Frequently Asked Questions - SAROS SR4T-B-T-EACH Crestron

What is the recommended amplifier power for the SAROS SR4T-B-T-EACH?

For low impedance (8 ohms) use an amplifier rated 30W RMS per channel. For 70V/100V systems, set the tap to match the amplifier output (e.g., 30W tap for 30W line).

Can the speaker be used outdoors?

No, it is designed for indoor ceiling use only. Exposure to moisture may damage the speaker.

What is the cutout size for installation?

A 7.5 inch (191 mm) diameter hole is required. Ensure ceiling thickness is between 0.5 and 1.5 inches.

Does the speaker include a tile-bridge for drop ceilings?

No, a tile-bridge is not included. For drop ceilings, use optional CBL-4 bridge or alternative support.

What is the frequency response?

The frequency response is 60 Hz to 20 kHz, providing full-range audio for speech and music.

How do I select the transformer tap?

Set the rotary switch on the speaker to the desired wattage (30, 15, 7.5, 3.7, or 1.8W) when using a 70V or 100V amplifier. For 8 ohm operation, set to '8Ω' position.

Can the grille be painted?

Yes, the white grille is paintable. Use the included paint mask to protect the speaker during painting.

What is the warranty period?

Crestron offers a limited lifetime warranty for the SAROS series. Contact Crestron for details.

Is the speaker UL listed?

Yes, it is UL 2043 listed for plenum airspace, suitable for installation in air-handling spaces.

Can I daisy-chain multiple speakers?

Yes, in a 70V/100V system, speakers are paralleled. Ensure total tap wattage does not exceed amplifier power. For 8 ohm systems, avoid paralleling more than two speakers.

SAROS SR4T/SAROS SR6T/SAROS SR8T

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.

NOTE: Before starting installation, ensure the wall and wall material are capable of supporting the combined weight of the speakers and the wall mount assemblies. Refer to section ③ for speaker weights.

Installation

Refer to the illustration to the right as necessary, and install the speakers as follows:

1. 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).

1. 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.

1. 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.
2. 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.
3. 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 SR6T 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 8 operation, bypassing the transformer completely. This setting should be used only for 8 ohm audio systems.

Problem Solving

Troubleshooting

The following table provides corrective action for possible trouble situations. If further assistance is required, please contact a Crestron customer service representative.

TROUBLE	POSSIBLE CAUSE(S)	CORRECTIVE ACTION
There is either no sound or the sound from the speakers is intermittent.	There is a cable connection error.	Verify the cable connections between the amplifier and speakers.
	The amplifier is not receiving an input signal or there is an amplifier malfunction.	Verify that the amplifier is functioning correctly, that it is receiving an input signal, and that the correct input source is selected.
Constant noise such as buzzing, humming, or having comes from the speakers.	There is a faulty device in the system.	Verify that all devices in the system are functioning properly.
	There is a system grounding fault.	Verify the system grounding connection.
The low frequency output is poor.	Verify speaker connection polarity (i.e., + on speaker to + on amplifier).	Verify speaker connection polarity (i.e., + on amplifier to + on speaker).
