Channel Islands D-100 Amplifier

The D-100's have 27,340uF of power supply capacitance, which is really overkill for this type of design. The efficiency of the Class D section does not require huge banks of filter capacitors like a standard class AB design.

No amp truly doubles it power output into half impedance due to various losses. The ones who claim this are probably slightly under rating the 8 ohm perfomance. The D-100 and
D-200 will output much more power into lower loads. The current limiting is really what determines this in our design.

I can thank Psychicanimal for my first exposure to Channel Islands last Summer.
I brought my modded mono amps & tube Dac over to his place and was shocked at how well his little Channel Island setup sounded.
These D-100's & (soon D-200's) must be really special.

New D-200 preliminary info is now posted here

I chatted with a happy customer of CIA (cant remember where) a couple months ago and he was very happy with his new 40 watt monoblocks.
Could any noise be coming from the 40-100 or 200 watt amp such as a "hum" or "anything" under normal operating conditions?

Thanks a lot.....Pat

All of our amplifiers use custom made transformers and are very quiet mechanically. All models are available in 100v (for Japan), 120v, and 220-240v/50~60hz (Europe, Asia, Australia).
Hum in the audio(heard through the loudspeakers)is usually caused by ground loops, poor shielding, system wiring, etc.
