I N T RO D U C T I O N 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 aerobics use and high-humidity environments).
I N T RO D U C T I O N 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.
F E AT U R E S The Samson QE/QV Headset utilizes state-of-the-art headset microphone technology 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.
F E AT U R E S • 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.
U S I N G YO U R Q E / Q V H E A D S E T MS SA ON QV MIC SA MS ON QE MIC 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 illustrations.
U S I N G YO U R Q E / Q V H E A D S E T 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.
U S I N G YO U R Q E / Q V H E A D S E T 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 uti0° lized by the QE Headset, as shown in the illustration on the -10dB left.
U S I N G YO U R Q E / Q V H E A D S E T 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.
U S I N G YO U R Q E / Q V H E A D S E T dB (re 1 Volt/Pascal) dB (re 1 Volt/microbar) 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.
U S I N G YO U R Q E / Q V H E A D S E T dB (re 1 Volt/microbar) dB (re 1 Volt/Pascal) Because of their polar patterns, frequency response, and noise cancellation design, both the QV and QE Headsets excel in environments where there is a good deal of unwanted ambient sound—they deliver those sig-40 -60 0° nals originating directly in front of the mic capsule itself while -50 -70 rejecting those that originate from other directions.
