Lectrosonics LE Series - Manual (Page 7)

INSTALLATION
SYSTEM INSTALLATION - The LE8 module, like any other equalization module, will normally be driven from either
the AC1 Main Output, or from an EQN1 (if there is one in the system). The output signal from the LE8 should be
routed to a DP1 (if there is one in the system), an XO2 or XO3 (if there is one in the system), or to the system
power amplifier input.
MECHANICAL INSTALLATION
Prior to installing the LE8 module into the mainframe, the position of the LINK mode jumper must be set. See the
illustration below. The default setting is the jumper set on pins 2 & 3 for a single LE8 installed in the system. If
you plan to link two or more LE8 modules then the jumper should be moved to pins 1 & 2.
The LE8 module is installed from the rear of the Modular Audio Processor mainframe. The printed circuit board fits
into one of the ten sets of card guides provided in the mainframe. The module is then slid forward in the
mainframe until the female connector on the board is firmly seated on the male pins of the bus board. Care should
be taken when inserting the female connector onto the pins to be sure there is correct alignment. Four #4 machine
screws are provided to fasten the rear panel to the top and bottom rear rails of the Modular Audio Processor
mainframe. In addition, four #4 countersink machine screws are provided to secure the cover panel also provided,
to the front of the mainframe after system adjustment is complete.
ELECTRICAL INSTALLATION
Electrical interconnection from other Modular Audio Processor modules (or other equipment) to the LE8 is
straightforward. When connecting to other Modular Audio Processor modules (or other balanced in/out equipment),
simply use standard shielded XLR cables. When connecting to unbalanced equipment, see page 5 (Rear Panel
Description) for instructions on proper wiring. The Thru output may be used if a non-equalized signal is desired. If
more than one LE8 is in use, connect the Link Out of the first LE8 to the Link In of the next LE8. Then connect the
Link Out of that LE8 to the Link In of the next LE8, and so on. See the illustration on page 7.
Logic input connections are also straightforward. Connect the one of the Logic Out "+" terminals of an AP4 or EP4
module to one of the Logic In "+" terminals of the LE8. Repeat for the Logic Out "-" and Logic In "-" terminals. As
you assign each microphone in the system to one of the LE8 inputs, note that the Logic Inputs of the LE8 operate
in a priority ranking manner, with Logic Input 8 being the highest priority. This means that in the case of two or
more simultaneously active microphones, the LE8 will load the filters for the highest number microphone.
