[. . . ] For the best results we recommend that you use Musical Fidelity X-LINX "no-nonsense" interconnect cables for this connection. Connect your loudspeaker to the loudspeaker terminals situated on the back panel marked "Loudspeaker Output" Once these connections are made, plug in the IEC type mains lead and switch on the unit. Bi-Amping The X-A50 has a "Loop Out" facility to allow for easy biamping of speakers with bi-wireable crossovers. In this kind of setup typically one X-A50 is used to drive the tweeter (high frequencies) and one to drive the woofer (low frequencies) of each loudspeaker enclosure. Taking the left channel connections first, the pre-amp's (or other source's) left output is first connected to the first X-A50's line input and then that X-A50's loop output is connected to the second X-A50's line input, both X-A50s will now be driven from the same left channel signal. The first X-A50 can now be used to drive the woofer and the second, the tweeter of the left channel loudspeaker. If you are in any doubt about bi-amping, please contact your dealer who will be able to help and advise you. Installation Precautions Your new X-A50 is designed and built to provide trouble-free performance, as with all electronic devices it is however necessary to observe a few precautions. Please ensure that you have complied with these before you connect the power to your X-A50. [. . . ] Please refer all service work to an authorised Musical Fidelity agent. [. . . ]
