FAQ
Q How long will the NiMH batteries last until they need to be recharged?
A You should receive 15 hours of use from each charge of the batteries.
Q Can the LT-82 be operated on 230 VAC?
A Yes, the LT-82 has a universal power supply that can be used anywhere in the world.
Q Is there any performance degradation in stereo mode?
A Yes, stereo operation raises the noise floor slightly.
Q Can I operate some channels in mono and others in stereo?
A Yes.
Q How do you replace the batteries in the receiver?
A 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.
Q How do I recharge the NiMH batteries?
A Use the Listen LA-350 8-Unit Charging/Storage unit. This unit will charge batteries that are in receivers or out of receivers.
Q How many carriers does the LT-82 Stationary IR Transmitter produce?
A One.
Q How many carriers can be produced simultaneously in a room?
A Four. You will need one LT-82 Stationary IR Transmitter per carrier.
Q How are radiators connected to the LT-82?
A The carrier (signal) is connected using coax cable; power is connected using standard CAT-5 cabling.
Q How is power delivered to the radiator?
A Power is delivered with CAT-5 cables (connected between the radiator and either the LT-82 transmitter or the LA-205 power supply).
Q How many radiators can be powered from the LT-82 or LA-205 power supply?
A Two.
Q How much coverage is provided with the LA-140 radiator?
A 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
Q Does the number of carriers affect the coverage?
A Yes, for two sources (carriers), the total coverage is half. For four carriers, the coverage per carrier is one-fourth.
Q What is the purpose of the delay compensation switch?
A 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).
Q What are the ADA changes related to assistive listening systems?
A Simply put, any public assembly area where audible communication is integral to the use of the space, an assistive listening system shall be provided. The assistive listening receivers need to comply with the following table below. For full details visit: http://www.ada.gov/2010ADAstandards_index.htm
