HD12DB

Quick Reference Guide

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.

FEATURES:

• 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 1 x 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 2 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

HD12DB QUICK REFERENCE GUIDE

EDID (Extended Display Identification Data) is a data
structure that is used between a display and a source.
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 a digital
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 higher­definition 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.
