LSC4S

7

This device is NOT designed to be used as a music system. 

The LSC4S is a 4 channel stereo speaker comparator, used as a 
sales tool to compare the quality of up to 4 different speaker pairs. 
Speaker comparing is mostly done in demo situations or audio 
shops, to allow end users to hear the quality difference between 
multiple speaker (-pairs).

The LSC4S is equipped with 2 stereo line inputs for source 
connection (preferably CD player with highest quality) and 4 stereo 
class-D amplified outputs. The unit has a built-in webserver and 
WiFi Access Point for TCP/IP connection for control through any 
mobile device or computer that has a web browser installed.
