2.4 VIDEO CONNECTIONS
Connect up to sixteen baseband video SOURCES (cameras, VCRs, DVD
players, satellite receivers, RF demodulators, etc) to the NTSC, Y/C, or HDTV
video input connectors. Inputs are automatically terminated in 75 ohms. It is not
necessary to terminate unused inputs.
Connect up to sixteen ZONE destination devices (TV monitors, VCRs, LCD
projectors, RF modulators, etc) to the NTSC, Y/C, or HDTV video output connec-
tors. Be sure that all destination devices are terminated in 75 ohms. It is not
necessary to terminate unused outputs.
Do not connect a SOURCE of video to any of the video OUTPUT connec-
tors.
2.5 AUDIO CONNECTIONS
Connect up to sixteen balanced or unbalanced audio SOURCES (CD players,
tape players, VCRs, microphones, RF demodulators, etc) to the left and right
channel input connectors. For balanced audio units, the common is at the center
and the + and - are as shown on the panel. Inputs are high impedance (15K). Note:
an unbalanced source may be connected to a balanced input by connecting the
signal lead of the audio source to the + input and connecting the shield to both
the center and - inputs.
Connect up to sixteen audio destination ZONE devices (amplifiers, VCRs,
tape/CD recorders, RF modulators, etc) to the left and right channel output con-
nectors. Devices may be terminated with a 1Kohm load.
Do not connect a SOURCE of audio to any of the audio OUTPUT connec-
tors.
