BRAMA Monoblock Power Amplifier

Nothing lost in translation.

 

With 600W RMS of output power into 4-ohms (1200W RMS into 2-ohms), the Brama Monoblock Power Amplifier’s high-current, Class AB lateral MOSFET output stage drives even the most demanding loudspeakers with total conviction.  

What sets our approach apart is how we achieve this power using only 3 matched output devices per rail, effortlessly revealing the subtlest nuances in your music. The amplifier’s two PCB stack and advanced layout and grounding techniques keep the signal and power paths short, ensuring optimal performance.

Additionally, heatsink temperature and speaker output current is continuously monitored and protected, ensuring long-term reliability and listening enjoyment.

 

An analog masterpiece.

 

The front panel of the Brama Monoblock Power Amplifier reveals a clean layout, luxurious feel, and timeless design that intentionally excludes digital displays and numerous buttons. 

A bespoke, analog output power gauge features a precision air core movement, responsive driver circuitry, and machined aluminum hand. Sapphire glass and a highly-polished stainless bezel seamlessly integrates the gauge to the front panel.  

Like a well-tuned engine.

 

The Brama Monoblock Power Amplifier features a custom switch-mode power supply designed to outperform conventional linear supplies. With 2400W peak output power and patented Belleson super-regulated outputs, it delivers high current with exceptionally low output noise and impedance. Its high-speed operation and low magnetic losses ensure ultra-fast transient response and superior pace, rhythm, and timing in music reproduction.

With active power factor correction (PFC) and superior regulation and stability, the power supply ensures maximum performance regardless of AC mains quality. Housed in a fully enclosed compartment precision machined into Brama’s solid aluminum body, it is fully grounded and isolated from the audio circuitry, performing like a highly-responsive, well-tuned engine.

The fusion of form and function.

 

Uncommon even among cost-no-object components, the main body of the Brama Monoblock Power Amplifier is precision-machined from a solid block of aluminum. This construction offers exceptional resonance control, complete shielding against electromagnetic interference (EMI), and ensures superior heat dissipation, thereby guaranteeing the long-term reliability of its internal components.

From an industrial design perspective, the seamless construction enhances the amplifier’s aesthetic appeal for audiophiles who value sophistication and elegance.
