GROUND LIFT SWITCH

The M12 is fitted with a switch on the rear panel adjacent to the Earth Terminal. This is to allow

the Signal Ground to be either connected to the Chassis Ground or to 'float' above Chassis

Ground.

On some Amplifiers an earth loop or hum can develop if both Signal Grounds are connected to

Chassis Ground. Due to the unique Input Selector arrangement, Plinius SA series Amplifiers

require the driving preamplifier to have the Signal Ground at Chassis Ground for optimum

performance.

SERVICING.

If the Top or bottom covers of the Model 12 Preamplifier are taken off for any reason, remove the

mains Supply Plug first. The Voltages present on the circuit board could be harmful.

In the unlikely event that your Model 12 should require any service please take it firstly to your

Dealer in its original packaging. He will then determine if the unit should be returned to the

factory. Your Plinius Dealer has a good understanding of our Amplifiers and will be able to

advise on any further installation requirements.

CLEANING.

A damp cloth is all that is required to remove dust and finger marks from the Model 12's anodised

surface.
