Console Session Management

Console 1 to Console 2 Session

If a Console session was created and saved with Console 1 and the session is subse-

quently opened with a multi-unit Thunderbolt setup in Console 2 (UAD v8.0.1 or later),

the previous Console 1 conﬁguration is retained, with the exception noted below.

Note: Cue and headphone management settings are handled differently in Console

2 sessions. These settings are not retained when updating a Console 1 session.

Single-to-Multi Session

If a Console session was created and saved with a single-unit setup and the session is

subsequently opened with a multi-unit setup, the expander unit(s) is automatically added

to the session and the number of Console inputs expands accordingly. All settings from

the single-unit session are maintained.

Multi-to-Single Session

If a Console session was created and saved with a multi-unit setup and the session is

subsequently opened with a single-unit setup, the expander unit(s) settings are retained

in the session for ofﬂine conﬁguration. The expander unit(s) can be removed from the

session via the if desired.

Multi-Unit Constraints

Certain features are reduced when multi-unit cascading due to technical constraints re-

quired to maintain integrated mix buses with Realtime UAD Processing capabilities.

All multi-unit constraints are listed below.

• Multi-unit cascading is unavailable at sample rates of 176.4 kHz or

192 kHz.

• Cue buses can be routed to the line and/or digital outputs of the monitor unit only.

This constraint does not apply when routing cues to headphone outputs.

• Flex Routing destinations can be only be assigned to outputs on the same unit as

the input. It’s not possible to cross-route from one unit to another.

• Apollo uses Thunderbolt for inter-unit clocking when multiple Apollo devices are

connected. Because the host computer is the master Thunderbolt controller, inter-

unit clocking, and therefore standalone use, is not possible with Apollo multi-unit

cascading.

• Connecting two Apollo Twin units is not a compatible conﬁguration.
