Thank You for Choosing Parasound

Your new Parasound

®

 Halo JC 2 preamplifier represents the pinnacle of analog audio technology. 

The JC 2 was originally conceived by Parasound president, Richard Schram, as a companion for 
the famed Halo JC 1 mono power amplifier. In the spirit of the JC 1, Parasound commissioned 
John Curl and CTC builders to design a two channel preamplifier without compromise. It uses 
the highest quality parts and achieves a higher level of sonic and measured performance than 
any preamplifier we’ve made since Parasound was founded in 1981. We’re proud to offer you 
this exceptional audio component, knowing that it will bring you many years of enjoyment  
and dependability.
We appreciate your taking the time to read these instructions and thank you for selecting  
Parasound. For updates and corrections to this manual, we invite you to check our web site,

Enjoy.
