Precautions and Safety Ins tructions

General Precautions

Caution!

Handling and Transport

Power Supplies & cables

Avoid storin g or using the mixing console in condit ions of excessive heat or cold , or in positions wh ere it is like ly to be subjec t to vibr ation, dust or mo isture . 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 monit ors, highpo wer el ectric c abling ): this may cause degrada tion of the aud io quality due to induc ed voltages in conne cting leads and chassis. For the same reason, always site the power supply awa y from th e unit.

In all cases, refer servicing to qualified personn el.

The console is supplied in a strong ca rt on. If it is necessar y to move it any dista nc e after instal lation it is recomme nded that this pac king 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.

Always make sure t hat the powe r sup ply un it (PSU) has b een set to the same vo ltag e as the mains suppl y

Signal Levels

Warning!

Always use the power supply a nd 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 malfunc ti on of the mixi ng consol e.

Always switch the power supply off before connecting or disconnectin g the mixer power cabl e, removi ng of install ing modules, and servicing . In the event of an electrical storm, or large mains voltag e fluctu atio n s, immed i ately sw itch off the PSU an d unplug from the mains.

Always ensure that you use the corre ct PSU for you r mixer.

It is important to supply the correct input levels to the console, otherwise signal to noise ra tio or distort ion p erforma nce m ay be de graded; and in e xtreme case s, dam age to the internal circuitry may result. Likewise, on all balanced inputs avoid sources with large c om mo nm ode DC, AC or RF volt ag es, as the se wi ll re duc e the a va ila bl e signal ran ge o n the inputs. Note th at 0dBu = 0.775V RMS.

Refer to the Speci fic a ti ons sec t ion for deta i ls of in put and outp ut lev el s.
