XL-12

• 3 inputs (including MIC)
  
• Output for loop and headphones
  
• Switchable current- or voltage-feed
  
• AGC
  
• Built-in power supply
  

The XL-12 is a combined loop- and headphone-amplifier for connection to TV, radio,
tape recorder or microphone. The XL-12 can drive a small loop, a portable mini-loop XL-22II
or headphones. You can choose between current- or voltage-feed with a switch, depending on
what type of aid is to be used (loop or headphones).

This makes the XL-12 very flexible and useful even for persons not wearing a hearing instrument.
