Elegance. That’s what the UPA-1 Ultra Mono-block Amplifier offers. Employing a mono-block system in an audio setup gives you a dedicated power supply for each channel. The reward is refined sound and a jet black noise floor. Crosstalk is eliminated by complete inter-channel isolation. Dynamic behavior is consistently superior under complex loads and power demands. Your soundstage achieves a new level of depth and lucidity.
Build a two channel, five channel or seven channel system with UPA-1s, or combine them with other Emotiva amplifiers to suit your needs. For an ideal and economical 5 or 7 channel setup, combine 3 upa-1s with one or two UPA-2s (to power your surrounds).
If you've wanted to explore the possibilities of a mono-block setup, but felt restricted by the size and cost of suitable amplifiers, the UPA-1 could be the solution you've been seeking. The elegant solution.
Performance
The UPA-1 features a 300VA torroidal and one of our 'X' series power modules, supplying 200 continuous watts into 8ohms, and 350 watts into 4ohms. Extremely low output impedance, 80,000 uf of power supply capaticance, and uncompressed dynamic reserve make this amplifier truly exceptional.
Quality
Made with the same high quality components as all Emotiva amplifiers, and featuring both balanced (XLR) and unbalanced inputs, as well as in and out trigger connections. Dual output terminals make bi-wiring an easy option.
Space Management
The compact 2RU chassis (same as the UPA-2) make the UPA-1 easily stackable, maximizing the use of space in your home theater or two channel setup.
