User manual VINCENT SV-129

[. . . ] 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. [. . . ] C) Put the compartment cover back on and close the battery compartment. Connect the power cable between device and power supply only after all other connections have been made. Protective caps Prior to the first installation the protective plastic caps must be removed from all the connections used at the rear of the unit. Make sure that you do not get these connections confused during installation! Make sure that bare loudspeaker wires never 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. Only use loudspeakers with a nominal impedance of at least 8 (if two pairs of loudspeakers are connected) and a nominal impedance of at least 4 (if one pair of loudspeakers is connected). Inadequate connections can cause noise interference, failures and malfunctions. Make sure that you do not mix up the analogue inputs for right and left. The RCA plugs for these are mostly colour coded as follows: red for the right channel, black or white for the left channel. - falsely Contacting the middle pin of the RCA plugs with the outer ring of the RCA chassis jack may lead to damages to the main amplifier if it is switched on!To avoid this hazard, connect or disconnect only in switched-off state and more than one minute after deactivating!Speaker cable connections The use of ready-made loudspeaker cables is recommended instead of connecting the cable's central wire (strand) directly to the terminals. To make the most of the components' sound potential, only high quality loudspeakers and connecting cables, for example Vincent cables, should be used. For maximum music enjoyment, we recommend that you connect to the "REC" jack adapter only as long as you are recording. The jack "PRE OUT" (11) is only needed when you separate amplifier for the supply of additional speakers want. This can be useful when two more speakers will be used for stereo music playback, even in another room. These speakers are then connected to the outputs of respective amplifiers. The output connectors "PRE OUT" (12) of SV-129 are connected with the input terminals of the amplifier (s), which are mostly labelled as "INPUT", "POWER AMP IN" or "MAIN INPUT". As shown here, instead of stereo power amplifier, two mono amplifiers can also be used. For each speaker you will find two speakers at the device terminals (positive + and negative -), with one side of a speaker cable connected. [. . . ] No sound, though the device is switched on and is ready (the LED "POWER" on the front panel shines) One of the audio settings of a connected DVD player (analogue / digital) is not selected properly. The speaker cables are not properly connected to the amplifier's terminals or are defective. Bring the push-button "TAPE" (8) in its switch off position You can try to use it at a different amplifier for a test. One of the signal cables between audio source and amplifier inputs has not yet been plugged in or is defective. [. . . ]
