Page 2: Introduction
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. -
Page 3: Design Innovation
Cursa 3 manual.qxd 10/12/2002 15:23 Page 3 Design Innovation In common with all Rega products, the Cursa 3 pre-amplifier has been designed without compromise. Our time and money has been spent on developing the unique circuit design and sourcing unusually high quality components. -
Page 4: Installation
Never stack other hi-fi components on top of the amplifier. Due to the layout of Rega’s amplifier circuit designs, they are virtually insusceptible to electro magnetic interference, and by virtue of the extruded aluminium case, emit practically no electro magnetic radiation. -
Page 5: Dc Protection
Cursa 3 manual.qxd 10/12/2002 15:23 Page 5 DC Protection The amplifier has a circuit which protects the power amplifier connected to the pre-amplifier output, from direct current in the event of a major failure of the system. The use of this sophisticated DC protection circuit in conjunction with a servo correction stage, (on all line inputs) allows the amount of capacitors in the signal path to be kept at a minimum. -
Page 6: Pre-Amp Outputs
The 2 parallel pre-amp outputs use RCA type (phono) connectors. The output is at standard line level of 0.83V, but your Rega dealer will be able to modify the output level to accomodate a range of power amplifiers. See specifications on page 13 for further details. -
Page 7: Input Connection
Input Connections All inputs and outputs are made via RCA (phono) type connectors. The sockets on the Rega amplifiers are clearly marked red and white. Right: always the lower row and marked in RED. Left: always the upper row and marked in WHITE. -
Page 8: Phono Input
15. Earthing of Tonearm 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. -
Page 9: Line Inputs
Cursa 3 manual.qxd 10/12/2002 15:23 Page 9 Line Inputs The line inputs enable the connection of additional sources, such as a second tape machine, tuner, or video recorder for use with an Audio Visual system. Tape Input/Output Almost any tape machine can be used with your amplifier, including compact cassette, video cassette, reel to reel, DAT, and DCC. -

The volume control has a resolution of 1dB per step, giving a total range of 80 steps over the available gain or volume range of 80dB.

Page 12: Input Selection
The Cursa 3 features an optional remote control. This has additional buttons not used by the by the Cursa 3, but all funtions offered on the pre-amplifier can be performed using the remote control. -
Page 13: Output Level And Gain Change
Gain range or level 3 gain = 15dB Any adjustments made to the power amp link switch and gain must be carried out by an authorised Rega dealer. If work is carried out by any person other than a Rega dealer it will invalidate your warranty. -
