UPA-500 Five Channel

About the UPA-500 Five Channel

The Emotiva UPA-500 is a five-channel power amplifier designed with a fully discrete, dual differential, high current, short signal path Class A/B topology. It delivers 80 watts RMS per channel into 8 ohms with all channels driven, and 120 watts RMS per channel into 4 ohms. The amplifier features a large 350VA toroidal power transformer and a 40,000uF power supply capacitance bank, providing ample headroom and dynamic power delivery. It has a frequency response of 10 Hz to 70 kHz (+0/-3 dB), a damping factor greater than 500, and a signal-to-noise ratio of 117 dB at rated power. The input sensitivity is 850 mV with an input impedance of 47 kOhms. Protection circuits guard against excessive temperature, shorted speaker connections, and ground faults. The unit includes gold-plated five-way binding posts for speaker connections, a 15mm solid milled aluminum faceplate, channel status LEDs, and automatic voltage detection for 115 or 230 VAC operation. Dimensions are 17" W x 4 1/16" H x 16 5/16" D, weighing approximately 23 lbs unboxed. It is praised for its solid build quality, clean sound with detailed highs and lows, and excellent value for the price, making it suitable for audiophile multi-channel setups and home theater systems.
