1. Introduction
1.1 Introduction to TL-AD-HD
The TL-AD-HD2 4K UHD HDMI with Dolby® Digital/DTS® Stereo Audio Decoder
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 (optical and coaxial) as well as analog RCA connections. It can
also support the pass-through of HD and standard bitstream formats as well as LPCM
7.1 with audio sampling rates up to 192 kHz if needed.
If the connected display supports ARC (Audio Return Channel), and has it enabled, then
this unit can extract the ARC audio and output it via all available audio outputs. Both the
input and output HDMI ports support 4K UHD resolutions up to 4K@60Hz (YUV 4:4:4,
8-bit). Built in EDID management support allows the user select from multiple EDIDs
and, with the use of optional PC software, to edit, upload and download EDID files.
1.2 Features
• HDMI input and output with 18Gbps (600MHz) 4K UHD support
• DVI 1.0 compliant with the use of an HDMI-DVI adaptor
• HDCP 1.4 and 2.2 compliant
• Supports HD resolutions up to 3840x2160@60 Hz (YUV 4:4:4, 8-bit) &
4096x2160@60 Hz (YUV 4:4:4, 8-bit)
• Supports 48-bit Deep Color up to 1080p60
• Supports pass-through of LPCM 7.1, bitstream and HD bitstream audio formats
over HDMI
• Embedded Dolby Digital Decoder technology
• Embedded DTS 2.0 + Digital Out Decoder technology
• Integrated digital interpolation filter and Digital-to-Analog Converter (DAC)
• Supports LPCM sampling rates up to 96kHz.
• Supports Dolby Digital sampling rates up to 48kHz.
• Supports DTS sampling rates up to 96kHz.
• Simultaneous audio output via HDMI, analog stereo, Coaxial and Optical.

• Supports coaxial and optical audio sampling rates up to 96kHz.
• Support extracting HDMI audio signal from HDTV’s ARC connection.
• Provides EDID management with EDID bypass and 1 user modifiable EDID
• PC based EDID management tool support
• Supports RS-232 style control via a Virtual COM port over USB
Note: 4K UHD sources or equivalently high-bandwidth signals require an appropriate
compatible display and HDMI cables in order to achieve the best image quality. The use of
“Premium High-Speed HDMI” cables is highly recommended.

2. Panel Description
2.1 Front Panel
1) POWER LED: This LED will illuminate to indicate the unit is on and receiving
power.
2) PCM LED: This LED will illuminate when LPCM audio is detected on the HDMI
input. If the ARC function is active, this LED will illuminate when LPCM is detected
from the ARC source.
3) dts LED: This LED will illuminate when DTS 2.0+Digital audio is detected on the
HDMI input. If the ARC function is active, this LED will illuminate when DTS
2.0+Digital audio is detected from the ARC source.
4) Dolby LED: This LED will illuminate when Dolby Digital audio is detected on the
HDMI input. If the ARC function is active, this LED will illuminate when Dolby
Digital audio is detected from the ARC source.
5) ARC LED/ ARC Button: Pressing this button will enable/disable the unit’s ARC
(Audio Return Channel) functionality. When the ARC function 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 function is not enabled the LED will
remain off.
Note: Please ensure that the connected display supports ARC and that the display’s ARC
function is enabled before activating the ARC functionality of this unit. Failure to meet
these requirements will result in no audio output.

HDMI port. Moving the switch to the left 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.
7) SPDIF BYPASS/2CH: This switch controls the audio output format for the S/PDIF
audio output ports (Optical and Coaxial). Moving the switch to the left 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.
8) EDID: This switch controls which EDID is sent to the connected HDMI input
device. Moving the switch to the left sets it to “STD” mode which will use the
