Installation Manual
Note: The KXI-DVI-Bridge’s input can be static content (such as computer-generated text and static graphics)
to be scaled and merged against the layout background on the Kaleido. In this case the dongle is generally not
required. For the KXI-DVI-Bridge to process dynamic content (such as streaming video or computer-generated
animations), the dongle is required. Please refer to your KXI-DVI-Bridge User’s Manual for more information.
2.4.6 Analog Audio Inputs (Optional Alto-SA Mezzanine with 10 or 4 Inputs)
This option provides inputs for 10 or 4 channels of analog stereo audio. Two DB-44S connectors are available
on the Alto-SA mezzanine.
Connect balanced analog stereo audio signals to the audio input connectors. Each connector receives 5 stereo
inputs (refer to figure 2.4.4 below for connector pinout). For the 4-input audio version only inputs IN 1-4 are
available.
To facilitate cabling of the audio inputs, a terminal block adapter is available separately (Alto-TBA-AG). A Lexan
plate is provided to identify the terminal assignment for the input connectors. See figure 2.4.6 for plate
installation on the Alto-TBA-AG terminal block adapter.

2.4.7 Digital Audio Input (Optional Alto-AES Mezzanine)
This option provides inputs for 10 or 4 channels of AES/EBU digital audio. A single DB-44S connector is
available on the Alto-AES mezzanine.
Connect AES balanced audio signals to the audio input connector. Signal must conform to AES3-1992/ANSI
S4.40-1992 standard. The DB-44 connector receives 10 inputs (refer to figure 2.4.5 below for connector
pinout). For the 4-input audio version only inputs IN 1-4 are available.
To facilitate cabling of the audio inputs, a terminal block adapter is available separately (Alto-TBA-AG). A Lexan
plate is provided to identify the terminals assignment for the input connectors. See figure 2.4.6 for Lexan plate
installation on the Alto-TBA-AG terminal block adapter.
