Lectrosonics SPN812
8 In/12 Out 1RU Digital Mixer

SPN812

Lectrosonics' 812 Aspen Series mixer offers unlimited input expansion and 48 mix buses in order to give you superior scalibility.  The Proportional Gain Algorithm provides seamless auto-mixing and integrates easily with with echo cancellation, analog mixing consoles, or any other type of audio system.  And with TCP/IP addressibility for control through Ethernet, the 812 is now part of your network.
