When completely independent Power Scale controls are needed, as in channel switching amps, a more sophisticated circuit than the PSB is required. The PS-Dual provides this versatility, with foot-switchable access to the PS controls. The switch control circuitry, footswitch and jacks are included, and can control other shunt-connected jfet switches in the audio path. The PS-Dual can operate with any PSK-1/2/3 basic kit, regardless of other accessories, e.g., the FTC or PMS. Some players desire three or four Power Scale controls, where some may be used as simple volume boosts. This is an extension of the circuitry found in the PS-DUAL, but requires a completely different footswitch interface. The PS-TRIPLE and PS-QUAD use an IC to provide direct-random-access from one setting to another, with automatic cancellation of the previous setting. Momentary footswitch buttons are used. A pair of 5-pin DIN sockets is also provided, and the user must make up a 5-wire cable with the matching ends. Other cable types are possible, but that choice is up to the kit builder.
