4a. OptiOperation® Different System Configurations
In keeping with AMR’s philosophy that ‘no one sound fits all’ the AM-77 is also adaptable to suit virtually any
system configuration: able to operate at one end, as a pre-main stereo amplifier and at the other, as a single-
channel power amplifier. In pre-main amplifier mode, the AM-77 will use both the pre- and power amplification
sections: the AM-77 controls volume level and input selection controls. In power amplification mode, the AM-77
wil require an external, separate pre-amplifier to handle volume and input selection duties.
The following section describes alternative configurations for the AM-77 beyond the factory default: pre-main
stereo amplifier setting. With diverse system permutations in mind, the AM-77 has built-in, six OptiOperation®
modes to seamlessly integrate it into virtually any audio system configuration:
Mode I. Pre-Main Stereo amplifier mode (default)
Mode II. Pre-Main Monoblock amplifier mode
Mode III. Pre-Main Bi-amplifier mode (horizontal biamping)
Mode IV. Power amplifier Stereo mode
Mode V. Power amplifier Monoblock mode
Mode VI. Power Bi-amplifier mode (horizontal biamping)
The combination of synchronising multiple AM-77s together in practical terms is limited only by room size and
cost. This approach allows for systems at the core, comprising of any number of AM-77s to be constructed to
any level of complexity.
