Audio Technica ES961RC Installation And Operation

ES961RC
element for applications that require a constant signal from the
microphone element. A recessed switch on the bottom of the microphone
allows selection of local or remote operation. (In remote operation, the
LED and electronic touch switch operate independently of the
microphone.) A third position on this switch enables the LED to be
controlled from an external source.
The ES961RC is equipped with UniGuard
which offers outstanding rejection of radio frequency interference (RFI).
The microphone's cardioid polar pattern provides a 120° angle of
acceptance (cardioid in hemisphere above mounting surface).
Additional interchangeable elements with hypercardioid and omnidirec-
tional pickup patterns are available.
The ES961RC is supplied with a 25' (7.6 m) output cable. The cable
terminates in a TA5F-type connector at the microphone end. The
equipment end is unterminated stripped and tinned pigtails. This allows
the installer flexibility in interfacing with a variety of equipment. The
microphone is equipped with Audio-Technica's unique PivotPoint
output connector that allows the cable to exit from either the rear or the
bottom of the microphone without the need for tools or disassembly.
The ES961RC can be powered from any 11V to 52V DC phantom
power source. A recessed switch permits choice of flat response or
low-frequency roll-off (via integral 80 Hz high-pass UniSteep
help control undesired ambient noise. The microphone's heavy die-cast
case and non-slip silicon foam bottom pads minimize coupling of
surface vibration to the microphone. The ES961RC is equipped with a
low-reflectance black finish.
INSTALLATION AND OPERATION
The ES961RC requires 11-5V DC phantom power to operate.
The microphone should be placed on a flat,
unobstructed mounting surface, with the front of
60°
the microphone facing the sound source. The
IDEAL
WORKING
sound source should not be below, or higher
ANGLE
than 60° above, the plane of the mounting surface.
The electronics in the microphone can take up to 30 seconds to stabilize
after power is applied; during this start-up period, some sonic distur-
bances may be heard upon switching if the system is "live."
The ES961RC features a touch-sensitive on/off switch, indicator LED
and external contact closure ability for controlling remote devices. The
touch switch can be configured for touch-on/touch-off, momentary on
("press to talk"), or momentary off ("press to mute"). Slide the switch
marked "SW. FUNCTION" (located on the bottom of the microphone) to
the appropriate mode. The indicator LED and external contact closure
follow the operation of the touch switch, when in the local mode.

DESCRIPTION
The ES961RC is a wide-range
condenser microphone with
cardioid polar patter n. It is
designed for surface-mounted
applications such as high-quality
sound reinforcement, conferencing,
professional recording, and other
demanding sound pickup situations.
The microphone features an ultra-
quiet electronic touch switch,
programmable external contact
closure and LED indicator. The
electronic touch switch can be set
to any of three operating modes:
"touch-on/touch-off," "touch-to-talk"
and "touch-to-mute". The micro-
phone's external contact closure
capability permits control of remote
devices. The contact closure can
also be configured to operate
independently of the microphone
® RFI-shielding technology,
®
For applications that require the microphone to remain active or always
"on," regardless of the touch switch setting, a "Local/Remote/ LED
Remote" control function is provided.
• When the switch marked "CONTROL" (located on the bottom of
the microphone) is in the "Local" position, the touch switch
controls the microphone's audio output, LED status and contact
closure internally.
• When the "CONTROL" switch is in the "Remote" position, the
microphone's audio output remains active or "on" all the time.
The touch switch controls only the LED and contact closure.
• When the "CONTROL" switch is in the "LED remote" position, it
allows remote control of the LED, for accurate depiction of the
microphone's live status. The LED will remain "on" when driven
logic high or open, and "off" when driven logic low or connected
to ground. The microphone's audio output remains active or "on"
all the time, and the contact closure follows the configuration of
the touch switch

Output is low impedance balanced. The signal appears across the red
filter) to
and yellow wires; audio ground is the shield connection. Output is
phased so that positive acoustic pressure produces positive voltage on
the yellow wire. The small-diameter black and blue wires are the
contact closure. The white wire is the external LED control.
An integral 80 Hz high-pass filter provides easy switching from a flat
frequency response to a low-end roll-off. To reduce the pickup of low-
frequency ambient noise, slide the "Low Cut" switch to toward the
"bent" line.
The ES961RC can be mounted to a flat surface using two panhead
screws 2.26" (57.4 mm) apart, in conjunction with the keyhole slots on
the microphone underside.
While a modern condenser microphone is not unduly sensitive
to the environment, temperature extremes can be har mful.
Avoid leaving the microphone in the open sun or in areas where tem-
peratures exceed 110° F (43° C) for long periods of time. Extremely
high humidity should also be avoided.
NOTE: Audio-Technica has developed a special RFI-shielding mecha-
nism that is an integral part of the connectors in the Engineered Sound
line. If you remove or incorrectly replace the connector, you may
adversely affect the unit's RFI immunity. Audio-Technica offers a crimp
tool (ATCT) and RFI shields for TA3F-type, TA5F-type and XLRM-type
connectors that enable you to shorten the cable and correctly reinstall
the connector while maintaining the highest level of RFI immunity.
NOTE: Placing any object on a surface (such as a conference table)
before its finish is fully cured may result in damage to the finish.
