Introduction
Your REGA amplifier has been designed to reproduce music
effectively and easily.
The Brio3has been built to Rega's discriminating standards of
reliability and quality to ensure many years of musical enjoyment.
An amplifier's function is to boost the tiny signal generated by a
cartridge or other source so that it can drive loudspeakers. It is vital
that the amplifier achieves this without changing the signal and so
distorting the music.
We have avoided superfluous gadgets such as tone controls or a
head phone socket as they obstruct the signal path and degrade the
produced sound quality. In common with all REGA products, the
Brio3has been built using unusually high quality components and
no frills, so that you can simply switch on, sit back, and let your
amplifier speak for itself.......

Mission Statement
Rega’s philosophy is to make high quality products at sensible prices, as a means
of reproducing music as faithfully as possible. Rega is committed to the design
and development of new and existing products, both in hi-fi and other areas, that
will perpetuate Rega’s values of quality and value for money.

Installation
The Brio3will work well on most surfaces, such as a shelf or table,
provided there is sufficient air around the amplifier to prevent
overheating. To avoid magnetic interference, site the amplifier as far
away from the turntable as the tone arm lead will allow. If possible,
place it to the left of the turntable. Keep other equipment, such as
tuners, cassette decks or CD players away from the amplifier. Never
stack other hi-fi equipment on top of the amplifier.
Ventilation
The heat produced by the Brio3is dispersed to the air by the case,
particular from the base. Ensure that the case has an unobstructed
air passage around it. Never place the amplifier on carpet, rugs,
bedding, or other hi-fi equipment.

Input Connections
All the inputs and the tape outputs are made via RCA (Phono) type
connectors. The sockets on Rega amplifiers are clearly marked left
and right.
Right: always the lower row and marked in RED
Left: always the upper row and marked in WHITE
IMPORTANT: ALWAYS TURN OFF THE AMPLIFIER WHEN CHANGING LEADS
ESPECIALLY SPEAKER CABLES.
Rear Panel Connections
Earthing: Earthing is done via the Phono socket ground for Rega
turntables so a separate earth is not necessary. In the unlikely event
that your tonearm needs to be earthed to the amplifier, the grounding
tag may be connected to the case grounding screw above the input
sockets.
Phono Input
The Phono input can be used with moving magnet (MM) or HIGH
OUTPUT moving coil (MC) cartridges.

Compact Disc Input
The CD input is suitable for use with most types of CD players.
Tuner Input
The tuner input is suitable for use with most tuners.
Line Input
The Line input enables the connection of another source, such as a
second tape machine, tuner, video recorder, etc...
Tape Input/Output
Almost any tape machine can be used with the Brio3, including
compact cassette, video cassette, reel to reel, DAT and DCC.
Tape Output
This output monitors any one of the inputs selected by the input
selector.
NOTE: This function is disabled when tape input is selected.
Loudspeakers
The Brio is capable of driving all normal Hi-Fi loudspeakers with a
stated impedance of 8 ohms and above. (Most Loudspeakers are
nominally 8 ohms).

Loudspeaker Cable
We recommend using good quality cable such as our own, or similar
types made by QED or Naim. Very expensive cable claiming to use
special materials and technologies along with "solid core" or OFC
types are not recommended. Try to keep cable runs to either speaker
of similar length. Your Rega dealer will be able to make up specific
lengths of cable for you with plugs (where required) already fitted.
Never join cables together to increase their length.
Damage by shorting: Never short (i.e. touch together), the bare
ends of the speaker cable on any amplifier. However, the protection
circuit will prevent damage in the case of accidental shorting.
In Use
Switching On
The Brio is turned on by depressing the power switch on the left of
the control panel. An LED in the power switch will glow red. At turn on
an audible thump may be heard through the speakers, this is normal.
WARNING: Never switch the amplifier on with the volume control set
at or near maximum. After switching off, the LED will glow for several
seconds before fading while the remaining charge in the smoothing
capacitors is dumped.
Input Selection
The Brio3's five inputs - Tape, Line1, Tuner, CD and Phono are
selected by turning the selector knob to the required input.
