User manual VINCENT SP-998

[. . . ] 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. [. . . ] Your local stockist will be glad to advise you about this. This main amplifier is equipped with a mono audio input "LINE IN" (3) on which the unit awaits the preamplified signal of an audio channel (for example "PRE OUT R" or "FRONT R"). Please note: No source with a standard line level 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-998. 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 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". No source with a standard line level signal ("LINE OUT") must be connected to this input. Summarizing, you will use an RCA 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 inputs. Ensure the volume of the respective preamplifier is not set too high before switching. To avoid the necessity of switching them on and off before and after every use, many manufacturers have equipped their devices with what is known as "POWER CONTROL" circuit or "TRIGGER". This kind of remote-controlled standby circuit is used primarily for preamplifier and main amplifiers, as power amplifiers are often placed far from other devices near the speakers. To employ these functions, direct or indirect cable connections must be made between the preamplifier (or integrated amplifier) and all the devices which support this function. The "POWER CONTROL" function operates in such a way that each switching on or off of one device in the system (usually the preamplifier) automatically brings about the switching on or off of all the connected devices which support this function. Please keep in mind that all devices which respond to the power control are not disconnected from the mains network when switched off. For each connection between two devices one of those cables is needed. If the power control function is not desired, the switch signal cable must therefore be removed!You can connect one loudspeaker the usual way (via a two-core speaker cable) to the power amplifier SP998. Some music enthusiasts may want to connect the speaker in "bi-wiring". For each speaker the unit provides two speaker terminals (2x positive + and 2x negative ­). [. . . ] 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. If the power control function is not desired, remove all the cables from the "POWER CONTROL" connectors (5). The unit cannot be switched off No sound, appliance is switched on (the LED (2) on the front of the device is lit) The setting of the switch "XLR/RCA" in the connector area "LINE IN" is not correct.
