Description :
The B&K Reference 7270 Series 2 amplifier is a seven channel, and very versatile power amplifier designed to be used in all types of audio or audio/video systems. It is a LucasFilm THX Ultra certified unit, passing series of stringent quality and performance tests to guarantee long term performance. The amplifier is built like a tank and feels bullet proof while having a high performance/high value ratio. The B&K Reference 7270 Series 2 utilizes high quality electronic circuitry to achieve detailed, transparent, and highly musical sound. It operates with a class A predriver and AB high current MOSFET power output stages, capable of reproducing the most demanding audio signals at its rated power levels.

The B&K Reference 7270 Series 2 uses efficient and highly efficient toroidal transformer to power the amplifier to perform at its best, even during complex passages. The circuitry dynamically provides a full, accurate, and three dimensional audio reproduction. The class A predriver improves low level detail and clarity for smoother, more musical sound. The AB MOSFET output stage helps to achieve efficient and linear power delivery, and thermal overload protection. Driven with high current and 1% metal film resistors, they provide higher quality resistors for lower noise and accurate recordings into low impedance drivers and speaker systems. The large capacity computer grade electrolytic capacitors extend low frequency control, increase power supply, and improve dynamics. It is supported by heavy duty gold binding posts that improve current carrying capacity and sound quality. The B&K Reference 7270 Series 2 is a perfect power amplifier that matches up with most hi-fi equipments to provide a clean and powerful sound that will satisfy listeners for decades to come.
