KYRO KEI4

The KYRO KEI4 AEC Input Card delivers a 4-channel Acoustic Echo Cancellation (AEC) function. Similar to the analog input card, it features a +48V phantom power supply, a -60 dBu to +24 dBu level control range, and a 0 dBu to +54 dBu gain control. This card provides broadband AEC processing with an impressive tailing time of up to 512 ms. Notably, each channel of the AEC input card offers independent input and direct output for seamless local amplification.
