The decoded analog audio output produces accurate duplicate of sound which is bit-for-bit identical to the studio master, so listening at home is the ultimate home cinema experience. 

This innovative HDMI digital audio converter can deliver high-quality digital audio through its 7.1 and 5.1 discrete channels via RCA connectors in the back of this HDMI audio processor. Each one of the 8 RCA terminals will be responsible for individual sound track:

  • L for the front left sound
  • R for the front right sound
  • LFE (Low-Frequency Effects) for subwoofer
  • C for the central channel
  • Lb for the rear left channel7.1 Channel Surround Sound Out From AU-HDLB1
  • Rb for the rear right channel
  • Ls for the left surround sound to deliver a directional and more realistic effect
  • Rs for the right surround sound to deliver a directional and more realistic effect

HDMI PCM LPCM 2.0 Audio Decoder
This HDMI audio converter also supports all 2-channel PCM or LPCM 2.0 digital audio from satellite receivers, cable boxes, etc. This PCM audio decoder can provide three simultaneous stereo outputs through:

  • Front Left and Front Right RCA connectors for analog stereo
  • Optical out for digital stereo
  • Coax S/PDIF out for digital stereo

HDMI Dolby DTS To Digital Stereo S/PDIF Converter
This HDMI audio processor also provides audio transcoding function for converting the HDMI audio feed from devices like PS3, HD DVD player, HD cable box and so on to 2-channel digital stereo in optical Toslink or coaxial S/PDIF format. 

This audio processor supports bitstream type in Dolby 5.1, Dolby Digital, DTS, SACD, DVD-Audio and PCM 2 channels, which can be down converted into 2-channel digital stereo through its optical output and coax S/PDIF output at the same time for down stream device such as your favorite amp, audio receiver or powered speaker system for further decoding and broadcasting.

HDMI 1.3 Compliance
This device fully supports HDMI 1.3, which increases the bandwidth in order to support the demands of future HD devices, such as higher resolutions, higher frame rates, etc in both audio/video areas. The increased bandwidth enables higher display resolutions beyond the typical 1920x1080P resolution and improved color depth allowing for more picture quality improvement for the future.

For HDMI audio, HDMI 1.3 compliance is essential for implementing the new high definition audio format. HDMI 1.3 protocol supports lossless compressed digital audio formats for Dolby TrueHD and DTS-HD Master audio. To carry these new HD audio formats, both the input source device and the receiving end must be with HDMI version 1.3 in order to provide the highest sonic performance.

Scalable HDMI 1.2/1.3 ProcessBuilt-In HDMI Amplifier With 225Mhz Bandwidth For 2-In-1 HDMI Amplifier With Audio Decoder Function
This HDMI audio processor offers a great option for users to scale down from their HDMI 1.3 inputs to HDMI 1.2 type. The advantage of this scaling down process is to ease the limitation of the HDMI signal transmission distance and gain higher compatibility with displays of earlier generations since the high bit rate of HDMI 1.3 color depth information will be compromised. 

HDMI 1.2 type signals can be transmitted over far greater distance than HDMI 1.3 feeds and can be recognized and supported by older HDTV displays. During the scale down process, the HDMI 1.2 output from this device retains the same video bandwidth and keeps the same uncompressed digital audio embedded.

Supreme HDMI Booster/Repeater Function
This HDMI audio processor has booster and repeater function built into the circuitry, which will automatically equalizes and compensates for HDMI/ DVI signal loss during the cable run and also extends the cable reach to maximum distance with the same signal quality maintained all the way and delivered to the end HD display. Great for applications requiring long cable runs like digital signage, information kiosks and so on.
