Saros® 2-Way Surface Mount Speakers
Saros® speakers by Crestron® deliver professional grade performance and
flexible installation in a range of popular sizes for demanding commercial
applications. Solid construction and high-end components are hallmarks of the
complete Saros speaker line. Each Saros model is engineered to achieve a
smooth, even coverage pattern, and clear, natural sound quality through the
employment of a horn-loaded titanium dome tweeter, a high-performance
damped cone woofer, and a finely tuned crossover.
Featuring a unique “QuickBall” mounting system, the Saros speakers can be
mounted to any solid, flat surface with the ability to orient and aim the speaker
in virtually any position. The QuickBall bracket achieves a very clean and
stable installation using a tool-free ball-and-socket mechanism. Simply
position the speaker as desired and flip the clamp lever closed. A security
screw is included to deter theft by preventing the lever from being released.
Saros speakers, supplied in pairs, are available in black or white and can be
painted to blend with the surrounding architecture.

Route the cables from the audio source to the intended speaker locations while
following all appropriate local codes.
2.
Attach the QuickBall mounting bracket directly to the wall or to a flush mounted
1-gang US, UK, or European electrical box, allowing the cable coming through
the wall (and the electrical box, if used) to exit through the speaker cable
access hole of the mounting bracket.
NOTE: If the mounting bracket is to be attached to an electrical box, be sure
it is also attached to surrounding framing to provide the support needed to
hold the weight of the speaker.
The QuickBall mounting bracket can also be mounted to a light pole or post
using pole mounting straps (not included).
3.
Detach the 4-pin screw terminal block connector from the speaker. Connect the
audio source’s + and - outputs to the connector’s outer + and - (IN) terminals.
Maximum wire size is 12 AWG. Use the inner + and - (THRU) terminals to
connect a second speaker in parallel.
NOTE: The number of speakers that can be added is limited only by the
specifications of the amplifier.
a.
Route the audio source’s (and a second speaker’s) wiring through the
supplied weather boot (if used). Strip the wires 1/4 in (~6 mm), twist the
strands, insert them into the terminal block, and tighten the screws to
secure them.
b. Reattach the terminal block to the speaker connector.

4. Carefully mount the speaker onto the QuickBall mounting bracket, ensuring
that the ball is fully inserted into the cavity. Rotate and set the speaker at the
desired angle, and raise the ball socket clamp lever into position against the
bottom of the speaker to secure the speaker in position. Use the supplied
security screw to prevent the lever from being accidentally pulled, which
releases the speaker.
5.
6.
Attach a security cable (SPKA-ST-15, sold separately) to the security cable
attachment point. The other end of the cable must be attached to a secondary
point able to support several times the weight of the speaker.
The Saros speakers are equipped with a 70 V/100 V matching transformer for
distributed audio systems. The transformer tap selector switch on the rear
panel is used for setting the speaker power level. Use a flat blade screwdriver
to adjust the switch.
a. For SAROS_SR4T 70 V distributed systems, use the left side settings and
select from 1.88, 3.75, 7.5, 15, or 30 watts.
b. For SAROS_SR4T 100 V distributed systems, use the right side settings
and select from 3.75, 7.5, 15, or 30 watts. The X position should not be
used.
c. For SAROS_SR6T and SAROS_SR8T 70 V distributed systems, use the
left side settings and select from 3.75, 7.5, 15, 30, or 60 watts.
d. For SAROS_SR6T and SAROS_SR8T 100 V distributed systems, use the
right side settings and select from 7.5, 15, 30, or 60 watts. The X position
should not be used.
The switch may also be set to 8Ω operation, bypassing the transformer
completely. This setting should be used only for 8 ohm audio systems.
