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.
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.
The rear panel provides a Monitor/Remote jack that allows the amp to be monitored and controlled from an external device.
