Monitor Audio IWA-250 Subwoofer Amplifier (Each)

The IWA-250, a switch mode amplifier, is a slim, powerful dedicated design in a heavy-duty 1U rack mount case. Delivering up to 250watts into 4 ohms, a single IWA-250 will power single or dual ISW-10s to provide higher power levels for larger rooms or to meet customer demands. 

The IWA-250 can be configured to switch on automatically using input signal sensing, or by using the preferred 12v trigger link from an AVR or system source. The IWA-250 will then automatically be switched on and off with the AVR, TV or system remote control handset. 

The amplifier utilises a cool running Class D power stage driven by a PWM with integrated DSP. All filtering and functionality are controlled in the software for precise and reliable operation. It offers a choice of single LFE, balanced XLR and stereo RCA inputs. 

Output connection is made via two sets of push type terminals to provide connection to one or a pair of IWS-10 drivers. The front panel provides access to all control features for easy adjustment when fitted into a rack bay. An EQ switch provides a selection of music, movie and impact presets for the ideal response in-room. There is also an enclosure switch to calibrate the drive characteristics when the IWS-10 is used within or without the IWB-10 back box.
