Aprašymas

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.

Monitor/Remote Jack

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