Recommendations for installation
The power supply is designed for 19" rack-mounting and will occupy 2 RU of rack space. If
necessary remove the rubber feet. For free-standing operation the rubber feet may be fitted.
As with any other power supply that contains a large mains voltage transformer, it is preferable
to provide a degree of physical isolation of the unit from other electronic equipment, particularly
that which carries low level audio signals, to avoid any possible hum pick-up. For this reason,
the unit is provided with a long (5 metres) cable to enable it to be positioned away from the
m ixing console.
For the same reason,
adjacent to signal processing equipment. Due to the built-in fan there is no need of special
cooling arrangements. Nevertheless, ventilation openings may not be blocked.
Finally, some consideration should be given to the earthing arrangement of the system.
The console chassis is earthed through the mains earth, via the power supply.
When rack-mounting, care should be taken to avoid any possible ground-loops in the system
which would introduce audible hum to otherwise clean audio signals. Ground loops may occur
where signal processing equipment patched to the console, has it's common signal earth to the
equipment chassis. The ground loop is formed if this chassis and the EPS1200 chassis
are in electrical contact (eg through common fixing rails they share in the rack).
This situation can easily be avoided with the built-in ground-lift switch on the front of
the EPS1200 unit. Attention: W ith the ground-lift switch activated, the cassis of the console is
not directly earthed to the mains earth, except the console is connected in addition with it`s own
power cable to the mains!
