General Precautions Avoid storing or using the mixing console in conditions of excessive heat or cold, or in positions where it is likely to be subject to vibration, dust or moisture. Do not use any liquids to clean the fascia of the unit: a soft dry cloth is ideal. Avoid using the console close to strong sources of electromagnetic radiation (e.g. video monitors, high-power electric cabling): this may cause degradation of the audio quality due to induced voltages in connecting leads and chassis.

Initial Wiring Considerations For optimum performance, it is essential for the earthing system to be clean and noise free, as all signals are referenced to this earth. A central point should be decided on for the main earth point system, and all earths should be 'star fed' from this point. It is common electrical practice to `daisy chain' the earths to all electrical outlets but this method is unsuitable for audio installations. The preferred method is to run an individual earth wire from each o

Points to Remember In all cases, use good quality twin screened audio cable. Check for instability at the output. Always connect both conductors at both ends, and ensure that the screen is only connected at one end. Do not disconnect the mains earth from each piece of equipment. This is needed to provide both safety and screen returns to the system star point. Equipment which has balanced inputs and outputs may need to be electrically isolated from the equipment rack and/or other equipment, to a
