INTR ODUCTION Thank you for purchasing the Samson QE/QV Headset Microphone with the PM4 phantom power adaptor. These professional hands-free microphones are specially designed for performing musicians and dancers, sportscasters and aerobics instructors (the QE model is water resistant and is optimized for aero- bics use and high-humidity environments). Manufactured with extreme care and the highest quality components, they deliver an exceptionally clear, articulate sound, with superior rejection

INTR ODUCTION Should your QE/QV Headset or PM4 ever require servicing, a Return Authorization number (RA) must be obtained before shipping your unit to Samson. Without this number, the unit will not be accepted. Please call Samson at 1-800-3SAMSON (1-800-372-6766) for a Return Authorization number prior to shipping your unit. Please retain the original packing material and, if possible, return the QE/QV Headset in its original carton and packing materials. Samson Technologies Corp. 575 Underhill

FEATURES The Samson QE/QV Headset utilizes state-of-the-art headset microphone tech- nology and is engineered to the finest detail. Here are some of its main features: • Lightweight, low visibility design for unobtrusive use. • High quality electret condenser element delivers high output and exceptional sound quality. • Full range frequency response for clear, crisp audio. The QV Headset is vir- tually flat to 10kHz, while the QE Headset utilizes a midrange “presence” peak for optimum reproducti

FEATURES • Microphones are molded to high quality gooseneck booms constructed of brass over stainless steel wire with matt black polyurethane covering. Compliant molding reduces microphone handling noise, and the booms bend smoothly, hold their shape and are rated to withstand over a thousand 90° bends without degrading. • Both the QV and QE Headsets are moisture protected, and the QE is water resistant, making it the microphone of choice for aerobics instruction or in other high-humidity enviro

SAMSON SAMSON QE QV USING YOUR QE/QV HEADSET As shown in the illustrations below, the correct way to wear your QE/QV Headset is over the ears, as you would wear a pair of eyeglasses. The QE/QV Headset is specially designed to be used up close, so be sure to adjust the microphone to be directly in front of your lips, as shown in these illustra- tions. Although it generates significantly less handling noise than most other head- sets (due to its compliant molding), it should be left in one positio

USING YOUR QE/QV HEADSET Slide the foam windscreen over the microphone ,as shown in the illustration on the previous page, to eliminate wind noise. The PM4 phantom power adaptor with its special interface, enables a mixer to provide phantom power to condenser, piezo or electric microphones. The PM4 converts high impedance (50 k – 10meg ohm) to low impedance (600 ohms) allowing long cable runs without noise and gain loss. Connect the P3 plug from your QE/QV Headset into the locking input of the P

USING YOUR QE/QV HEADSET Every microphone has a characteristic polar pattern that determines how well it accepts or rejects signals coming from various areas around the microphone. A type of design which is particularly good at rejecting background noise is the bi-directional polar pattern uti- 0° lized by the QE Headset, as shown in the illustration on the -10dB left. -20dB 90° 270° QE Headset Polar Pattern (measured at 1 kHz) 180° 10

USING YOUR QE/QV HEADSET Omnidirectional mics accept all signals regardless of wherever those signals originate (in front of the mic, behind it, to the side, etc.). In contrast, directional cardioid mics are specifically designed to accept mostly signals coming from directly in front, and to reject 0° signals coming from behind or from the side. The most extreme variation of cardioid is -10dB the hypercardioid pattern uti- lized by the QV Headset (as -20dB shown in the illustration on the right)

dB (re 1 Volt/Pascal) USING YOUR QE/QV HEADSET In the QE Headset, three noise cancelling modes operate together to provide 20 - 30 dB of noise reduction: First, the small size of the mic capsule and the short distance between front and rear ports reduces the sensitivity at 1 kHz to far field noise by 15 dB compared to the close talking response. Secondly, as shown in the frequency response graph below, noise at lower frequencies is additionally attenuated. And, -55 -35 finally, the bi-directiona
