James Mono 1000W (4ohm/70V) Sub Amplifier


The James M1000 mono subwoofer amplifier is a 2U, high efficiency, class D design producing over 1000W of RMS power into both 4 ohm AND 70 volt loads.  The M1000 is a hybrid design with an internal linear power supply to provide large reserve current to the class D output stage, ensuring powerful dynamics and tight bass response.  A full feature DSP front end can be configured via the 5-button controller and 2-line display on the front panel.  Firmware updates can be uploaded via the USB connector.

On the rear, inputs include left/right high-level binding posts for use with speaker output signals, left/right RCA and Left/right balanced XLR's.  A pair of left/right RCA outputs provide buffered zero gain signals to feed other amplifiers - useful for connecting multiple M1000's in home theater applications or an additional 70V stereo amplifier in 70V landscape applications.

A smoked front panel display hides the LED indicators which actually use printed words for "Power", Standby", "Clip" and "Signal".  The "Clip" indicator show amplifier clipping, or when the limiter is set, show the amplifier is limiting.  The "Signal" indicator flashes on very low input signals to indicate the presence of any input signal - great for troubleshooting.
Within the DSP, the user can save up to 3 complete setups, which can be recalled via the front panel or via IR codes - great for unique setting for movies or music for example.
