3.0 CHECKING PACKAGE CONTENTS
Before attempting to use this unit, please check the packaging and
make certain the following items are contained in the shipping
carton:
• HDMI Distribution Amplifier
• 5 VDC Power Adapter
• IR Remote Control
• Remote Mounting Kit
• User Manual
Note: Please keep the original packing material in case the unit
ever needs to be returned. 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.
4.0 CONNECTING THE HARDWARE
For reference purposes, only the 1372 is depicted below. The 1374
is larger and has two more inputs. Please study the drawings below
and become familiar with the location of the controls, status LEDs,
signal inputs, signal output and the power input.
• Connect an HDMI approved cable, no more than 50 feet in length,
from each of the HDMI sources to the inputs of the switcher.
• Connect the output of the switcher to the destination device using
an HDMI approved cable no more than 50 feet long*.
• Connect the extended IR remote cable if desired.
• Connect the power adapter, first to the switcher and then to the
AC outlet.

* Proper operation of HDMI switchers depends on the use of premium
quality HDMI cables that provide low loss, high bandwidth signal
handling. The distance specification of 50 feet is for HDMI signals
up to 1080i; this specification cannot be guaranteed unless cables
meeting these standards are used throughout the system.
4.1 Installation of Mounting Components
The switchers can be mounted on any flat surface. Attach the two
“L” shaped mounting brackets to the product using the furnished
hardware and then attach the combined assembly to the desired
location. Note that the holes on the brackets are offset to allow
easier mounting to the flat surface after you’ve attached the
brackets to the switcher.

5.0 OPERATING THE UNIT
Power and input selection are controlled from one multi-purpose
switch. To turn the switcher on, press the Input Select – Power
On/Off switch. Once the unit is in the operating state, pressing the
switch causes the input selection to advance each time it is pressed.
(An LED lights to show which input is active.) Once the highest
input number is reached, pressing the switch again will select input
number 1. Pressing and holding the switch for two (2) seconds will
cause the unit to power off.
For greater flexibility, an Infrared remote control is also provided.
In the case of the remote, there are separate buttons for the power
and input sources. Point the remote control at the unit and press the
power button to turn the switcher on or off. Press the appropriate
input select button to cause the desired input to appear on the
switcher’s output.
6.0 TROUBLESHOOTING
• First make certain that the input cable is no more than 50 feet
long and none of the output cables is more than 50 feet long (for
signals up to 1080i) and are of the highest possible quality.
• Make certain that the switcher is receiving power by looking at
the power LED.
• If you still experience problems using the switcher, you should
attempt to determine what is wrong by first attaching the source
devices directly to the destination device in turn using the same
cables you are using with the switched system. This is a way of
determining if the problem is due to bad cables or a problem
with the other devices. If you are unable to obtain a signal using
this simplified path, suspect the cables, a source device or the
destination device.
• Remember that HDMI devices communicate with one another
so the source device and all destination devices must be fully
HDMI capable. In addition, HDCP encryption requires processing
dependent on the equipment you have connected to both the
source and destination devices.
If the problem still persists after trying the above suggestions,
contact the Audio Authority Technical Service department via email:
support@audioauthority.com, or call 800-322-8346 or 859-233-4599.
