Monitor Audio IWA-250 Amplifier

Monitor Audio

Monitor Audio is a British owned specialist in hi-fi loudspeaker design, incorporating stereo and surround sound systems, and a range of sonically matched installation speakers for ultra discreet high quality sound around the home and outside. WE REGRET THAT MONITOR AUDIO PRODUCTS ARE FOR SALE IN THE UK AND CHANNEL ISLANDS ONLY.


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.
