Parasound 2125 V.2 manual AC Power Cord, Triggering multiple devices, Volt Input Jacks

12 Volt Input Jacks

The Model 2125 v.2 12V input uses a 3.5mm jack (mono). To use the 12V trigger, insert the trigger wire plug into this jack and the plug at the wire’s other end into the AV receiver or preamp’s 12V output jack. We have included a 3.5mm to 3.5mm trigger wire as well as a 3.5mm to 2.5mm trigger wire.

Note: If the controller’s trigger output is a + and – terminal, you can cut the 3.5mm plug off one end of the included trigger wire and attach the bare wires to these terminals. The trigger plug tip is + (positive) and its sleeve – (negative).

12V Loop Out Jack

The Trigger Out jack lets you loop or ―daisy-chain‖ the incoming trigger voltage to an additional Model 2125 v.2 or another component(s).

Triggering multiple devices

The total load on your preamp’s trigger output(s) is the sum of the trigger current drawn by each of the components you’ve looped together. The Model 2125 v.2 trigger circuit draws a negligible 15 mA. Check the maximum capacity of your AV receiver, processor or home controller’s trigger outputs so you do not overload them by connecting too many power amplifiers. Typical ratings are 50mA to 100mA.

3.5mm and 2.5mm trigger jacks

Some other Parasound power amplifiers and preamplifiers might have 2.5mm ―sub-mini‖ trigger jacks. To use the Model 2125 v.2 with products that use a 2.5mm jack we have included a trigger wire with a 3.5mm plug at one end and a 2.5mm plug at the other end.

AC Power Cord

Model 2125 v.2 is supplied with a high quality IEC standard AC cord. Please connect it directly to an AC wall outlet or power conditioner that is always ―live.‖ If possible, plug your Model 2125 v.2 into the same AC outlet that your preamplifier is plugged into. If different AC outlets are used for the Model 2125 v.2 and the preamplifier the ground potential between the two outlets might be higher or lower, resulting in audible hum.
