AVT2392 A

It is a universal preamplifier of all variable signals with frequencies of 20Hz ... 100kHz. First of all, it will be used as a microphone preamplifier.
The system can work with microphones:

• dynamic
• electret two-ring
• electret three-terminal
• capacitive.

The use of miniature elements means that the system assembled on a tiny board can be built into virtually any audio device or become part of any new construction.

Recommendations : The device is especially recommended for electro-acousticians, musicians and constructors of audio equipment.

Basic parameters:

• low noise
• adjustable gain in the range 1x ... 80x
• great input resistance, above 1Mom
• output resistance below 1
• single voltage supply 6 ... 15V
• power consumption below 5mA
• PCB dimensions 37x21mm
• in the set two printed circuit boards and documentation.
  A version with a set of components for self-assembly is available
