CONTENTS INTRODUCTION FEATURES AND TECHNOLOGY INSTALLATION CONNECTIVITY LOUDSPEAKER CONNECTIONS IN USE INPUT SELECTION MUTE REMOTE CONTROL TECHNICAL SPECIFICATION TROUBLESHOOTING OWNERS LOG 4 6 5 7 INTRODUCTION FEATURES AND TECHNOLOGY Thank you for purchasing the Brio R the latest version of Rega s best selling amplifier Housed in a brand new case the Brio R 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 R 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 150 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 Uther notable improvements include the input switches relays and rotary volume control The input relays are i
4. ING Power ON Logo illuminated but no output Is the amplifier connected to the desired input and the correct input selected Correct the fault Are the speakers connected Correct the fault correctly to the amplifier Yes Is the volume set to the minimum No Correct the fault Is the CD player selected with no disc in the machine Correct the fault Contact your Rega dealer TROUBLESHOOTING Power sound from one speaker only Are the connections between the Correct the fault by plugging them in If the speakers and the amplifier secure wires are loose or not correctly soldered and functioning correctly contact your Rega dealer Check the source component for faults Swap the output leads and check to see if the fault swaps over Are both channels of the speaker connected and working properly Are the cartridge connections at There may be a fault in the amplifier the head shell functioning Check speaker chain Swap speaker cables cartridge tags Does the fault swap channels The speaker is at fault Contact your Rega dealer 12 The source is at fault The amplifier or speaker cables are at fault TROUBLESHOOTING Loud hum through both speakers when Phono is selected Has your tonearm a seperate earth connection Connect as described on page of this manual Is the amplifier situated directly below the cartridge
5. loudspeakers Rega recommends using loudspeakers with a nominal impedance of 84 It is possible to run speakers as low as 41 however such units may cause the case to exceed 40 C above the ambient temperature Top row RED and BLACK lett speaker Bottom row RED and BLACK right speaker IN USE Switch the Brio R 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 SELECTION To change between inputs simply press the button marked input to cycle through from to 9 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 REMOTE CONTROL The Brio R is supplied with a dedicated remote control handset which allows you to select inputs through 5 mute the unit and adjust the volume Batteries included 2 x AAA Alkaline ae 7 he gt gt OR RC Brio R SPECIFICATIONS Input sensitivities for rated output level Inpu
6. n 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 R 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 direct contact between the microcontroller and the signal path as the microcontroller controls the relays and volume control motor is using control voltages During the Brio R 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 part of the phono frequency response The output amplifier is capable of driving awkward loads as low as 1 70 below this the amplitier is protected against shorted speakers and reactive loads The power supply uses a low noise generously rated toroidal transtormer and 10 000pF 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 obs
