31. rrect frequency range for its driver The amplifiers are designed specifically for these speaker load impedances There is no guesswork as to what load each amplifier has to drive so they can provide maximum acoustic output from the speakers yet minimize the danger of speaker damage due to overdriving a lesser amplifier The connecting wires between the amplifier outputs and the drivers are kept to a minimum so the damping factor of the amplifier isn t compromised by the resistance of long speaker cables In addition all the power from the amplifier is transferred directly to the drivers with no speaker cable losses e The acoustic sum of the outputs from the two drivers is optimized electronically as well as physically so the amplitude response is flat and there is no lobing error The presence of active circuits within the speaker cabinet allow the designer to add on extra details such as a high quality mic line input section and optional accessory modules In short all the complex interconnected components in the system are designed to work in harmony with each other to produce the best possible sound e HOOKUP DIAGRAMS Quick Start 1 23 2 Start with the following settings on the back of the SRM350v2 Turn the POWER switch off down Set the CONTOUR and MIC LINE switches out If using a microphone as the input to the SRM350v2 push the MIC LIN
