INTRODUCTION

The SAS-1 is an automatic A-B switching system designed to replace manually operated A-B switches. It automatically switches from A to B when a signal is present at its B input. The unit’s three switching sections can switch three different kinds of signals: Line-level audio, composite video and speaker level audio. The SAS-1 switches each of these sections at the same time, allowing simultaneous control of these signals if needed. Five-way speaker wire binding posts are provided for the speaker level switching and RCA-type phono jacks are provided for the line-level audio/video switching.

FEATURES

Replaces manually operated A-B switches

Audio power handling: 600W per channel

SAS-1 is capable of switching speaker-level, line-level audio, and composite video signals

May be configured to use any of three trigger signals: audio, video, or voltage

Exclusive signal-detection circuitry ensures reliable operation

Control input for voltage activation (5V-30V AC/DC at 20mA)

12Volt control output for activating other Niles devices such as a SPK-1, AVS-2, AC-3, APC-2 or RFS-1

Normally Open (N.O.) relay contacts for controlling devices such as electric screens, lifts and drapes

Relay contacts rated at one amp, 30V max., AC/DC

Premium gold-plated RCA connectors and five-way, nickel-plated binding posts

OPERATION

There are two ways to trigger the SAS-1 switch: a signal sensing mode (1) and a voltage control mode (2).

1.In the signal sensing mode, the SAS-1 automatically switches from A to B when a signal is present at input B. A sensitivity control is provided for setting the amount of input level (trigger threshold) needed to activate the switch. The B input will have priority as long as a signal remains at its input. Depending upon the setting of the delay control, the unit switches from B back to A anywhere between ¼ of a second to 30 seconds after the trigger signal (input B) is removed. The SAS-1 can be programmed to trigger from the speaker-level, line-level or video sources. At DIP switch is provided for the programming.

2.In the voltage control mode, applying 5 to 24 volts AC or DC to the control input connector will trigger the SAS-1 to switch. There are several ways this feature can be used:

a)An included wall mount, 16Volt AC transformer (Part# XF00008) can be used as the control voltage source. Plugging the AC transformer into the switched AC outlet of an AM/FM receiver will trigger the SAS-1 to switch every time the receiver is turned on.

b)A toggle switch wired between the output of the AC transformer and the “Control IN” jack can be used as a manual trigger.

c)Any voltage source between 5 to 24 Volts AC or DC can be used to activate the SAS-1. For example, a 12Volt control signal from a home automation system can trigger the SAS-1.

A control output connector is also provided. It has four screw terminals and provides two different outputs. Two of the terminals provide a set of normally open, dry relay contacts and the other two provide 12Volt DC output.

The set of dry contacts “close” whenever the switching section of the SAS-1 is activated. They will remain “closed” as long as the signal that triggered the SAS-1 is present. Depending on the setting of the delay control, they will “open” anywhere between ¼ of a second to 30 seconds after the signal that triggered the SAS-1 is removed. With this feature, the SAS-1 can activate television lift systems, operate electric projector screens, control lighting systems, etc.

2

The 12Volts DC is present at the other two terminals whenever the switching section of the SAS-1 is activated. Depending on the setting of the Delay Control, the voltage turns off anywhere between ¼ of a second to 30 seconds after the signal that triggered the SAS-1 is

removed. This feature is provided as an interface when using the SAS-1 to control other Niles switching devices such as the AVS-2, SPK-1 and AC-3. refer to the section titled “System Expansion” for more details.

INSTALLATION

The SAS-1 should be installed near the equipment or sources you are going to control. An unswitched AC outlet is required for the wall mount AC transformer that powers the unit. The SAS-1 can be tucked away behind the equipment or attached to the mounting surface using supplied hardware.

CONNECTIONS

Refer to Figure 1 on the following page for hookup diagram.

PROGRAMMING

Once the line-level or speaker-level sources have been connected, the SAS-1 must be programmed for the source(s)) you are going to use as a trigger for the switch.

AUDIO ACTIVATED MODE – SPEAKER AND/OR LINE-LEVEL

If you want the SAS-1 to activate when ever a speaker-level signal is present at the “B” input, locate the DIP switch on the front panel and move the slide switch underneath the letter “S” up. Use a small screwdriver or paper clip to move the switch.

If you want the SAS-1 to activate whenever a line-level audio signal is present “B,” move the slide switch underneath the letter “A” up.

NOTE: IF YOU ARE USING SAS-1 TO SIMULTANEOUSLY SWITCH BOTH LINE-LEVEL AND SPEAKERLEVEL SIGNALS AND WANT THE UNIT TO TRIGGER FROM EITHER SOURCE, MOVE BOTH THE “A” SWITCH AND THE “S” SWITCH UP.

VIDEO-ACTIVATED MODE

If you want the SAS-1 to activate whenever a video signal is present at “B,” move the slide switch labeled “V” up.
