Performance Stationary IR System (Discontinued)

Item:LS-81-01-GY
Discontinued

The Performance Stationary IR System is designed for installations that require mounting of the transmitter (rack mount) and radiator. The system includes four (4) Listen stetho receivers, and a convenient storage station, and an ADA compliance signage kit for venues to demonstrate ADA compliance. The system can cover up to 20,000 ft²  (1,858 m²). Listen’s IR systems are designed for applications that require the audio signal to be isolated for security or other reasons, such as assistive listening, soundfield, language interpretation, live theater, houses of worship, courtrooms, secure rooms, and for auditory description. Custom systems available. Grey or white radiator options available.

FAQs

+Can the LT-82 be operated on 230 VAC?

Yes, the LT-82 has a universal power supply that can be used anywhere in the world.

+Is there any performance degradation in stereo mode?

Yes, stereo operation raises the noise floor slightly.

+Can I operate some channels in mono and others in stereo?

Yes.

+How many carriers does the LT-82 Stationary IR Transmitter produce?

One.

+How many carriers can be produced simultaneously in a room?

Four. You will need one LT-82 Stationary IR Transmitter per carrier.

+How are radiators connected to the LT-82?

The carrier (signal) is connected using coax cable; power is connected using standard CAT-5 cabling.

+How is power delivered to the radiator?

Power is delivered with CAT-5 cables (connected between the radiator and either the LT-82 transmitter or the LA-205 power supply).

+How many radiators can be powered from the LT-82 or LA-205 power supply?

Two.

+How much coverage is provided with the LA-140 radiator?

40,000 ft² (3716 m²) single channel with LR-4200-IR/LR-5200-IR receivers or 10,000 ft² (929 m²) single channel with LR-42/LR-44 receivers

+Does the number of carriers affect the coverage?

Yes, for two sources (carriers), the total coverage is half. For four carriers, the coverage per carrier is one-fourth.

+What is the purpose of the delay compensation switch?

This switch allows you to set up delay timing in a multi-radiator system so that each radiator receives the carrier at exactly the same time. This prevents signal dropouts that can be caused by out-of-phase signals (multi-path). With Listen’s delay compensation switch, it is not necessary to cut all of your coaxial cables to the same length - your shorter runs can use shorter cables, keeping your installation clean (and cost-effective).
