AVT1023 B

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
