simo923 0 Posted April 17, 2008 I have 64 microphones. All knowles mics with pre amps built in, running over 150meters. Now i have a small single channel amp which works a treat, but rather than have 64 of these all hooked up, i wanted a neater solution. I bought the Behringer ADA8000 which is giving me a line output from the mic. Run it through a powered set of speakers, it runs fine. My question is this. Are the audio inputs on the GV-1480, line input or just standard audio input, it is a question of, do i need an amp in between the ADA8000 and the GV-1480 or not. Strange one i know, thanks guys.

andy_geovision 0 Posted May 5, 2008 Dear Simo, GV 1480 provides Users with standard Audio Cable... If your are running over 150 meters then yes, amp is recommended..
