The Model SM7B dynamic microphone has a smooth, flat, wide-range frequency response appropriate for music and speech in all professional audio applications. It features excellent shielding against electromagnetic hum generated by computer monitors, neon lights, and other electrical devices. In addition to its standard windscreen, it also includes the A7WS windscreen for close-talk applications.
The SM7B is an outstanding choice for the following applications:
Speak directly into the mic, 1 to 6 inches (2.54 to 15 cm) away to block off-axis noise. For a warmer bass response, move closer to the microphone. For less bass, move the microphone away from you.
Use the enclosed velcro tie to secure the cable.
Use the standard windscreen for general voice and instrumental applications.
When you speak, you may hear vocal pops from some consonant sounds (known as plosives). To prevent more plosive sounds and wind noise, you can use the larger A7WS windscreen.
The default setup for the SM7B is for a boom mount. To set up the SM7B for a microphone stand:
Note: If the tightening nuts do not hold the microphone in place, you may need to re-position the brass sleeves and the washers.
① Tightening nut
② Fitted washer
③ Lock washer
④ Brass washers
⑤ Brass sleeve
⑥ Mounting bracket
⑦ Plastic washer
⑧ Response switches
⑨ Switch cover
The SM7B has a sensitivity rating at -59 dB and requires more gain than what most entry-level or mid-tier preamplifiers can deliver. Use an inline boost amplifier or stronger preamp if your preamp does not have more than 60 dB of gain.
To mount the microphone on a 3/8 in. stand, insert the included brass stand adapter and tighten it with a coin or screwdriver.
Important: Make sure that the slots on the adapter face outward.
You can use a pen, pencil, or screwdriver to move the switches on the back panel. This adjusts the frequency response.
Note: You can change the switch settings while the mic is in use or plugged in.
Flat response: This default setting works for most applications.
Bass rolloff: If you want to reduce the bass, push the left switch down. This can help lower background hum from A/C, HVAC, or traffic.
Presence boost: If you want a brighter sound in the mid-range frequencies, push the right switch up. This can help improve vocal clarity.
