Yamaha XM4180 Power Amplifier
Compact, Lightweight 2U Amps Provide Four Channels of High-Power Amplification
The XM series multi-channel power amplifiers are ideal for theater, hall, and conference room installations. The lineup includes 80W x 4 and 180W x 4 models, meeting the needs of a wide variety of installed systems. The XM amplifiers are a compact 2U size and surprisingly lightweight, making them easy to handle and install. Switching power supplies deliver high output power while minimizing the unit's physical size. The XM series has monitor/remote jacks that allow external devices to be connected for status monitoring or control from a remote location.
Four High-Power Channels In One Amplifier
Both of these amps provide four independent channels of power amplification in convenient, manageable units (XM4180 = 180W, XM4080 = 80W). The XM4180 and XM4080 are suitable for a wide range of installed systems.
Stereo, Parallel, or Bridged Operation
Three operational modes can be selected as required: the stereo mode provides four independent channels of amplification, the parallel mode allows two mono sources to drive dual amplifiers each, and in the bridged mode two channels operate as a single high-power mono amp, effectively giving you two higher powered mono amps in one unit. The operating mode can be easily switched from the rear panel.
Distribution Drive Capability (XM4180)
The XM4180 is also capable of functioning as a distribution power amp that can drive multiple high-impedance speakers via 70V line output.
The rear panel provides a Monitor/Remote jack that allows the amp to be monitored and controlled from an external device.
