA model EM-600.
