SLP-2002 USERS MANUAL SLP-2002 Stereo Balanced Vacuum Tube Preamplifier Fully Balanced Vacuum Tube Line Stage Circuit Design with Cinema Bypass and Remote Volume Control CARY AUDIO DESIGN 1020 GOODWORTH DRIVE APEX, NORTH CAROLINA 27539 www.hifiengine.com SLP-2002 USERS MANUAL Congratulations Cary Audiophile! All of us at Cary Audio thank you for buying an SLP-2002 preamplifier for your home audio system. This design has many innovative features to offer ease of use and superb reproduction of your favorite music. This preamplifier includes fully balanced vacuum tube circuitry with dual triode 6922 and 5814 tubes. The remote volume control uses an Alps four gang motorized volume potentiometer, chosen for both its intrinsic sound quality and its remote control convenience. We have XLR balanced or RCA unbalanced connections for the Cinema bypass and RCA or XLR inputs for the CD player and the main preamplifier outputs. The circuit uses five fully regulated power supplies. Proper operation of the preamplifier power supply circuits is confirmed by red or green LED's that are mounted on the power supply PCB board, visible through perforations in the top panel. This is our first balanced circuit preamplifier. As such, we felt we should offer a new way to mix stereo and home theater surround sound systems together. The Cinema bypass input allows this to happen. Connect the main Left and Right outputs from your home theater processor to the Cinema bypass inputs. You can have musical, superb reproduction of your two-channel source material or surround sound from your processor in this way. Connect your CD player to the SLP-2002 for 2 channel stereo playback. We naturally suggest using a Cary Cinema P 8 surround processor due its XLR analog bypass capability for two channel listening! The Cinema Bypass input will pass a signal when the SLP-2002 preamplifier is On or Off, exactly as its' name implies. For audiophiles with balanced design CD players and power amplifiers, the balanced CD input on the SLP-2002 allows you to have a balanced system, from the input source to the power amplifier. Balanced cables offer excellent shielding from external noise sources, like radio frequency (RFI) interference. In systems where very long runs of cable are needed, balanced operation is the best way to wire a system. Both the CD- 303/200 and CD-306/200 offer balanced XLR analog outputs. In extensive listening tests we have come to admire the sound reproduction capabilities of the 6922 tube. We use it as a driver stage tube in our V-12i and Rocket 88 power amplifiers. Using the 6922 driver and 5814 buffer stage has the added benefit of creating a non-inverting preamplifier design. (6H30, 6CG7 or 6FQ7 tubes could be substituted for the 6922 tubes or 12AU7 tubes for 5814 tubes if you desire.) We hope you find the
