Dayton Audio - SA1000 Subwoofer Amplifier Rack Mountable

The Dayton Audio SPA1000 subwoofer amplifier provides nearly a kilowatt of clean, reliable audio power—just what you need to get big sound out of large, low-efficiency subwoofer speaker systems.

The XMP100 GEN2 is a versatile Class D stereo amplifier for home, studio and desktop sound systems. It delivers 50W x2 RMS into 8 ohms, 100W x2 RMS into 4 ohms, or 200W bridged mono into 8 ohms, with a signal-to-noise ratio above 90dB for low-noise, clear reproduction. Four separate inputs include 24/192 USB audio and dual line-level inputs with automatic source switching: connect a TV or digital audio device as the main source and a music streamer to the interrupt input, and the amplifier switches automatically when the secondary source starts playing, then returns to the primary when it stops. Front-panel volume, balance and A/B speaker selection plus bass and treble controls let you tune the sound to the room. Two speaker pairs can be connected and switched on or off at 8 ohms, which is useful for adding outdoor or second-room speakers. Trigger and auto-sensing power modes let the amplifier be hidden away once configured. Multi-voltage 100V to 240V operation, 2-year warranty.

The Dayton Audio SPA300-D high-efficiency subwoofer plate amp packs big-amp features into a compact chassis that is ideal for installation into cabinets that can't accommodate bulky old-style amps.
