amzn.to Amplifiers today need to be multi-faceted to keep up with the task at hand. Versatility is the foundation upon which the Dayton Audio APA150 is based. Configured in stereo mode, amplification is provided to a pair of speakers for stereo or surround playback. Select bridge-mono mode and the APA150 is configured for powering a center channel speaker, or a subwoofer/tactile transducer when used with the on-board low pass filter. Full-range line-level outputs allow for daisy chaining amplifiers for a multi-room whole house audio system or for bi-amp applications. A smaller chassis consumes less space than conventional amplifiers making placement options virtually endless. Key features of the APA150 are high current, discrete power transistors (used in premium amp designs), a hefty toroidal power supply transformer, low-noise forced air cooling, a fully adjustable&##151;and defeatable&##151;electronic 50-150 Hz low-pass filter (18 dB/octave), and complete protection against electrical shorting and thermal overload. Also included is auto-on/off, silent turn-off with no audible transient, gold plated RCA inputs/outputs, and 5-way binding posts. Features and Specifications: *Measured power output: 2 x 75 watts RMS (into 4 ohms @ less than 0.01% THD) *Signal-to-noise ratio: greater than 100 dB *Class A/B design topology *Input impedance: 47k ohms *Auto-on sensitivity: 3 mV *Voltage requirement: 120/230 VAC, 60/50 Hz *Dimensions: 5-1/2 H x 6 W x 11-1/2 D. www.amazon.com
