Adastra LA-300 induction loop amplifier for driving a cable loop around a room of up to 300m² to provide assisted listening for hearing aid users.

The LA-300 features a number of line-level & microphone inputs for connecting an external audio source such as a MP3/CD player, laptop/PC or TV all of which can be transmitted around the hearing loop. 

Microphone input 1 features a priority switch meaning it will override all of the other inputs when a signal is picked up. This is great for paging applications when an announcement needs to be heard loud and clear as well as general public address.

In addition to this, the LA-300 also has alarm contacts that can be fed to an alarm panel and sound a siren throughout the system ensuring everyone can be alerted in the case of an emergency.
