SLV Black Series Front Panel Board – BL7 / BL9 Volume & LED PCB ( VERSION 1 )

The SLV BL-YA-2U-LED is the standard front-end control interface designed for the 2U chassis of the BL7 and BL9 professional amplifiers. This assembly consists of a main control board and a secondary display board, allowing for independent dual-channel gain adjustment and comprehensive visual feedback on the amplifier's operating status. It is engineered to maintain signal integrity while providing the rugged reliability required for touring and installation audio.
