The Kii CONTROL offers three additional digital inputs for the Kii THREE: Coax SPDIF, Optical TOSLINK and USB (up to PCM 24/384kHz and DSD64/DSD128 on USB).
All inputs are located on the backside connector panel and can be activated with the touch buttons located around the volume knob. A dedicated input button (labeled XLR) will switch to the existing hardware input on the speaker itself, which you can continue to use as analog or digital input. The Kii Control connects with a single included CAT6 cable and is also powered through this connection. No additional power supply is necessary.
The Kii Control enables lossless volume control inside the DSP of the Kii Threes, keeping the signal path of the system as transparent as possible.
