INTERACOUSTICS AC40 clinical audiometer (Reconditioned)

Power supply: 230 V,
Frequency: 50/60 Hz,
AC40 audiometer
is an advanced clinical audiometer with high-frequency audiometry capability,
It has pre-programmed and automated tests for ease of use presented on a large 10" LCD screen,
The device's menu in English,
Keypad on the control panel in English,
The AC40 comes standard with high-frequency audiometry, multi-frequency audiometry, MLD, built-in free field amplifier and more,
The AC40's two channels function independently, so much so that sounds of two different frequencies can be fed simultaneously from two channels,

125 - 16000Hz divided into two ranges: 125-8000Hz and 8-16kHz,
Frequency resolution:
Multi frequency. Programmable in 1, 1/2, 1/3, 1/6, 1/12, 1/24 octave increments,
Modulation:
Programmable partial frequencies:
5, 10, 25, 50 Hz,
Programmable intensity:
± 0, 0.2, 0.4, 0.6, 0.8, 1, 2, 3, 4, 5, 10, 15, 25% ,
Synchronous masking:
Couples channel 2 attenuator to channel 1 attenuator,
Attenuators:
Clickless, -10 to 120 dB HL in 1dB or 5dB increments,
Tone switches:
Silent switches on control panel or remote tone switch,
Test types:
Tonal:
Manual, continuous, single or multiple pulses,
