1 - Important safety instructions
Warning: When using electrical products, basic cautions should always be followed,
including the following:
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any of the ventilation openings. Install in accordance with manufacturer’s
instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves or other
apparatus (including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug
has two blades with one wider than the other. A grounding type plug has two blades and a
third grounding plug. The wide blade or third prong is provided for your safety. If the
provided plug does not fit into your outlet, consult an electrician for replacement of the
obsolete outlet.
10. Protect the power cord from being walked on or pinched, particularly at plugs,
convenience receptacles, and the point they exit from the apparatus.
11. Only use attachments/accessories provided by the manufacturer.
12. Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold
with the apparatus. When a cart is used, use caution when moving the cart/apparatus
combination to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus
has been damaged in any way, such as power-supply cord or plug is damaged, liquid has
been spilled or objects have fallen into the apparatus, the apparatus has been exposed to
rain or moisture, does not operate normally, or has been dropped.
15. Never break off the ground pin. Write for our free booklet Shock Hazard and Grounding.
Connect only to a power supply of the type marked on the unit adjacent to the power
supply cord.
16. If this product is to be mounted in an equipment rack, rear support should be provided.
17. Note for UK only: If the colors of the wires in the mains lead of this unit do not
correspond with the terminals in your plug‚ proceed as follows:
a) The wire that is colored green and yellow must be connected to the terminal that is
marked by the letter E‚ the earth symbol‚

d) The wire that is colored brown must be connected to the terminal that is marked with
the letter L or the color red.
18. This electrical apparatus should not be exposed to dripping or splashing and care should be
taken not to place objects containing liquids, such as vases, upon the apparatus.
19. The on/off switch in this unit does not break both sides of the primary mains. Hazardous
energy can be present inside the chassis when the on/off switch is in the off position. The
mains plug or appliance coupler is used as the disconnect device, the disconnect device
shall remain readily operable.
20. Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals
vary considerably in susceptibility to noise-induced hearing loss, but nearly everyone will
lose some hearing if exposed to sufficiently intense noise for a sufficient time. The U.S.
Government’s Occupational Safety and Health Administration (OSHA) has specified the
following permissible noise level exposures:
According to OSHA, any exposure in excess of the above permissible limits could result in
some hearing loss. Ear plugs or protectors to the ear canals or over the ears must be worn when
operating this amplification system in order to prevent a permanent hearing loss, if exposure is
in excess of the limits as set forth above. To ensure against potentially dangerous exposure to
high sound pressure levels, it is recommended that all persons exposed to equipment capable
of producing high sound pressure levels such as this amplification system be protected by
hearing protectors while this unit is in operation.

February 6, 2014 Version 1.7.0a.1 11
Updating the firmware
Problem
What to do
No output image
Check if there is any signal at the input.
Check if there is any signal at the output.
You can check these using an oscilloscope or a multimeter.
Ghosting on image
This is generally is not a faulty switch/scaler, but may be
caused by poor quality cabling (to or from the switch/scaler), or
incorrect setup on the display. Check cables and their
connections, as well as the display setup.
4 - Maintaining the unit
You can update the firmware on the VSC-51 using a flash disk inserted into the USB port at
the front. MediaMatrix Technical Support (mailto:mmtechsupport@peavey.com) will provide
you with the files you need to install on the flash drive and explain the procedure.
To update the firmware
1. Copy the new firmware file to the main (root) directory of a USB flash disk.
2. Connect the VSC-51 to a video monitor via the HDMI output.
3. Plug the USB flash disk into the VSC-51 USB port.
4. Press and hold the MENU button for 15 seconds or until the update menu appears on the
video monitor.
The VSC-51 will automatically find and install the new firmware from USB flash disk.
5. After the update is finished, reboot and send the command 0617% to the RS-232 serial port
to restore the unit to factory settings.
6. Reboot once again to finish the process.
Tip: If sending the RS-232 command to restore factory settings is unsuccessful, change
the output baud rate to 115200 and try again. Remember to return the unit to the normal
serial communication settings: RS-232, baud rate: 9600, data bit: 8, stop bit: 1, parity:
none.
Troubleshooting
12 Version 1.7.0a.1 February 6, 2014
Problem
What to do
Waves on image
If the output image has waves, especially if the waves move up
or down, check that all devices and components (video players,
computers, etc.) are grounded properly.
Static or waves become
stronger when connecting
using RCA connectors
Possibly due to incorrect grounding. Check grounding
immediately. This could cause damage to the VSC device.
Remote control not working
Check that the batteries are inserted correctly. Check that the
batteries are charged. Replace batteries as necessary.
RS-232 control not working
Check that the baud rate on the VSC device matches the baud
rate set on the connected device.
When a computer is being used, check that the COM port set on
the computer matches the COM port set in the OSD on the VSC
device.
Make sure the serial port is in good working condition.
Try swapping the TX and RX at one one.
Power LED unlit
Make sure the power cord connection is good, and that the
adapter (if used) is working. Make sure that there is power at
the outlet.
Device does not respond
when buttons are pressed on
the front, when the remote
control is used or when
RS-232 communications are
active.
The VSC device may need repair. Contact your dealer.
VSC-51 supports many types of video signals, including C-Video, S-Video, YPbPr, VGA and
HDMI. All inputs are scaled to the selected HDMI format output.
C-Video and S-Video input
Supports PAL, SECAM and NTSC formats.
From the OSD, the aspect ratio can be set to full-screen, wide screen or 4:3.
