EMOTIVA UPA-500 Five Channel Power Amplifier

 The UPA-500 and it's a new five channel amplifier from Emotiva with a price tag under $400. While it may NOT be a perfect amplifier, it comes as close to perfection for a product beyond its price class. The UPA-500 delivers clean, low noise, meaty amplification that will surely bring new life to a whimpering department store A/V receiver. It’s honestly rated and has no issues driving low impedance loads while remaining cool in operation even under the most strenuous test conditions on the bench. If you’re looking for a step up in sound quality and power on the cheap, I can’t think of a better option on the market. Highly recommended

Topology: Fully discrete, dual differential, high current, short signal path Class A/B

Number of Channels: 5

Power Output
(rated power; THD < 0.01%):
120 watts / channel (4 ohms; all channels driven)
80 watts / channel (8 ohms; all channels driven)

Rated Power Bandwidth (at rated power; 8 Ohm load): 10 Hz to 20 kHz + /- 0.06 dB

Minimum Recommended Load Impedance (each channel): 4 ohms (which equals one 4 ohm load or two paralleled 8 ohm loads per channel)

Frequency Response: 10 Hz to 70 kHz (+ 0 / - 3 dB)

THD + noise: < 0.01%

Signal to Noise Ratio (8 Ohm load):
> 96 dB at 1 watt (A-weighted)
> 117 dB at rated power (A-weighted)

Damping Factor (8 Ohm load): > 500

Speaker Output Connections:
Full-sized 5-way binding posts; one pair per channel x 5

Power Supply:
40,000 uF of storage capacitance

Input sensitivity (for rated power; 8 Ohm load): 850 mV

Gain: 29 dB

Input Connections: Unbalanced (RCA); one per channel

Input Impedance: 47 kOhms

Trigger:
Trigger Input: 5 - 20 V (AC or DC); <10 mA input current required
Trigger Output: 12 VDC; can drive any load up to 50 mA

Power Requirements: 115 VAC or 230 VAC +/- 10% @ 50 / 60 Hz (automatically detected and switched)

Front Panel Controls and Indicators:
Standby; push button (changes color to indicate Standby or On)
Status LEDs (one per channel); illuminate blue for normal operation or red to indicate a fault (may be disabled by rear panel Status LED switch)

Rear Panel Controls:
AC Power switch; rocker switch (switches AC mains power)
Status LEDs switch; small slide switch on left rear (disables front panel Status LEDs and dims Standby button halo lighting)

Protection: The UPA-500 is protected against excessive operating temperature, shorted speaker connections, ground faults, and other common fault conditions. If a fault occurs, the UPA-500 will return to Standby mode, the Standby push button will light amber, and the Status LEDs will flash red.
