Rega pre-amplifier has been designed to reproduce music effectively and easily. The Cursa 3 has been built to Rega’s discriminating standards of reliability and quality to ensure many years of musical enjoyment.
A pre-amplifier's function is to act as a control and switching unit for a variety of sources, and to boost the tiny signal generated by a cartridge, CD player, or other source to a level suitable for input into a power amplifier; which in turn boosts it to a higher level to drive the loudspeakers. It is vital that the amplifier achieves this without changing the signal, as this would distort the music. We have avoided superfluous gadgets such as tone controls or a headphone socket as they obstruct the signal path and degrade the produced sound quality.
The Rega amplifiers incorporate remarkable and innovative design ideas. For those interested in the technical details, these innovations are described more fully in this manual. Alternatively, you can simply switch on, sit back, and let your amplifier speak for itself...
