INTR DUCTI N, FEATURES AND TECHN L GY

Thank you for purchasing the Brio-

the latest version of Rega’s best

selling amplifier.

Housed in a brand new case the Brio-

draws on the pedigree of the

previous three incarnations of this model. The sonic recipe for the Brio

embodies the best in traditional audio circuits with excellent engineering

practice.

A newly designed output amplifier in the Brio-

was born after extensive

research by our engineers to develop a low source impedance emitter follower

Class A driver stage. This is based around a complementary pair of 150w

Sanken Darlington output transistors. The technical and sonic improvement

gained by the use of low impedance drivers is well known, however it can

feature high standing currents in the driver stage when using standard

transistor configurations. By combining the low impedance driver with the

Sanken Darlington transistors (with their imbedded thermal bias network

running at a lower standing current) this combination forms a complementary

emitter follower emulating Class A conditions with good thermal stability with

lower standing currents in the driver stage.

Other notable improvements include the input switches (relays) and rotary

volume control. The input relays are in the optimum position, being placed

directly between the input sockets and the amplifier input, shortening the signal

path at this critical stage.

Remote control has been added to the Brio-

for the first time without

compromising the sonic design of the amplifier. This was achieved by keeping

the remote circuit separate to the audio circuit and having its own dedicated

power supply (via a separate winding on the mains transformer). There is no

direct contact between the microcontroller and the signal path, as the

microcontroller controls the relays and volume control motor is using DC

control voltages.

During the Brio-

design process Rega reviewed the circuit and improved

the low and high current power supplies, coupling and bypass capacitors,

(where film capacitors are used throughout the signal path). The phono stage

has been improved to reflect the current improvements in the Rega Planar

turntables, where the input sensitivity has been increased along with a revision

of the sub 100Hz part of the phono frequency response.

The output amplifier is capable of driving awkward loads as low as 1.7Ω, below

this the amplifier is protected against shorted speakers and reactive loads.

The power supply uses a low noise generously rated toroidal transformer and

10,000µF smoothing capacitors that provide enough current to drive the most

awkward of loads.

We have avoided superfluous gadgets such as tone controls and headphone

sockets as they obstruct the signal path and degrade sound quality. The Rega

Ear (sold seperately) is a dedicated headphone amplifier designed specifically

for this purpose offering far greater performance than an in built socket.

The Brio-

is utilising the highest quality components and all of our

engineers’ experience to achieve the best sonic performance and ensuring it is

the most advanced and feature packed Brio to date.

INSTALLATI N

The Brio-

will work well on most surfaces, such as a shelf or table,

provided there is sufficient air around the amplifier to prevent overheating. If

using a turntable, magnetic interference can be avoided by positioning the

amplifier as far away from the cartridge as the tonearm lead will allow. ever

stack other hi-fi equipment directly on top of the amplifier. The heat produced

by the Brio-

is dispersed to the air by the case itself. Ensure that the case

has an unobstructed air passage around it. ever place it directly on fabric or

carpets.

C NNECTIVITY

All the line level inputs and the line level output are made via RCA (Phono)

connectors. The sockets on Rega amplifiers are identified as follows:

Left: Always the upper row and marked in WHITE

Right: Always the lower row and marked in RED

IMP RTANT: ALWAYS TURN FF THE AMPLIFIER WHEN CHANGING

LEADS & SPEAKER CABLES.

Rear Panel Connections

Input 1 – Phono stage for use with a turntable only.

The Phono input can be used with moving magnet (MM) or HIGH OUTPUT moving coil

(MC) cartridges.

Earthing: For Rega turntables earthing is achieved via the Phono lead ground

therefore a separate earth is not necessary. If your tonearm has a separate earth

lead it will need to be connected to the grounding nut located on the underside of

the amplifier.

Input 2-5 – Standard “Line level” Line inputs enable the connection of any

additional sources such as CD players DVD, TU ER etc. ote the record output

is disabled when input 5 is selected.

Input 5 – Record input “line level” We advise if a recording device with the

ability to monitor the recording signal is connected to the amplifier, its output

is connected to input 5 to stop possible feedback issues.

Record output For connection to any recordable device (such as a CD

recorder). The output is a ‘record signal’ as selected by the main input selector

1-4. ote the record output is disabled when input 5 is selected. This output is

not affected by the volume control.

Mains Power lead The supplied power lead should be connected to the ‘Power

in’ socket also located on the rear of the unit.

L UDSPEAKER C NNECTI NS

The Brio-

is capable of driving all normal Hi-Fi loudspeakers, Rega

recommends using loudspeakers with a nominal impedance of 8Ω. It is possible

to run speakers as low as 4Ω however such units may cause the case to exceed

40° C above the ambient temperature.

IN USE

Switch the Brio-

on by pressing the power button located on the left hand

side of the front panel above the Rega Logo. After a few seconds you will hear

a gentle click indicating the switch on relay has been released and the amplifier

is ready for use.

INPUT SELECTI N

To change between inputs simply press the button marked ‘input’ to cycle

through from 1 to 5.(This button can be held down to cycle quickly).

The selected input is highlighted by the corresponding red LED. Input selection

can also be changed via the supplied remote control handset.

MUTE

The mute function is available only via the remote control. This function mutes

the power amplifier outputs. When selected a red LED is illuminated on the

front panel, press again to deselect.

REM TE C NTR L

The Brio-

is supplied with a dedicated remote control handset which

allows you to select inputs 1 through 5, mute the unit and adjust the volume.

(Batteries included 2 x AAA Alkaline).
