[QUOTE="Ivan Beaver, post: 145783, member: 30"] Re: Powering Danley with Powersoft. Help required Here is a little explanation why we have impedance switching on various cabinets. It gives the user various opportunities to power the cabinets, based on specific needs. In this case, each of the drivers is 4 ohms. Some people don't like to load their amps down below 4 ohms. I won't go into the various reasons now. This would mean they need to operate it in 2x 4 ohm mode. Each amp channel would drive 1 loudspeaker driver. In the 1x2 ohm mode-the drivers are in parallel, so a single amp channel (that is stable at 2 ohms) could drive the cabinet. In some cases people are powering the cabinet with older less powerful amplifiers. In the 2x4 ohm mode, this allows older (2 ohm capable) amps to be bridged into each driver. In some installations, there are very long speaker cable runs to the loudspeakers. The 2x4 ohm mode would have less loss over the cable length. Although it would require a second cable to do this. But in some cases existing cables must be reused. It is all a matter of compromises. So the switchable impedance give you some choices depending on application and needs. Agreed that it does add some confusion. [/QUOTE]
