QRK-LED - Four LEDs for Amp Panel


In Stock
Product Code:


QRK-LED is an assembly of four LEDs on a PCB. This can be supported atop QRK-SW for a clean, modern appearance, or can be tied to the amplifier front panel using two brackets.

QRK-LED includes four 3mm round green LEDs.

The LEDs can be completely independent in their wiring to whatever circuit drives them, or they may be used in a common-anode configuration, or wired in series with taps available for current-steering control. Six links provide this versatility, typically installed three at a time. This allows the LED driver circuitry on QRK-LATCH, QRK-FET, QRK-RLY and QRK-VX to all be accommodated.

QRK-LED assembly is easy with its high-quality PCB and kit notes.

PCB size: 1.8 x 0.9", 46 x 23mm
