• Palm-size, and only 10 ounces.
• Battery operated - no awkward power cord.
• Soft carrying case with shoulder strap.
• Surface mount circuitry on four layer PC board.

CONVENIENT

• Headset is permanently attached - no lost or mismatched headphones.
• Modifications to the testing format are performed from the keypad.
• Digital calibration from the keypad - no need to open the instrument.

DURABLE

• Long life, touch sensitive, sealed keypad.
• Frequencies are quartz crystal controlled - never need adjustment.
• Accurate and dependable solid state switching.

FLEXIBLE

• Test the way you want as your testing needs change.
• Select frequencies and levels you want - skip the rest.
• Select pulsed, continuous, or warble tones.
• "Automatic sequencing™" enables users to screen their hearing by visually observing the front panel LEDs while listening for accompanying tones. May be used as a pre-test conditioning tool.
• Choose different parameters for manual testing and "automatic sequencing."
• Enter your settings from the keypad and they are permanently stored in EEPROM memory (even when power is off) until you want to change the personality of the DSP.

CD QUALITY

• Comparing the DSP Audiometer with most others on the market is like comparing a phonograph record to a compact disc.Digital precision guarantees frequency and level accuracy, low distortion, and ultimate perfection in the presentation of pulsed, continuous, or warble tones.

BATTERIES

• The DSP circuitry was designed to continuously monitor battery status. It idles between each key press and automatically shuts off after a few moments of inactivity (you choose how long).
• Batteries provide 30 hours of continuous tone presentations or months of normal use.
• Uses 4AA Alkaline batteries, available anywhere.
