what is this device used for and is there anything else that goes with this device to make it operatable or is it just the earphone and sr-50 and you can hear whomever?
Asked by: Anonymous
The SR50 receiver is part of a complete Assistive Listening system. A wireless transmitter unit is required that will send signal to the SR50. Options available would be the portable PST-170 or the table top ST-300 transmitter unit. For a stand alone unit, the Williams Sound Pockettalker requires no additional hardware.

Does this device support stereo headphones or just single earphone? I understand that the audio would likely be mono but will the device drive mono audio to both earphones?
Asked by: Owfownugi
