Allo Relay Attenuator - 10k Stereo [Discontinued] _QWIIC This complete kit contains:Relay Attenuator (RA) is a hardware volume control. It takes input from DAC shields and attenuates the output by relay switching. This is Allo's Relay Attenuator, designed to be used with the Piano 2. 1 & Boss DACs! The Relay Attenuator has been designed for Audio attenuation after Piano DAC output, and features a 1dB step size. It's a compact circuit, featuring just 6 tiny relays, implementing a 64 step logarithmic stereo attenuation. The 64 steps of
