User manual VINCENT SA-93 PLUS

[. . . ] 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. [. . . ] AC power connector and fuse holder To establish the power supply, connect the plugs of the power cable to the device and to a 230V AC wall outlet. The small plastic housing beneath the plug opening holds the fuse. Point the diode side of the remote set to the front panel of the pre-amplifier, make sure there are no objects between the remote set and the device. Keep the distance between remote set and device less than 7 meters. Do not point from an angle greater than 30 degrees from the middle axis. Change the batteries when the distance of reliable operation is shortening. The cells must be inserted respecting the correct polarity as seen on the plan inside the battery housing. For longlife operation do not mix old batteries and new ones and use the same battery type (for example alcaline). Some battery cells are rechargable, some are not. Refer to the details written on the cell surface. remove batteries when not using the remote control for an extended period. Used batteries are hazardous waste and must be disposed of according to local regulations. The cover plate is being held magnetically, a little pull from underneath the notch in the case of the remote set will do. Remove used cells and insert new ones as seen on the scheme inside. Gain: Push button for -10dB attenuation of Pre Out signal Should only be activated for main amplifiers with high sensitivity. Bal L and Bal R: Push buttons for volume balance Set the volume difference between right and left channel if needed Input selection push buttons To select the input source audible from your Hi-Fi system. Level und Level : Volume buttons Control the level of the output signal and thus the volume of loudspeakers and headphones in your system. Your loudspeakers will be connected to the main amplifier, your audio sources to the pre-amplifier. To achieve best performance only quality interconnection cables as produced by Vincent should be utilized. Connections Input connectors for audio source devices and output connectors for the main amplifier are mechanically identical RCA jacks that must not be interchanged!If both connected devices use the same type, the signal connection is correct (Always, if both devices have been produced by Vincent). For the connection of two devices using the opposite system a different cable must be used to avoid inverting of both channel signals. [. . . ] If it is activated, ground potential of the chassis and the protective ground wire are being separated from the central signal ground point. The protective ground wire keeps its function. Sometimes this helps prevent noise caused by errors in grounding. If the problem occurs and cannot be solved by youself your audio specialist dealer will help you Symptom No function after switching on Possible reason Power cable not connected to an active wall outlet Power cable not connected tight to wall outlet or chassis jack Power cable defective Blown Fuse Connect the power cable to an active wall outlet Press the power plugs tight into the wall outlet and the device's power connector Change against an adequate power cable Change fuse Carefully increase the volume Revise your selection Check and correct the connections Volume setting too low Not the desired input channel has been chosen You did not (or not correctly) connect the output of the source device oder not to the desired input connector of the pre-amplifier Source device does not give output signal You did not (or not correctly) connect the main amplifier, or switched it off Speaker cable connections to the main amplifier are not correct or speakercable damaged One of the speaker cables has not or not correctly been connected, or defective speaker cable One of the signal cables between preamplifier and main amplifier has not or not correctly been connected, or defective signal cable One of the signal cables between Source and pre-amplifier has not or not correctly been connected, or defective signal cable The balance setting is extreme Check speaker cables and their connections on both sides Check signal cables and their connections on both sides Check signal cables and their connections on both sides Correct this setting Check and replace battery cells if necessary Try and use remote set only at free line of sight inside the radius of maximum distance facing the front panel No batteries or used-up cells in the remote set Line of sight between remote set and audio device is blocked or maximum distance is exceeded or commands given from a too large angle Device switched off Low frequency humming noise audible Plugs and sockets are built from a middle pin conductor and a concentric metal cylinder mantle as the outer conductor.
