Schematic needed for Niles SAS-1

[woostersoz]

I recently purchased a Niles SAS-1 Source switcher from ebay.. The speaker level switching works fine but when I try to use the Voltage switching from the switched outlet of my Pioneer Elite receiver, the switching stops working - i.e. regardless of volume level etc, the SAS-1 refuses to switch to the receiver.

Does anyone have a schematic or any other hints that can help me troubleshoot ? I am capable of opening up the unit and getting going with a DMM and soldering iron.

Thanks in advance...

Post a picture of the back of the unit to jog my memory.

I am thinking the SAS uses line level switching as well as speaker level. In other words... you can send speaker level signal or line level signal from two sources and it will switch to the live source and pass that source.

You have got me lost when you are mentioning using the switched outlet from your unit. Are you trying to power the unit from the switched AC outlet from your receiver?

Thanks - I have someone looking at this now...
FYI - apart from line and speaker level, the SAS-1 also has voltage based switching and that is why I connected the switched outlet of my receiver to the Control In - not the power

From what I just found it can take 5-30volts AC or DC for a control input for turn on. I hope you didn't put 120v to try to activate it.

thanks for your info - i did not input 120V into the control input - the wall wart that comes with the unit outputs 16VAC and that's what i used

Yes, that will power up the unit. To control switching using a voltage the voltage must be applied to the control input.

Try using your wart to power the unit. Now take a 9 volt battery and apply that voltage to the control input port and see if it switches.
