While many contemporary amplifiers waste 50% or more of the power they pull from the wall as heat, the SA-series amplifiers run at approximately 90% efficiency. As a result, more power is available for the loudspeaker, and less is wasted as heat in your room. The high efficiency of the SA-series design also means that the amplifiers can be placed in close proximity to each other, as in an equipment rack, without undue overheating. Product selection, amplification, processing, placement and acoustic integration should be confirmed as part of the complete system design.<\/p>\n<h2>Key benefits<\/h2>\n<ul>\n<li>Engineered for premium private cinema and high-performance music systems<\/li>\n<li>Professional system matching for coverage, output and room volume<\/li>\n<li>Designed for integration with Wisdom Audio loudspeakers, subwoofers and electronics<\/li>\n<li>Installation and calibration planning available from Mirror Edge Networks<\/li>\n<\/ul>\n<h2>Technical specifications<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Rated Power Output Per Channel<\/th>\n<td>500 w\/ch continuous RMS power @ 4 ohms above power ratings from 20 Hz\u201320 kHz at &lt;0.5% THD<\/td>\n<\/tr>\n<tr>\n<th>Peak Output Current<\/th>\n<td>&gt; 30 amps<\/td>\n<\/tr>\n<tr>\n<th>Voltage Gain<\/th>\n<td>31 dB<\/td>\n<\/tr>\n<tr>\n<th>Signal to Noise Ratio (Main Outputs)<\/th>\n<td>\u2013103 dB (ref 1V rms, A-wtd.)<\/td>\n<\/tr>\n<tr>\n<th>Input Impedance<\/th>\n<td>25k ohms (balanced)<\/td>\n<\/tr>\n<tr>\n<th>Output Impedance<\/th>\n<td>Less than 0.05 ohms from 20\u201320,000 Hz<\/td>\n<\/tr>\n<tr>\n<th>Input Sensitivity<\/th>\n<td>1.2V for full output<\/td>\n<\/tr>\n<tr>\n<th>Polarity<\/th>\n<td>Non-inverting, Pin 2 positive<\/td>\n<\/tr>\n<tr>\n<th>Thermal Load<\/th>\n<td>7 BTU\/minute or less<\/td>\n<\/tr>\n<tr>\n<th>Power Consumption<\/th>\n<td>See &quot;Wisdom Electronics \u2013 Current Draw &amp; BTU Info&quot; in the Resources Section below<\/td>\n<\/tr>\n<tr>\n<th>Main Voltage Ranges<\/th>\n<td>100V, 120V, or 230\/240V determined by the needs of country for which the unit was manufactured; cannot be reset by dealer or user<\/td>\n<\/tr>\n<tr>\n<th>Shipping Weight<\/th>\n<td>40 lbs.
