The Model 112's feature the two-tiered chassis design in which the power supply is separated from the amplifier circuitry. The Model 112's internal design effectively isolates sensitive signal circuitry from unwanted electromagnetic field contamination. A powerful toroidal power transformer gives the Model 112 the ability to handle even the most difficult loudspeaker loads with ease. The amplifier provides a full complement of balanced and single-ended inputs, a unique "wheel lock" binding post for secure loudspeaker cable connection and an on/off DC input jack for home theatre applications.

The recent development of digital sources capable of greatly enhanced playback resolution brings a wealth of design challenges to the world of high end audio. To meet these demands, innovative solutions to the inherent limitations of current amplifier design had to be developed to fulfil the promise of today's new digital formats. Introducing the Jeff Rowland Design Group Model 112, a digital-age amplifier more than equal to the demands of audio's new millennium.

Featuring a unique two-tiered chassis design in which the power supply is separated from the amplifier circuitry, the Model 112's internal design effectively isolates sensitive signal circuitry from unwanted electromagnetic field contamination. A powerful toroidal power transformer gives the Model 112 the ability to handle even the most difficult loudspeaker loads with ease.

The Model 112 utilizes a machined solid aluminium billet chassis that serves not only as an elegant testament to Jeff Rowland Design Group's well-earned reputation for superior artistic design, but offers a completely non-resonant and RF/EMI shielded platform from with the musical presentation can begin. The amplifier provides a full complement of balanced and single-ended inputs, a unique "wheel lock" binding post for secure loudspeaker cable connection and an on/off DC input jack for home theatre applications.

Internally, the Model 112 uses an ultra-fast, integrated circuit input/output topology that couples unquestioned reliability with unparalleled sonic performance. Modern "small geometry" surface mount technology provides the shortest possible signal path to attain unrivalled transparency. A low-impedance "balanced buss" power distribution system delivers clean, accurate DC power directly to critical circuit components. The end result is an amplifier with astonishing dynamics that far exceed its power rating.

Time to open the door to a new musical reality. The Jeff Rowland Design Group Model 112 - a beautiful realization of 21st Century audio.
