Truly portable design

The new, ergonomical MA 49 has a rugged, integral carrying case with ample storage for all accessories. The soft, comfortable handle and light weight - 5,8 kg/12,8 lb. including accessories - makes transporting the instrument easy. And, it takes less than one minute to open the front cover, connect to power and start to operate. A desktop version without the carrying case is optional.

Easy to operate with ergonomic design The MA 49 is fast and easy to operate. The unique detented intensity level and frequency control knob can be operated from the top or side. Locating the interrupt/presentation bars adjacent to the intensity knob allows one handed control. Sensible keyboard layout with LED's for each function ensure error-free operation. The bright LED display shows frequency and intensity level settings.

Automatic data transfer to PC The MA 49 has a standard RS 232 serial interface to automatically transfer test results to a connected PC. A software driver for the NOAH Audiometry and Hearing Aid Fitting program is available.
