General Information
The Model 1154B High Definition AutoSelectorTM complements a wide array of home theater signal sources, video displays, and audio systems. It performs selection of up to four input sources by infrared control, by a unique AutoSelectTM process, or by manual selection. A/V inputs may be component video and digital or analog audio, or combinations of these signal types, all delivered to the viewer with their original vividness, brightness, and clarity. LED indicators on the front panel show active source inputs in green, and the source that is currently selected in red (see page 6).
When active, AutoSelect detects a new source signal by listening for changes in the audio signals, and automatically switches to that input. It uses multiple criteria for switching decisions, including newly detected signals, the presence of digital and/or analog audio, and priority according to position; position 1 has highest priority.)

Installation
1. Model 1154B Hookup. Connect sources, receiver, and monitor in these steps.
a. If the AutoSelect feature is to be used, decide now if any devices should be connected directly to the TV or receiver, particularly if the sources include a device that can record. Also consider the priority arrangement of the sources (see About AutoSelect on page 5).
b. Connect each source unit to its respective set of Model 1154B input jacks.
c. Use good quality cable and keep the runs under 6 feet if possible, especially for component video connections.
! d. Connect either optical or coaxial, but NOT BOTH types of digital audio inputs. Connect all the other signals available from the source unit: component video and analog audio.
NOTE! Certain audio input signals may be used by the Model 1154B for AutoSelect, even though they are not required by the video display or audio system. Connect every cable (but only one type of digital audio) to assure proper AutoSelect functionality.
e. Connect the HDTV video display and audio system to the Output jacks. Use either optical or coaxial digital audio outputs, but NOT BOTH. Use the analog audio output only if the audio system lacks a digital audio input, or if TV sound is desired.

2. Initial Testing. Connect the furnished 12 volt power supply, then perform the following steps:
a. Check that one or more panel indicator lights are illuminated.
b. Apply power to all associated equipment. Touch the input selection keys 1-4 to manually select sources to verify video and audio signal integrity.
3. Remote Control. The Model 1154B can select sources by infrared remote (Model 581-023). Press keys 1-4 to directly select an input, or use the Up or Down arrow keys to scan the inputs, including Auto. If you are using other Audio Authority switchers having the same "credit card" remote control, or if the 1154B remote interferes with the IR control of any other product, press and hold one of the ABCD keys for 2 seconds to change codes. The 1154B will blink its indicator lights a few times to verify that it received and understood the IR code change.
About AutoSelectTM
Establishing Switching Priority AutoSelect uses the presence of audio signals as switching criteria, but another criteria is a source's numerical priority. This feature is useful for sources that constantly produce audio signals even when switched off, such as a satellite box that produces a blank digital audio bitstream when powered down. Any digital signal is "audio" to the 1154B, therefore it may consider the source producing the blank bitstream as active and select it for play. Choosing the connection order of your sources is the best way to optimize AutoSelect decision process and prevent incorrect selection caused by such sources.
Generally, sources that retain digital audio output even when turned off should be connected to the higher numbered inputs (positions 3 and 4). The example lists of sources below are correctly prioritized from lowest to highest input number. These lists represent typical situations, one without (Example A) and one with (Example B) a PVR or automatic recording device.
Priority/Source
Comment
Example A:
1 DVD player 2 Game box 3 Cable box 4 Satellite receiver
Usually does not produce null output Usually does not produce null output Usually does not produce null output Sat receiver may produce null output
Example B:
1 DVD player 2 Cable box 3 Satellite receiver 4 PVR
Usually does not produce null output Usually does not produce null output May produce null output Produces null output
AutoSelect and Recording Devices AutoSelect is ideal if most components will not be powered at one time, because the 1154B looks for newly appearing inputs as one of its decision criteria; however, another factor must also be considered. Any source that records, such as a personal video recorder or PVR, should be constantly powered up so it can record even when not playing. When a PVR begins to record, the 1154B may mistakenly select that input, interrupting the device you actually intended to watch. If this happens in your system, the reliable way to avoid this problem is to connect the outputs of a PVR directly to a home theater receiver or TV instead of the 1154B. The PVR can then be chosen with the TV or receiver's remote control when desired.
High output noise level or other signal deficiencies from a source may cause the Model 1154B AutoSelect logic to fail. If this happens frequently, the best solution is to deactivate AutoSelect and use the IR Remote Control included with the 1154B.

Operation
The Model 1154B allows you to select one of up to four video/audio sources to play through your home theater system. Each of the four input keys lights green if an input is detected, and red if the input is selected (see below). Generally, the most recent input to be detected is the one that the 1154B AutoSelects.
RED = AutoSelect ON
GREEN = Signal detected
RED = Currently selected input

To enable the AutoSelectTM feature to automatically switch to a newly powered source, touch the Auto key. The 1154B detects digital and/or analog audio signals; it does not detect video signals if an audio signal cannot be detected by the 1154B. The 1154B listens for the presence of digital audio and analog audio and switches to the input position that has the newest signal.
For manual selection, simply touch the key of the source you want to watch. When making a manual selection, AutoSelect is disabled and you must touch the Auto key to reactivate it.
Pressing Keys 1-4 of the Infrared Remote Control immediately selects the respectively numbered input. Scan through the four inputs and Auto Mode sequentially by pressing the Up or Down arrow keys.
Troubleshooting
If at any time the 1154B fails to respond as expected, use the outline below to find the cause or narrow the possibilities. If your question is not answered in this guide, call Audio Authority Technical Support at 800-322-8346.
