Hardware Setup
Select a Suitable Location
•  Locate Apollo Twin MkII on a flat surface so its feet will maintain airflow beneath the 
unit.
•  The location should be sturdy enough to securely hold its weight and withstand 
the pressure of operating the top panel controls.
•  Leave enough room behind the unit for connected cabling. 
•  Do not block the cooling vents on the bottom or sides of the unit.
Connect to Computer and Power
Caution: Before powering Apollo Twin MkII on or off, lower the volume of the 
monitor speakers (if connected) and remove headphones from your ears.
1.  Connect one Thunderbolt cable (not included) between Apollo Twin MkII and the 
host computer.
2.  Connect the included power supply to an AC outlet (Apollo Twin MkII cannot be 
bus powered).
3.  Connect the locking power supply to the rear panel of Apollo. Align the two tabs 
on the power cable's connector to the notches on the input, then rotate the barrel 
to prevent accidental disconnection.
Important: After ensuring the locking barrel tabs are aligned with the chassis slots 
and the barrel is fully inserted, rotate the barrel to secure the connector.
4.  Apply power to Apollo Twin MkII using the rear panel's power switch. Apollo Twin 
MkII is now ready for Software Setup.
