AV14 Charge and IEPE Amplifier
The 1-channel charge amplifier AV 14 has been constructed mainly to monitor acoustic and vibration signals.
It has a measuring channel for an electret condenser microphone or a piezoelectric accelerometer.
The switching over from the accelerometer to the microphone comes automatically, when the microphone mini-jack is plugged in at the output socket you get a voltage proportional to the acceleration or sound pressure independent of the amplification of the headphone amplifier.
So the instrument can be used as a front end for analyzers or similar instruments.
Features

KH10 Dynamic Headphone
KH10 is a closed dynamic headphone and it is designed for critical music and sound monitoring in an open environment. The headphone features a frequency response of 5 Hz to 30 kHz and is equalized to the diffuse sound field. The single-sided 3 m connecting cable is equipped with an in-line volume control for optimum set-up. It is fitted with a gold-plated mini stereo plug (3.5 mm) with a 1/4″ (6.35 mm) adapter and is therefore suitable for use with almost all headphone amplifiers.
The rugged headband construction has been strengthened to give the headphone a very secure fit, matched with mechanical reliability. Soft ear pads that are easy to clean and adjustable, sliding earpieces ensure listening comfort during extended periods of use.
Features
- Closed diffuse field headphone
- Excellent ambient noise attenuation (better 35 dB A)
- Superb audio quality with high sound pressure level (105 dB)
- Robust spring steel headband
- Single sided cable (straight cable, 3 m long) with in-line volume control
- Gold plated jack plug (3.5 mm) and adapter (6.35 mm)
