Brand

Emotiva

The Emotiva UPA-7 was a popular 7-channel power amplifier known for its robust build and significant power output, especially for its price point when it was available. It's a "classic" Emotiva product that many enthusiasts still seek out. Here are the key features of the Emotiva UPA-7: Power & Performance: * 7 Channels: Designed to power a full 7.1 channel home theater system. * High Power Output (Class A/B): * 125 Watts RMS per channel into 8 Ohms (all channels driven at 0.1% THD) * 185 Watts RMS per channel into 4 Ohms (all channels driven at 0.1% THD) * Note: Emotiva was known for providing honest, all-channels-driven power ratings, which is a significant advantage over many AVRs that only quote 2-channel driven power. This means it has ample power for demanding home theater scenarios. * Massive Toroidal Power Transformer: A key indicator of a serious power amplifier, providing a stable and abundant power supply. * Large Capacitance Bank: Features 90,000uF total power supply capacitance, helping to deliver dynamic bursts of power when needed for impactful sound. * Fully Discrete, Dual Differential, High Current, Short Signal Path Class A/B Design: This audiophile-grade amplifier topology is designed for clean, accurate, and powerful sound reproduction with minimal distortion. * Wide Frequency Response: 20 Hz to 20 kHz with less than 0.05dB deviation at rated power, and a broadband frequency response of 5Hz to 150kHz (-3dB). This indicates excellent linearity and extension. * High Signal-to-Noise Ratio: >120dB (full power), meaning a very low noise floor for clear audio. Connectivity & Build: * RCA Inputs: Seven unbalanced (RCA) inputs for connecting to a preamplifier or AV processor. * 5-Way Binding Posts: Seven pairs of robust, high-quality binding posts for secure speaker cable connections. * 12V Trigger In/Out: Allows for integrated power control with other compatible home theater components (e.g., turning on/off with your pre-amp/processor). * Solid Chassis: Known for being a substantial and well-built amplifier, contributing to its durability and performance. It weighs around 66 lbs. * Automatic Voltage Detection: A relatively rare and convenient feature that allows it to automatically detect and switch between 120V and 220V line voltage. Key Design Philosophy: The UPA-7 embodies Emotiva's philosophy of delivering high-performance, audiophile-grade components at accessible prices. It focuses on raw power, clean amplification, and robust construction without extraneous features like digital-to-analog converters (DACs) or network streaming, which are typically handled by a separate pre-processor or AV receiver. If you have a UPA-7, you have a very capable power amplifier that can drive a wide range of speakers with authority, providing a dynamic and clear audio experience for your home theater.
