We recommend the use of high-quality cables terminated with spade or ring lugs that will fit the amplifier’s binding posts. These will provide the best conductivity and the most reliable connection. We advise against the use of pin connectors, banana plugs or bare-wire connections.
- Page 9 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.

Page 10: Configuring The Channels
Configuring the channels The Master Power 3+ and Master Power 2+ amplifiers offer several configuration options that allow you to combine incoming signals and amp channels, and to filter high- or low-frequency signals out of any channel. All can be easily accessed through the Crossover Adjustment panel on the back. - Page 11 Bridge mode Bridge mode combines two channels to increase their total output to 1,200 watts into 8 ohms. With the Master Power 3+, channels 2 and 3 are bridged. With the Master Power 2+, channels 1 and 2 are bridged. To put the amp in bridge mode, flip the bottom two toggle switches to the left.
