FAQs

+How long will the NiMH batteries last until they need to be recharged?

You should receive 15 hours of use from each charge of the batteries.

+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 do you replace the batteries in the receiver?

For non-rechargeable batteries (AAA alkaline), remove the battery compartment and replace the batteries with fresh AAA alkaline batteries. For rechargeable NiMH batteries, simply replace the sealed battery pack with a freshly charged pack.

+How do I recharge the NiMH batteries?

Use the Listen LA-350 8-Unit Charging/Storage unit. This unit will charge batteries that are in receivers or out of receivers.

+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).
