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. ■ Video
● Max. resolution: QWXGA (RB)*1, 1080p ● Digital cable compensation circuit Input and Output: Max.10 m/32.8 feet to 50 m/164.04 feet ● Anti-snow*2
■ Audio
● Analog audio conversion output
■ Others ● EDID emulation (with copy) ● DDC buffering ● HDCP ● Displaying statues of Input/Output signals ● Connection reset*3
*1 Only 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.

The problem can be solved by using the CEC physical address that is copied into the VAC. Setting values
on: Copy physical address oFF: Not copy physical address [Default]
Notes: ● This is enabled if CEC-supported source and sink devices are connected and one of 03 to 22 is selected
for resolution setting of EDID. ● CEC system link functions supported by other companies are not guaranteed to work correctly by this
setting. Check the actual configuration.
7.2.16 [F40] Setting input equalizer
If it is set to “00” (AUTO), automatic equalization is normally performed depending on the amount of input signal attenuation. However, it may not be performed automatically in some PCs. In these cases, set the amount of equalization manually according to the cable length.
Setting values 00: AUTO [Default] 01 to 25: Low to high
Notes: ● If you use a 5 m/16.4 feet or longer cable for input, we recommend that you check the configuration with
actual devices in advance, because it largely depends on the output signal quality of the source device. ● Set the equalizer value before using the VAC, since images sometimes are interrupted when the setting is
changed.

made by IDK (AWG24) is used and signals, 1080p 60 Hz 24bit/pixel (8bit/component), are input or output. If the connected device is
not matched to the VAC or if other makers' cables are used, video signals can be unstable or video signals cannot be output, even
though the transmission distance is within the information above.
*4 Anti-snow function automatically eliminates snowy noise that is a specific symptom of the signal having HDCP. This feature
automatically eliminates the snow noise causing mainly at start-up of the device. If the noise occurs in the input signals or if the noise is
caused by bad-quality signal transmission, this feature does not work.

9 Troubleshooting
In case this device does not work correctly, please check the following items first. • Are this device and the connected devices turned on normally? • Are cables connected correctly? • Are there no loose connections? • Are cables that are appropriate to this device being used? • Are signal specifications of connected devices matched to each other? • Are settings of the sink device correct? • Are there any close objects that may cause noise?
If the problem still cannot be solved, check the items in the table below. Please refer to manuals of connected devices as well, since they may possibly cause the problem.
Problem Check item Video output Video is not output. If there are no problems with cable connections, first check [1] and [2] below. [1] Verify that the EDID resolution setting of the VAC is set to the
input resolution supported by the display device. ・The EDID resolution is set to 1080p by default, but some TVs do
not support that resolution. ・If the EDID resolution is set to 1080i, the video may not be output to
the display device that does not support the interlaced signals. ・Some monitors for PCs do not support the resolutions for TVs. Some
LCD TVs do not support PC resolutions (VGA to QWXGA). [2] Verify that signals are output from the input device.
If the “SIGNAL” LED lights, check [3] to [6]; if the LED turns off, check and [8].
[3] If signals protected by HDCP are input, does the sink device support the HDCP? If the sink device does not support HDCP, copyright-protected signals are not displayed. Check whether the sink device supports the HDCP. You can also disable HDCP output to the source device by an input setting.
[4] If a long cable is connected for input or output, replace it with a 5 meter/16.4 feet or shorter cable. A 5 meter/16.4 feet or longer cable can be connected for digital input/output for the VAC, but some cables fail HDCP authorization or EDID acquisition depending on the quality of the cable and connected devices.
[5] Verify that unsupported signals are not being input. [6] Change the [C10] setting. Access this menu by changing [F99]
setting. [7] Verify that No-signal input monitoring time ([F16]) is not too short. [8] Check the video output setting of the source device.

Problem Check item Interference or noise appears on video.
If a long cable is connected for input or output, change the equalizer setting. If a long cable is connected for input or output, replace it with a 5 m/16.4 feet or shorter cable. Even though a 5 m/16.4 feet cable can be connected since the VAC has compensation circuit for digital input and output, it cannot deliver its full performance depending on the cable quality and connected devices. If the problem is solved by the replacement with a shorter cable, the signals may have been deteriorated because of the long-distance transmission. IDK provides high-quality cables, boosters, and cable extenders. Please contact us as needed.
Transmission clock of Deep Color signals is faster than normal signals. If poor-quality or long cable is connected at the time of signal input or output, noise may appear on the video. The color depth of input signals can be controlled in the EDID setting.
Video blinks. If interlace signals are input to a sink device that does not support interlace signals, the video blinks. Check the supported resolution of the sink device.
Video edges (up/down/right/left) are cut out.
Some sink devices display input video in overscan, and the video may be cut out. Check the display setting of the sink device.
Video is distorted horizontally or vertically.
Some sink devices display input video on full screen, and the aspect ratio cannot be kept. Check the display setting of the sink device. With some resolutions, full-screen display cannot be avoided. In that case, change the output resolution of the source device.
Black bars appear on PC images. Only part of the PC image is displayed, and the rest of the images is displayed by moving the mouse.
If the PC has the Panel Fit function, select “Scale Full Screen”. If the resolution that is set for the PC and the resolution that is actually output from the PC are not matched, those problems may occur. Check the resolution of the PC and the EDID resolution setting.
The dual monitor function cannot be set or it is canceled automatically.
When the No-signal input monitoring function works, the dual monitor function may not be enabled correctly. In this case, turn off this monitoring function.

Problem Check item Video is displayed, but audio is not output.
Verify that audio output is turned on. If there are multiple output connectors in the source device, check the audio output setting of the source device.
Verify that audio whose format is supported by the connected sink device is input. Especially, LCD monitors may not output 88.2 kHz or higher linear PCM and compressed audio (such as Dolby Digital and DTS). In order to play a Blu-ray disc having compressed audio, check the audio output setting of the source device. You can also control audio signals that will be output from the source device by setting EDID.
Verify that DVI signals are not being output from the source device. Even though multi-channel audio is played, only audio signals of 2 channels are output.
For multiple channel play, change the EDID setting which is set to 2 channels by default.
Audio is output from HDMI output, but it is not output from analog audio output.
If compressed audio (such as Dolby Digital and DTS) is input, analog audio is not output. Only 2-channel linear PCM is supported for analog audio output.
Audio is output from analog audio output, but it is not output from HDMI output.
Verify that audio output is set to ON. Verify that audio can be output by the connected sink device with the selected resolution. If an output resolution for PCs (VGA to QWXGA) is selected, the sink device may not output audio.
Verify that the selected sampling frequency is supported by the connected sink device. Some LCD monitors cannot output high-sampling frequency audio (88.2kHz or higher). Audio signals output from the source device can be controlled by setting EDID.
Compressed audio (such as Dolby Digital and DTS) is not output from the source device.
Inputting compressed audio is limited by the EDID setting(factory default). In order to use compressed audio, change the EDID setting.
Check the audio output setting of the source device. Devices cannot be controlled by CEC.
If you use CEC, enable the HDMI link control function of devices to be connected to the VAC, such as LCD TVs and Blu-ray disk recorders.

10 Fuse
The VAC is equipped with a glass tube-type fuse (5 × 20 mm/0.2 x 0.79”), which prevents overcurrent from flowing into the VAC when a circuit or circuit part is broken. If the VAC cannot be turned on, first check if the fuse placed in the AC inlet is blown or not. If it is blown, replace the blown fuse with the spare fuse by following the procedure below.
1. Turn off the VAC and unplug the power supply plug. 2. Remove the power connector from the AC inlet 3. Remove the fuse holder by pulling out the depressed portion of the connection area for power
supply connector using a screw driver or the like.
