The Pure XLR Preamp has the same great sound and low noise circuitry as the Pure Preamp with the addition of a DI balanced XLR output and a phase switch. It was specially designed to complement the K&K line of Pure Pickups. However, due to its adjustable input gain and wide frequency range it will work with many more applications. The Pure XLR Preamp features +/-20 db bass, mid, and treble controls, plus an adjustable input gain control. Its noiseless circuitry provides unsurpassed clarity and power and the adjustable input gain allows you to dial in the precise amplification factor needed for your instrument. • MFSKU Pure XLR Preamp • UPC 0810604020195
