4.0 CONNECTING THE HARDWARE
Please study the panel drawings below and become familiar with the signal input,
outputs, power requirements/inputs plus any controls present.
The front panel contains the power switch and LED Power Indicator, the Infrared Sensor
window and the four input selectors with LED indicators that show which input has been
selected.
From left to right, the rear panel features the RS-232 connector, the output connectors
for S-Video, Composite Video, RCA type connectors for Left and Right audio channels
and a 3.5mm Mini plug for the same audio signals.
To the right of the output connectors are four identical sets of input connectors for
channels 3 and 4 and, farther to the right, for channels 1 and 2. The connectors are for
analog stereo audio (R&L channels), Composite Video and S-Video. Finally, at the
extreme right is the power connector used to connect the AC power adapter.

The user should connect the inputs using high quality cables, connect the RS-232 cable
if used and finally connect the video and appropriate audio outputs to a monitor or
projector or other destination device. After connecting the signal cables, the AC power
adapter should be connected, first to the MX-3141CSVA and then to the AC power
source.
5.0 OPERATING THE MX-3141CSVA
Once the signal cables and AC power adapter have been connected, the switcher can
be turned on using the front panel power switch. If the appropriate signals have been
applied to the inputs, a high quality signal should appear on the monitor or projector as
each input is selected. Gain is unity so the output should mirror the inputs in all cases.
Note: Audio I/O is line level. It is not possible to directly feed speakers or receive audio
from a source speaker output. Damage may result if attempted.
5.1 OPERATING THE MX-3141CSVA USING THE INCLUDED IR REMOTE
Operation of the switcher via the included Infrared Remote Control is a matter of simply
pointing the remote at the MX-3141CSVA and selecting the appropriate input on the
remote control. In order for the remote to function properly, the small square window on
the front of the MX-3141CSVA must be unobstructed and not in sunlight or extremely
bright artificial light. The distance from the IR remote and the switcher should not be
more than in a standard residential room.
6.0 TROUBLESHOOTING
Most problems encountered with the MX-3141 series of products relates to faulty
cables, incorrect signal levels from the sources or an attempt to connect more than one
source to an individual channel.
If some inputs function correctly and others do not, interchange cables between sources
and see if the problem moves with the cables. If it moves, a bad cable or cable
connector is the probable reason for the trouble. If the problem remains with one
particular input, connect that source to a different input using the same cable and see if
the problem moves. If it does, the problem is with the source.
As to multiple connections made to the same input, it is not possible to have both an S-
Video source and a Composite Video source on the same input. Connect only one or
the other to an individual input.
After trying the above suggestions should the problem still persist, contact your dealer
for additional suggestions before contacting TV One. Should the dealer’s technical
personnel be unable to assist you, contact TV One via our support website:
http://tvone.crmdesk.com. Create a technical support request on the site and our
support team will respond within a short period of time.
