Manual Getting Started Getting Started 1 Turn off power to all com ponents before making any connections When making connections des ignate red RCA plugs as right and designate white black or grey plugs as left This is a good idea for all sig nal connections made in your audio system The key is consistency Stick with the same color coding and you ll reduce possible problems Whenever possible keep power cords away from signal cables to pre vent induced hum This is especially important if you bundle the cables to keep the installation neat looking Use quality interconnect cables We know from experience that really cheap cables can cause a multitude of problems They tend to break inside or corrode causing a loss of signal or hum They also have poor shielding If you need to run the RCA audio cables more than 20 feet consider using an active balanced line driver for the signals This will provide better noise rejection against nasty things like hum spikes local talk radio and metaphysical paranormal phenomena etc The AudioControl balanced line driver components BLD 10 BLR 10 and BLX 10 are an excellent way to send audio over long distances with standard Cat 5 wiring Check them out at audiocontrol com If you are using the A and B digital inputs and running higher resolution sample rates 96 kHz use high qual ity interconnect cables AudioContror 8 Making Good S
