  • Page 3 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.

  • Page 5 EQ, gain management, & delay, are adjusted via computer Logic Inputs pg. 13 software. Sixteen presets can be recalled via contact-closures, RS-232, or other remote control options. The NMP200 carries a five-year warranty. pgs. 14 & 15 RS-232 Control NMP200 features include: Applications pgs.
  • Page 6 1 input MADE IN U.S.A. On Indicator: When power is applied to the NMP200, this red Link Switch: The Link Switch is used when connecting multiple LED will light indicating power to the unit is On. When power is devices in a ‘Link Port to Serial Port’...
  • Page 7 Once the software is started (and Comm Port Configuration is set), the control screens are accessed via the drop-down menus at the top of the opening screen. The Main screen appears whenever an NMP200 file is opened.
  • Page 8 (zone), can also be used. This is effective when two outputs (zones), each with dedicated processing, are required. See Office application on pg. 17. Of course, the NMP200 can simply be configured for processing Noise (or Input 1) signal only, at both Outputs.
  • Page 9 Therefore, after all system settings have been adjusted, temporarily bypass the Gain Manager as a test of system feedback stability. If acoustic feedback occurs, reduce the system amplifier levels or use the NMP200 parametric equalizer...
  • Page 10 SETUP PARAMETRIC EQ SCREEN The Parametric EQ screen is used to adjust equalization for each of the processing channels (Output 1 & Output 2). Up to 28 bands of equalization, plus high-pass & low-pass filters, are available per channel. NOTE: Parametric & Graphic equalization techniques may be used simultaneously on the same channel, as long as the total number of bands per channel does not exceed 28.
  • Page 11 SETUP GRAPHIC EQ SCREEN The Graphic EQ screen is used to adjust equalization for each of the processing channels (Output 1 & Output 2). Up to 28 bands of equalization, plus high-pass & low-pass filters, are available per channel. NOTE: Parametric & Graphic equalization techniques may be used simultaneously on the same channel, as long as the total number of bands per channel does not exceed 28.
  • Page 12 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. See Office application on pg. 17. Of course, the NMP200 can simply be configured for processing Noise (or Input 1) signal only, at both Outputs.
  • Page 13 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.
  • Page 14 Binary Mode when simply defining individual Logic Inputs. Power-Up Actions allows specific actions to be assigned for the NMP200 to perform each time power is turned on. Echo Character selects the RS-232 ASCII character which will be transmitted via the NMP200 Serial Port whenever the selected Logic Input is switched.
  • Page 15 BUTTON DEFINITION SCREEN The Button Definitions screen is used to assign specific ‘actions’ to remote control buttons. Although the NMP200 does not accept wall- mount (WMC) or infrared (IR-T) push-button remote controls directly, an accessory unit (RT) is available, which can translate these control ®...
  • Page 16 ‘new’ (‘off-line’) files. Device Name allows a custom name to be given to the particular NMP200, by entering up to 30 characters of text. The Device Name will be stored in the NMP200 memory, and will be displayed on the title bar of the Main screen whenever that NMP200 is accessed with the software.
  • Page 17 LOGIC INPUTS Sixteen Logic Inputs are available on a rear panel 25-pin Sub-D (female) connector. Logic Inputs allow remote control of the NMP200 via external circuits, such as switches, contact-closures, active driver circuits, and/or ‘open-collector’ logic outputs. From the factory, Logic Inputs 1~16 have no pre-programmed function.
  • Page 18 RS-232 CONTROL The NMP200 has an RS-232 Serial Port, which allows it to be controlled by a computer (see Front & Rear Panel Features on pg. 2). In addition to the BiampWin software, the NMP200 offers two other methods of computer control.

  • Page 19: Serial Port

    Serial Port Data Communications Parameters: The NMP200 communicates through the Serial Port at the factory selected rate of 38400 bits per second, with 8 data bits, 1 stop bit, and no parity. The NMP200 utilizes a subset of the standard 7-bit ASCII character set.
