User manual VINCENT SP-997

[. . . ] 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. [. . . ] Make sure that bare loudspeaker wires are never able to come into contact with each other or with the metal on the back of the housing. Ensure that bare loudspeaker wires are never able to come into contact with each other or with the metal on the back of the housing. Make sure that the positive and negative loudspeaker wires are connected correctly. You will notice a reduced sound quality if the connections are the wrong way round. When using loudspeaker cable with 4 mm banana plugs the factory security plugs in the speaker clamps have to be removed prior first use. 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. This main amplifier is equipped with a mono audio input "LINE IN" on which the unit awaits the preamplified signal of one audio channel (for example "PRE OUT R", CENTER or "FRONT L"). Please note: No source with a standard line level output signal ("LINE OUT") must be connected to this input. This audio input is equipped with two connectors with which the preamplifier can be connected as desired by means of either the RCA or XLR connection on the SP-997. 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 switch "XLR/RCA" must be set to "RCA". If the preamplifier is connected with an XLR cable, then the switch "XLR/RCA" (3) must be set to "XLR". connect the selected audio input connector of the SP-997 to the output connector (example: "PRE OUTPUT R" , "PRE OUTPUT REAR R" or "OUTPUT R") of a preamplifier. connect a Power Control socket (named "POWER CONTROL OUTPUT" or "TRIGGER OUTPUT") of the controlling or relaying unit with one of the POWER CONTROL sockets. 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!In this way this main amplifier can respond to the signal of a different unit and relay the signal to further components of a system, if required. All other HiFi components that accept POWER CONTROL signals are equipped with one POWER CONTROL input as well as one POWER CONTROL output in the same fashion. Thus, in theory it is possible to provide an infinite number of HiFi components with the POWER CONTROL signal. This approach, to loop a signal through a chain of components, is commonly referred to as "daisy chaining". Attention: Many devices which can be controlled by a switching signal (not preamplifiers or integrated amplifiers), have two connectors which do not differentiate between input and output. [. . . ] If the problem occurs and cannot be solved by yourself your audio specialist dealer will help you. Symptom Unit does not work after pressing the power button Possible Cause 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 (7). If necessary, exchange it with a suitable mains cable and push its plug firmly into wall socket and the device's power connector. [. . . ]
