ACO64 Hardware Setup
The ACO64 commutator is analogous to the ACO32 and also typically mounted above the
subject. A PZ preampli
fi er is connected to the DB26 connectors marked A, B, C, and D on the
face of the commutator. A headstage (with splice connector) and a splice-to-splice adapter are
connected to the interface receptacles on the connector module. See
Headstage Connections
below for more information on this connection.
See ACO64 Dimensions for mounting dimensions.
The motor in the ACO32 commutator is attached to a plate designed to allow it to be disengaged for testing and
troubleshooting noise issues. The plate may slide out of normal position during shipping or anytime the
commutator is turned upside down.
If the motor is not engaged, you can turn the bottom section of the rotating shaft, but the rest of the shaft does
not follow.
To reengage the motor:
Hold the commutator with the faceplate up.
Grip one side of the commutator.
Bring the commutator down to thump the bottom corner with the heel of your palm, as shown below.

The motor in the ACO64 commutator does not disengage like the ACO32. The ACO64 has an additional hardware
mount on the bottom, below the headstage receptacles, facing the subject.
