The Boxed Intel® Desktop Board D845PEBT2 is configured with three complete audio output solutions. The first audio output is analog, by means of three 1/8-inch stereo jacks. The other two are digital outputs using Sony* and Philips* Digital Interface, as known as S/PDIF. The first S/PDIF output uses an RCA connector, and the second S/PDIF output uses a Toslink connector. Toslink is an optical port for communicating between audio components via fiber optics.
Front Panel Analog Audio
Front panel analog audio connector that can be used as a connector for routing the following signals to the front panel or used as a jumper block for routing the signals to the back panel
The connector/jumper block includes pins for:
- Front left and right output
- Microphone in
ATAPI Style 1x4 pin header for CD-ROM audio
A 1 x 4-pin connector connects an internal ATAPI CD-ROM drive to the audio mixer.
Back Panel Analog Audio Connectors (2 speakers)
Located on the back panel I/O the front channel left and right analog outputs is the 1/8-inch light-green connector. This is part of the triple stack audio connectors located on the back panel I/O. The light-green connector is used for stereo left and right channels. But is also used as the front left and right channels of a 4 or 6 channel audio configuration.
Note: Powered speakers are required.
Back Panel Analog Audio Connectors (4 or 6 channel configurations)
The light-green connector of the triple stack audio ports is front left and right audio analog output. For implementing a 4- or 6-channel analog audio configuration, the light-green port becomes front left and front right channels. The port uses a 1/8-inch stereo jack. The tip is front left, the ring is front right, and the sleeve is ground.
Note: Powered speakers are required.
4-Channel Configuration:
The double stack audio port provides rear channels, low frequency effects, and center channel analog audio outputs. The top connector is the rear left and rear right. The port uses a 1/8-inch stereo jack. The tip is rear left, the ring is rear right, and the sleeve is ground.
Note: Powered speakers are required.
6-Channel Configuration:
The double stack audio port provides rear channels, low frequency effects, and center channel analog audio outputs. The top connector is the rear left and rear right. The port uses a 1/8-inch stereo jack. The tip is rear left, the ring is rear right, and the sleeve is ground. The bottom connector is the Low-Frequency Effects (LFE) and center analog audio outputs. LFE, or Low-Frequency Effects is what would be connected to a powered sub-woofer. The tip is center, the ring is LFE, and the sleeve is ground.
Note: Powered speakers are required.
Back Panel Digital Audio Connectors
The Intel® Desktop Board D845PEBT2 features two digital outputs using Sony* and Philips* Digital Interface, as known as S/PDIF. The first S/PDIF output uses RCA, and the second S/PDIF output uses Toslink. Toslink is an optical port for communicating between audio components via fiber optics.
Digital audio output is only compatible with audio peripheral that support 6-channel audio inputs, such as commercial sound equipment. Confirm with your commercial sound equipment manufacture to determine if the equipment supports either RCA or Toslink 6-channel digital input. The digital output contains no amplification. Your commercial sound equipment must provide the amplification for the speakers.
