The ChatterVox Pro personal voice amplification system is in actuality a small "Public Address System." With four microphone styles to choose from, the ChatterVox offers easy and comfortable solutions no matter what the application.ChatterVox personal PA system ChatterVox personal voice amplification systems may qualify for reimbursement under Medicare or personal medical insurance: Product code L8510. Download a copy of Health Insurance Claim Form OWCP-1500. Centrum Sound does not handle insurance claims.

The Classic ChatterVox Pro Model 100 amplifier has 5 watts of power and can boost vocal output by as much as 15 dB. The unique ChatterVox fanny-pack design amplifier weighs only 1.1 lb. and a simple volume control with built-in On/Off switch and Power-On LEDChatterVox Pro 1000 belt strap amplifier indicator constitutes the only user control. The ChatterVox Pro is powered by six environmentally friendly, high capacity Nickel Metal-Hydrate rechargeable AA size batteries. It can operate for more than 14 hours of continuous use on a single overnight charge. The standard system includes a 110 volt charger but an international charger with all known plug types is also available. In case the unit was not properly charged, the ChatterVox can also operate on six (6) regular AA size Alkaline batteries. We recommend the ChatterVox be supplied with the optional black textured neoprene "fanny-pack" cover. An black smooth leatherette cover is also available.

ChatterVox Pro includes choice of four microphone styles. All microphones are equipped with a 3.5 mm mono-plug. Lapel microphones are not available for ChatterVox systems.

The HM-100 multi-purpose headset microphone is built to take the demands presented by the most rigorous applications. At the same time it is lightweight, comfortable and easy to use. The head wire is rubber-coated for strength. It can be readily reformed to fit any head size or shape. The HM-100 is perfect for applications that require close miking to achieve maximum gain before feedback. It should be first choice for most common speech applications.

The HM-150 heavy-duty headset microphone is the innovative solution for tour guides, auctioneers and performers who by nature raise their voice above normal speech level. With a short boom it offers optimum sound pickup at the side of mouth position thus reducing breath and pop noise. It is designed with a sweat-proof mic element which provides long hours of active use. The HM-150 should not be used by people with speech impairment.

The MM-100 handheld pencil microphone is suitable for interactive applications and for people whose physical condition otherwise prevents them from wearing a headset microphone. The unidirectional back electret condenser microphone offers excellent sound reproduction and is the best choice for applications where an unobtrusive microphone is needed. It is supplied with a lavaliere cord for convenient hanging the microphone on the chest.

While the CM-200 collar microphone may offer greater wearing comfort, it is only recommended for applications where head movements can be restricted as optimum performance is only achieved when mouth is a few inches away from the mic head. Sideways, upwards or downwards head movement will cause the speakers voice to fade in and out. However, if mastered properly, its acoustic features and compact design is ideal for demonstration instructors, lecturers and others who cannot wear a headset microphone but do require high quality vocal pickup in a hands-free application.
