B1D 500 Series Microphone Pre-Amp
The Burl Audio B1D 500 Series Microphone Pre-Amp is based on the API 500 series form factor, the B1 is meant to compliment the B2 BOMBER ADC and the B80 MOTHERSHIP with multi-channel versatility. The B1D contains the Burl BX3 input transformer, an all iron BX4 output transformer and an all discrete transistor, class-A, direct coupled, capacitor free circuit path and give your sound a straight ahead rock tone. For comparison, the B1 contains a nickel BX2 output transformer providing a tone with more warmth and clarity.
Both the B1 and B1D include Gain and Level controls to let you swing from a heavy gain rock tone to something more smooth and clean, even when coupled with a low impedance ribbon microphone.
The 1/4” instrument/line input on the front panel, mic XLR on the back panel, and PAD switch allow for hot signals and balanced line inputs. Run your tracks or mixes through the B1 to glue your sound together.
