Multi-Unit Wiring Diagrams
Note: For maximum signal integrity, short cables (e.g., one to three feet in length) are
recommended for all inter-unit connections in all multi-unit setups.
Multi-Unit Wiring (Apollo)
FireWire 800 Host Connection
Cables Required:
• One FireWire 800 cable for connecting to the host computer
• One FireWire 800 Cable for connecting between the two interfaces
• One ADAT optical cable for connecting between the two interfaces*
* At sample rates of 88.2 kHz and 96 kHz, two ADAT optical cables are required
Key points for this setup:
• The lower Apollo is designated as the Monitor (master) unit
• The upper Apollo is designated the as the Expander (slave) unit
• The Monitor unit is connected to the host computer via FireWire 800
(either Apollo FireWire 800 port can be used for this connection)
• The Expander unit is not connected to the host computer
• One FireWire 800 cable must be connected between the Expander and Monitor units
(either Apollo FireWire 800 port can be used for this connection)
• One ADAT optical cable must be connected from the ADAT OUT (1) of the
Expander unit to the ADAT IN (1) of the Monitor unit*
* At sample rates of 88.2 kHz and 96 kHz, a second ADAT optical must also be connected from
the ADAT OUT (2) of the Expander unit to the ADAT IN (2) of the Monitor unit
• Monitor, headphone, and auxiliary outputs are connected to the Monitor unit only
• Power on the monitor unit before the expander unit
