Bring local control to distributed audio with the Russound A-K4 amplified keypad. Built for A-BUS environments, it gives users straightforward access to speaker and volume control without adding complexity at the rack. The keypad also passes IR commands to connected source equipment, helping keep source control available where it matters most. A variable line-level output expands installation options by supporting an external amplifier or powered subwoofer, making the A-K4 useful in rooms that need more than basic zone volume adjustment. The LED indicator provides clear status feedback, while 24 V DC input supports integration into compatible multiroom audio systems. For integrators, the value is in clean control and flexible deployment. The A-K4 fits A-BUS hubs, A-BUS-ready receivers, and A-BUS subzones on multiroom controllers, making it a practical choice for residential and light commercial audio projects where dependable wall-mounted control is preferred over app-only operation.
