The 5045 Primary Source Enhancer is a two channel device that is exceptionally useful at reducing feedback, effectively increasing the level a microphone can be raised before feedback occurs in a live sound environment by up to 20dB, without negatively impacting the sonic integrity of the source signal. With controls that are very simply laid out and generally require minimal adjustment, the 5045 is an invaluable tool for churches, stadiums, performance halls, or any venue where feedback is problematic. The 5045 shares some traits with conventional noise gates , but operates with a different principle. One common aspect is that both reduce the gain during the absence of signal or more specifically, both begin to attenuate when the level of a signal falls below a certain user-defined threshold. The 5045 senses when someone is speaking or singing into the mic and allows the signal to pass through, and senses when the person has stopped talking or singing and reduces the gain appropriately, which helps reduce the tendency of a system to feed back. Most importantly, the 5045 does not require filtering and digital processing to achieve significant benefits. Simple Setup Instructions Operation of the 5045 is extremely simple. The 5045 accepts line level signals, such as the output of a microphone preamplifier or the Insert send of a console. The 5045 outputs are also line level, and typically feed a console line input or Insert return. Because the 5045 uses transformer-coupled inputs and outputs, it connects easily to virtually any combination of balanced or unbalanced inputs and outputs, provided you have commonly available appropriate adapters. Once the 5045 is connected and power has been turned on, the next steps are relatively simple. A good safe initial starting point is: PROCESS ENGAGE not pressed, TIME CONSTANT set to C or D, RMS/PEAK button not pressed (RMS mode), THRESHOLD fully counterclockwise (or -18), and the DEPTH also fully counterclockwise. Now, have someone speak or sing into the microphone and press the PROCESS ENGAGE button; if the 5045 is connected properly, there should be no change in level. As the person is talking or singing, adjust the THRESHOLD so that the green PROCESS ACTIVE LED glows solidly when they talk and dims when they stop speaking (between sentences, for example). Gently increase the DEPTH knob to about -10 dB as a starting point. If the sound system was previously on the edge of feeding back, the above procedure should have helped. If the system volume was set low to play it safe and well under the feedback zone, you can try increasing the volume of the channel slowly and adjusting the DEPTH to achieve more volume before feedback sets in. The 5045 will not completely eliminate the chance of feedback (given enough volume, it s always possible), but it is generally effective at allowing both increased levels along with less chance of annoying feedback. Everything else being equal, typically louder voices (or hotter signal levels) will be associated with more clockwise THRESHOLD settings, and quieter voices may require more counterclockwise rotation. In either case, the key thing to watch is the PROCESS ACTIVE LED that should always be lit when the person is talking or singing: the LED should only dim after they stop vocalizing. Adjust the THRESHOLD accordingly.
