462dsp/AM audio processor

This is an advanced unit for AM transmitters that offers:

One balanced stereo output (20 Hz - 15 KHz) for Internet streaming or Hi-Fi recordings

Two independent balanced analogical outputs for A.M. transmission

A.M. TX outputs has NRSC1 equalization and low-pass cutoff filter, commutable between 7 kHz & 5 kHz. Both A.M. outputs allow asymmetric modulation to increase the power and coberture of the emissions. While the negative modulation keeps always at 100%, the positive one can vary digitally between 100% and 150%, controllable from LCD screen. The advanced asymmetric clipping system with double stage of Log clipping, an invention of Solidyne, allows to increase to the transmitted power.

The 462dsp/AM fulfills standard NRSC-2 of spurious irradiation in A.M.



462dsp/AM/AES; for DIGITAL AM transmissions


This model is oriented to the transmission of digital AM in simulcast using IBOC or DRM technology. 462dsp/AM/AES has digital AES-3 input / outputs for direct connection to the digital transmitter, with a bandwidth of 15 KHz in stereo, and simultaneous analog outputs for conventional "in band" transmission
