Burl Audio B1 – 500 Series Microphone Preamp DI



SKU: B1-MIC-PRE Categories: , , ,

Step Back– Here come the B1and B1D …Introducing the B1 and B1D Mic Pre Amps from Burl Audio. Based upon the API 500 collection form aspect, the B1 was created to compliment the B2 Bomber ADC, and give you multi-channel pleasure. With the proprietary BX3 input transformer and BX2 output transformer, the B1 Mic Pre delivers warmth with depth and quality. The B1D is the same as the B1 except that it has an all iron BX4 output transformer offering it a more horrifying rock tone. An all discrete transistor, class-A, direct coupled, capacitor free circuit road, provides the B1amazing punch on drums, beautiful tonality on guitars, and warmth with presence on vocals.

The B1 and B1D come full with both Gain and Level controls. If you want that hefty, gainy tone, crank up the stepped gain control and offset that with the level control. If clean tone is your thing, turn the gain down and crank up the level. For ribbon mics and additional reasonable impedance sources, the B1 has a transformer paired impedance select. The B1 was carefully tested with the popular Royer R-121 in the reduced impedance setting, and we think it appears pretty f *** ing bitchin” on guitar amps. The B1 gets the very best from any sort of mic, whether it be vibrant, condenser or bow.

Usage the B1’s 1/4″ instrument/line input on the front panel, plug in, crank up the gain and go. The PAD switch permits hot signals and well balanced line inputs through the mic XLR on the back panel. Run your tracks or mixes with the B1 for warmth and glue. The B1 was designed to rock. Run several B1 channels for your rhythm tracks and you are there. Replace EQ and compression with true analog PHAT. Run your main tracks through the B1 mic pre, follow with a B2 Bomber ADC and that’s about all you will require.
