User manual VINCENT SA-31

[. . . ] Dear Customer, we thank you for the confidence you prove in purchasing our product. It will match your high demands towards sound and manufacturing quality. Though it is understandable that you want to plug and play this product instantaneously, we encourage you to read this manual carefully before installation. It will help you in handling and operating this machine in your system and obtaining the best possible performance, even if it was installed by your dealer. [. . . ] OUTPUT: preamplifier outputs With these two pairs of connectors you can connect the preamplified stereo audio signal of the currently selected source to the power amplifier channels. AC: Power Connector To establish the power supply, connect the plugs of the power cable to the device and to a suitable wall outlet. Make sure that you do not get these connections confused during installation!Make sure that you do not mix up the analogue connectors for right and left. The RCA plugs for these are mostly colour coded as follows: red for the right channel, black or white for the left channel. To make the most of the components' sound potential, only high quality loudspeakers and connecting cables, for example Vincent cables, should be used. Contacting the middle pin of the RCA plugs with the outer ring of the RCA chassis jack may lead to damages to the main amplifier if it is switched on!To avoid this hazard, connect or disconnect only in switched-off state and more than one minute after deactivating!You can connect up to four devices with analogue stereo high level output such as a CD player in order to provide the audio signals of your input sources to the system. the output sockets on the source equipment are usually indicated by "Line Out" , "Audio Out" or "Front Out". You will find information about ways to connect source equipment in their operating manuals. The audio inputs "CD", "AV", "TAPE" and "TUNER" (9) represent electrically equivalent standard high level inputs with RCA connection. This preamplifier has two stereo preamplifier outputs with RCA connectors for the main amplifier channels. In this way it is possible to drive four loudspeakers or bi-wire/bi-amp one pair of loudspeakers. the main amplifiers supply the system's loudspeakers and the loudspeakers are connected to the outputs of these. Instead of each stereo main amplifier shown here you can alternatively use two mono main amplifiers. Connection of one pair of speakers: In this case you will need two main amplifier channels, for example one stereo main amplifier. Connect both sockets named "1" in the field "OUTPUT" with the RCA input sockets of the main amplifier channels (often marked as "INPUT" or "POWER AMP IN"). The letters "R" and "L" indicate the correct correlation. You may further use the SA-31 preamplifier output marked with "2" for a headphone amplifier. General hints: To use a record player you need a so-called phono preamplifier (also called an equaliser preamplifier), which is installed in the signal path between the record player and one of the high-level inputs. Some models of record player already include this preamplifier and can be connected directly. [. . . ] If necessary, exchange it with a suitable mains cable and push its plug firmly into wall socket and the device's power connector. No sound on both channels although the unit is ready for use (POWER LED is lit) One of the audio settings of a connected DVD player (analogue/digital) has not been correctly selected. Main amplifier(s) has/have not been connected correctly to the preamplifier, is/are switched off or is/are faulty. The speaker cables are not properly connected to the main amplifier's terminals or are defective. [. . . ]
