DIGITAL AND ANALOG INPUT OPERATION
LISTENING TO COAXIAL AND OPTICAL DIGITAL INPUTS
COAXIAL and OPTICAL Digital inputs are designed to be connected to the digital outputs of older
or legacy digital products such as CD players, Satellite/cable TV converter boxes, DVD players, Game
consoles, etc., or any device that has a Coaxial or Optical digital output. The Coaxial and Optical
digital inputs can only accept PCM signal up to 24 Bit 192 kHz. Trying to pass a non PCM signal or
anything thing greater than 24 Bit 192 kHz may cause noise or damage to the units.
1. Select the desired input by repeatedly pressing USB/SD/COAX/OPT button on the IR remote
and simply stop on COAXIAL or OPTICAL input as desired.
2. Initiate playback of the corresponding digital source. Refer to the Now Playing Screen section of
this manual to learn about how and what information is displayed on AiOS' front panel.
DID YOU KNOW?
Using Cary Audio's proprietary TruBit™ PCM and DSD Upsampling and conversion technology
allows you to get the most out of the digital input signals during playback for a superior listening
experience. With TruBit™, you can upsample to 1 or 7 different sample rates or 1 of 3 different
PCM to DSD conversion rates. See more on this in the in the PCM to DSD upsampling/conversion
section of the manual.
LISTENING TO ANALOG LINE LEVEL INPUT
The LINE INPUTS are traditional analog inputs you can connect using standard RCA or 3.5mm mini
jack connections.
NOTE: You cannot connect a phono input [record player/turntable] unless it has a built in phono-
preamp or using a separate phono-preamp.
1. Select the desired input by pressing the LINE IN button on the IR remote. Repeatedly pressing
this button will cycle through Line inputs 1, 2, and 3. Simply stop on the input you desire to
listen to.
a. LINE 1 – Standard pair of stereo RCA connections.
b. LINE 2 – Standard pair of stereo RCA connections.
c.
LINE 3 - 3.5mm stereo mini jack. (phone, tablets or other devices that use a 3.5mm
mini jack output)
2. Initiate playback of the corresponding analog (Line level) source. Refer to the Now Playing
Screen section of this manual to learn about how and what information is displayed on AiOS'
front panel.
DID YOU KNOW?
AiOS actually converts your analog line level inputs into a digital signal so Cary Audio can utilize
its proprietary TruBit™ PCM and DSD Upsampling and conversion technology allowing you to get
the most out of the analog input signals during playback for a superior listening experience. This
converts the signal to digital then allows you to upsample it to 1 or 7 different sample rates or 1
of 3 different PCM to DSD conversion rates before converting back to analog for listening. See
more on this in the in the PCM to DSD upsampling/conversion section of the manual. This is also
necessary (and advantageous) so you can listen to your analog line level source through our
Bluetooth SEND feature (See below).
