Frequently Asked Questions - HD11AU Blustream

How do I extract audio from HDMI using the HD11AU?

Set the Mode DIP switch 0 to 0 (de-embed mode). Connect HDMI source to HDMI IN, and display to HDMI OUT. Audio is output simultaneously via Coaxial OUT and L/R OUT (analogue). Ensure source audio is PCM for analogue output.

How do I embed analogue audio into HDMI?

Set Mode DIP switch 0 to 1 (embed mode). Connect an analogue audio source (e.g., microphone) to L/R IN, and HDMI source to HDMI IN. The HDMI output will carry video from the source and audio from the analogue input, replacing the original HDMI audio.

Can the HD11AU output audio without a display connected?

Yes. Set Mode DIP switch 1 to 1 (force HPD high). This forces the HDMI input to think a display is connected, allowing audio extraction even with no display attached.

What is the maximum video resolution supported?

The HD11AU supports up to 4K@60Hz 4:2:0 and 3D video. It is HDCP 1.4 compliant.

How do I configure the EDID settings?

Use DIP switches 3,2,1,0 (labeled EDID on the side panel). There are 16 presets, including copying the display's EDID, fixed resolutions (1080p, 1080i, 4K60 4:2:0) with various audio channel configurations, and DVI modes with no audio.

What type of power supply does the HD11AU need?

It requires a 5V DC, 1A power supply. The included adapter is suitable. Use a surge protector for added safety.

Can I use the coaxial and analogue audio outputs simultaneously?

Yes. Both outputs are active concurrently in de-embed mode. The coaxial output carries digital audio (up to 5.1ch), while the analogue output provides 2ch PCM only.

What are the audio input and output connectors?

Audio input: 1x 3.5mm stereo jack for analogue left/right. Audio outputs: 1x coaxial digital (RCA) and 1x 3.5mm stereo jack for analogue left/right.

How do I clean and maintain the HD11AU?

Use a soft, dry cloth to clean the unit. Do not use alcohol, paint thinner, or benzene, as they may damage the surface.

What is the purpose of the Mode DIP switches?

Mode switch 0 selects between audio de-embed (0) and audio embed (1). Mode switch 1 controls HDMI HPD: 0 makes input HPD follow output HPD; 1 forces input HPD high for operation without a display.

Introduction

Our HD11AU is the perfect solution for either de-embedding or embedding audio within the HDMI signal path. This solution allows you to breakout up to 5.1ch audio signals.

Connect the HD11AU between your source and display via HDMI, then select whether de-embedding or embedding audio is required.

FEATURES:

• Extract audio from the HDMI video input
• Extract audio with or without an actual display connected
• Provides both coaxial digital and analogue left / right audio outputs concurrently
• Can remove the audio from the HDMI input signal and embed analogue left / right audio to the HDMI output signal
• Analogue left / right out supports 2ch PCM input signal only
  • Support 3D video & 4K 60Hz 4:2:0
• HDCP 1.4 compatible
• Small compact size

Panel Descriptions

Front Panel

1 Left / Right Analogue audio input - 3.5mm Stereo jack
2 HDMI input
3 Power port – Use supplied 5V / 1A DC adaptor
4 HDMI input status – Lit when HDMI signal detected
5 Power status – Lit when unit is powered
6 Coaxial digital output – Used when audio is de-embedded from HDMI

Back Panel

7 HDMI output
8 Left / Right Analogue audio output. Extract audio from HDMI input and convert to 2ch. NOTE: Source audio must be PCM
9 HDMI output status – Lit when HDMI signal detected

Side Panel

10 EDID management DIP switches – See adjacent table for settings
11 Mode Dip switches – See information below for mode settings

Mode Selection DIP Switches

Dip Switch 1 = 0: Input HDMI HPD (Hot Plug Detected depends on output HDMI HPD

Dip Switch 1 = 1: Input HDMI HPD forced high (for installations where no output device is connected)

Dip Switch 0 = 0: HDMI audio de-embed mode

Dip Switch 0 = 1: Analogue audio embed mode - removes the audio from HDMI input signal and embeds the analogue L/R audio input onto the HDMI output signal
