The PreSonus PD-70 Dynamic Broadcast Microphone is specifically designed for capturing the human voice and improving intelligibility, even in acoustically unfriendly spaces. The cardioid pickup pattern reduces the amount of extraneous and unwanted background noise entering the mic’s sides and back while focusing on voices in front of it—just what you want for podcasts or radio broadcasts.
The all-metal PD-70 is an end-address dynamic mic with an integrated (yet removable) foam windscreen and a simple, compact mechanical design that will fit and look great on the smallest of desktops. You can thread the mount onto a standard mic desk stand or boom, and connect a cable to any preamp using its gold-pinned XLR output jack. It comes ready to use with a gimbal-style integrated yoke mount that allows tilting the mic up or down to aim it precisely. Once in position, it has a single knob to lock it down. It does not get any simpler than this!
I tried the PD-70 in my studio as a vocal mic feeding a Retro Instruments 500PRE preamp; I also put it up for a Zoom meeting into an SSL 2 USB Audio Interface.
The PD-70 has a frequency response of 20 Hz to 20 kHz with a shelving boost starting at about 1.5 kHz and extending out to 10. I can hear that little boost in the midrange—especially on small computer speakers—and it does impart a certain gravitas and authority to speaking voices. I found it helpful for somber-sounding online speakers, as long as they stayed close in front of the mic to maintain a fat-sounding “lift in the bass” due to the cardioid proximity effect.
At the same time, the PD-70 suppresses p-pops better than some other dynamic mic I have, with or without a pop filter. Removing the foam windscreen, you can see a resemblance to the internal mechanical design of the Shure SM7B dynamic mic.
Paired with the 500PRE (tube-based preamp), the sound was rich and noise-free, and I would have no issues using the PD-70 for a loud lead vocal track—provided the singer could stay aimed at the mic. The SSL 2 USB preamp worked well except for very quiet singing, when that unit starts to run out of available mic gain.
The PreSonus PD-70 wins as a workhorse of a mic that will improve the sound of anyone doing online podcasting, Internet radio or hosting/participating in Zoom meetings.
