Hi, is the 'CI' indicated on the front panel of the unit next to 2808? Just curious because i dont have it mine although the box has it with 2808ci. I bought mine locally 2years ago and never thought about it until now.
If your unit came from the US (110 volts), it's likely a CI unit.
Let me be clearer about what "CI" means in practice -- It means you can have your Denon AVR calibrated by a professional using Audyssey Pro. That is basically a much more sophisticated version of the Audyssey MultEQ calibration because it uses an individually calibrated and very accurate microphone, can do 32 mic positions, can select the target curve (depending mainly on the size of your room) and can create a filter which is optimized for your specific crossover.
In order to do this, you need a professional Audyssey calibrator who will purchase the license for you and then do the actual calibration, using his equipment. The cost of the license is $150, cost of calibration varies.
Insofar as I know, I am the only Audyssey Pro calibrator in the Philippines.
