Standby mode when voltage is applied from the triggering
unit. Note that a 3.5mm mono mini-plug with a positive tip
should be used for the connection.
11 AC Power Cord:
Connect this plug to a non-switched
AC outlet. Due to the high-current draw of the Signature 1.5,
it is NOT recommended that the accessory outputs on the
back of audio/video components be used to power this
product.
