Know before you buy
A monoblock amplifier is dedicated to a single audio channel, which eliminates crosstalk between channels and provides a completely independent power supply for that specific speaker. This configuration ensures maximum power delivery and superior channel separation for a more precise, expansive soundstage.
The Cubed Series utilizes patented Quad-Complementary output circuitry that effectively mimics the sonic warmth and linearity of Class-A designs while maintaining the efficiency and low distortion of modern solid-state engineering. This results in a highly transparent, musical performance with significantly reduced noise and increased bandwidth.
Yes, the 7B³ is highly versatile and features both balanced (XLR and TRS) and single-ended RCA inputs. You can easily toggle between these input types using the selector switch located on the rear panel.
The amplifier is housed in a robust, fully aluminum chassis designed for convection cooling, meaning it does not use internal fans. While it is fanless and silent, you should still ensure it is placed in an area with adequate airflow to allow heat to dissipate naturally from the chassis.
Bryston’s 20-year warranty reflects the company's confidence in the long-term reliability and build quality of their amplifiers. Because each unit undergoes 100 hours of rigorous factory testing before shipping, the warranty serves as a long-term guarantee of the unit's durability and consistent performance.
The 7B³ features switchable gain settings of 23dB or 29dB, which can be adjusted via a switch on the rear panel. This allows you to better match the amplifier's sensitivity to your specific preamplifier and overall system configuration.
