Hanging Microphone Array
Features
•Ideal, cost-eective solution for huddle rooms, conference rooms and
other meeting spaces
•Quad-capsule steerable microphone array designed for use with the
ATDM-0604 Digital SmartMixer™ and other compatible mixers
•When controlled by a compatible mixer, provides 360° coverage from
a potentially limitless number (bound by mixer channel count) of virtual
hypercardioid or cardioid pickups that can be steered in 30° increments to
clearly capture every person speaking in a room by using original synthetic technology (PAT.).
•Mixer-controlled tilt function provides a vertical steering option to accommodate ceilings of dierent heights
•Includes Plenum-rated AT8554 Ceiling Mount with RJ45 connectors and
push-type wire terminals for simple, secure installation with seismic cable
to secure to a drop ceiling grid
•Integral, logic-controlled red/green LED ring provides clear indication of
mute status
•High-output design with low self-noise delivers strong, natural-sounding
vocal reproduction
•Low-reflective white finish matches ceiling tiles in most environments
•Includes two 46 cm (18") breakout cables: RJ45 (female) to three 3-pin
Euroblock connector (female), RJ45 (female) to 3-pin Euroblock connector
(female) and unterminated LED conductors
•Permanently attached 1.2 m (4') cable with locking grommet enables
quick microphone height adjustment
•UniGuard™ RFI-shielding technology oers outstanding rejection of radio
frequency interference (RFI)
•Requires 11 V to 52 V DC phantom power

• Output from the microphone is low impedance (Lo-Z) balanced. The signal appears across the pair of each output Euroblock connectors on the RJ45 breakout
cables. Audio ground is the shield connection. Output is phased so that positive
acoustic pressure produces positive voltage on the left side of each Euroblock
connector.
• MIC1 is “O” (omnidirectional), MIC2 is “L” (figure-of-eight) positioned horizontally
at 240°, MIC3 is “R” (figure-of-eight) positioned horizontally at 120°, and MIC4 is
“Z” (figure-of-eight) positioned vertically.

LED control
• To control the LED indicator ring, connect the LED Control terminals of the RJ45 breakout cable to the GPIO port of the automatic mixer or other logic device.
• When using the product with a mixer with no GPIO terminal, the LED ring can be kept permanently lit by connecting the black (BK) or violet (VT) wire to the GND terminal.
When the black wire is shorted, the LED ring will be green. When the violet wire is shorted, the LED ring will be red.
