INTRODUCTION

CONGRATULATIONS on your decision to become the proud owner of this

PLINIUS Tautoro Preamplifier.

This manual has been prepared to help you understand the operation of your

preamplifier, and to provide information about its design and the variety of ways it may

be used.

We have designed and manufactured this preamplifier to reproduce your favourite

music faithfully and accurately. With a little care and a full understanding of the

operating recommendations in this manual, your PLINIUS Tautoro Preamplifier will

provide years of high-quality, trouble-free performance.

IMPORTANT: PLEASE TAKE THE TIME TO READ THIS MANUAL

THOROUGHLY BEFORE USING YOUR PREAMPLIFIER.

DESIGN PHILOSOPHY

From a distance you can see that the design of the Plinius products is more than

an applied styling exercise to the front panel. We have started from the ground up

to produce a casing for our electronics that is unrivalled in its physical strength and

visual simplicity.

Wherever possible we have reduced the number of parts needed and then invested

massively in refining and producing the remaining parts to the highest quality

achievable with state of the art computer controlled machines allied with expert

craftsman. Examples of this approach include the hydraulically formed corners on

the amplifiers giving much greater strength and the one piece housing for the remote

control that looks, feels and genuinely is robust.

As with music that you are not familiar with, truly innovative new designs can take time

to understand and enjoy. How often have you heard music that you were first unsure

of, that over repeated listening, has become a firm favourite.

Our designs are fundamentally different to many other companies, and we hope that

you will take the time to explore their unique character and qualities because we have

not made them different simply to be different. We genuinely believe that their visual

and tactile qualities do improve the experience of listening to music and that is our

design goal!

UNPACKING

Open the box from the top and remove the accessories from the foam end caps.

You may now proceed to lift the unit from the box, Once the unit is removed you

can proceed with the removal of the foam end caps. These caps are designed to fit

on the front and back of the unit for maximum protection. Retain the packaging for

future transportation of the Tautoro.

PLACEMENT & VENTILATION

Your PLINIUS Tautoro may operate at a moderately high temperature, especially during

extended listening sessions. The ideal location is upon a rigid stand, away from direct

contact with any temperature sensitive materials, furniture or deep pile carpets. Ventilation

through and around the ampliﬁer should also be kept unimpeded. Please ensure that the

heat vents (slots in the base and lid) are not covered or restricted in any way.

The PLINIUS Tautoro design incorporates a very high level of mechanical decoupling of the

input and output. It can however still be inﬂuenced by acoustical feedback in the operating

environment. The use of acoustic cones or a suitably spiked ampliﬁer stand or table may

further enhance the performance of this preampliﬁer. Consult your Plinius dealer for further

advice if required.

PRECAUTIONS

PLEASE TAKE SPECIAL NOTE OF THE FOLLOWING PRECAUTIONS BEFORE

OPERATING YOUR NEW PREAMPLIFIER.

This preamplifier operates at hazardous voltage levels. We recommend that any

work requiring removal of the lid be referred to a suitably qualified and experienced

service technician.

DO NOT attempt to connect any input of this preamplifier to its own outputs.

DO NOT earth any output terminal or connect any of these terminals together

without following the instructions in this manual or seeking qualified assistance.

DO NOT place this preamplifier in any position where liquids or any foreign material

may accidentally enter it.

DO NOT connect any voltage source, short circuit, earth/ground or appliance (other

than suitable audio power amplifiers) to the preamplifier output terminals.

DO NOT connect any voltage source, short circuit, earth/ground or appliance (other

than suitable audio source components) to the preamplifier input terminals.

PREAMPLIFIER FEATURES

– FRONT PANEL

ABOVE: Tautoro front panel layout

DISPLAY LED

An LED on the front panel indicates that the power is on. When ﬁrst switched on, the unit

will go into standby and the display LED will vary in brightness. When the unit is taken out

of standby and is ready for use, the LED will remain lit. Whenever mute or a remote volume

button is pressed, the LED will dim.

SOURCE SELECTION BUTTONS

The buttons on the front panel allow selection of any of the ﬁve different inputs available on

the rear panel. This selection is fed to the outputs of the preampliﬁer.

SOURCE DISPLAY LEDS

These small white LEDs communicate the current source selection.

NOTE: the Phono/Line 1 input displays the current installed option relating to this input. If you

have a Tautoro with a phono option installed, the phono LED will light to indicate this. If the

phono option is not installed, the Line 1 LED will light.

PHASE DISPLAY LED

This small white LED is ON when the phase of the input signal to the preamplifier is

inverted 180 degrees. This option is selected using the remote control.

HT BYPASS LED

This small white LED is ON when the current source selection is the HT Bypass Input.

This input can by selected using the remote control, or when the unit is taken out of

standby via the remote trigger input.

HEADPHONE SOCKET

The socket below the volume control is for connection to a set of suitable hi-fidelity

headphones with 6.35mm (1/4 inch) jack.

VOLUME CONTROL KNOB

The volume control is a motorised unit that will accurately convey the selected source

signal to the line stage of the PLINIUS Tautoro. When using the remote control to

alter the volume level, briefly press the button to make small adjustments, or hold the

button down to continuously adjust the volume.

PREAMPLIFIER FEATURES

– REAR PANEL

This panel incorporates all the terminals for connecting the input signals from your

CD player, tuner, etc, the outputs to the power amp and the mains supply.

Please remember that your PLINIUS Tautoro Preamplifier is a high quality electronic

instrument. Be sure that you read and fully understand the section “Installation and

Operation” before you make any connection to this Preamplifier.

ABOVE: Tautoro rear panel layout

INPUT TERMINALS

The input terminals of your PLINIUS Tautoro Preamplifier are easily accessible along

the rear panel.

RCA INPUTS LEFT & RIGHT: These standard RCA terminals are for use with

unbalanced signals from any line level audio component such as a compact disc

player, tuner, surround processor, VCR, etc.

XLR BALANCED INPUTS LEFT & RIGHT: Also included are balanced XLR inputs for use

with any Line Level component that features Balanced XLR outputs. Balanced signals

are carried via a three way cable that connects all three pins at each end of the

interconnect cable.

The XLR input pin configuration used in all Plinius products is as follows:

PIN 1 to GND

PIN 2 to +Signal

PIN 3 to -Signal

NOTE: Because of the way balanced XLR inputs are configured it is not possible to

connect both XLR and RCA at the same time.

INPUT SELECT SWITCH

This switch located between the RCA and XLR connectors is used to select the pair

of input sockets required, as described above. Up selects the RCA input connections,

while down select XLR input for each individual source.

HT BYPASS INPUT

This input is for use speciﬁcally with home theatre processors. In some circumstances

you may wish to use the power ampliﬁer and speakers that the Tautoro is connected to

as the front two channels of a surround or home theatre environment. The processor

input can be used for this purpose, as any signal connected to the processor inputs

can be sent directly to the power ampliﬁer bypassing the Tautoro entirely.

OUTPUT TERMINALS

Connections for power ampliﬁers are provided on the rear panel. Connections are

available for both single ended RCA and balanced XLR cables. Note that the only time

the outputs aren’t ‘live’ is when the preampliﬁer is in mute or standby. The XLR output

pin conﬁguration used in all Plinius product is:

PIN 1 to GND

PIN 2 to +Signal

PIN 3 to –Signal

NOTE: Because of the way balanced XLR outputs are configured it is not possible to

connect both XLR and RCA at the same time.

LINE OUT

These RCA outputs are situated next to main outputs and are provided to interface to

line level recording devices for archiving, or transferring to portable media. The outputs

are always live with the signal of whichever source is selected at the time of recording.

MAINS SWITCH

The heavy-duty rocker switch to the right of the panel turns the Mains/Line Power to the

ampliﬁer ON or OFF. The ampliﬁer draws a moderately high current when switched on,

so it is not good practice to rapidly turn the Mains switch on and off repeatedly.

MAINS POWER CORD IEC SOCKET

This connector is where the mains supply cable from your wall connects to the

preamplifier. A fuse holder is mounted within this connection, and it holds a mains

fuse to provide surge and overload protection for your preamplifier.

REMOTE TRIGGER INPUT SOCKET

In order to integrate more effectively into a home theatre system, the PLINIUS

Tautoro has a remote trigger input socket fitted to the rear panel. By connecting

a processor with a remote trigger signal to this socket, the Tautoro can be put in

and out of standby by the processor to which it is connected. When in standby the

amplifier draws less current and will operate at minimum temperature. This may be of

advantage in a multi-amplifier and/or remote installations. When taken out of standby,

the unit will default to ‘HT Bypass’ mode.

REMOTE TRIGGER OUTPUT SOCKET

The Tautoro also features a remote trigger output socket fitted to the rear panel. By

connecting this trigger output to the power amplifier, the entire system can be put in

and out of standby by the processor.
