Know before you buy
With 250 watts per channel into 8 ohms and 500 watts into 4 ohms, this amplifier is designed to drive demanding, low-impedance speakers with ease. It provides the necessary current to maintain control over large woofers while preserving the delicate detail required for high-end tweeters.
Yes, the amplifier utilizes a Class A/B topology and features large, prominent heat sinks to manage thermal output. It is normal for the unit to become quite warm, so ensure you provide adequate ventilation space around the chassis for proper airflow.
The dual-mono design treats each channel as an entirely independent amplifier, which effectively eliminates crosstalk and interference between the left and right signals. This results in a more expansive soundstage and improved channel separation.
The X250.8 is designed to accept either balanced (XLR) or single-ended (RCA) inputs, but you should only connect one source type at a time. Using both simultaneously can lead to signal interference or potential damage to your connected components.
The Class A/B design balances the refined, low-distortion characteristics of Class A operation with the efficiency and power of Class B. This allows the amplifier to deliver a transparent, nuanced sound while maintaining the raw power needed for dynamic musical peaks.
