The wide-band distribution amplifier with RDS or SCA services summing control.<br>KOALA is a very versatile equipment, that can work both as MPX distributor and MPX splitter, the policy commutation can be managed as well.<br>KOALA is composed of two sections and for each section a double MPX-RDS input is available. It can be distributed, split locally or buffered output (sections MPX-1, MPX-2, MPX-3 and MPX-4).<br>There's no jumper settings inside Koala - the wide front panel input/output range allows the user to set any kind of commutation policy, distribution, Mpx re-run and Mpx split.<br>The commutation command can be managed by GPo command via optocoupler port installed in KOALA's rear panel.<br>KOALA has 4 input sections serving for the connection to the main signal as test and to be distributed.<br>One output is buffered, with level adjustment via trimmer, while the second output is not buffered and therefore passive, useful to directly control the injected signal at the input.<br>In addition, the buffered output is equipped with a bypass circuit Hardware essential in case of power failure.<br>The wide bandwidth of the inputs and outputs (100kHz) allows KOALA to distribute/split the MPX signals with or without RDS or SCA signals. In the event of power failure, a relay connects directly to the AUX 2 and AUX 3 respectively to the input signals and MPX1/MPX2 (hardware bypass). The presence of a power supply transformer-based directly integrated in KOALA, further simplifies the installation.
