User manual VINCENT SP-996

[. . . ] Please follow the security precautions, though some of those things may seem obvious. In the appendix to this manual you will find a glossary explaining some established technical terms. If there are open questions your audio specialist dealer will help you. He also represents your contact person in case of needed warranty service or repairs after the warranty period and is interested to hear from your experiences with Vincent products. [. . . ] You will notice a reduced sound quality if the connections are the wrong way round. Only use loudspeakers with a nominal impedance of at least 4. If you use loudspeaker cable equipped with 4mm banana plugs you are required to remove the small plastic plugs located in the connector holes of the speaker clamps when first installing this main amplifier in your system. This Vincent preamplifier uses the European system following the standard AES14-1992. the cable structure is the same in any case. As long as both the preamplifier and the power amplifier satisfy the same standard, the signal connection is correct. This is always the case if both units were made by Vincent. If two units from different standards are connected, this inverts the signal. in this case the signal assignment on one side of the connection has to be changed. Your audio specialist dealer will support you with this. Cable connections Make sure that all plugs fit tightly. The required voltage and frequency can be read on the back of the device beside the socket for the mains. If the electricity supply is appropriate, push the inlet connector of the supplied mains cable firmly into socket for the mains on the back of the device (8). Either a single pair of loudspeakers or two speaker pairs can be connected to the main amplifier SP-996. For each loudspeaker you will find two connector screws (positive + und negative ­) at the amplifier's backside. one side of the speaker cable must be attached here. Each pair of screws has a label "R" or "L" nearby to clarify to which stereo channel it belongs. at the loudspeaker connection terminal there are similar connector screws or connectors. There, the polarity of each screw (+ or ­) can be identified as well and the other side of the speaker cable associated with this speaker must be attached. Make sure only connector screws of the same polarity will be connected by each speaker cable wire: a knob marked "+" in the amplifier's terminal must be connected with a speaker's connector screw marked "+" as well. Our sketch shows all connections necessary for one pair of speakers. If a second pair of loudspeakers is intended to be used, the connector screws of the lower row must be connected in a similar fashion to the additional speakers' input connectors. [. . . ] If necessary, exchange it with a suitable mains cable and push its plug firmly into wall socket and the device's power connector. If the power control function is not desired, remove all the cables from the "POWER CONTROL" connectors. The unit cannot be switched off No sound on both channels although the unit is ready for use (LED (3) is lit) The setting of the toggle switch "XLR/RCA" (4) on the front panel is not correct. The cable connections are not tight, the connectors are dirty or a cable is defective. [. . . ]
