BACK OF UNIT
DESCRIPTION:
The Pro Co SAS3 Sports Announcer’s Switch is a simple,
rugged, desktop push-to-talk microphone switch designed
specically for sporting event announcers. This microphone
signal actuating device oers clean reliable performance
with any balanced or oating low-impedance (150 ohm
nominal) microphone or signal source. SAS3 is designed for
use with either condenser-type or dynamic microphones.
The SAS3 is ideally suited for use in sports event announcing
applications but is equally suitable for any application
where a desktop push-to-talk device is required. The SAS3
is backed by Pro Co’s ve-year, any excuse - even abuse
warranty.
To pass the microphone signal to the sound system, the user
simply depresses and holds down the push-to-talk button
on the SAS3. The SAS3 is a momentary press-to-talk switch,
so the switch will need to remain depressed for as long as
the user requires the signal to be “live”. Releasing the switch
will prevent the signal from continuing to the sound system.
Connections between the SAS3 and the the sound system
are made with standard microphone cables. The user’s
microphone is connected to the SAS3 through the female
microphone adapter that is incorporated into the end of
the 6-inch gooseneck mounted on the top panel of the
device. A microphone cable is integrated in the 6-inch black
chrome gooseneck. An additional Mic Input is provided via a
Female XLR-type connector located on the back panel. Both
gooseneck-mounted and rear panel Mic Inputs are wired
in parallel and are controlled by the push-to-talk switch. A
Male XLR-type connector is provided for Mic Output.
The SAS3 enclosure is formed of a 16-gauge steel top and
a rugged 11-gauge, black epoxy painted steel base. Steel
provides excellent magnetic shielding from 60Hz AC
hum elds. All control and connector function graphics
are identied on a textured polycarbonate overlay. The
enclosure is with (4) non-conductive, anti-skid feet on the
base of the unit. Top-quality connectors and switches
provide trouble-free service even in abusive situations such
as remote broadcast and recording operations.

ENGINEERING SPECIFICATIONS:
The microphone signal momentary push-to-talk unit shall be suitable for the noiseless muting of
any balanced or oating low impedance (150 ohm nominal) microphone or similar signal source.
There shall be two (2) 3-pin female XLR-type connectors wired in parallel for input from the source.
There shall be (1) 3-pin male XLR-type connector for the output. The unit shall be suitable for the
use of condenser microphones and dynamic microphones. There shall be (1) momentary push
button switch suitable for either hand or foot operation. The switch shall be single pole, single
throw, and used to allow the microphone signal to pass from input to output. The circuit shall
consist of a normally closed switch that connects pin 2 to pin 3, eectively muting the microphone
signal. Activating the switch removes the “short” between pins 2 and 3 and allows the michrophone
signal to pass to the output. The electronic components shall be wired to provide adequate pop
suppression and sucient bypass impedance, to allow noiseless operation with no signicant signal
degradation.
The enclosure shall be constructed of a 16-gauge steel top and a black epoxy texture painted
11-gauge steel base. The control and connector functions shall be identied by a textured
polycarbonate adhesive overlay that is xed to the top. The top of the unit shall slope from rear
to front. The enclosure shall be provided with a threaded base suitable for the attachment of a
exible “gooseneck ” microphone stand mounted to the top of the enclosure. The enclosure shall
be provided with (4) four nonconductive, non-skid feet on the base of the unit. The dimensions of
the unit shall be approximately 4.062” L x 6.75” W x 1.687” H at the front sloping up to 2.250” H at the
rear of the unit. (103.2mm L x 171.5mm W x 42.8/57.2mm H). These dimensions do not include the
microphone stand.
The unit shall include one (1) 6-inch , exible “gooseneck ” microphone stand with 3-pin female XLR
connector microphone input that can be xed to the enclosure-mounted base. The gooseneckmounted microphone connector input cable shall be routed through the gooseneck and wired in
parallel with the enclosure-mounted 3-pin femal XLR connector input.
The microphone signal momentary push-to-talk unit shall be a Pro Co Sports Announcer’s Switch 3
(SAS3).
CONTROLS:
MIC INPUT: Female 3-pin XLR-type connector accepts input
(Gooseneck Mount) from any balanced or oating low impedance (150
ohm nominal) microphone or similar signal source.
MIC INPUT: Female 3-pin XLR-type connector accepts input
from any balanced or oating low impedance (150
ohm nominal) microphone or similar signal source.
Wired in Parallel with gooseneck mounted Mic Input.
DIRECT OUT: Male 3-pin XLR-type connector provides output to
sound system input.

ACTIVATION SWITCH: Momentary, SPST (single pole, single throw) switch
shorts pin 2 and pin 3 of the XLR connectors
together to produce the muting eect. Depressing
the switch momentarily removes the short and allows
the microphone signal to pass to the output. The
signal can pass as long as ther switch remains
depressed.
