According to Rotel, the RB-1080 stands near the peak of the company’s line of two-channel amplifiers. Users hear audio content, whether its music on a CD or a movie on a Blu-ray DVD, the way it was meant to be heard with this high-current amplifier.This Rotel power amplifier is designed to put out 550 watts of maximum power for any auto stereo system. Whats more, Rotels own proprietary toroidal transformer delivers separate power to each of the channels. It splits that supply between the two channels with an output of 200 watts per channel. All channels are driven unbridged from 20 Hz to 20 kHz at 0.03 percent THD (total harmonic distortion) into 8 Ohms. Each channel also gets its own voltage regulators, capacitor banks, and rectifiers. With a frequency response ranging from 15 Hz to 100 kHz, the Rotel stereo amp produces a truer and crisper sound that listeners truly appreciate. A 1,000 damping factor gives it the incredible capability to capture even the most stubborn hi-fi signals. Then, it regulates diaphragm motion with absolute precision for excellent audio quality. Also providing instant response to these more challenging hi-fi signals are British BHC Slit Foil storage capacitors with lightning-fast charge and discharge times.As much attention was paid to form as to function in the design of these amps. For example, they feature front panel heat sinks that add a stylish visual accent that blends into your decor. At the same time, these heat sinks augment heat dissipation. That makes these amps particularly useful in closed or cramped spaces. Situated between these two stylish heat sinks is a simple polished front face with just a power switch and light along with second protection light. The amp is designed with its power light located on the front panel to let the user know when it is working properly. The protection indicator light then shows when the internal circuits have shut down.Color-coded speaker connection plug-ins on the back panel of the amp allow for easy wire connection to most speakers. The interface boasts switchable balanced and unbalanced inputs (XLR and RCA) to provide massive system configuration flexibility. That means it connects to a wide array of audio components, including home theater systems. This amplifier also boasts separate inputs and outputs for 12-volt trigger signals, as well as a conveniently detachable AC cord.

2xMA12070 Fully balanced Class D amplifier - Each channel of PA3s uses one MA12070 Class D power amplifier chip. This allows separation in layout improving performance and reducing crosstalk. The power is shared across two chips, the heat dissipation is also halved for each chip, improving reliability and extending the lifespan of the productHigh output power - PA3s could output 80W x2 at 4ohm load, 10% THD+N. In higher standard of THD+N of 1%, output power will be 65W x2 at 4ohm load. The output power is enough to drive any bookshelf speakers and even some floor speakersBalanced + Single -ended inputs - PA3s provides TRs balanced input and RCA single -end- ed input. The use of balanced input eliminates potential ground loop problems giving the pristinely clean audio without any hum.Two inputs are selectable using front panel button. P A3s will remember the input selected when it was turned off.Comfort zone with lowest distortion - The lowest THD+N of PA3s is in the range of 10-20W output, which happens to be the power range commonly used for listening to music. Everything is just in the rightconditionWider Use - With the help of a DAC, the function is expanded toa greater extent PA3s can be used with a DAC to expand the categories of digital inputs; if used with a DAC+HPA, more comprehen- sive functions can be achieved.

For sale is a pair of Emotiva Stealth PA-1 Class-D Monoblock Power Amplifiers. They offer high power and audiophile quality sound in a small and light package. Class D amplifiers mostly arent known for audiophile quality, but these really do it. I tested them recently and compared them to the traditional Class-A monoblocks that Im using now, and they compared very well. A little less depth and clarity than the big amps, but very close, at a whole lot cheaper price. And, compared to an older Conrad-Johnson high power class A/B audiophile amplifier, these are better. They have enough power to drive demanding speakers, even ones with impedance as low as 2.5 ohms. From the Emotiva PA-1 manual: Specifications Circuit Topology The Emotiva Stealth PA-1 Class-D Monoblock Power Amplifier is a fully balanced high-performance Class D power amplifier featuring the ICEpower ASC300 amplifier module. The ICEpower ASC300 is self-contained, and includes an audiophile-grade class D power amplifier, and an integral high-performance switch mode power supply. Connections Speaker connections: Audiophile grade, insulated, gold plated, 5-way binding posts (one pair). Audio input: Balanced input; accepts balanced XLR, balanced or unbalanced 1/4, with adapter for unbalanced RCA plugs.Power: Standard IEC AC power receptacle; accepts all standard IEC power cables. Controls and Indicators Status LED: Front panel LED; Illuminates blue when the PA-1 is powered on. AC Power Switch (rear panel rocker switch): Switches AC power to the PA-1 on and off. Auto/On Switch (rear panel slide switch): Configures the PA-1 to remain on continuously or to automatically switch on when an audio signal is detected at its input. Power Line requirement: Between 100 VAC and 264 VAC @ 50 / 60 Hz (automatically detected). Standby power: Approximately 0.275 watts. Total power efficiency: Approximately 80% Protection The Stealth PA-1 is protected against excessive temperature, short circuit conditions, excessive DC offset at the output, and various input signal fault conditions. The protection circuitry in the PA-1 is totally transparent in normal operation. If a fault is detected, the PA-1 will instantly mute its output, and continue to monitor the situation. As soon as the fault is removed, the PA-1 will automatically reset itself and return to normal operation.
