Marantz MM8077 - 7 Channel Power Amplifier

Description

The Marantz MM8077 is a 7-channel power amplifier delivering 150W per channel at 8 ohms, built with a current feedback discrete design and a massive toroidal transformer for handling demanding low-impedance speaker loads. It offers balanced and unbalanced inputs on every channel, suitable for 5.1, 7.1, or larger 11-channel systems.

Features

• Current feedback discrete amplifier with Wilson current mirror circuit
• Large toroidal power transformer with 100,000µF total capacitance
• Chimney-shaped heat sinks with temperature-controlled cooling fans
• Balanced and unbalanced inputs on every channel
• IR flash input and DC trigger input/output for custom installations
• Remote power on/off sync with compatible Marantz pre-amplifiers
• Auto-standby after 30 minutes of no signal; standby power under 0.4W
• Gold-plated speaker terminals, copper-plated chassis
