Rythmik Audio A250 Basic
This high performance amplifier is the perfect match for most home theater subwoofer systems. Packing 250 watts into 4 ohms at 0.1% THD of class A/B power, this amplifier provides enough power to shake the walls when mated with the subwoofer drivers listed on the drivers page. It features the standard rumble filter with a Q=.7 at 12Hz and is also adjustable by replacing 2 resistors on the preamp board. While this amplifier may look similar to others on the market it has been modified slightly. Several of the modifications are: 1. A modified ground loop that reduces the hum noise. 2. A modified preamplifier board that completely eliminates the distortion caused by the auto-detection circuit. This results in a lower distortion. 3. The xover for subwoofer has been extended to 250hz (see manual for details) 4. The highpass filters for satellite speakers are modified to 80hz with Q=0.6 (-3db @100hz). This is an excellent value on an excellent product. 1 year warranty.
