Thanks for purchasing this 1311 or 1312 AV signal converter from
Audio Authority. The 1312 converts HDMI inputs to Digital DVI
signals and provides an S/PDIF Audio output. The converted HDMI
video signal can then be connected to an HDTV with a DVI input
or to a DVI switcher’s inputs. The 1311 converts a Digital DVI
signal and S/PDIF Audio input to an HDMI format allowing the
viewing or switching of a digital AV signal on an HDMI system.
Both the 1311 and 1312 are HDCP compliant. Audio Authority
also offers an extensive line of audio and video switchers,
converters and distribution amps available for purchase online at

User Manual
Before attempting to use this unit, please check the packaging and
make certain the following items are contained in the shipping
• 1311 or 1312 Audio Video Converter
• 5 VDC AC Power Adapter
• User Manual
Note: Please retain the original packing material should the need
ever arise to return the unit. If you find any items are missing,
contact Audio Authority immediately. Have the Model Number,
Serial Number and Invoice available for reference when you call.
Please study the panel drawings below and become familiar with the
signal input(s), output(s) and power requirements.
Model 1311 DVI + Digital Audio to HDMI Converter
Model 1312 HDMI to DVI + Digital Audio Converter
Before installation, please make sure all devices you wish to connect
have been turned off.
• Connect the AC adapter to the Converter’s power input (Do not
plug the adapter into an AC outlet yet).
• Connect the appropriate cables to the source device and then the
• Connect the output cables to the Converter and then to the
destination device.
• Plug the Power Adapter into a working AC outlet.
• Power on all input and output devices.
• The DVI-HDCP input signal should now be available to all devices
connected to the device outputs. Neither converter unit has any
controls that require adjustment.
If the Converter does not appear to be functioning, make certain
that the source and destination device connected to the unit are
functioning correctly by connecting each device using a cable with
a length of 6 feet or less. (In other words, make certain that the
problem is not caused by long cables.) If the signal is present under
those conditions, make certain that the power is present to the
converter. If it is, measure the cable length you are attempting to
use between the sources to the switcher and the switcher to the
monitor. The input cables should be 6 feet or less in length and the
output cables must be less than 33 feet long and all cables should
be premium quality. Lastly, inspect the cables and connectors for
6.1 Non-HDCP Compliant Devices
If a DVI device does not appear to work, make certain that the device
is HDCP compliant. A non-HDCP compliant DVI device will not work
with a signal that has HDCP encoding present.
6.2 Cable Length
If you need to span a distance of greater than 6 feet to reach the
converter, purchase Audio Authority’s 1351 DVI Repeater which will
allow you to extend a cable run up to 40 feet using premium cable.
6.3 Complex Configurations
Due to the nature of High-bandwidth Digital Content Protection,
and the many types of information that must be passed along
the chain of devices, complex configurations involving DVI
distribution amps and switchers may not work as expected. Do not
use a DVI switcher in the signal path after a distribution amp; this
configuration does not work.
If the problem still persists after trying the above suggestions,
contact the Audio Authority Technical Service department via email:
[email protected], or call 800-322-8346 or 859-233-4599.
