The GefenTV HDMI to HDMI Plus Audio Converter
The GefenTV HDMI to HDMI Audio Converter is a product that takes a Hi Def
source using HDMI and outputs it to an HDTV display using HDMI and, in addi-
tion, up to 8 channels of LPCM audio output through eight RCA connectors. Also,
if a Bitstream audio is desired it outputs this to an Optical digital connector.
Additional features include switchable audio selections between auto mode and
manual mode affording further selection between two-channel audio only, multi-
channel bitstream and 7.1 LPCM audio.
How It Works
Connect a Hi Def source to the GefenTV HDMI to HDMI Audio Converter’s input
with the included HDMI cable. Connect another HDMI cable from the output of
the Converter to an HDTV display. Connect an optical audio cable from the Con-
verter to an external amplifier. Alternatively connect an amplifier to the 8 channel
RCA connectors. Finally connect the 5V DC power supply to the locking connec-
tor and to an electric outlet.
See pages 4 and 5 for further information about the switches on the front panel.

SUPPORTED AUDIO FORMATS
The Audio Selector Switches
The audio output supports uncompressed LPCM 7.1 and lossless compressed
digital Bitstream (Dolby TrueHD, Dolby Digital Plus and DTS-HD Master Audio).
There are two switches on the front of the unit to the right of the power LED. (See
Panel Layout and Description on pages 6 and 7.) The switch at the left makes
changes to the input audio and the right switch changes from “Auto” to “Manual.”
Unless the right-hand switch is set to “Manual,” the audio selector switch will
not change the audio format from what is coming from the HDMI input. When
this switch is set to “Manual” the audio portion is changed according to what has
been selected.
Determining the Supported Audio Formats
The unit passes audio to its outputs according to the type of signal. See the table
below:
AUDIO FORMAT HDMI OUT TOSLINK 8CH-RCA
2 Channel LPCM x x x (FR, FL only)
5.1 Channel LPCM x x
7.1 Channel LPCM x x

A Note About Audio Processing in the GefenTV HDMI to HDMI Plus Audio
Converter:
When “2.1” is selected, the audio signal is output to the FR and FL only.
When “5.1 / 7.1” is selected audio is output from the “Multi-CH” output. When
“Bitstream” is selected, the signal is output from the “Optical” output only. The
signal output from TOSLINK should be LPCM 2 ch, AC3 5.1, or DTS 5.1.
The unit supports uncompressed digital LPCM 7.1, 5.1 or 2 channels and
compressed digital Bitstream (Dolby TrueHD, Dolby Digital Plus and DTS-HD
Master Audio) through the HDMI input and the RCA output.
It only supports Hi Res Audio via HDMI. It does not decode Hi Res Audio.

AUDIO PROCESSING
Audio Mode Selection:
AUTO MODE:
To use this mode, set the switch on the front panel to the AUTO position. The
converter will output the highest common video resolution and audio capability
according to the EDID data it retrieves from the connected display device.
MANUAL MODE
To use this mode, set the Switch on the front panel to the MANUAL position.
This mode will use a preset EDID that is stored in the converter from the factory.
This pre-programmed standard EDID data structure is compatible with most A/V
display devices. All resolutions and audio formats specified in this EDID will be
passed to the source device, allowing the user to set the video resolution and
audio capabilty.
