CX335 User Manual v1.0

With this setting, lower level signals will pass through the
compressor unprocessed, but any signal exceeding the
threshold will produce a definite maximum output level that
will never be exceeded (the gain reduction meter will confirm
compressor action). The LIMIT LED should never illuminate
if PEAK is set correctly (turn it up if the LED does illuminate).
Fitting the tamper-proof cover
The CX335 is supplied with a front panel security cover
kit which, when fitted, prevents unauthorised tampering of
the controls. After the CX335 has been installed, connected
and satisfactorily adjusted, we recommend that the security
cover is fitted.
To fit the cover, proceed as follows:
1. Remove the two M4 hex-head screws at the left-hand
end of the front panel using a 2.5 mm AF hex key (not
supplied).
2. Fit one of the brackets to the front panel (note the
small rectangular cutout faces the centre of the unit),
using the two screws just removed.
3. Repeat Steps 1 & 2 at the right-hand end of the front
panel.
4. Insert the two M3 hex pillars through the brackets’
centre holes into the tapped holes in the front panel
and tighten with a nut driver.
5. Fit the security cover over the brackets, and secure it
in place with the two M3 x 6 hex-head screws supplied.
The four small holes in the upper and lower flanges of
the cover should align with the holes in the upper and
lower flanges of the brackets.
6. Insert the pointed ends of the “Plaseal” security tags
through the holes in the upper cover flange, threading
them through the holes in the lower flange as well.
7. The security tags work in the same manner as ordinary
cable ties. Providing you are absolutely confident with
the CX335’s adjustments (!), push the ends firmly into
the mating locks until you feel two consecutive clicks.
The security cover cannot now be removed without the
tags being cut first. [Hint for installers - do not leave any
spare tags on-site].
Preventing rear access
There is little point fixing the security cover as described
above if the rear panel of the unit is readily accessible, as
this allows the possibility of the unit being bypassed by
unauthorised persons, by simply removing the rear XLR
connectors and plugging them together.
We recommend therefore, that the CX335 is always fitted
into a 19” equipment rack which has a lockable rear door,
and side panels which are either also lockable, or non-
removable.
