2 Product outline
The VAC-5000HD is an HDMI distribution amplifier for distributing digital video and audio signals to 5 outputs.
Since signals can be distributed to multiple devices that have the HDMI input connector, the VAC can be used
for multiple systems of HD images, production lines, and others. An L/R stereo audio output is provided, and
only the embedded digital audio input is converted into an analog stereo signal for the stereo analog audio
outputs. The HDMI input has an automatic compensation circuit while the HDMI output has a manual one,
and they are able to minimize signal degradation caused by cable extension.

3 Features
Video and audio signals input from the source device can be distributed to multiple sink devices. Audio can be
output as digital or analog signals.

*1Only Reduced Blanking is supported.
*2 The anti-snow feature automatically fixes snow noise that is a specific symptom of HDCP-compliant
signals and mainly occurs at start-up. This feature does not work when snow noise has already occurred
during startup or when it occurs due to a bad condition of the transmission line.
*3 For digital systems, some problems, such as an HDCP authentication error, can often be recovered by
physically disconnecting and reconnecting the digital cables. However, the Connection Reset feature will fix
these problems automatically without the need to physically remove and insert the cables. It creates the
same condition as if the cable were physically disconnected and reconnected. This feature only works for
the VAC’s output. If other devices are connected between the VAC’s output and display device, this feature
may be invalid.

5.2 Precautions before connection
Follow the precautions below before connecting to external devices.
■Installation
●Do not block vent holes. Keep enough space (3 cm/1.18 inches or more) around the product.
●Do not install the VAC in a closed space.
If you have to install the product to an EIA rack mount in closed space, add a ventilation to keep the
ambient temperature of 40 degrees C/104 degrees F or less. If inadequately vented, the life of parts
may be shortened and operations may be affected.
■Cabling
●Read the manuals of external devices carefully.
●Turn off the transmitter/receiver before connection.
●Insert the cable into the connector firmly and do not give the connector stress.
●Secure the HDMI cable using a cable clamp to prevent it from falling out of the device.
[Fig. 5.4] Attaching cable clamp
HDMI cables and connectors do not have a lock mechanism. Use the supplied cable clamp to apply the HDMI
cable to the VAC.
