Pride DX400 4-pill Linear Amp

The Pride SUPER DX-400 Mobile is a compact, high-drive amplifier built with four HG2879 transistors. Designed for mobile operators seeking reliable performance, this unit is optimized to run at 15.1 VDC when paired with a Pride DX 2-pill (250 or 350).  

Delivering up to 400 watts RMS at 15.1 VDC (and as much as 600 watts RMS at 18 VDC), the DX-400 offers a strong balance between continuous and peak output. With peak performance up to 1200 watts, this amplifier is built for serious operators but should be run responsibly for long-term reliability. Recommended safe operating range is no more than 150 watts RMS and 1000 watts peak.
