Know before you buy
With 700 watts into 4 ohms, the Mono X is designed to drive almost any speaker, including demanding, low-impedance models that require significant current. Its high power output ensures that even difficult-to-drive speakers remain controlled and dynamic.
No, the Mono X uses a fanless, passive cooling design. The robust aluminum chassis acts as a heat sink, allowing for silent operation that won't interfere with your listening environment.
The amplifier features automatic input switching, but it is intended to be used with one source at a time. It will prioritize the signal it detects, so you should only have one active source connected to avoid potential interference.
No, the Mono X is not bridgeable. Because it is already a high-performance monoblock design with a dedicated 1200-watt power supply, it is intended to be used as a single-channel unit per speaker.
No, the Mono X is a dedicated power amplifier. It does not include a DAC, volume control, or any pre-amplification features, so you will need a separate pre-amplifier or a source component with volume control to manage your system.
The rear panel ground connection is included to help eliminate ground loops, which can cause hum or buzz in a system. It is particularly useful if you are integrating a subwoofer or have complex grounding needs in your audio setup.
