Using the Behringer DS2800 is a breeze. First, connect your audio source to the 2 ultra - low noise line inputs. You can choose between the two operation modes: send 2 audio signals to 4 zones or a single signal to 8 zones. Adjust the independent level controls on each of the 8 output channels to get the right volume. The 5 - segment LED meters will show you the signal activity. When it comes to power, just plug it into a 100 - 240 V~ power source. For safety, make sure the power is off when making connections. Keep the unit in a dry and cool place. Regularly check the gold - plated XLR connectors for any signs of damage or dirt. If there's dirt, use a soft, dry cloth to clean them gently.
