Transformative Engineering rolls out patent-pending audio injector for HDMI
Electronics manufacturer Transformative Engineering announced it has developed a patent-pending device that will allow users to substitute audio in an HDMI signal path.
TE’s HAI-1 has one HDMI input and one output, stereo RCA line-level inputs, and high-level speaker audio inputs. TE explained some of the potential uses for the device in a statement:
Typical applications include injecting the center channel information so a TV's speakers can be used as the center channel. The resultant effect is remarkable and eliminates the need for a separate center channel speaker. Another use may be injecting a local microphone preamp signal in an educational or corporate environment to utilize the TV's internal amplifier and speakers. This eliminates the need and cost of another separate amplifier, speakers, and installation.
Further, the RCA jacks are used to inject line-level mono or stereo speakers into the HDMI signal. They can be used to play independent audio sources like a local microphone or a CD/MP3 player, through the TV’s audio system. The HAI-1 also has a USB port for firmware updates.
Transformative Engineering said the HAI-1 is now available from TE reps and distributors, or directly from the company. Its suggested retail price is $199.
