The Monitor Audio IWA-250 is a switch mode subwoofer amplifier in a slim, heavy-duty 1U rack mount case. Delivering up to 250 watts into 4 ohms, a single IWA-250 will power one or two IWS-10 in-wall subwoofer drivers, making it suitable for both the IW-SUB-S and IW-SUB-T systems.
The IWA-250 can be configured to switch on automatically using input signal sensing, or via a preferred 12V trigger link from an AV receiver or system source. The amplifier utilises a cool running Class D power stage driven by a PWM supply with integrated DSP. Filtering and functionality are controlled in software for precise and reliable operation.
The IWA-250 offers a choice of single LFE, balanced XLR and stereo RCA inputs. Output connection is made via two sets of push-type terminals. The front panel allows access to all control features for easy adjustment when rack-mounted. An EQ switch offers music, movie and impact presets, and an enclosure switch calibrates drive characteristics when the IWS-10 is used with or without the IWB-10 back box.
