By BUILDER Magazine Staff. SpeakerCraft's EZ-Pad Series of keypads have been shipping for the past couple of months. The EZ-Pad lets homeowners control music from any location in the home. The master keypad can select audio and video sources, control component functions, control infrared signals to remote devices, and turn systems on or off. Retail prices range from $40 for the function keypad, which controls sources and basic on/off operations, to $400 for the full-featured EZ-Pad Controller.
