INTRODUCTION

The Plinius Model 12 Preamplifier is a continuation of the design philosophy embodied in all Plinius Amplifiers and involves the use of assymetrical circuit topology as opposed to the more normal symmetrical approach. The Model 12 is available in either Phono (M12P) or Line (M12L) variations. The M12L can be upgraded to M12P quite readily by the addition of the M12 Phono Circuit Board.

The Model12 uses an "on board" power supply which consists of a large value toroidal transformer and a tightly regulated initial power supply system. The main power supply occupies a large circuit board located along with the toroidal transformer in a cabinet beneath the main circuit board and is isolated by an aluminium and Custom Wood shelf. This shelf is a sandwich construction 10mm thick and provides a high mass low resonance structure for the main circuit board.

The M12 Chassis is constructed in the main from10mm aluminium with a 12mm aluminium front fascia. We have designed the chassis to be as resonant free as possible and this has great bearing on the 'sound' of the preamplifier.

Each stage of amplification has its own individual regulator further adding to the ability of the M12 to recreate the full dynamic range possible with today's source material.

The Phono Stage consists of a FET amplifier without overall feedback, in a design similar to a tube circuit, followed by the high frequency equalisation. This in turn is followed by an active feedback low frequency stage.

Although the Model12 was initially designed to provide superb results from Phono source material, the high level circuits have been optimised for CD and other popular sources.

Every component used within the Model12 has been chosen for sonic excellence and all signal cable is by Siltech. All switching is done by high quality silver contact relays and the potentiometers have been selected from Audiophile quality types. The two selector switches on the front panel only activate the relays. They do not carry any audio signals.

The volume control is an ALPS type and will accurately convey the source signals to the high level amplification stages.
