Apollo Software Manual Chapter 10: Multi-Unit Cascading 173

Multi-Unit Operation

Power On Sequence

With UAD version 8.0.2 and higher, Thunderbolt devices may be connected and/or dis-

connected when the computer and/or devices are powered on (hot plugging). The order in

which the Apollo units are connected and/or powered on is not critical. Apollo units are

automatically detected a few moments after connection.

Multi-Unit Monitoring

To facilitate the mix bus integration within Console, one unit must be designated as the

monitor (master) unit. All other units are expander (slave) units.

Monitor Unit Designation

The Apollo unit at the top of the in the Hardware panel within the Console Settings

window is the designated monitor unit. The monitor unit is indicated by a small orange

speaker icon next to its unit letter.

A different unit is designated as the monitor unit by dragging the unit to the top of the

Devices Column, as shown in the screenshots below. The monitor/expander designations

can be changed at any time.

Important: Changing the monitor unit designation changes the driver I/O conﬁgu-

ration. Quit all audio applications before performing this action. Additionally, wait

for this operation to complete before making further adjustments.

Multi-Unit Monitor Outputs

When multi-unit cascading, all units share the same monitor mix bus. The monitoring

speaker system (including ALT monitors, if conﬁgured) must be connected to the monitor

outputs of the monitor unit only.

Note: When changing the monitor unit designation, the monitor speakers must be

physically connected to the new monitor unit to hear the monitor outputs.
