Default Expansion Chassis VS 64 Bit Chassis Latency

Does the new Expansion Chassis HD on PCIe sys have more/less/same latency as a Digidesign/Magma 64 Bit Chassis?

Hi there,
Systems using the Digidesign Expansion|HD will incur slightly increased RTAS real time monitoring latency compared to systems using the Digidesign 64-bit chassis. *The increased RTAS monitoring latency is due to the hardware buffering needed for the Digidesign Expansion|HD. For example, a HW Buffer setting of 128 samples on a Digidesign Expansion|HD system achieves the same RTAS monitoring latency as a setting of 256 samples on a system using the 64-bit chassis. The RTAS monitoring latency can be adjusted by decreasing the HW Buffer setting as follows. Please note this is not an issue when playing back existing audio, as the Pro Tools delay compensation engine will compensate for the latency.

Hope this helps,
Kevin Miller
Expansion|HD Product Manager
