THE REFERENCE 7270 SERIES II PURPOSE AND FUNCTION
The Reference 7270 series II is a high current, seven channel power amplifier. It is
designed to be used in all types of audio or audio/video systems.
DESIGN AND CONSTRUCTION
The Reference 7270 series II utilizes high quality electronic circuitry to achieve an
environment wherein a detailed, transparent, and highly musical sound can be realized.
The high quality parts complement includes; state-of-the-art solid state devices, 1% metal
film resistors, computer grade electrolytic power supply capacitors, and a high capacity
toroidal transformer.
The Reference 7270 series II operates with a class A predriver and AB high current
MOSFET power output stages. It is capable of reproducing the most demanding audio
signals at its rated power levels.
FEATURES
THX Ultra Certified - The unit has passed a rigorous series of Lucasfilm THX quality and
performance tests and it is guaranteed that this amplifier will give superb performance for
years to come.
Toroidal Transformer - Efficient, high current, shielded transformer that supplies the
amplifer with a clean and constant supply of power, even during highly demanding
source material passages.
Discrete Circuitry - Dynamically provides a full, accurate, and three dimensional
reproduction of source material.
Class A Predriver - Improves low level detail and clarity for smoother, more musical
sound.
AB MOSFET Output Stage - Provides efficient and linear power delivery, as well as
protection from thermal overload.
Gold Plated Connectors - Improved connections for better sound quality and minimized
signal loss and degradation.
1% Metal Film Resistors - Higher quality resistors for lower noise, better sound, and a
greater degree of repeatability.
High Current - Ability to cleanly, accurately, and reliably reproduce demanding
recordings or source materials into low impedance drivers and speaker systems.
Computer Grade Capacitors - Large capacity computer grade electrolytic capacitors for
extended low frequency control, increased power supply, and improved dynamics.
Fused Outputs - Provides limited protection from accidental shorting of amplifier outputs.
Heavy Duty Gold Binding Posts - Improved current carrying capacity and sound quality
