Channel Islands Audio D-500 Mk II

Channel Islands Audio D•500 MKII Monoblock Amplifiers

This pair of like new Channel Islands Audio D•500 MKII Monoblock Amplifiers that have less that 300 hours on them. These D•500 MKIIs shipped to me direct from CIAudio just before Christmas of 2018, and I didn’t open them (I was using and reviewing another set of monoblocks) until April of 2019.

At that point, I used them for the next two months (at an average of about 5 hours a day), until June, 2019, when another set of mono’s came in for review and – well, they stayed.

At that point, they were boxed back up and have not been reopened since. Since I’ve landed on amplifiers that are more than five times more expensive than the D•500 MKIIs, as well having selected yet another set of monos at two and a half times their price, I’ve decided I have no reason to hang on to them. I would like to see them go to a good home and sing rather than sit on a shelf in their packing boxes. They TRULY are in AS NEW condition, electrically and cosmetically.

These are exceptionally powerful and dynamic amplifiers, with the ability to masterfully control virtually any loudspeaker out there, especially those that are current hungry or particularly challenging to drive, like ELSs or Planar-Dynamics.

Channel Islands Audio D•500 MKII Monoblock Amplifiers

Chassis Design

The monaural design is housed in a beautiful new machined aluminum chassis with heavy steel frame plate to support the massive power transformer. Non-magnetic stainless-steel hardware and highest quality parts are used throughout. Adjustable 5-way binding posts are used for loudspeaker connection and can be configured for horizontal or vertical cable entry.

Power Management

Our SmoothStart™ and XDC•2 circuits control AC power, while our DC board supplies the various output voltages required by the audio circuit. Signal input is handled by panel-mounted jacks for both single-ended RCA and balanced XLR connections. Turn-on is accomplished by the front-panel mute/play button, or remote 12v trigger (when used with PLC•1 MKII or other makes with this function)

Audio Circuit

The audio circuit consists of an advanced full bridge UcD design (a Bruno Putzeys patented circuit) for life-like music reproduction and offers unsurpassed performance, reliability, and efficiency. Due to the large heat-sink area and high efficiency, D•500 remains cool to the touch even at continuous high output levels. Protection from over-voltage and short-circuit conditions are provided.
