Introduction
Congratulations on your purchase of the Jeff Rowland Design Group Model 7 Mono
amplifier.
Please take a few moments to read this owners manual. Contrary to popular belief, there
is actually quite a bit of useful information in an owners manual. The Model 7 offers
tremendous interconnection flexibility regardless of the preamp used. A thorough
understanding of your amplifier now can save you a lot of anxiety later.
Features
• Lack of overall or nested negative feedback eliminates time domain distortion.
• Proprietary distortion canceling techniques minimize amplitude related distortions.
• Each transistor individually tested and matched for optimum operating
characteristics.
• Constant output impedance is maintained over the entire audio range, allowing for
universal compatibility with associated equipment.
• The large number of high-speed bipolar output transistors provides uncompromising
reliability and eliminates the need for electronic protection circuitry.
• A single voltage amplification stage utilizes field effect transistors (operating in
transconductance mode), which increases low-level signal recognition.
• The absence of capacitors, inductors, fuses and protection circuitry throughout the
signal path eliminates the adverse effects of these devices.
• A specially designed toroidal power transformer is supported by the substantial
output stage capability.
• All critical circuitry is encapsulated in a thermally-conductive epoxy to ensure
excellent thermal stability, mechanical integrity and to facilitate ease of service.
Unpacking Instructions
