This Digitalinx DL-HDDM21 is an HDMI Dolby Digital & DTS Stereo Decoder that supports the transmission
of high bandwidth (18Gbps) video and allows the associated audio signal to be simultaneously extracted
and split to both digital and analog audio outputs, providing high quality audio and video performance.
This unit can decode standard Dolby Digital & DTS formats up to 5.1 and output the audio as stereo
(LPCM 2.0) over HDMI, S/PDIF (opcal and coaxial) and analog RCA connecons. If the connected
display supports ARC (Audio Return Channel), and has it enabled, then the DL-HDDM21 can extract the
ARC audio and route to all available audio outputs.
Both the input and output HDMI ports support 4K UHD resoluons up to 4K@60Hz (4:4:4, 8-bit).
Built-in EDID management support allows the user to select from mulple EDIDs and, with the use of
oponal PC soware, to upload, download, or edit EDID les.

1. POWER LED
• Illuminates when the unit is on and receiving power.
2. PCM LED
• Illuminates when LPCM audio is detected on the HDMI input. If the ARC funcon is acve, this
LED will illuminate when LPCM is detected from the ARC source.
3. DTS LED
• Illuminates when DTS 2.0+Digital audio is detected on the HDMI input. If the ARC funcon is
acve, this LED will illuminate when DTS 2.0+Digital audio is detected from the ARC source.
4. DOLBY DIGITAL LED
• Illuminates when Dolby Digital audio is detected on the HDMI input. If the ARC funcon is
acve, this LED will illuminate when Dolby Digital audio is detected from the ARC source.
5. ARC:
• Pressing the this buon will enable/disable the unit’s ARC (Audio Return Channel) funconality.
When the ARC funcon is enabled, the LED will illuminate and ARC audio sent back from the
connected display will be output over all local audio outputs. When the ARC funcon is not
enabled the LED will remain o.
Note: Please ensure that the connected display supports ARC and that the display’s ARC funcon
is enabled before acvang the ARC funconality of this unit. Failure to meet these requirements
will result in no audio output.

•OPTICAL; Digital mul-channel HD audio output
4. HDMI AUDIO BYPASS/2CH
•Controls the audio output format for the HDMI port. Moving the switch to the le sets it to
“BYPASS” which allows audio to pass unchanged from the HDMI input port. Moving the switch
to the right sets it to “2CH” which enables decoding Dolby Digital and DTS audio from the HDMI
input and down-mixing it to LPCM 2.0.
5. S/PDIF BYPASS/2CH:
•Controls the audio output format for the S/PDIF audio output ports (Opcal and Coaxial).
Moving the switch to the le sets it to “BYPASS” which allows audio to pass unchanged from the
HDMI input port. Moving the switch to the right sets it to “2CH” which enables decoding Dolby
Digital and DTS audio from the HDMI input and down-mixing it to LPCM 2.0.
6. EDID STD/TV
•Controls which EDID is sent to the connected HDMI input device. Moving the switch to the le
sets it to “STD” mode which will use the internal (user) EDID. Moving the switch to the right sets
it to “TV” mode which will pass the EDID from the connected display device to the HDMI input
device Note: By default the “STD” EDID contains video resoluon support up to 1080p@60Hz and
audio support including LPCM 2.0 up to 96kHz, Dolby Digital (5.1 channel) and DTS (5.1 channel).
7. SERVICE - USB port for EDID management, control and rmware use.
