Marshalls long history and experience in the field of valve amplification was utilized in the development of the new AVT power amp. AVT has evolved from their original, critically acclaimed Marshall Valvestate technology, but is vastly improved so it emulates the tone, feel, and response of their world-renowned, all-valve amplifiers with unerring accuracywithout using valves in the power stage. In Marshalls quest to give players the ultimate tone at a realistic price, they have combined the latest innovations in valve, solid state, and digital technologies to achieve optimum sonic performance. You will feel all the extra depth and sheer tonal weight of which only a head with a 4x12 is capable! For even greater power and projection, the AVT50H will also drive the industry standard 1960 4x12 in. Switching to Overdrive takes you from those classic rock tones right through to the most contemporary slamming sounds. Powering the purpose-built AVT412A (angled) and/or AVT412B (straight) 4x12 in., 200-watt, Celestion loaded cabinets, the AVT50H will deliver crisp clean sounds and roaring crunch in abundance.
Also all Marshall AVT products, including the Marshall AVT50H, will deliver the goods in the often hostile and unpredictable environment of the live performance stage.The AVT50H is the head version of the AVT50 combo and is armed with the exact same features. Using frequency dependent power amp damping and Marshall's proprietary, dynamic clip level technology (which emulates the HT supply of a valve power amp), each AVT power stage creates the warm, musical feel and 3-dimensional sounds that have made Marshall's all-valve power amps world-renowned. Power Amp Delivery The same, unrivalled design expertise that went into the pre-amp was also channelled into the design of the AVT power stage. Whenever you select an AVT Overdrive channel, the ECC83 is saturated to its limit, providing dynamics and feel worthy of a place in the Marshall hall of fame. The resulting clean sounds ring with the bell-like harmonics that only a valve pre-amp can deliver and the break-up is never harsh or unnatural sounding. Marshall has gone to great lengths to ensure that this precious device delivers maximum sonic benefit at all settings and volume levels. Instead it is playing the central role in the gain, distortion and tone generating circuitry. Unlike other hybrid amps out there, this valve isn't merely acting as a pilot light. Valve Drive Pre-amp Every Marshall amp in the AVT line, including the Marshall AVT50H, boasts a pre-amp stage that is driven by an ECC83 Dual Triode valve. Tube Warmth & Solid-State Convenience Meets Digital Power In Marshall's quest to give players the ultimate tone at an unbelievable price, they have combined the latest innovations in valve, solid state and digital technologies to achieve optimum sonic performance in the AVT line of amps. Crank the Overdrive channel's Gain control to the max and you have a contemporary high gain sound that packs an unbelievable punch, staying tight and focused thanks to the carefully designed closed back cabinet. The AVT50H has two footswitchable channels for glistening clean tones and a roaring crunch that just oozes vintage authenticity.
