Know before you buy
Yes. With 500 watts per channel, this amplifier is specifically designed to maintain control over low-sensitivity or complex speaker loads that would typically struggle with lower-powered equipment.
No, the M6 500i does not include an internal phono stage. You will need to use an external phono preamplifier connected to one of the line-level RCA inputs if you plan to use a turntable.
One of the RCA inputs is switchable to a home theater pass-through mode. This allows you to integrate the M6 500i into a surround sound system by letting an external AV processor control the volume for the front channels.
Yes, the M6 500i features a balanced XLR input, which helps reduce noise and interference, particularly when using longer cable runs from your source components.
The variable level output allows you to connect an external power amplifier or an active subwoofer. Because the level is variable, the volume control on the M6 500i will adjust the output to these connected devices simultaneously.
Like most high-powered class AB amplifiers, the M6 500i will generate heat during use. It is important to place the unit in a well-ventilated area with sufficient clearance on the top and sides to ensure proper airflow.
