Product Overview
Lectrosonics' 1624 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 1624 is now part of your network.
