[. . . ] NMP200 Noise Masking Processor Operation Manual ® Biamp Systems, 10074 S. W. Arctic Drive, Beaverton, Oregon 97005 U. S. A. (503) 641-7287 http://www. biamp. com blank print update Aug 8/01 Q: What is this 'Leveler' inside the NMP200? The Leveler function, in the Gain Manager section of an NMP200, is an automatic gain control (AGC). This means that the Leveler automatically adjusts volume levels up or down to compensate for signals that are softer or louder than normal. Q: What can this 'Leveler' do for me and my customer? The two most common applications for the Leveler are to control music sources which have been recorded at different levels, and to control different levels of speech caused by the person(s) speaking and/or their varying distances from the microphones. [. . . ] Once a High-Pass Filter or Low-Pass Filter is enabled, a square cursor appears in the upper graph area to allow frequency adjustment for that filter. The effect of High-Pass & LowPass Filters is also shown in the lower graph area. NOTE: HPF & LPF are NOT affected by the Flat button. They may only be deleted by means of their individual menu boxes. Bypass EQ defeats all parametric & graphic equalization filters for that channel, without changing actual settings. 7 SETUP GAIN MATRIX #2 SCREEN The Gain Matrix #2 screen provides a channel-to-channel (2x2) mix matrix (identical to Gain Matrix #1), which can be used to adjust the amount of signal being routed from each channel to the other. From the factory, Channel 1 is routed to Output 1 only, and Channel 2 is routed to Channel 2 only, providing two independent signal paths. Levels are adjusted by dragging the corresponding `faders' up or down. `Meters' are provided on each channel to display input/output levels at Gain Matrix #1. NOTE: For best performance, adjust levels so the meters show occasional peaks in the yellow area, but never to the top (red). Invert allows the phase of each corresponding signal path to be reversed (180°). The NMP200 has two basic applications which utilize Gain Matrix #2: 1) Each channel of processing is dedicated to either Input 1 or Noise signal, using Gain Matrix #1 (see Gain Matrix #1 screen on pg. Switching between Input 1 & Noise signals (to either Output) is then accomplished via Gain Matrix #2 presets. This is effective when only a single output (zone), or two outputs (zones) with independent delay, are required. 2) Gain Matrix #1 presets can be used to switch between Input 1 or Noise signal being routed to either Output (see Gain Matrix #1 screen on pg. Each channel of processing is dedicated to a specific Output (zone), via Gain Matrix #2. Separate EQ presets for Input 1 & Noise signals, as they appear at each output (zone), can also be used. This is effective when two outputs (zones), each with dedicated processing, are required. Of course, the NMP200 can simply be configured for processing Noise (or Input 1) signal only, at both Outputs. 8 SETUP DIGITAL DELAY SCREEN The Digital Delay screen is used to adjust delay time settings for each Output. Delay time is shown in the window, with adjacent buttons providing the up/down adjustments. Coarse buttons change the delay time in 1 milli-second increments. Fine buttons change the delay time in 21 micro-second increments. Delay time may also be entered directly into the window, but will be rounded to the nearest available setting.
