The addition of Bluetooth to the Genesis range of products added a level of excitement to the legendary YBA hi-fi brand. Without too much trouble, a user can simply pair with whatever device may be preferred (phone, tablet etc.) and be listening to music in no time at all! The preamplifier offers so much more however …. the IA3A is equipped with one S/PDIF (75 ) COAXIAL digital input, USB (24/192KHz) as well as Bluetooth to receive digital signals from separate digital components. All digital inputs automatically adjust to any of the standard digital-audio datarates from 16/44.1 KHz to 24/192 KHz. There is one digital output plus a pre-out option to use a subwoofer, a separate power amplifier or active speakers. The preamplifier allows the connection of 2 RCA input sources, where the video input has a bypass option. There is also a balanced input. Should you wish, you can disconnect power to the digital section of your IA3A when using an analogue source. Remember to re-engage this switch when using any digital input.
