The multi-channel receivers VSX-832, VSX-932, VSX-LX302, as well as the stereo receiver SX-N30AE, come standard with an RDS tuner for FM. If you want to use DAB digital radio, you can easily and affordably upgrade with the AS-DB100. The AS-DB100 simply plugs into the rear USB port of the mentioned Pioneer models and automatically integrates into the input selection and user interface of the devices. Therefore, the operation of the DAB upgrade is in no way different from that of a built-in receiver, and the signal quality is not compromised thanks to digital audio transmission and conversion with the high-quality DACs of the receiver. You can choose DAB at any time after purchasing the receiver – the noise-free and interference-free digital radio is always just two steps away.
