Frequently Asked Questions - I128SYS Atlas Sound

What is the impedance of the I128SYS speaker?

The I128SYS is a dual-impedance speaker. It operates at 8 ohms in low-impedance mode, or can be switched to 70V / 100V distributed audio systems using the tap selector.

Can I use the I128SYS outdoors?

The I128SYS is designed for indoor use only. It is not rated for outdoor or wet locations. For outdoor installations, consider Atlas Sound's weather-resistant models.

How do I select the correct tap for a 70V or 100V system?

Use the tap selector on the back of the speaker to match the transformer taps. Typical taps include 1.5W, 3W, 6W, and bypass for 8-ohm operation. Always set the total wattage of all speakers to not exceed the amplifier's power.

What is the cutout size for installation?

The required ceiling cutout is approximately 10.5 inches (267 mm) in diameter. Use the included template for accurate cutting.

Is the I128SYS suitable for high-humidity areas like bathrooms?

The I128SYS is not designed for high-humidity environments. For bathrooms or similar areas, choose an Atlas Sound model with a paintable grille and humidity-resistant components.

How do I clean the speaker grille?

Clean the grille with a dry, soft cloth. Avoid using water, cleaners, or compressed air as they may damage the speaker components.

Does the I128SYS come with mounting hardware?

Yes, the speaker includes a tile bridge for mounting in drop ceilings, along with screws and cutout template. Additional hardware for other ceiling types may be needed.

What is the warranty period for the I128SYS?

Atlas Sound provides a 5-year limited warranty from the date of purchase against defects in materials and workmanship.

Can I paint the grille to match my ceiling?

Yes, the metal grille can be painted. Remove it from the speaker, clean it, and apply light coats of water-based paint to avoid clogging the holes.

How do I connect multiple I128SYS speakers in a 70V system?

Use a daisy-chain wiring method. Connect the amplifier output to the first speaker's input, then run wires from the first speaker's output to the next. Ensure total speaker wattage does not exceed 80% of the amplifier's power.

General Description

Model I128SYS from Atlas Sound consists of a factory assembled loudspeaker, baffle, and PCB amplifier / control board securely mounted to the rear of the baffle via concealed weld studs. The amplifier / control board is capable of producing 9 Watts RMS into the 8Ω loudspeaker with 9VDC minimum power provided by AF compliant POE switches. Local 12VDC – 18VDC PSUs may also be used instead of POE switches. Interconnection is via a board mounted female RJ-45 connector. The industry standard C10A loudspeaker used in the I128SYS is a dual cone 8" (205mm) loudspeaker with a 10oz (260g) ceramic magnet. It includes a curvilinear paper cone for lower harmonic distortion. The loudspeaker is also equipped with a full 1" (25mm) diameter copper voice coil with aluminum former for better heat dissipation. The 18-gauge construction of the metal baffle provides security and durability in commercial applications. A perforated 22-gauge metal screen is provided over the loudspeaker to maximize performance by allowing the optimum percentage of open area forward of the loudspeaker. The baffle is finished in neutral white electrostatic powder coat.

Applications

The perfect choice for Education, Military / Government, and Large Scale Corporate applications. It provides the capability to simultaneously send a multicast audio stream and text messages to any combination of IP phones, Atlas Sound IP speakers, and PCs. With the push of a single button on the phone or a single click from a PC, a user can send a live, recorded, or scheduled broadcast to one or more paging groups. With IP compliant loudspeaker products from Atlas Sound, system designers and integrators will have the ability to deploy extremely large scale and complex paging systems over new or existing networks with the convenience of centralized administration by IT personnel.

Extreme cost savings can also be realized from the elimination of separate "stand alone" paging & clock / bell systems when ControlKom™ is utilized in education applications in conjunction with the model I128SYS speaker system.
