The Whitestone Audio Instruments P331 Tube Loading Amplifier was developed to bring professional tracking, mix and mastering engineers versatile, elegant, precise and repeatable audio circuit variation. There’s nothing like running a signal through a well-designed piece of analog gear, at “unity” gain without any “processing” applied at all. Simply exploiting the sound of some of these analog input and output gain circuits is often-times just the thing to bring subtle life or organic size and depth to recorded audio. The P331 is designed to enhance any audio signal…your individual tracks, on your mix-buss or in your mastering chain.

Key Features:

• LOADING: designed to coerce an audio signal to hit the tube at different points on its response curve
• LIFT: gentle parallel filter that enhances the highs, lows or both the highs and lows of the signal.  
• XFORMER: provides the purest, cleanest and most unaffected audio path through the unit. 
• OUTPUT GAIN: low distortion, fully balanced solid state amplifier for the output gain section.
• HARD-WIRE BYPASS: Each section of the P331 (with the exception of the Loading circuit) can be fully hard-wire bypassed.
