No user serviceable parts inside; refer servicing to qualified personnel. WARNING: To reduce the risk of fire or electric shock, do not expose this appliance to rain or moisture. This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosurevoltage that may be sufficient to constitute a risk of shock. This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. [. . . ] The MULTICOM PRO converts two channels to stereo mode by engaging one of the COUPLE switches, where the left of the channels assumes the control of both audio channels, i. e. By pressing the COUPLE switch, you override all the controls and switches of channel 2 (or 4) with the exception of the IN/OUT and SC Filter switches as well as the peak limiters THRESHOLD control. The controls of channel 1 (or 3) take over all functions of channel 2 (or 4). 9 + 10 11 14 4.

Please make sure that your local voltage matches the voltage indicated on the unit, before you attempt to connect and operate the MULTICOM PRO. Blown fuses may only be replaced by fuses of the same type and rating. These are the audio inputs of your MULTICOM PRO, available both as balanced 1/4" jack and XLR connectors. With the OPERATING LEVEL switch you can adapt the MULTICOM PRO to various operating levels, i. e. you can select both the -10 dBV home recording level and the professional studio level of +4 dBu. The level meters are referenced automatically to the selected level, i. e. an optimum operating range of the meters will always be ensured. 13 14 15 16 4. APPLICATIONS In this section, several typical applications of the BEHRINGER MULTICOM PRO are discussed. Please take the time to study the application examples carefully, in order to be able to make full use of the MULTICOM PROs capabilities in the future. Main Applications And Initial Settings The main applications of the BEHRINGER MULTICOM PRO can be divided into two categories: The compressor section is used to compress the program material and to create special effects and unusual sounds, which are used for recording and musical performance. The subsequent Peak Limiter section is designed to protect loudspeakers, tape recorders, transmitters etc. from being overloaded. 5. 1 Compression/Leveling/Limiting/Clipping Now that the functions of the individual sections have been clearly explained, we would like to acquaint you with more terms and relationships of the dynamics process. Compression A compressor converts a large dynamic level into a restricted range. The extent of the resulting dynamic level is dependent on the threshold, attack, release and ratio settings. As it is the desired effect of a compressor to increase a low level signal, generally the threshold is set low. The inaudible compression mode requires fast attack and release times and low ratios. The faster the chosen control times and the higher the compression ratio, the greater the effect on the short term dynamics.
