The audio output is available on our CKB304V1, CKB304V2, and CKB312V1 models, and it only transmits the digital audio data from the Bridge, but it is not amplified. You as an integrator will need to amplify the audio depending on the needs of the site/customer.
To begin broadcasting the audio you will need to remove the silicon cap on the
3.5mm port on the side of the Bridge and plug in the 9in male to female audio extension adapter cable that came with your Bridge.
From the female end of the audio cable, you may now plug in a speaker with your desired amplification.
