12-volt trigger input/output

These 3.5mm jacks allow the amplifier to be turned on or off automatically by a preamp or

other device that has a 12-volt trigger output, and also allow the 12-volt trigger output

signal to be relayed to other components (such as a second Master Power series amplifier).

To use the 12-volt trigger feature with the Master Power series amplifier, connect a cable

tipped with 3.5mm plugs (stereo or mono) to the trigger output of the preamp and the

trigger input of the amplifier. Plug in the amplifier and turn it on. You will notice the power

does not come on. However, when you turn on the preamp, the power amp should also turn

on. If it does not, check the owner's manual or the back panel of the preamp or other

device to make sure it outputs a 12-volt trigger signal. Some preamps require that the 12-

volt trigger output be activated through a control menu; if yours works this way, make sure

the trigger output is activated.

If you want to power up another component (such as another Master Power series

amplifier) when this amplifier powers up, connect a cable tipped with 3.5mm plugs (stereo

or mono) from the trigger output of this amplifier to the trigger input of the other

component.

RS-232 input

This DB9-type input allows the Master Power 3+ and Master Power 2+ amplifiers to be

controlled by home automation systems that use RS-232 protocol. Consult your Dan

D'Agostino Master Audio Systems dealer for more information.
