Digital Audio Outputs (Coaxial Jack and Cable) The Digital Audio Coaxial cable provides excellent quality audio, second only to the Digital Audio Optical cable. S-Video Jack and Cable S-Video jacks and cables provide the best non-HD picture quality. You will still need to connect the left and right audio cables to the TV, or optical audio cable to your stereo, because the S-Video cable only carries the picture signal, not sound. A separate audio connection is also required, using either Digital Audio Optical cable or the audio portion of an A/V cable. Audio/Video (A/V) Jack and Cable Audio/Video (A/V) cables provide very good picture quality and stereo sound. The video cable should be used if you don't have HDMI, component or S-Video cables, or your TV does not have HDMI, component or S-Video jacks. The audio cable may be used if you have connected your TV with S-Video or Component cables, which don't provide audio signals. The DIRECTV Receiver's A/V jacks are color coded (yellow for video, red for right audio and white for left audio). If your TV has only one input for audio (mono), connect it to the left (white) audio jack on the DIRECTV Receiver. Telephone Jack and Cord The telephone line cord connects your DIRECTV Plus HD DVR to a land-based telephone line. The phone line connection is used to periodically call DIRECTV. This connection is required for sports package subscriptions and for purchasing Pay Per View movies and events. You will need an RJ11-type modulator jack (the most common type of phone jack). Note: Do not connect your receiver to a digital PBX phone system - doing so may permanently damage your equipment and void your warranty. Warning 66 Do not connect your receiver (or any other equipment such as a TV or VCR) to the AC power supply until you have properly connected all the other cables S-Video Jack R L Video Phone Jack Note: Not all cables come with your digital satellite receiver; you may need to purchase additional cables, depending on your setup.
