Burl Audio B1 Mic Preamp/DI
The B1 and B1D mic preamps from BURL AUDIO are based on the API 500 series form factor. With the proprietary BX3 input transformer and BX2 (BX4 on B1D) output transformer, the B1 MIC PRE delivers warmth with depth and clarity.
An all discrete transistor, class-A, direct coupled, capacitor free circuit path, gives the B1 amazing punch on drums, beautiful tonality on guitars, and warmth with presence on vocals.
The B1 comes complete with both Gain and Level controls. If you want heavy, 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 other low impedance sources, the B1 has a transformer coupled impedance select.
The B1 gets the best out of any microphone, whether it be dynamic, condenser or ribbon. Use the B1’s 1/4” instrument/line input on the front panel, crank up the gain and go. The PAD switch allows for hot signals and balanced line inputs through the mic XLR on the back panel. Run your tracks or mixes through the B1 for warmth and glue.
The B1 was designed to rock. Run multiple B1 channels for your rhythm tracks and Bob's yer uncle. Replace EQ and compression with true analog PHAT.
