The Blustream HD12DB has been designed to convert and downmix embedded
5.1ch Dolby Audio or DTS Audio within a HDMI signal into a stereo 2ch signal
available on HDMI, optical and analogue audio outputs. The HD12DB features
a HDMI loop out to pass the original video and multi-channel embedded audio
signal to compatible equipment, with a second HDMI output featuring video
scaling of up to 4K 60Hz 4:4:4 video to various lower resolution video formats.
This provides the perfect cost eective solution for ensuring that 4K UHD video
and multi-channel audio can be distributed around a multi-room system where
there are a mixture of 2ch and 5.1ch zones with multiple output resolution
requirements.
Introduction
• Features an in-built DAC (Digital to Analogue audio Converter) that converts 5.1ch Dolby Audio or DTS Audio to a
stereo 2ch signal available on HDMI, optical and analogue audio outputs concurrently
• Supports the following audio input formats: Dolby 5.1, DTS-ES 6.1, DD+5.1, DD+2.0, PCM 5.1, PCM 2.0*
• Features 1x HDMI input supporting 4K UHD video (4K 60Hz 4:4:4) that is replicated to 2x HDMI outputs
• HDMI loop out will replicate the HDMI input signal up to 4K 60Hz 4:4:4 and 5.1ch Dolby Audio & DTS Audio
• HDMI output 1 features a video scaler allowing the resolution to be set to the following formats:
- 3840x2160@60Hz - 4096x2160@60Hz
- 3840x2160@50Hz - 4096x2160@50Hz
- 3840x2160@30Hz - 4096x2160@30Hz
- 3840x2160@25Hz - 4096x2160@25Hz
- 1920x1080@60Hz - 1920x1200@60Hz
- 1920x1080@50Hz - 1680x1050@60Hz
- 1280x720@60Hz - 1024x768@60Hz
- 1280x720@50Hz
• HDMI audio breakout to downmixed analogue L/R audio and downmixed optical digital outputs concurrently
• HDCP 2.2 compliant with advanced EDID management
*Note: this product does not support decoding of DTS CD bitstreams. Playback of this format may produce undesirable noise.

EDID Management Dip-switches
EDID (Extended Display Identification Data) is a data structure that
is used between a display and asource. This data is used by the
source to find out what audio and video resolutions are supported
by the display then from this information the source will determine
what the best resolution is to output.
While the objective of EDID is to make connecting adigital display
to a source a simple plug and play procedure issues do arise when
multiple displays or video matrix switching is introduced because
of the increased number of variables.
The HD12DB will act as an ‘end point’ in the HDMI signal path.
Using the EDID dip-switches predetermines the video resolution
and audio format of the source regardless of the video output
resolution that the HD12DB scales to.
To change the EDID settings move the EDID dip-switches as
required on the front panel of the unit. Please see adjacent
table for settings.
Note: You must power-cycle the HD12DB aer changes have
been made in order for the EDID settings to update.
Output 2 ‘Scaler’ Dip-switches
The HD12DB is ideal for installations that have two displays
capable of supporting dierent video formats. Installing the
HD12DB will allow those displays only capable of supporting
lower video resolutions to receive scaled 4K video (via HDMI
output 2) while still showing maximum original 4K resolution
on the higher-definition displays (via HDMI output 1).
Using the EDID settings (as above) the source can be
instructed to output a 4K 60Hz signal (or lower format if
required). The HD12DB will scale the HDMI input signal to a
selected output resolution on HDMI output 2 using the Scaler
dip-switches on the rear panel. The HD12DB will continue to
pass-through the original 4K 60Hz video signal onto HDMI
output 1 without any scaling. Please see adjacent table for
settings.
The HD12DB is capable of automatically managing HDCP
of the scaled output to ensure HDCP compatibity where
required.
Note: You must power-cycle the HD12DB aer changes have
been made in order for the Scaler settings to update.
# Smart Output (Scaler DIP 0000) mode looks at the EDID
of the display connected to HDMI output 2 and scales the
picture to the most suitable resolution based on this EDID
information.
