The XM series multi-channel power amplifiers are ideal for theater, hall, and conference room installations. The lineup includes 80W ? 4 and 180W ? 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.
* Switchable stereo, parallel, or bridged operation.
* Versatile connectivity and high-pass filters for a variety of applications.
* Distribution drive capability for parallel multi-speakers systems (XM4180).
* Monitor/Remote connector for remote monitoring and control.
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.
Versatile Input/Output Connectivity
Two types of input jacks are provided; balanced XLR types and Euroblock jacks for easy, secure input connection. Output connections are made via five-way binding posts. A high pass filter with a selectable 20 Hz or 55 Hz roll-off frequency is also provided. Precision attenuators and independent indicators are provided for each channel, allowing accurate level setup and status monitoring.
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.
Monitor/Remote Jack
The rear panel provides a Monitor/Remote jack that allows the amp to be monitored and controlled from an external device.
