Octave V 70 Class A: High-Fidelity Integrated Amplifier with Dynamic Bias Control

The Octave V 70 Class A is a premium integrated amplifier that combines the sonic purity of Class A operation with the dynamic performance of push-pull technology. This amplifier uses Octave’s innovative Dynamic Bias Control to deliver exceptional audio quality and versatility for discerning listeners.

Key Features

• Dynamic Bias Control: This proprietary technology dynamically adjusts the operating point, allowing the amplifier to deliver approximately 50 W RMS of Class A power, with peak outputs up to 70 W when paired with the optional Super Black Box. This ensures the tonal purity of Class A operation across the entire frequency range, even at maximum modulation.
• Flexible Tube Compatibility: The V 70 Class A supports various power tubes, including KT88, KT120, and KT150. A power selector switch allows users to optimize performance based on the chosen tubes, with ‘Power High’ for KT120 or KT150 tubes and ‘Power Low’ for KT88 or 6550 types.
• Auto-Bias Circuit: An automatic bias adjustment system ensures optimal tube performance without manual intervention. In contrast, an LED-based bias measurement system allows users to monitor the output tubes’ status.
• Advanced Protection Systems: This system incorporates soft-start electronics, comprehensive protection circuits, and an Eco Mode to enhance reliability and extend component lifespan.
• Versatile Connectivity: Equipped with five line-level RCA inputs (including a bypass input and an optional phono input), one XLR input, a regulated preamp output, and a home theater bypass function, accommodating various audio sources and configurations.
• Design and Build: The V 70 Class A is available in elegant silver or black finishes, housed in a robust aluminum chassis that combines durability with a sleek aesthetic. It includes a balanced input as standard, and an optional phono board (either MC or MM) is available for turntable connections.

The Octave V 70 Class A is a versatile and powerful integrated amplifier. It allows audiophiles to fine-tune their audio systems for an exceptional listening experience.
