HDMI®1.4a Support for 3D Video and 
Audio Return Channel
The four HDMI 1.4a inputs on the HT-S6305’s A/V
eceiver let you simultaneously connect high-def
r
ources such as a Blu-ray player, a gaming console,
s
nd a cable/satellite tuner. A single output then
a 
sends a pristine signal to your connected high-
esolution display. As the latest version of this
r
onnector, HDMI 1.4a adds the exciting possibilities
c 
of 3D video and an Audio Return Channel. 3D 
video is the next big thing in home entertainment,
ith movie, game, and broadcast content on the
w
ncrease and 3D-compatible displays on the near
i 
horizon. This system also offers the convenience of
n Audio Return Channel via HDMI. Audio content
a
eceived directly by your HDTV’s tuner can be sent
r 
“upstream” to the A/V receiver, without the need 
for a separate S/PDIF audio cable.
Dolby®Pro Logic®IIz Adds New 
Dimensions to Surround Sound
Although the HT-S6305 package comprises a 
.1-channel speaker set, the included A/V receiver
5
ctually handles up to 7.1 speaker channels. By
a 
adding two optional satellite speakers, you can take 
advantage of the front height channels of Dolby 
ro Logic IIz. These channels carry ambient, non-
P 
directional audio that helps immerse you even more
eeply into your movies and games.

192 kHz/24-Bit Burr-Brown DACs 
Improve Jitter Performance to Deliver 
Clearer Sound
High-quality Burr-Brown DACs (PCM1690) work to 
optimize analog audio performance on the 
HT-S6305’s A/V receiver. These DACs perform 
advanced 24-bit signal processing and support 
sampling rates of up to 192 kHz, while displaying 
high resistance to clock jitter and offering a 113 dB 
dynamic range.
Convenient Overlaid On-Screen Display 
via HDMI
Changing your A/V receiver’s settings is now more 
seamless than ever, thanks to Onkyo’s new overlaid 
On-Screen Display (OSD) feature. On-screen set-up 
menus appear overlaid on the video image you’re 
watching. This means you can adjust the settings 
immediately, without having to switch back and forth 
from a blank screen background.
A Suite of Audyssey Technologies for the 
Ideal Listening Environment
(1) Audyssey 2EQ™ tailors multi-channel audio for
your home cinema speaker set-up by measuring 
three room positions and applying a resolution 
filter to the satellite speakers to correct for room 
acoustics.
(2) Audyssey Dynamic Volume
™
automatically 
compensates for volume fluctuations in different 
audio content—for example, during commercial 
breaks—while optimizing the dynamic range.
(3) Audyssey Dynamic EQ
™
maintains a consistent 
bass response, tonal balance, and surround-sound 
effect at different volume levels, so you can enjoy 
the natural dynamics of your content regardless of 
the volume.
