I forgot to mention more detail about the 12V Trigger Inputs
. Not a very "exciting" topic, but let me go over it now:
Via the L2 Preamplifier, you can turn ON/OFF the L2 Monoblocks (or another power amp with 12V trigger inputs) using the dual 12V Trigger outputs of the L2 Preamp.
For both components, I chose Neutrik 1/4" (6.35mm) locking TRS panel mount jacks. I know it is more common (and less expensive) to use the the smaller 3.5mm jacks (especially the cheap PCB mount jacks), but I found that none
of them are nearly as rugged as this 1/4" panel-mount locking jack.
So depending on the length of your interconnects from L2 Preamp to L2 Monoblocks, you want to use approx. the same length TRS cables for the 12V triggers for each monoblcok. I tested these, and they are very well made, readily available in many lengths, and at a great price!https://www.monoprice.com/product?c_id=115&cp_id=11509&cs_id=1150901&p_id=4792&seq=1&format=2

NOTE: If you are outside the USA, it is probably much more convenient that I order these cables for you and include them with your L2. Just let me know in the comments section of your order.L2's 12V triggers (simple explanation):
When you turn ON your L2 Preamp and press the TRIG button on the front panel, the two 12V trigger outputs are turned ON. This turns on/off the L2 Monoblocks without you having to turn on their ON/OFF switch.
L2 Preamp saves the 12V trigger setting when you turn it ON/OFF. This way, you can turn everything ON/OFF together via the PWR button on the L2 Preamp remote (or front panel). Simple.
[From a customer looking to use two pair of L2 Monoblocks for bi-amping his speakers]. How do I connect the triggers for 2 pair of L2 Monoblcocks (4 monoblocks)?A:
A TRS Y-cable will do the trick. One for the LEFT channel trigger output (to turn on the two LEFT monoblocks in a bi-amp system), and one for the RIGHT channel.
This way, you can turn ON your L2 Preamp and all 4 monoblock with just a press of a button on the remote.
And if you don't want to use a Y adapter, they make cables that go from one TRS male plug to two TRS male plugs.
And yes, I have seen cables that convert TRS male to 3 TRS females in case you want to tri-amp with 3 pairs of L2 Monoblocks.
Each L2 Monoblock trigger input only draws 45mA, and each L2 Preamp trigger output can provide 250mA continuous.Q:
Does the 12V trigger cable have any influence on sound quality?A:
No - not at all. It is just a low current 12V DC on/off signal that turns on/off a power relay (instead of manually turning on/off the power rocker switch).
I think that covers it!
