ARCHITECT'S SPECIFICATIONS
The microphone shall be Shure Model 588SA (588SB, 588SBE) or equivalent.
The microphone shall be a moving-coil dynamic type microphone with a shaped
frequency range of 80 to 13,000 Hz. This unit shall have a Cardioid polar charac-
teristic. T h e cancellation at the sides shall be approximately 6 db, and the cancel-
lation a t the rear shall be 15 to 20 db.
Model 588SA-The
microphone shall be high impedance for connection into a
high impedance input.
The microphone output shall be -59.0
db where 0 db
=
1 volt per microbar.
The microphone rating impedance shall be 40,000 ohms and the Gm (sensitivity)
at 1,000 Hz. shall be within
i 3
db of --155.0
db referenced to EIA Standard
SE-105, August 1949.
Model 588SB, 588SBE-The
microphone shall be low impedance for connection
into
a
25 to 200 ohm line.
The microphone output shall be -60.0
db where 0 db
=
1 milliwatt with 10
microbars.
T h e microphone rating impedance shall be 150 ohm and the Gm (sensitivity) at
1,000 Hz. shall be within
i
3 db of -153.0
referenced to EIA Standard SE-105,
August 1949.
The Model 588SA (588SB, 588SBE) shall be provided with a swivel adapter
adjustable through 90" from vertical to horizontal. The microphone is equipped with
a built-in "ON-OFF" switch and a one conductor (588SA) or a two conductor
(588SB, 588SBE) shielded cable having Cannon XLR-3-11C connector on micro-
phone end. The microphone swivel adapter will mount on a stand having a %"-27
thread. The overall dimensions shall be 61%2" (164.3 mm) in length and 2%"
(54.0 mm) in diameter.
