C.2 Installation
C.2.1 Cabinet
The DAA arrives from the factory already installed on its chassis. An NCM or HS-NCM can be
mounted on it. (Refer to Figure C.7). The DAA chassis mounts in a CAB-4 Series cabinet, as well
as in the EQCAB Series backboxes. It is compatible with CAB-3 Series cabinets per the
instructions on page 100.
Prior to installation,
• Review the installation precautions at the front of this manual.
• Installers should be familiar with the standards and codes specified in “Standards and Other
Documents” on page 9.
• Ensure all wiring will comply with national and local codes.
• Review the installation instructions in this section.
Locate the cabinet backbox on a surface that is in a clean, dry, vibration-free area. The top should
be located so that all operational buttons, switches, displays, etc. are easily accessible and/or
viewable to the operator - usually no more than 66 inches (1.7 m) above the floor. Allow sufficient
clearance around the cabinet for the door to swing freely, and for easy installation and maintenance
of equipment.
Follow the instructions below.
1. Mark and pre-drill two holes for the keyhole mounting bolts. Install bolts.

Jumper JP2 When DAAs are sharing batteries, cut this jumper for all but one of
the DAAs to disable Earth Fault detection. Only the DAA intended
to report Earth Faults should have this jumper intact.
Note that this jumper does not enable/disable Earth Fault detection
on the Digital Audio Ports. That function is determined by SW9 and
