5.) RCA Inputs (Channel 2 only) - The stereo unbalanced RCA inputs allow you to play a CD player,iPod or other line-level source.

6.) Thru Output - This is a male XLR-type connector that produces exactly the same signal that is connected to the main input jack or a mix of channels 1 and 2

7.) Ch 1 / Mix Switch (Thru Ouput) - This switch allows you to choose whether only the channel 1 signal (pre-gain) is sent out to the next loudspeaker (switch out - ch1) or if a mix of the channel 1 and 2 signals are sent out to the next loudspeaker (switch in - mix) (post-gains)

8.) Speaker Mode - You are able to change the loudspeaker's speaker mode to tailor it to best suit your particular application

9.) Feedback Destroyer - The multi-band  feedback destroyer hunts down offending feedback frequencies and applies up to four notch filters automatically to destroy feedback and maximize gain prior to feedback.

10.) Main Logo Switch/Limit LED  - The running man logo on the front of the SRM loudspeaker illuminates when this switch is disengaged and AC power is available at the mains input.
