5. Check the loudspeaker output wiring (see below). If necessary
change the output wiring to suit the new module configuration.
6. Reconnect the safety earth (ground) straps and refit the top and
bottom covers (6 x M3 screws per panel).
Ensure that the safety earth (ground) straps to both covers are
reconnected. With loose connectors not only is the mainframe
housing incorrectly grounded, there is also a risk of a short circuit
inside the device.
Loudspeaker output configuration
The loudspeaker output connectors are linked to the mainframe
power amplifier outputs by 4 pin push on connectors located
behind the mainframe loudspeaker connector panel. To reconfigure
the speaker output wiring the speaker connector panel needs to be
removed. To gain better access to the speaker output board the
input signal connector panel can also to be removed (6 x M3
screws in total).
Rear panels with speaker connectors using 4 pins (SPEAKON or EP-
5) are terminated with two 4 pin push-on connectors. Pressing the
sides of the push-on connectors unlatches and releases them from
the speaker output board terminals. There are three terminals for
each output connector (SUB/TOP/MlX - OUT A and MlX/SUB/TOP
- OUT B).
Depending on the choice of controller modules fitted to the
mainframe the appropriate terminals are used for the A and B
output connector wiring. In the block diagrams in section 2.9. the
connector positions appear on the right hand side. Both connectors
must go to a terminal of the same type (TOP-TOP, SUB-SUB or
MIX-MIX). Note the different arrangement of the sockets for OUT
A and OUT B on the connector board.
With ampMAX modules the outputs are connected to the MIX
terminals.
XLR speaker output panels have only one 4-pin connector. It is
wired to either of the MIX terminals - OUT A or B .
