The Emotiva UPA-500 is a five-channel Class A/B power amplifier rated at 80 watts RMS per channel into 8 ohms and 120 watts RMS per channel into 4 ohms, with all channels driven. It uses a fully discrete, dual differential, high current, short signal path Class A/B topology and a single 350VA toroidal power transformer with 40,000 µF of total power supply capacitance for strong dynamic headroom and stable multi-channel performance. Frequency response is specified at 10 Hz to 70 kHz (+0 / -3 dB), with rated power bandwidth of 10 Hz to 20 kHz (+/- 0.06 dB) and broadband response extending beyond the audio band. The amplifier offers a damping factor greater than 500, signal‑to‑noise ratio up to 117 dB at rated power (A‑weighted), input sensitivity of 0.85 V for full output into 8 ohms, gain of 29 dB, and input impedance of 47 kOhms, making it easy to drive from typical home theater processors and preamps. Connectivity and construction include unbalanced RCA inputs (one per channel), gold‑plated full-size five‑way binding posts for each of the five channels, remote trigger input and output (3.5 mm; compatible with 5–20 V triggers), and automatic AC voltage detection and switching for 115 or 230 VAC, 50/60 Hz operation. The chassis features classic Emotiva styling with a rugged steel enclosure, 15 mm solid milled aluminum faceplate, and front‑panel channel status LEDs. Physical dimensions are approximately 17" W x 4 1/16" H x 16 5/16" D, with an unboxed weight around 23 lbs (Emotiva and retailers list ~22.9 lbs). Protection circuitry covers over‑temperature, shorted speaker outputs, ground faults, and other common fault conditions to help ensure long‑term reliability in home theater and multi‑channel music systems. Widely regarded as offering clean, detailed sound and a very strong performance‑to‑price ratio, the UPA‑500 is well suited to audiophile‑grade multi‑channel setups and modest‑to‑medium‑power home theater installations.
