Jammin Pro B-20 PRO

Large Dual-Diaphragm Studio Condenser Microphone w/ 3 Polar Patterns, -10dB Pad, Low Roll-Off & More

We apologize

This item has been discontinued

The Jammin Pro B-20 PRO:

Due to its pressure gradient transducer and shock-mounted gold-sputtered dual-diaphragm capsule, the B-20 PRO provides a transparent sound with excellent transient response. It boasts a frequency response from 20 Hz to 20 kHz with just a slight boost in the presence range.

Polar Patterns:
The B-20 PRO has two selectable polar patterns: omni for capturing sound in all directions; and cardioid for picking up your source signal while rejecting off-axis sound. With its excellent transducer and gold-plated XLR output, the B-20 PRO is very neutral sounding and truly delivers on the promise of noise-free transmission.

The B-20 PRO also gives you a switchable -10dB pad to record high-level audio sources without distorting, as well as a low-cut filter to eliminate infrasonics caused by floor rumble and other turbulence. The B-20 PRO is built to be your go-to condenser mic for years to come. Its tough, nickel-plate brass body can withstand all the rigors of those late-night recording marathons. And with its aluminum foam-padded carrying case, it travels in safety and style.
