Cambridge Audio 540A/640A Integrated amplifier, Bi-amping, Using Speaker B connections

540A/640A Integrated amplifier

Bi-amping

The azur amplifiers are equipped with PRE-OUT sockets. If your loudspeakers have two sets of terminals then it is possible to bi-amp your system using a further power amplifier. Bi-amping uses two amplifiers to drive the bass and treble units in the loudspeakers independently, resulting in even greater clarity coupled with improved control and dynamics. An example of a bi-amp setup is illustrated in the diagram adjacent.

Please note that if using a second azur amplifier as the slave amplifier, any line input can be used to connect from the master’s Pre-Out.

Using Speaker B connections

The Speaker B connections on the back of the amplifier allow a second set of speakers to be used, which could be for another room.
