The BLADE Series Amplifiers are designed with our “Price that Plays” motto. Blade amplifiers make CTA 2006 certified power and all but the B2000.1 are Class A/B full range. The built-in OEM line converters found in very model of BLADE use DC off set to activate the ATO (Auto Turn On). The RCA inputs can take high level speaker signal at up to 9 Volts in. BLADE even has a convenient 12V out feature to power up other products and a preparatory docking input for the custom built 4 Farad Rail Capacitor (RAILCAP-B). All multi-channel crossover adjustments can be programmed as high or low pass @ up to 3 KHz or Band Passed enabling the use with raw drivers. This ensures that no competition can stand up to the BLADE when it comes to features, performance and value.

The Massive Audio “Rail CAP B” was designed for all Blade Series High Performance Amplifiers. With Massive Audio's "Direct Plug & Perform" technology this powerful 4 Farad Capacitor with back lit Massive logo simply plugs directly into a dedicated docking port found on the end cap of the Blade Series amplifier. The Rail CAP B is then automatically connected directly to the amplifiers internal power supply. When needed on demand (within milliseconds) the Rail CAP B will charge & discharge lighting fast power that will help stabilize the amplifiers power supply improve overall performance.
