Diferencia entre Fireface 400 y Fireface UC (aparte del USB)

The secret of success: RME is the only manufacturer not to use a third party USB audio technology, but an own, self-developed Hammerfall Audio Core with an outstanding performance and uncompromised pro audio features.

Based on a newly developed RME Hammerfall core the Fireface UC provides revolutionary ultra-low latencies even with multiple channels. It uses two different firmware versions with different transfer methods to remove current restrictions of typical USB audio interfaces.

Under both Operating Systems the available latencies are simply sensational. The smallest buffer offered under Windows has 48 samples, under Mac OS X 14 samples. With this RME provides a performance previously not available from USB audio interfaces

With the Fireface UC, RME consistently set forth the path that was begun with the Fireface series. While the FireWire units (Fireface 400 and 800) still used a dedicated FireWire chip, the UC additionally integrates the entire USB protocol inside the FPGA and its programmable firmware, making the unit fully controllable and adjustable to new situations.
