How to Substitute Audio Signals in HDMI Signal Paths

  • PDF

Transformative Engineering (TE) announces the HAI-1 Audio Injector-- a patent-pending device allowing installers to substitute audio in an HDMI signal path.

HAI-1Typical applications include injecting centre channel information so TV speakers can be used as a centre channel, or injecting a local microphone pre-amp signal in an educational or corporate environment to use a TV's internal amplifier and speakers. As a result it eliminates the need and cost for separate amplifier, speakers and installation.

The HAI-1 has 1 HDMI input and 1 output, together with RCA line-level inputs and speaker audio inputs. In centre-channel applications one connects the speaker input to an AV receiver's centre-channel output. The RCA jacks inject line-level mono or stereo signals to the HDMI signal, and can be used to play independent audio sources (such as local microphone or CD/MP3 player) through TV audio systems.

A USB port allows for firmware updates.

The HAI-1 debuts at CEDIA 2015.
