The Reference 7250/7260 series II purpose and function
The Reference 7250/7260 series II is a high current, five/six channel power amplifier. It
is designed to be used in all types of audio or audio/video systems.
Design and construction
The Reference 7250/7260 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 7250/7260 series II operates class A predriver and AB high current
MOSFET power output stages. It is capable of reproducing the most demanding audio
signals at rated power levels.
Features
Toroidal Transformers - Efficient, high current, shielded transformer.
Discrete Circuitry - More accurate and three dimensional reproduction of
source material.
Class A Predriver - Improves low level detail for smoother, more musical
sound.
AB MOSFET Output Stage - For efficient linear power delivery and protection from
thermal overload
Gold Plated Connectors - Improved connections for better sound and minimized
signal loss and degradation.
1% Metal Film Resistors - Low noise resistors for better sound and a greater
degree of repeatability.
High Current - Ability to reproduce demanding recordings.
Computer Grade Capacitors - Large capacity computer grade electrolytic capacitors for
extended low frequency control and improved dynamics.
Fused Outputs - Provides protection from accidental shorting of amplifier
outputs.
Heavy Duty Binding Posts - Improved current carrying capacity and ease of use.
