E•200S 2-Channel (Stereo) Amplifier


Our E Series Amplifiers represent the latest in Class D amplifier technology.

SKU: N/A Category:



  • Flat frequency response and phase into any conventional speaker load
  • Low distortion which is flat vs frequency
  • Ultra low output impedance for excellent control of the loudspeaker
  • High efficiency, which results in lower power consumption, low operating temperature, and high reliability
  • Compact & light weight package

Power Management

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.

Owners Manual


What makes the CIA E•200S different from any other amp that uses UcD or Ncore amp modules? The magic occurs in the input stages and power supplies. Imagine the mating of an incredibly quiet tube-amp dad and a very powerful, solid-state, class-A mom. Their child might sound like the CIA E•200S. I can’t wait to hear Channel Islands Audio’s Ncore-based E•125S. This company knows how to design an amplifier that achieves truly exceptional sound for a reasonable price… READ MORE
