[. . . ] B1220DSP User manual V01 2007-07 EUROLIVE EUROLIVE B1220DSP Important safety instructions 1) Read these instructions. 5) Do not use this apparatus near water. Caution: To reduce the risk of electric shock, do not remove the top cover (or the rear section). No user serviceable parts inside; refer servicing to qualified personnel. [. . . ] (12) A noise-gate allows you to eliminate unwanted noise during signal pauses. This is done by a circuit that mutes the output when the signal level drops below a preset threshold. Use the NOISE GATE control to determine the threshold below which the noise-gate closes. (13) The TH LED lights up as soon as the signal level drops below the threshold value adjusted with the NOISE GATE control (12) (the noise-gate closes). To avoid feedback, it is recommended that you carefully select and direct the microphones used. Basically, you should use microphones with a high directivity, i. e. with a cardioid or hypercardioid polar pattern. Never hold a microphone so that its main pick-up area points directly towards the loudspeaker. When you hold it with its less sensitive side towards the speaker box, you can move closer to the speaker. + If you encounter persistent feedback problems, consider using our proven FEEDBACK DESTROYER PRO FBQ2496 for line-level signals. For signals with line or microphone level, we recommend our BEHRINGER SHARK DSP110. 4. Application examples 4. 1 Presentations With just one B1220DSP and one or two dynamic microphones, you can set up a basic audio system with very little effort. Thanks to the built-in mixer section, you can connect the microphones directly to the B1220DSP. Mount the B1220DSP on a speaker stand for optimum presentation and intelligibility of announcements. If one B1220DSP is not enough, you can, of course, use a second or even more loudspeakers. Connecting microphones: = Turn the LEVEL controls ( 3 ) fully to the left. = Connect your microphones to the MIC/LINE inputs. = Turn the LEVEL controls ( 3 ) gradually clockwise to set the volume of your choice. Observe the CLIP LEDs while adusting the volume. Make sure they never shine constantly but only light up at peak levels. = Use the LINE OUT connector ( 6 ) to connect an (optional) second B1220DSP. + Never place a microphone directly in front of the loudspeaker owing to danger of feedback!
