This is a CD Transport as opposed to a standard CD player, meaning it does not have an onboard DAC. It is designed ideally to be used with either the PRE550 which has two CS4398 Cirrus Logic DACs or the IA350 which has one. The rear panel provides you with 5 different digital output options including I2S, AES, Coaxial, BNC and Optical . The front panel includes 4 YBA styled switches which control On/Standby, Stop/Play and Pause, Track forward or track back and finally a Sampling Rate selector. As with the Signature CD Player, this is a top loading device and operates in the same way. All Passion products have a display dimming feature on the remote control handset which allows you the option of several levels of brightness.
