SAFETY PRECAUTIONS:
Never operate the 992 with the top panel removed. The top
panel’s perforations provide more then enough ventilation for cooling. The top panel also plays an
important role in maintaining good signal to noise ratio performance.
Always provide a source to ground (earth.) Never under any conditions should a power cord
that has the 3
rd
prong for ground missing or defeated be used.
Do not place the 992 in an area where there is a potential for fluids to fall, spill into or come in
contact with the 992. If you notice fluids or moisture present inside the 992
DO NOT
turn power
on! Although there are plenty of safety measures built into the unit for the protection of the user, it is
best if you contact LaChapell Audio for direction.
Hookup:
AC PEM: Double check the power setting on the power entry module (PEM) is correct. In the USA it should
always read 115v on the red voltage indicator located just above the rear power rocker switch. As stated above,
use only a 3 prong detachable AC power cord. See the SERVICE/REPAIR section for replacing the fuse(s).
International Power Settings
At this time power settings other than 115v are only available as a factory modification-
DO NOT
attempt to use the
red voltage fuse sub module for voltage adjustments. If this modification has been performed you will see the
corresponding check box marked on the rear panel accordingly. Contact LaChapell Audio if you have any questions.

XLR INPUT
: Located on the rear panel are the balanced Microphone XLR inputs. Pin orientation is
standard.
•
XLR OUTPUT:
Above the XLR inputs are the balanced XLR outputs. These outputs are to be
connected to your recording/broadcast console, recorder, or other device’s that can accommodate a
balanced line level signal (compressor, EQ, etc…)
•
Hi-Z INPUT:
Located on the front panel are the auto-switching Hi-Z instrument inputs. This Hi-
Z stage is placed in front of the balanced microphone input stage and utilizes a Cinemag JT-DBX
transformer for signal balancing.
