There’s no reason to limit yourself to 2 channels, even if space is tight. The WA-4×3 is a 4-channel amp you can use any way you like: for a 4-zone system, triphonic, quadraphonic or simply stereo. The impressive number of configurations available makes it an extremely versatile asset. Equally at home in a fixed installation or as a mobile PA system, it offers everything a stereo amp should, but with 4 channels. <\/p>\n
