Precautions and Safety Instructions
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 brush is ideal. Use only
water or ethyl alcohol to clean the trim and scribble strips. Other solvents may cause
damage to paint or plastic parts.
Avoid using the console close to strong sources of electromagnetic radiation (e.g.
video monitors, highpower electric cabling): this may cause degradation of the audio
quality due to induced voltages in connecting leads and chassis. For the same
reason, always site the power supply away from the unit.
Caution!
In all cases, refer servicing to qualified personnel.
Handling and Transport
The console is supplied in a wooden crate. If it is necessary to move it any distance
after installation it is recommended that this packing is used to protect it. Be sure
to disconnect all cabling before moving. If the console is to be regularly moved we
recommend that it is installed in a foamlined flightcase. At all times avoid applying
excessive force to any knobs, switches or connectors.
Power Supplies & cables
Always make sure that the power supply unit (PSU) has been set to the same voltage
as the mains supply
Always use the power supply and cable supplied with the mixer: the use of
alternative supplies may cause damage and voids the warranty; the extension of
power cables may result in malfunction of the mixing console.
Warning!
Always switch the power supply off before connecting or disconnecting the
mixer power cable, removing of installing modules, and servicing. In the event
of an electrical storm, or large mains voltage fluctuations, immediately switch
off the PSU and unplug from the mains.
Always ensure that you use the correct PSU for your mixer. The DC2020 uses a
APS500A power supply.
Signal Levels
It is important to supply the correct input levels to the console, otherwise signalto
noise ratio or distortion performance may be degraded; and in extreme cases,
damage to the internal circuitry may result. Likewise, on all balanced inputs avoid
sources with large commonmode DC, AC or RF voltages, as these will reduce the
available signal range on the inputs. Note that 0dBu = 0.775V RMS.
The microphone inputs are designed for use with balanced low impedance (150 or
200 ohms) microphones.
