  • Page 15: Ir Remote Configuration

    IR REMOTE CONFIGURATION How to Resolve IR Code Conflicts In the event that IR commands from other remote controls interfere with the supplied IR Remote Control unit, changing the IR Remote Control’s IR channel will fix the problem. The IR Remote Control unit has a bank of DIP switches used for setting the IR channel. The DIP switch bank is located underneath the battery cover. Left: Picture of the opened rear battery compartment of the IR remote showing the exposed DIP Switch bank between the battery chambers. Corresponding DIP Switch Settings for each IR Channel IR Channel 0 (default) IR Channel 1 IR Channel 2 IR Channel 3 It is important that the IR channel on the Remote Control unit, matches the IR channel set on the 4x1 HD Switcher w/ Audio Decoding. For example, if both DIP switches on the IR Remote Control unit are set to IR channel 0 (both DIP switches down), then the 4x1 HD Switcher w/ Audio Decoding must also be set to IR channel 0. See page 38 on how to change the IR channel on the 4x1 HD Switcher w/ Audio Decoding.

  • Page 29: Saving Audio Processing Favorites

    MENU SYSTEM Saving Audio Processing Favorites The 4x1 Switcher w/ Audio Decoding, allows any of five audio processing modes to be associated with a selected input. For example, you may want to associate the Multichannel Stereo audio processing mode with the optical (TOSLINK) input. On the other hand, you may want to set the Dolby Pro Logic II (PLII) audio processing mode when using the analog L/R inputs, in order to create discrete multichannel audio when using a surround system. These two examples will be illustrated. Available Modes Mode Description Audio playback without any processing (default setting). The input signal is the same as the output signal. DIRECT Multichannel audio is down-mixed to two-channel audio and routed to the Front Left / Front Right speakers. STEREO Mixes the SL and FL channels to the Front Left Speaker; Mixes the SR and FR channels to the Front Right Speaker. If the Center channel is present, then the Front Left, Front Right, and Center channel will be used to produce a stereo MCH STER image. If the Center channel is not present, then only the Front Left and Front Right speakers will produce the stereo image. If the Center channel speaker is present (or enabled), the audio is played only through the Center channel (the Front Left and Front Right speakers will be muted). If the Center channel speaker is not present (or disabled), Front Left MONO and Front Right signals will be combined and played out of the Front Left and Front Right speaker. Transforms two-channel stereo into high-quality 5.1-channel surround sound.
