  • Compact & light weight package

Power Management

E100 Rear Sm

The internal design of the amplifier consists of a power control circuit consuming less than a 1⁄2 watt of power. When turned on, this circuit feeds dual mono switched-mode power supplies... one for each channel. The on/off function can be controlled by the front panel switch or via the 12V trigger input on the rear panel.

Audio Circuit

Input signals are connected via rear panel mounted RCA (single-ended) or XLR (balanced) jacks into individual differential pre-stage circuits with on-board regulation. Output of this circuit is then coupled to updated UcD Class D stages. These new & improved output circuits incorporate many advances found in the Hypex NCore technology.

Amplifier outputs are conveniently located on the rear panel. Speaker connections can be made in a variety of ways via the insulated 5-way binding posts.

The compact machined aluminum chassis provides heat dissipation for the direct-mounted power supply and audio output circuits. Due to the high efficiency of the circuits, the chassis will only be warm to the touch under normal conditions.


The E series amplifiers are equipped with a variety of fault protections including DC, over-voltage, and short-circuit. AC Mains Fuse protection is also provided and easily accessible above the power inlet.
