Buspower compatibility meets flexible Analog I/O Performance

For the main inputs RME uses the proven mic/line preamps in XLR combo configuration of the Babyface Pro FS. Two digitally controlled preamps provide individually switchable 48V phantom power. These circuits feature a gain range of 75 dB, adjustable in steps of 1 dB, including a relay-driven PAD, resulting in exceptional EIN (Equivalent Input Noise) performance as well as line overload protection, and enough gain for even the lowest level microphones.

On the back of the Digiface AES there are 2 balanced analog outputs via XLR male to drive power amps, active monitor speakers, or recordings. The headphone output allows additional and independent high quality monitoring, providing sufficient output power and volume on high and low impedance headphones.
