In the following section we take you step by step to ensure correct wiring of the components in your MBL Cadenza Line Stereo System. The Cadenza Line also offers you other wiring set-ups in addition to the recommended installations given here. Your hi-fi dealer will be glad to advise you. ATTENTION: Unplug the power cord before starting wiring! COMBINATION CD-DAC C31 AND THE INTEGRATED AMPLIFIER C51 As you wish, your CD-DAC may be connected to the integrated amplifier either using cable with Cinch/RCA plugs (asymmetrical or single-ended connection) or with XLR plugs (symmetrical or balanced connection). For this connection we recommend that you use a single-ended connection through high quality cable terminated with Cinch/RCA plugs. -
Page 17: Wiring The Loudspeakers
Please ensure that the red part of the cable is connected to the positive terminal (red) on both the amplifier and the speaker. Please also make sure that the correct loudspeaker (left or right) is connected to the proper terminal (L or R) on the amplifier. Repeat this procedure with the second loudspeaker cable for the other side connection. right speaker left speaker Integrated Amplifier C51 COMBINATION CD-DAC C31, PREAMPLIFIER C11 AND STEREO POWER AMPLIFIER C21 Your CD-DAC as well as the preamplifier and the stereo power amplifier can be connected either using single-ended cables with Cinch/RCA plugs (asymmetrical or single-ended connection), or with cable using XLR plugs (symmetrical or balanced connection). Any connection methods may be combined. For both connections we recommend that you use a high quality single-ended cable with Cinch/RCA plugs. NOTE: The connection between the preamplifier and the stereo power amplifier should consist of either cables with Cinch/RCA plugs or of cables with XLR plugs but NOT of both types together simultaneously. -

3.2.3 WIRING THE SPEAKERS Take one of the loudspeaker cables and connect one end to the loudspeaker terminal on the amplifier and the other end with the loudspeaker. If the cable is directional, please follow the direction of the cable so the signal flows away from the amplifier towards the loudspeaker. Please ensure that the red part of the cable is connected to the positive terminal (red) on both the amplifier and the speaker. Please also make sure that the correct loudspeaker (left or right) is connected to the proper terminal (L or R) on the amplifier. Repeat this procedure with the second loudspeaker cable for the other side connection. -

SmartLink, which allows you to operate the components more easily. This connection allows for example to switch the components on and off at the same time, as well as to adjust the display brightness in parallel. If the CD-DAC C31 is part of an MBL Smart Link chain, the input selection is taken over and controlled by the preamplifier C11 / integrated amplifier C51. To establish the connection, use the SmartLink connection cable included in the delivery and plug it into the socket labeled SmartLink. -
