Connector Wiring
The RoomMatch
®
array module is equipped with two (2) Neutrik
®
NL4 connectors wired in
parallel to allow loop-through connection to an additional module. The connector is wired to
provide separate amplifier channels to the high-frequency (HF) and low-frequency (LF) transduc-
ers as follows:

Optional Gain-Shading Kit Installation
An optional gain shading kit (RMSHADE) is available for RoomMatch™ modules to attenuate the
lower-3 compression drivers relative to the upper-3 drivers. This option may provide more
uniform coverage in array configurations with large changes in directivity index from module to
module. An electrical diagram for the mid/high compression drivers illustrating the gain shading
kit circuit is shown below.
