The AV amplifier which equips the HDMI input/output terminal of version 1.3a correspondence. As for the installed capacity of VSA-AX4H 220W×7ch (6Ω) with as for HDMI input 4 systems, as for VSA-AX2AH 200W×7ch (6Ω) with HDMI input 3 system. Together THX SELECT 2 recognition is acquired.
Simultaneously with plasma television “KURO series” it announced VSA-AX4H, “VSA-LX70” and function/efficiency being common, it designates the body color as the silver. As for the difference of VSA-AX4AH and VSA-AX2AH the number of installed capacities and HDMI input, the presence of USB and presence etc of trigger terminal.
It corresponds to the decoding DTS-HD Master Audio and Dolby TrueHD which are adopted for Blu-ray Disc and HD DVD video. By the fact that these audio formats are combined with the bitstream output enable player, decoding on the AV amplifier side is possible. Dolby digital plus and DTS EXPRESS (to the sub audio of BD/HD DVD or the format which supports largest 5.1ch sound low with fixed data transfer system of bit rate) it corresponds for broadcast and the one for memory audio etc.

In addition, the case where the aural signal is distributed to each unit with network inside the speaker measurement/analyzing the time gap, it revises it 
loads also “[hurubando] [hueizukontororu]”. Be able to revise also the group delay quality difference during the slipping and the speaker between unit simultaneously, you say that the ideal stereo/it can do [saraundo] playback.
It loads also automatic sound field revision function “Advanced MCACC”. Do the range measurement to the speaker, it can actualize more accurate distance revision at the 1cm unit. The microphone of attachment is installed, automatic gaging/revises also “automatic MCACC” mode has at buttons 1.
It supports also Deep Color of HDMI Ver.1.3a. The color depth of maximum 12bit can be indicated transmission/. SD image HDMI equipping the rise scaling function which can be output at most 1080p. DCDi of [huarojiya] is adopted to the image circuit, high speed I/P conversion is actualized.
Adopting 3 dimensional space frame to the frame. As for the power amplifier you say that low unnecessary radiation was decreased with impedance conversion and module minimization, adopting the “direct energy power engine”. 24bit/192kHz correspondence DAC of δσ type is loaded. Adjusting to the sound source, minimum signal processing it selects it loads also “stream direct” automatically.
Building in the decoder of Windows Media Audio 9 Professional. The compressed sound source of MP3 and the like is revised loads also “[saundoretoriba]”. It equips also the private terminal for iPod connection.
Besides the fact that with VSA-AX4AH, it has the USB terminal, it retained it can play back the music file which is done in USB memory and the audio player, it equips also the Ethernet terminal. MP3, WMA, AAC, FLAC and WAV inside PC (linear PCM) it can play back the file by way of the network with DLNA client function “Home Media Gallery”.
