INTRODUCTION  
AS2 and AS2/S NEW FEATURES  
Thank you for purchasing the AS2 — AS2/S Automatic Speaker Source  
Selector. The AS2 and AS2/S automatically switch a single pair of speakers  
between two speaker-level stereo sources: a main source connected to the Input  
A terminals and a remote source connected to the Input B terminals.  
The AS2 and AS2/S incorporate several new features that improve their  
performance and installability:  
• The AS2 operates on a single-output 12V DC power supply, and can also be pow-  
ered directly by 12V sources in cars, boats or RV installations. The AS2 power inputs  
have reverse polarity protection.  
When the AS2 senses a remote source signal present at the Input B terminals,  
that source signal is automatically switched-through to the output terminals.  
When the remote source signal is no longer present on Input B, after a short  
(installer-adjustable) time delay the AS2 and AS2/S automatically switch the  
outputs to the main source connected to the Input A terminals.  
• The AS2 features DC In and DC Out connections that allow multiple Industry  
Upgrade units to share a single power supply.  
• The AS2 and AS2/S Input, Output and Control connectors are removable quick-  
toggle RIA connectors.  
• The AS2 and AS2/S chassis have recessed mounting holes that allow them to  
easily be wall-mounted using two screws.  
• The AS2 and AS2/S chassis’ are compatible with 3” TK-series SnapTrack® from  
Augat.  
The time it takes the AS2 and AS2/S to switch back to Input A from Input B  
can be adjusted to suit the different types of audio sources being used, or the  
preferences of the listeners. The sensitivity of the detection/switching circuitry  
is also adjustable to work with a variety of audio source equipment.  
APPLICATIONS  
Here are three examples of how the AS2 and AS2/S can be used in different system configurations:  
Switching Between Speaker-Level Sources (see Illustration 1)  
As a Paging System “Break-In” Device (see Illustration 2)  
The AS2 can automatically switch two speaker-level sources, such as a whole-  
home audio system and a local TV set, to a single pair of speakers.  
The AS2 can serve as a “Break-In” device for paging applications. The  
continuous music source would be connected to the AS2’s Input A, the  
paging system amplifier would connect to the AS2’S Input B, and the AS2’s  
Outputs would connect to the local speakers. When the paging amplifier is  
activated the AS2 would switch to Input B to reproduce the page; after the page  
had ended it would revert back to the music signal connected to Input A.  
With the whole-home system amplifier connected to the AS2’s Input A and the  
local zone TV’s speaker outputs connected to the AS2’s Input B, the whole-  
home system would be the speakers’ main source and would remain auto-  
matically selected by the AS2 whenever the TV was turned OFF. When the TV  
is ON it sends an audio signal to the AS2, which would then automatically  
select the TV as the active source and send its signal to the speakers.

Using the AS2 Control Output with Multiple Slave Units  
OTHER SONANCE INDUSTRY UPGRADE COMPONENTS  
The AS2’s Control Output can supply up to 200mA of current. This allows it  
to be daisy-chained with up to two (2) AS2/S slave units (or up to five (5)  
AL2/S slave units).  
AVL1 Automatic Audio/Video Source Selector  
The AVL1 provides automatic stereo line-level audio and composite video  
switching between two audio/video sources (such as a VCR, cable TV tuner or  
DVD player). Features and operation are otherwise identical to the AS2.  
CONNECTING THE AS2/S (see Illustration 5)  
Illustration 5: AS2/S Connections and Controls  
AL2 and AL2/S Automatic Secondary Source Selector (Line-Level)  
The AL2 and AL2/S function identically to the AS2 and AS2/S except that they  
switch line-level audio signals instead of speaker-level audio signals. Typical  
applications would be switching between two different inputs in a whole-  
home audio system or home theater system, or combining two different audio  
systems. Features and operation are identical to the AS2 and AS2/S, except that  
the AL2 and AL2/S operate at line level.

LS2 and LR2 Balanced Audio Sender and Receiver

CONTROL INPUT  
12VDC 100mA  
The LS2 and LR2 are the most efficient and highest-quality way to distribute  
audio throughout a residential or commercial system. The LS2 converts  
typical line-level audio signals to balanced configuration, allowing them to be  
sent long distances and in close proximity to sources of noise interference  
without inducing noise or high-frequency roll-off.

INPUT B

SPEAKER LEVEL  
+L– –R+  
As a general rule of thumb, a balanced signal should be used for all but short  
lengths of audio cable (under 20 feet) and wherever the possibility of signal  
interference is likely. This includes where the audio signal passes near  
dimmers, transformers, fluorescent and neon lights, or along the same  
pathways as house current.  
OUTPUT  
Output  
Active circuitry in the LS2 sends the balanced signal to the LR2, which  
converts it back to an unbalanced line level signal that can be connected to the  
audio component. The LS2 and LR2 must always be used with each other  
unless the audio equipment has balanced inputs or outputs (such as profes-  
sional sound or recording equipment). In this situation the LS2 could be used  
as an unbalanced-to-balanced converter and the LR2 could be used as a  
balanced-to-unbalanced converter. The LS2 can also be used with the 275 SE  
and ASAP2 SAT amplifiers with an LR1 SAT module (part# 91815) installed.  
The AS2/S is aslave’ unit that operates similar to the AS2, except that its input  
switching is controlled by an external voltage source. In most systems the  
control voltage will be supplied by the Control Output connector of an  
AS2 unit, but any 12V DC source (with a minimum of 80mA of current) that  
switches on and off can be used as a control trigger.  
1. Connect the left & right speaker outputs of the main (default) amplifier to the  
AS2/S’ Input A terminals; connect the left & right speaker outputs of the  
remote amplifier to the AS2/S’ Input B terminals (see Step 1 of Connecting  
The AS2).  
VT1 Video Trigger  
The VT1 provides a 12V DC signal when a video sync pulse is detected (pic-  
ture or blue screen). This can be useful in triggering any component requir-  
ing a 12V signal. An LED indicates when the unit is active. A detachable 12V  
DC power supply is included.  
Note: The AS2/S can be used with amplifiers up to 100 watts RMS/channel.  
2. Connect the AS2/S’ left & right Outputs to the local zone speakers.  
3. Connect the switching 12V source to the AS2/S’ Control Input connector.  
You can use any 2-conductor wire (16ga ~ 22ga) to connect the AS2/S  
Control Input terminals to the Control Output terminals of an AS2.  
RFGI1 Radio-Frequency Ground Loop Isolator  
A passive device, the RFGI 1 is used to break a ground loop that can occur  
when using a cable TV or antenna feed along with AC system grounding. The  
RFGI1 blocks low frequency and DC by capacitor-coupling the shield and the  
center conductor of any RF cable connected through it. This prevents the  
occurrence of low-frequency humming and TV screen hum bars. The RFGI1  
connects between the main cable TV feed and the cable distribution box, RF  
amplifier, cable converter, VCR or TV. F-connections are used on each side for  
a secure and reliable termination. Because it does not allow any RF leakage,  
the RFGI1 is a superior termination compared to a 75-to-300-to-75 ohm bal-  
anced connection.  
Caution: Do not short the ‘+’ and ‘–’ terminals together on the AS2 or AS2/S  
Control Outputs/Inputs.
