I purchased these a year ago from a seller here with high ratings on USAudioMart. My project never materialized, so I'm letting them back out into the world. Never even opened the box.
Buyer pays PP and shipping from 97702.
*** Original description ***
One year old pair of Rythmik HX-300 servo amplifiers, from kid, cig, pet free home. Each used to drive a pair of GR Research 12" 16ohm free-air subwoofers in stereo configuration.
Has adjustable phase, crossover and slope, auto or manual power-on.
Always worked perfectly.
Please note it is a Servo amp and can only be used to drive subs designed for servo control like those from Rythmik and GR.
Will be packed in the factory twin-pack boxes.
Features include:
Harmonic distortion is less 0.01% at 200WRMS @4ohms (-1.5 dB from full output).
Toroid transformer based design for ultra high power supply reliability.
All OP amps on the signal paths are OPA2134 and TL072 for better sound quality (SQ) and richer bass sound.
Hypex Ucd module(s) are used in the power amplifier section for a smooth and articulate sound.
Three extension filter settings: Low-music (for music playback), Low-HT (for HT application) and High (for long play back time).
Signal to noise ratio: better than 107 dB (A-weighted).
Input impedance: 30k ohms.
Air tight by design. No need for a back cover or separate chamber. It will give you an extra 0.1 cu ft enclosure net volume compared with those with back covers.
Continuous phase adjustment (0-180) and low pass filter adjustment (50-200 Hz).
Gold plated connectors.
Brushed aluminum face plate.
Build-in thermal and short circuit protection circuitry.
The phase control is vastly improved so that it has better control in the non-HT setup.
Subwoofer crossover adjustable range is increased to 50-200 Hz for more flexibility.
This amp also carries a 2yr warranty against defects (does not cover abuse or installation errors). All other features such as protection circuits are same as regular amps.
