Jeff Rowland Design Group 1 owner manual Introduction, Features, Unpacking Instructions

Introduction

Congratulations on your purchase of the Jeff Rowland Design Group Model 1 stereo 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 1 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.
