AVT1023 A

Despite the rapid development of digital audio technology, 'black' gramophone records enjoy unflagging popularity among audiophiles. To listen to them you need a turntable with a MM insert (with a movable magnet) equipped with an amplifier with RIAA characteristics. The kit uses a modern, double operational amplifier type TDA2320. Its characteristic feature is the low-noise input stage, full frequency compensation, high gain and close to 100 dB channel separation. Elements in the negative feedback loop shape the characteristics of the amplifier according to the RIAA standard.

The device is especially recommended to all audiophiles using analog turntables as a signal source

Selected parameters:

• two-channel, stereo system
• gain k = 38 dB (f = 1kHz)
• input voltage (maximum) 55 mV
• signal / noise ratio> 78 dB
• nonlinear distortions <0.08% (in the whole band)
• power supply - 15 V
• printed circuit board and documentation included
  A version with a set of components for self-assembly is available
