User manual VINCENT SV-238MK

[. . . ] 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. [. . . ] At the source device you can recognize it by the three-pin XLR-type of the output jack. Leave the XLR input of your preamplifier open if none of your audio sources uses this. You only need the sockets "PRE OUTPUT" (9) if you want to use one or more separate main amplifier(s) to supply additional loudspeakers. This makes sense if you intend to use two more loudspeakers for stereo music playback, for example in a separate zone (another room of your home). These loudspeakers are then connected to the speaker outputs of the additional amplifier(s). The amplifier output connections "PRE OUTPUT" (9) must be connected with the input connectors of the main amplifier, in most cases labelled "INPUT", "POWER AMP IN" or "MAIN INPUT". Both outputs reproduce the same stereo music signal of the currently selected source. Instead of the stereo main amplifier used here two mono main amplifiers can be utilized. 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 power amplifiers. Particularly for preamplifiers and main amplifiers this kind of remote standby control is utilized, 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 you don't wish to use this function or if the other components do not support it, all you have to do is leave out these cable connections. The SV-238MK is equipped with two output connectors for the power control. Here, the switching signal generated by the amplifier is available for other components of the system. Two HiFi components that are able to react to the power control signal can be connected directly to the amplifier's power control outputs (7). If more than two devices, which can be controlled, are to be connected, then it is necessary to make the power control connection between the amplifier and these further devices through the outputs of the two devices which are connected directly. For that reason, every HiFi component that accepts power control signals is also equipped with a power control output. Thus, in theory it is possible to provide an infinite number of HiFi components with the power control signal. [. . . ] No sound on both channels although the unit is ready for use (front panel display (2) is functional) One of the audio settings of a connected DVD player (analogue/digital) has not been correctly selected. One of the signal cables between audio source and amplifier inputs has not yet been plugged in or is defective. The cable connections are not tight, the connectors are dirty or a cable is defective. A record player has been connected to a line level input without using a phono preamplifier. [. . . ]
