SolidDrive SD250 50W per Channel Class D Amplifier

For integrators specifying reliable audio in security, surveillance and commercial AV systems, the SolidDrive SD250 Pro Amplifier delivers efficient, intelligible power where it matters. This SolidDrive Class D pro amplifier provides 50W per channel into 8 ohms with a wide 20 Hz–20 kHz frequency response and up to 34 dB gain, ensuring clear paging, background music and monitored audio playback across control rooms and public areas. Multiple input options — balanced euroblock, unbalanced mini-jack and a speaker-level euroblock — speed installation by adapting to line-level consoles, DSPs or low-watt speaker outputs without extra converters. Built-in SolidDrive EQ presets for drywall, wood and glass optimize voice clarity in real-world mounting scenarios, while stereo/dual-mono/bridged-mono modes let you scale power for single-zone or multi-zone deployments. Power management features include signal-detect auto-standby and an external 12–32V trigger for centralized control, reducing energy use and simplifying system automation. Housed in a rugged aluminum case and backed by a 7-year warranty, the SD250 is engineered for long-term performance in security and monitoring installations.
