XONE:S6 User Guide 25
To ensure safe and trouble-free operation we recommend the following:
• Have your mains system checked by a qualified electrician If the supply grounding is solid to start
with you are less likely to experience problems.
• Do not remove the ground connection from the power unit mains plug The console chassis is
connected to mains ground through the power cable to ensure your safety. Audio 0V is connected to
the console chassis internally.
• Make sure that turntables are correctly grounded Chassis ground terminals are provided on the
console rear panel to connect to turntable earth straps.
• Deal with ground loops Should you experience hum or buzz caused by ground loops, check first
that each piece of equipment has its own separate path to ground. If so, operate ground lift switches
on connected equipment in accordance with the instruction manuals. Alternatively disconnect the
cable screen at one end, usually the destination end. This breaks the offending loop while still
maintaining the signal shielding down the length of the cable.
• Use low impedance microphones and line level equipment rated at 200 ohms or less to reduce
susceptibility to interference. The console outputs are designed to operate at very low impedance to
minimise interference problems.
• Use balanced connections for the microphone and main outputs as these provide further immunity
by cancelling out interference that may be picked up on long cable runs.
• Route cables to avoid interference To avoid interference pickup keep audio cables away from
mains power units and cables, thyristor dimmer units and computer equipment. Where this cannot be
avoided, cross the cables at right angles to minimise interference.
• Use good quality cables and connectors and check for correct wiring and reliable solder joints. Use
professional grade short cables to connect your turntables to the console RIAA inputs. Allow sufficient
cable loop to prevent damage through stretching.
