Introduction
The Blustream HD12DB-V2 has been designed to convert and downmix embedded 7.1ch Dolby Audio or DTS Audio within a HDMI signal, into a stereo 2ch signal available on HDMI, optical and analogue audio outputs. The HD12DB-V2 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 down-conversion of 4K 60Hz 4:4:4 video down to 1080p. This provides the perfect cost effective 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 7.1ch zones with multiple output resolution requirements
FEATURES:
- Features an in-built DAC (Digital to Analogue audio converter) that converts 7.1ch Dolby Audio or DTS Audio to a stereo 2ch signal available on HDMI, optical and analogue audio outputs concurrently
- Supports multi channel audio input formats up to Dolby Atmos and DTS:X
- 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 7.1ch Dolby Audio & DTS Audio
- HDMI output 2 features a video downconversion from 4K down to 1080p
- HDMI audio breakout to downmixed analogue L/R audio and downmixed optical digital outputs concurrently
- HDCP 2.2 compliant with advanced EDID management.

EDID Management Dip-switches
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-V2 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-V2 scales to.
To change the EDID settings move the EDID dipswitches as required on the front
panel of the unit.
Please see adjacent table for settings.
Note: You must power-cycle the HD12DB-V2 after changes have been made in order for the EDID settings to update.
