7 SONIC EXCITER SX3040 User Manual 3.2.5 Stage operation with instrument amplifiers 3.3 Basic operation Besides being ideal for use with stereo signals, the SONIC EXCITER is also suitable for use with one or two individual signals, e. g. guitars. With electric guitars it can be used in combination with a combo amp or a separate modelling processoramplifier combination to give the guitar sound more presence, fullness and punch. A similar combination with a keyboard and an external amplifier is possible. Because the two channels of the SX3040 work independently, even two different mono signals can be processed. Connect the SX3040 to the effects loop connections on your combo amplifier. Determine whether the effects loop connections on your amplifier work in series in Insert mode or in parallel in Aux Send mode. Then set the MIX controls accordingly (see sections 3.2.1 and 3.2.2). If in doubt, refer to the instruction manual for your amplifier. If you are using a modelling processor, you must connect the processor output to the SX3040 input and route the SX3040 signal to the amplifier. Due to the small number of SX3040 controls, this is an easy processor to operate. Perform the following steps: 1) Connect the unit according to the application as described in section 3.2. ◊ First make the following settings for one channel (channel 1 or 2 depending on input assignment). For stereo applications choose the same settings for the second channel. 2) Switch on all devices (amplifier and loudspeaker last) and ensure that the IN/OUT switch (7) on the SX3040 is illuminated, i.e. that the unit is working and all controls are set to "MIN". For series connection set the MIX controls to the middle positions; for parallel connection set them to "MAX" (see sections 3.2.1 and 3.2.2). 3) Turn the DRIVE control (1) until the desired bass saturation effect is achieved and the green LED regularly lights up when peak levels occur. 4) Turn the TUNE control (2) to specify the frequency range for processing. 5) Turn the HARMONICS control (5) until the desired enhancement effect in the high-frequency range is achieved. 6) Turn the TUNE control (4) to specify the frequency range for processing. 7) To compare the original and processed signals, repeatedly press the IN/OUT button. Then adjust the dry/wet balance as desired. 8) Repeat steps 3) to 7) until you are satisfied with the result.

Installation 4.1 Rack mounting The BEHRINGER SONIC EXCITER SX3040 requires 1 U of height for installation in a 19-inch rack. Please make sure that you leave around 10 cm for the rear connections. For installation of the unit in a rack please use M6 machine screws and nuts. 4.2 Audio connections There are various ways to integrate the SX3040 into your setup. Depending on the application you will need different connecting cables, and these will be discussed in the following section. BXL3000A Fig. 3.3: The SX3040 in use with guitar amplifiers
