The I1 Universal Integrated Amplifier is supplied in standard form equipped with four digital inputs (CH-Link HD, AES/EBU, S/PDIF and TosLink – although a second identical digital input board can be added in the spare chassis slot if you need the extra connections) one set of balanced and two pairs of single-ended analog inputs. The factory-fitted Ethernet Control Board, which allows the unit to be remotely accessed, configured, and controlled via the CH-Control Android App, can be replaced with a complete network streaming capable Ethernet input and a separate, asynchronous USB input card can be added to enable connection of computer sources for file replay. The discrete, fully-complementary analog input boards can be fitted with additional internal circuit blocks that allow owners to convert either or both of the RCA analog inputs into current-sensing MC phono-inputs, complete with switchable replay EQ settings for RIAA, eRIAA, Decca, Columbia, EMI and Teldec (DGG) curves.

Finally, a Clock-Sync board allows you to slave the I1 to external master clocks, or designate its internal clock as the system master. Dominating the interior of the I1 Universal Integrated Amplifier chassis, you’ll find a massive 1000VA transformer that’s more than capable of supporting the 100 watt/channel into 8 Ohms rated output; in combination with the 100,000uF of reservoir capacitance it allows the output stage to handle awkward loudspeaker loads with ease.
