[. . . ] 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. [. . . ] Connect the power cable between device and power supply only after all other connections have been made. DURING INSTALLATION PLEASE OBSERVE THE FOLLOWING ADVICE: 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. MUTE Pressing this button once cuts the signals at the outputs "OUTPUT" (13) and "REC OUTPUT" (12) so that the system's loudspeakers are muted. Input selector buttons Select the input source you want to listen to with these buttons. Cable connections Make sure that all plugs fit tightly. Inadequate connections can cause noise interference, failures and malfunctions. Make sure that you do not get these connections confused during installation!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. Make sure that you do not mix up the analogue connectors 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. 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 switchedoff state and more than one minute after deactivating!Check whether the wall socket provides the appropriate mains power, which is the case if it is supplied with 230 V AC 50 Hz. Push the plug on the power cable supplied firmly into the power socket on the back of the appliance. Also select this type of main amplifier connection if you want to connect one speaker pair for bi-wiring. If you want, you can use the RCA sockets "REC OUTPUT" (12) on the back of the appliance to connect an analogue stereo recording device (e. ) or another appliance that is intended for receiving the unchanged, fixed stereo output level (line level) from the signal source selected on the amplifier at any given time. The output level is independent from the volume and tone settings (BASS, TREBLE, TONE, LOUD). Connection of two pairs of speakers: Four main amplifier channels are required in this case, e. Connect both sockets named "1" in the field "OUTPUT" with the RCA input sockets of the main amplifier channels for the first pair of speakers. Additionally connect the two sockets of the RCA combination marked with "2" within the SA-31MK "OUTPUT" terminal area with the RCA input jacks of the main amplifier channels for the second pair of speakers. [. . . ] One or more audio signal cables between pre- and main amplifier are defect or one of the plug connections is loose. You can try to use it at a different amplifier for a test. The cable connections are not tight, the connectors are dirty or a cable is defective. the tone settings on the dials "TREBLE" , "BASS" or "LOUD" have not been selected correctly. [. . . ]
