LS2 and LR2 Balanced Audio Sender/Receiver  
The Sonance LS2 and LR2 form a system designed to send unbalanced signal. This virtually eliminates any noise picked-  
low-level audio signals long distances and in close proxim- up over the length of the wire, leaving only the original signal.

The LS2 and LR2 are always used in conjunction with each

with balanced inputs or outputs (such as professional  
lengths of audio cable (under 20 feet) and wherever the

• The LS2 and LR2 operate on a single-output 12V DC  
power supply (included with both units), and can also be  
powered directly by 12V sources. The power inputs have  
reverse-polarity protection.
