The AT-HDVS-150-TX-WP, the AT-HDVS-150-TX and the AT-HDVS-150-RX are capable of passing through 2ch audio. If you require the ability to pass multi-channel audio from your sources please use the AT-HDVS-200-TX-WP, AT-HDVS-200-TX and AT-HDVS-200-RX which do have the ability to pass multi-channel audio through the HDMI output of the 200-RX. For both the HDVS-150 and HDVS-200 systems, analog audio can only play back 2ch audio.
