User manual VINCENT SP-T800

[. . . ] 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. [. . . ] 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") 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-T800 provides for one or two loudspeakers. 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-T800. 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 "RCA" should be chosen. If the preamplifier is connected with an XLR cable, then the setting "XLR" is the correct one. the selected audio input connector must be interconnected to the output connector ("PRE OUTPUT" or "OUTPUT") of a preamplifier. This main amplifier cannot generate the switching signal for other components on its own!A theoretically infinite number of devices may be served with the switch impulses from a transmitting device. To this end, on most devices one of the two "POWER CONTROL" connectors may be used as a signal input and the other as a signal output. This method of passing on the signal via the devices' inputs and outputs and of thereby chaining them is also known as "daisy chaining". Many devices which can be controlled by a switching signal (not preamplifiers or integrated amplifiers), have two terminals which do not differentiate between input and output. In this case either of the two can be selected. Even some devices that transmit the switch signal (preamplifiers and integrated preamplifiers) lack this marking. In this case it may be assumed that they both are signal outputs. "POWER CONTROL" sockets of preamplifiers or integrated amplifiers must not be interconnected! [. . . ] If the power control function is not desired, remove all the cables from the "POWER CONTROL" connectors (4). The unit cannot be switched off Symptom No sound although the unit is ready for use Possible Cause Deactivate the MUTE function of the preamplifier after, as a precaution, reducing its volume level. The output of the speaker (A or B) you want to use has not been activated. After, as a precaution, reducing the volume level at the preamplifier, press the "SPEAKER A/B" button (2) associated to the speaker output used, so that the LED next to the key is illuminated.
