The third component in the in-wall subwoofer system is the IWA-250 switch mode amplifier: a slim, powerful dedicated design in a heavy-duty 1U rack mount case. Delivering up to 250 watts into 4 ohms, a single IWA-250 will power single or dual IWS-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 supply with integrated DSP. Filtering and functionality are controlled in the 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 to provide connection to one or a pair of IWS-10 drivers. The front panel allows access to all control features for easy adjustment when fitted into a rack bay. An EQ switch offers 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.
Because positioning of a speaker is so important in determining the sound that you hear, we have integrated a Digital Signal Processor into the i-decks which automatically adjusts the output based on the environment in which the i-deck has been placed. This intuitive process takes place automatically each time you power up the i-deck at the mains so you always hear the best possible sound, no matter what space restrictions you are working with.
