3.3 Audio Configuration
3.3.1 General
Select AUDIO INPUT TYPE either with the SELECT button on the Front Panel or
on the GUI. In ANALOG MODE, there are two user selectable sampling rates.
The recommended value is 48 kHz for good audio quality, but 32 kHz is available
for increased delay time.
 The SPDIF Digital Input supports the common sampling rates used by
CD, DVD, DAT and Blu-Ray Disc (BD) Players: 32 kHz, 44.1 kHz, 48
kHz and 96 kHz.
 The Digital Input supports uncompressed audio 2 channel Linear PCM
(LPCM), which is automatically converted to analog output.
 The Digital Input supports stereo or mult-ichannel compressed audio
(encoded bitstreams formats) like Dolby Digital Stereo, Dolby Digital
Surround (5.1) and DTS-CD Surround (5.1) and DTS Surround (5.1).
 The AD-340 auto-detect sampling rates and the encoded Bitstream
formats for digital inputs. The SPDIF indicators also show SPDIF
input errors and whether the PLL is locked or unlocked.

Both analog and digital audio are output simultaneously for analog input and
LPCM Digital Inputs.
The Encoded Bitstreams Formats must be decoded by an A/V receiver or similar
audio equipment with embedded Dolby Digital or DTS decoder for full 5.1
channel functions. (Note: Analog Audio is auto-muted when the AD-340 detects
a non-PCM bitstream).
 Press the SELECT button for Audio Input Type Selection. LEDs
indicate if ANALOG or DIGITAL audio input is active.
