hole and is less likely to damage the table surface.)
5. Using a 1.5 mm ( 1 /
16
") drill bit, drill three pilot holes for the mounting
screws. (If mounting below the table surface, be certain NOT to drill
pilot holes through the table.)
6. Place the AT8474 mount over the hole and partially tighten the
three screws. Then place the microphone in the AT8474 so that the
microphone’s power module (base) extends through the AT8474 mount
into the hole. Tighten all three screws evenly. For maximum security,
the screws should be tight enough to ensure that the microphone is
held securely in place and cannot be removed without loosening
the screws.
7. If mounting the AT8474 mount below the surface of the table, slide
the rubber trim ring over the microphone (above the table surface) and
seat it between the microphone and the sides of the hole for a
finished appearance. (If mounting the AT8474 above the surface of the
table, you may also choose to use the trim ring beneath the surface of
the table, for added attenuation of noise, shock and vibration.)
8. After installing the microphone, assure maximum shock mount
effectiveness by providing some slack in the connecting cable. The cable
can be secured to the table with a standard wire clip or cable tie (not included).
Architect’s and Engineer’s Specifications
The microphone shall be a fixed-charge condenser designed for
permanent installation or portable applications. It shall have a cardioid
polar pattern with a uniform 120° angle of acceptance and a frequency
response of 30 Hz to 20,000 Hz. It shall be capable of accepting
optional interchangeable elements for additional polar patterns. The
microphone shall operate from an external 11V to 52V DC phantom
power source. It shall be capable of handling sound input levels up
to 138 dB with a dynamic range of 109 dB. Nominal open-circuit
output voltage shall be 10.0 mV at 1 V, 1 Pascal. Output shall be low
impedance balanced (250 ohms). It shall offer outstanding rejection of
radio frequency interference (RFI).
The microphone shall incorporate a self-contained power module with an
XLRM-type connector at the base for direct connection to a mating XLRF-
type panel jack or cable connector. It shall include a recessed switch to permit
choice of flat response or 80 Hz low-frequency roll-off. The microphone
shall incorporate an illuminating mute switch in the power module.
The mute switch shall illuminate when the microphone is on. The mute
switch shall be quiet in operation with no mechanical clicks or pops and
shall always return to the off position (after momentarily turning on to
verify microphone connection) when phantom power is restored.
A universal isolation-type shock mount suitable for above or below
surface installation shall be supplied for mounting the microphone in a
solid surface. It shall be possible to firmly secure the microphone in the
mount. The mount shall include appropriate hardware for installation. For
alternative mounting and portable applications, the microphone shall be
supplied with a stand clamp to permit attaching the microphone directly
to a standard 5 /
8
"-27 or 3 /
8
"-16 thread. A two-stage foam windscreen shall
also be included.
The microphone shall be a small-diameter double gooseneck design,
with an overall length of [304.8 mm (12.00"): ES915SC12]; [381.0 mm
(15.00"): ES915SC15]; [457.2 mm (18.00"): ES915SC18]; [533.4 mm
(21.00"): ES915SC21] [609.6 mm (24.00"): ES915SC24] and a head
diameter of 8.4 mm (0.33"). Weight shall be [125 grams (4.4 oz):
ES915SC12]; [130 grams (4.6 oz): ES915SC15]; [135 grams (4.8 oz):
ES915SC18]; [140 grams (4.9 oz): ES915SC21]; [145 grams (5.1 oz):
ES915SC24]. Finish shall be low-reflectance black.
The Audio-Technica [ES915SC12]; [ES915SC15]; [ES915SC18];
[ES915SC21]; [ES915SC24] is specified.
