Frequently Asked Questions - HD 10-A MK4 RCF
How to connect the HD 10-A MK4 speaker?
Use an XLR cable to connect your audio source (mixer, microphone, etc.) to the INPUT (combo XLR/Jack). To daisy-chain multiple speakers, connect the LINK output to the input of the next speaker.
What type of cable to use for connection?
Use a good quality balanced XLR cable to minimize interference. Avoid unbalanced Jack cables over long distances.
How to adjust volume and equalization?
