Lavalier condenser for voice and guitar

The PRO 70 is a miniature condenser microphone built for vocal and acoustic guitar use. Its cardioid pattern rejects sound from the sides and rear to isolate the intended source. The capsule weighs 0.3 oz and connects through a permanently attached 1.8 m cable to a power module.

Clothing clip and guitar adapter included

A lavalier clothing clip secures the microphone for hands-free speaking applications. An instrument adapter allows the same capsule to mount on an acoustic guitar for close-miked pickup. Both accessories are supplied in the box so the user can switch between voice and instrument setups without extra purchases.

Battery or phantom power with roll-off switch

The power module accepts a 1.5 V AA cell delivering 1200 hours typical life or 11 to 52 V phantom power at 2 mA. A three-position switch selects off, flat response or an 80 Hz roll-off at 18 dB per octave to reduce low-frequency rumble. The gold-plated XLRM connector ensures corrosion-resistant contact with the mixer or recorder.

Questions about this item

How often will the AA battery in the power module need replacing during regular use?

The 1.5 V AA battery draws 0.4 mA and typically lasts 1200 hours before it needs changing.

What is the maximum sound pressure level the capsule can handle before distortion becomes audible?

The microphone accepts up to 123 dB SPL at 1 kHz with 1 % THD, so very loud sources are the first limit reached.

How much heat or noise does the unit produce when left on for a full day of recording?

The condenser element and battery-powered module generate no audible noise and negligible heat during continuous operation.
