Prime Level IV Stationary
RF System (72 MHz)

Product Overview:

The LS-70 comes equipped with the LR-4200-072 receiver, Listen's new generation of personal listening products, iDSP or Intelligent Digital Signal Processing.€The
iDSP 72 MHz receiver revolutionizes how an RF system works, offering precise clarity with 20 dB less hiss than other RF receivers.€

The new integrated neck loop improves the experience for people who have hearing aids and cochlear implants with telecoils. Sleek and small, the iDSP receiver
has a field replaceable, non-proprietary rechargeable Lithium-ion battery, making obsolete the use of alkaline and NiMH batteries. Battery life is eight hours, with a

2.5-hour charge time.

The result is an innovative personal listening technology and solution that delivers an exceptional listening experience for end users and an optimal experience for
the venues that provide listening devices.

Great for larger venues to deliver an optimum range of up to 1,500 ft. (457.2m). Includes the LA-381 drop-in charging/dispensing station for the Listen iDSP
products. It is engineered for€streamlined dispensing, collecting and care of the iDSP LR-4200 RF listening devices. The charging tray can be mounted several ways;
wall, drawer, rack, or table top - all for easy dispensing. An optional cable management system can be ordered to keep the dispensing station looking neat and
organized.€

The included integrated neck loop/lanyard and signage ensures the system meets the minimum legislative requirements for veunes with a capacity up to 100.€

Highlights:

• Advanced DSP SQTM€noise reduction technology delivers 20 dB less noise and hiss than any other listening device

• Integrated neck loop / lanyard with DSP loop driver improves the listening experience for T-coil users

• Smallest device of its kind makes it easier to wear and for venues to dispense, store and maintain

• Limited Lifetime Warranty with hassle-free support

• Advanced green battery technology dramatically reduces costs of ownership and hassles while reducing the number of batteries in the landfill

• Includes drop-in charging/dispensing station for€streamlined dispensing, collecting and care of up to (12) iDSP RF listening devices

• Ensures public venues deliver an exceptional listening experience while meeting new legislative requirements for assistive listening
