ADJUSTING THE SAS-1
The Sensitivity Control adjusts the amount of input level needed to trigger the switch. The
threshold may be set anywhere between 15mv and 300mv for line-level audio signals and
.1 watt to 4 watts for speaker-level signals. Adjusting the control clockwise will increase the
sensitivity, lowering the trigger threshold. Adjusting the control counter-clockwise will decrease
the sensitivity, increasing the trigger threshold.
Once the sources to be switched have been connected to the SAS-1, activate the source
connected to “B” input and adjust the sensitivity control until the SAS-1 is triggered at the
desired level. You will hear the relays in the SAS-1 “click” when it is triggered.
NOTE: THE FACTORY SETTING OF THE SENSITIVITY CONTROL IS MAXIMUM (FULLY CLOCKWISE). IF
YOU WANT THE SAS-1 TO TRIGGER AT THE SLIGHTEST INPUT LEVEL, LEAVE THE CONTROL AT THIS
SETTING.
The Delay Control adjusts the amount of time the SAS-1 will switch from B back to A once the
trigger signal is removed. The delay time may be set anywhere between ¼ of a second to 30
seconds. Adjusting the control clockwise will increase the delay time.
Once the sources have been connected, and the sensitivity control has been adjusted, activate
the source connected to the “B” input. You will hear the relays in the SAS-1 click when
triggered. Adjust the Delay Control and then turn off the “B” source, noting the time the relays in
the SAS-1 “click” again. The time between the clicks is the delay time. Repeat the process until
the delay is set to the desired time.
NOTE: THE FACTORY SETTING OF THE DELAY CONTROL IS APPROXIMATELY 15 SECONDS. THE
SETTING TAKES INTO ACCOUNT THAT CERTAIN EVENTS CAN OCCUR DURING THE PLAYBACK OF A
SOURCE, SUCH AS THE TIME A CD PLAYER TAKES TO CHANGE DISCS, A LASERDISC PLAYER TAKES
TO SWITCH SIDES OR A CASSETTE DECK TAKES TO REVERSE PLAY. SETTING THE DELAY CONTROL
FOR TOO SHORT A TIME MAY CAUSE THE SAS-1 TO “DROP OUT” PREMATURELY, INTERRUPTING
PLAYBACK OF THE “B” SOURCE.
USING THE CONTROL IN
Applying 5 to 24 volts (AC or DC) to the CONTROL-IN jack will immediately trigger the SAS-1 to
switch from A to B. Depending on the setting of the Delay Control, the SAS-1 will return to INPUT
A between ¼ of a second to 30 seconds after the control voltage is removed. The CONTROL IN
jack is not affected by the position of the DIP switches.
A wall mount, 16Volt AC transformer can be used as the control voltage source. A transformer of
this type is included.
