HDMI Splitter with Audio Extraction SpeaKa Professional SP-HDS-300 1x2 4K

The SpeaKa Professional SP-HDS-300 1x2 HDMI Splitter with Audio Extraction is designed to duplicate a single HDMI source to two HDMI displays while providing a separate analog or digital audio output. Supporting 4K video, this splitter is intended for environments that need a mirrored video signal together with an extracted audio feed for connection to external sound systems, recorders or PA equipment. The unit is compact and intended for integration into presentation setups, digital signage, home AV systems and recording workflows.

Advantages

The device outputs the same HDMI video to two displays simultaneously while extracting audio to a dedicated output, enabling independent audio routing without altering the video signal. Support for 4K resolution ensures compatibility with high-definition sources and modern displays. The splitter simplifies setups by reducing the need for additional converters or separate audio taps and provides a stable, single-source distribution for both video and audio channels.

Suitable for

• Presentations and meeting rooms where the same image is required on multiple screens with separate audio to a sound system
• Retail or public digital signage installations requiring mirrored displays and centralized audio
• Home AV setups that need to send a 4K signal to multiple TVs while routing audio to an amplifier or soundbar
• Recording or streaming workflows that demand an independent audio feed from an HDMI source

When it may not be suitable

This splitter duplicates the incoming HDMI video to two outputs but does not perform signal scaling or format conversion beyond standard HDMI pass-through; therefore it may not be suitable when different displays require different resolutions or when advanced EDID management is required. It also provides audio extraction but may not replace dedicated multichannel audio processors if complex mixing, up/down mixing or advanced DSP is needed.

Key specifications

• Function: 1 input to 2 output HDMI splitter with audio extraction
• Maximum video support: 4K resolution (Ultra HD)
• Audio extraction: dedicated audio output for external sound systems or recorders
• Outputs: two HDMI video outputs plus one audio output (analog or digital as implemented)
• Use case: video duplication and separate audio feed for AV systems, signage, recording

How to use

Connect the HDMI source (laptop, media player, set-top box) to the splitter's HDMI input. Use HDMI cables to connect the two HDMI outputs to displays or projectors. Connect the audio output from the splitter to an external amplifier, powered speakers or an audio recorder using the appropriate cable for the provided audio connector. Power the unit according to the supplied adapter and verify that the source and displays are set to compatible HDMI modes. Check audio routing on your source device if the extracted audio is not immediately present.

What to consider before purchase

• Ensure connected displays support the same resolution and refresh rate required, as the splitter duplicates a single output
• Confirm the type of audio output provided (analog or digital) matches your amplifier or recorder inputs
• Verify power requirements and available space for mounting the compact unit

Usage recommendations

Use high-quality HDMI cables rated for 4K to maintain signal integrity. When connecting multiple displays, set the source resolution to a common denominator supported by both displays. If audio is critical for recording or PA use, perform an audio check before live events to confirm levels and compatibility between the extracted audio output and your downstream device.
