User manual VINCENT SP-995

[. . . ] 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. [. . . ] xLR connections Please note that European and US-American XLR signal assignments for the connector pins are different. 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 Cable connections Make sure that all plugs fit tightly. Inadequate connections can cause noise interference, failures and malfunctions. To make the most of the components' sound potential, only high quality loudspeakers and connecting cables, for example Vincent cables, should be used. Your local stockist will be glad to advise you about this. This main amplifier is equipped with a mono audio input "LINE IN" (6) on which the unit awaits the preamplified signal of an audio channel (for example "PRE OUT R" or "Front R"). This is the audio information that the SP-995 provides for one or two loudspeakers. If the "POWER CONTROL" cable is connected to this device, the second jack connector serves to pass on the switch signal (for example to the main amplifier of the other channel) or it remains free. This main amplifier cannot generate the switching signal for other components on its own! Please note: No source with a standard line level signal ("LINE OUT") must be connected to this input. Which the preamplifier can be connected as desired by means of either the RCA or XLR connection on the SP-995. If your preamplifier offers both options, XLR is preferable. Only one of the two connectors may be used at any given time. The setting of the switch "XLR/RCA" determines which connector is currently used as the input. If the preamplifier is connected with an RCA cable, then the setting "XLR IN" (4) must be switched off (LED is not lit). If the preamplifier is connected with an XLR cable, then the setting "XLR IN" must be switched on (LED is lit). connect the selected audio input connector to the output connector ("PRE OUTPUT" or "OUTPUT") of a preamplifier. If the SP-995 is to supply one channel of a stereo system, connect the input connector of the SP995 with a preamplifier output socket that is usually labelled "PRE OUT R" or "PRE OUT L". Summarizing, you will use an RCA connection and/or an XLR connection: Both "LINE IN" inputs can be connected to preamplifiers at the same time and in this way it is possible to connect two preamplifiers simultaneously and toggle between the desired "LINE IN" modes. Ensure the volume of the respective preamplifier is not set too high before switching on. [. . . ] Symptom Unit does not work after pressing the power button Mains cable is not connected to a suitable mains wall outlet. Mains cable has not been firmly inserted into wall power socket and the device's socket (8). If necessary, exchange it with a suitable mains cable and push its plug firmly into wall socket and the device's power connector. Disconnect the "POWER CONTROL" cable or turn on the unit outputting the signal. [. . . ]
