Module Installation
The module installation procedure is the reverse of the
removal procedure described above.
Rear Panel Input Units
First pass the wiring through the opening in the rear
panel and pull it through to the open module area. Then
attach the rear-panel unit with two screws.
Top-panel Modules
When an input module is being installed it is first
necessary to connect the wiring from the corresponding
rear-panel input unit to the connectors on the module and
secure the wire bundle in the wiring harness.
When inserting the module into the console make sure
that the connectors on the bottom of the module are
aligned with the corresponding connectors on console
frame. Input modules have two connectors (see the
illustration below), while master modules have three.
Guide pins are provided to make alignment easy – as
long as the guide pins are properly inserted into the
corresponding holes on the bottom of the module frame
alignment should be almost automatic. Insert the module
firmly until its panel is flush with the console top, but
avoid using excessive force.
Finally, secure the module with the two screws.
Input Transformer Installation
The PM5000 input modules feature electronically
balanced inputs that do not normally require any
additional isolation. If you would rather have
conventional transformer-isolated balanced inputs,
optional ITR5000 input transformers can be installed.
The number and location of input transformers is
different for mono and stereo input modules. The
installation procedure is outlined below.
●
Transformer Installation On Input modules
1
Turn the console’s power supply OFF.
2
Remove the mono or stereo console on which the
transformer(s) is to be installed as per the module-
removal instructions above.
3
Attach the transformer to the mounting bracket
supplied with the ITR5000 transformer kit with the
nut as shown in the illustration. Make sure that the
transformer leads are positioned in relation to the
mounting bracket as shown in the illustration (the
transformer leads must not be clamped between the
transformer and mounting bracket).
4
Attach the transformer to the bottom stay of the
module. Align the screw holes in the transformer
mounting bracket with the screw holes just in front of
(toward the fader end of the module) the square hole
through provided for the transformer leads as shown
in the illustration below, and secure with the two
small M3 screws. On mono modules the transformer
should face toward the front (fader) end of the
module, and on stereo modules the second
transformer should be mounted on the other side of
the square lead hole, facing in the other direction so
that the lead hole is not obstructed.
NOTE
When a module and/or rear-panel unit has been sent out for repair
and the module slot is likely to be empty for a while, it is a good
idea to install the blank module panels (BLM5000) to prevent
objects from falling into the console and potentially causing
damage. The BLM5000 blank module option includes blank
panels for both the top-panel and rear-panel.

NOTE
The input impedance will change when the transformers are
installed: electronically balanced input impedance = 3 k
Ω
,
transformer input impedance = 1 k
Ω
.
Do not clamp the transformer leads when mounting
