A Compelling Reason to Upgrade Your System's Performance

The Energy 2-channel amplifier will open a dynamic power within your system that you never knew existed. Designed to excel in even the most extreme sonic scenarios, the Energy E2 Amplifier provides a strong foundation to your system's performance, allowing your speakers to sing like never before.

When you use a separate power amplifier, it allows your speakers to realize their true performance potential. The Energy E2 2-Channel Stereo Amplifier is compatible with a wide range of speakers, from 4 Ohm to 16 Ohm, and with 330 Watts per channel at 4 Ohm, you'll have plenty of power; we’re sure your speakers will take nicely to the Energy amp. Using either Balanced or Unbalanced inputs, both channels will ensure a great connection to any preamplifier. The high performance toroidal transformer, and with a Total Harmonic Distortion (THD) of <0.015% ensures a smooth, distortion free sound stage no matter where you’re seated in the room.

Using high current supply capacitors allows for maximum response to sonic transients. Action films come to life as you hear a thunderous explosion - the amp carries the weight, and the large capacitors intervene as short-term electrical storage and "cushion" the peak, allowing the sound effects their own dimension and dynamic. Each Energy amplifier circuit also employs oversized aluminum heat sinks for maximum heat dissipation.

The Energy Amplifier is a flexible, high performance amplifier. It has been designed for maximum performance, ease of use, and installation flexibility for any sized room. By employing cutting-edge technology, the Energy Amp easily powers your speakers at high power levels while at the same time remaining as efficient as possible regardless of volume levels. This maximizes the audio experience without concern for dynamic headroom during complex musical compositions and intense surround sound effects. Don't worry, the Energy Amp does it all with exceptionally refined cosmetics and a sound quality that will satisfy even the most discerning tastes.

Protection Circuits

Overheating Protection Circuit: The power amplifier is intended to operate within a certain temperature range. If the ambient temperature rises excessively or if there is a malfunction, the device will automatically curtail the output when it identifies that the internal temperature has exceeded the specified limit. The operation will only resume once the amplifier's temperature has reverted to the rated level.

DC Current Protection: In cases where the input signal has a considerable DC voltage component, the power amplifier will automatically restrict the DC output voltage to safeguard the loudspeaker drivers from harm.

Overcurrent Protection: Safeguards equipment from damage when there is an unusual rise in output current.

Load Short-Circuit Protection: In instances where the power amplifier's output circuitry goes into a short-circuit state—particularly at elevated volume levels—the load on the amplifier surges dramatically. This leads the amplifier to engage a protection mode to avoid damaging the amplification circuitry.

Power Dynamics

The Energy E2 Amplifier is capable of delivering clear and clean audio across a wide dynamic range which can clearly and accurately articulate the quietest portions, the loudest portions, and everything in between.

XLR & RCA Input

Easily connect the Energy E2 Two Channel Power Amplifier to your PreAmp or Receiver using either Unbalanced RCA Interconnects, or Balanced XLR cables. Simply flip the switch to "XLR" or "RCA" depending on what you are using.

To power up your passive speakers, simply use your speaker cable of choice and connect them to the heavy-duty 5-way gold plated binding post terminals using either; bare wire, banana plugs, spade connectors, round pins, or flat pins.
