W ith its combination of features such as variable multi-channel configuration, numerous function controls, interconnect possibilities, precision electronic circuitry, and accurately machined chassis components throughout, your MC-6 Multi-Channel Power Amplifier will offer you many years of musically satisfying enjoyment. P lease take a few minutes to read the remainder of this Owner's Manual before proceeding with the installation of the amplifier. 2911 North Prospect Street Colorado Springs, CO 80907 T elephone: 719-473-1181 F ax: 719-633-4158 E -mail: jrdg@jeffrowland. com W eb: www. jeffrowland. com thorough understanding of the operational features will allow you to gain the maximum performance and ease of use for which this amplifier was designed. [. . . ] This flexibility means monoblock, two-channel stereo, bi-amplification, tri-amplification, and a number of home theater applications can be realized within a single amplifier chassis with a few easy adjustments. Within the amplifier there are two high-current amplifier sections and four standard amplifier sections. These amplifier sections can be linked to each other to configure the amplifier for different applications. The configuration procedure for the MC-6 Multi-Channel Amplifier is a quick and simple procedure, able to be performed within minutes with no additional tools or disassembly required. F or certain configurations, the outputs of multiple channels must be linked using short sections of Output Terminal Linking Cable. Linking Cables manufactured specifically for the MC-6 are available from Jeff Rowland Design group or can be made from the same basic materials as your selected loudspeaker cables. Please have your loudspeaker cable manufacturer contact the Jeff Rowland Design Group factory for proper instruction in the construction of these linking cables. T echnical Note: Linking (paralleling) multiple channels together is not similar to "bridging" and is an exclusive feature due to the unique circuitry of the MC-6. Linking channels together increases the maximum current available and decreases the electrical load of each linked channel. This yields improved electrical and sonic performance, especially under demanding conditions. For example, if channels 1 through 6 are linked together, the result is a single channel with a maximum output current capability equal to the sum of the current capability of channels 1 through 6. When linking channels, performance of the amplifier actually increases as a greater number of channels are linked together.
