Apollo Software Manual Chapter 7: Multi-Unit Cascading 109
Constraints
Certain features and/or I/O streams are reduced when multi-unit cascading due to limited
audio bandwidth or technical constraints required to maintain integrated mix buses with
Realtime UAD Processing capabilities. These constraints are listed below.
Auxiliary 2 (Apollo only)
• Aux bus 2 is unavailable when multi-unit cascading with Apollo.
High Sample Rates
176.4 kHz and 192 kHz
• Multi-unit cascading is unavailable at sample rates of 176.4 kHz or
192 kHz.
88.2 kHz and 96 kHz (Apollo only)
• Both ADAT ports must be used for S/MUX connections when multi-unit cascading
at sample rates of 88.2 kHz or 96 kHz.
PT Mode
• Avid Pro Tools allows 32 channels of I/O with non-Avid branded audio interfaces.
Because audio streams exceed this count when multi-unit cascading, some Apollo
I/O channels are unavailable in PT Mode when multi-unit cascading.
The specific Apollo channel numbers and names that are available when PT Mode
is active are listed in the
“Driver I/O Tables” on page 118 .
Combining Different Apollo Models
• Combining Apollo with Apollo 16 is an unsupported configuration.
• Apollo Twin cannot be used with multi-unit cascading.
