Channel Islands D-100 Amplifier

We don't have any plans to make an all black version, but it could be done at an extra cost (and lead time). Give us a call if you need more info.

We're working on a RF remote controlled passive preamp with 4 inputs, a tape loop and 2 pair of output jacks. I don't believe in the pass-thru idea because if you play your hifi and forget you're in HT bypass, the volume is full blast and can cause damage. With a remote passive, just turn the volume all the way up when going into the home theater system.

D-200 is getting close to production. I'll post details and performance graphs in a day or two at our Audio Circle Forum.

In reply to Bailey...
It all depends on how you want to set up the system(s).

The new preamp will have 2 pair of outputs, what we could do is make one pair a standard variable output through the volume control, and the 2nd pair could be configured for "bypass"(taken from the input selector switch before the volume control)or could be a 2nd pair of variable outputs(after the volume control). This would most likely be done by a set of internal jumpers.

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.

New D-200 preliminary info is now posted here

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.
