MG2500 INTRODUCTION pg. 2 The Atlas Sound MG2500 Sound Masking Processor provides a digital pink- noise generator, a balanced line-level audio input, and a 2-channel DSP processor, all in a single rack-space unit. Noise & audio levels, plus two channels of EQ, gain management, & delay, are adjusted via computer pg. -

(see RS-232 Control on pg. 13). The Link Port of one device simply connects to the Serial Port of the next device (and so forth). NOTE: All but the final MG2500 in a system should have the Link Switch pressed in (see below). The Link Port has the following pin assignments (right-to-left &... -

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 MG2500 file is opened. Gain Matrix #1, Gain Manager, EQ, Gain Matrix #2, & Delay screens are then available from the Main screen. - Page 6 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 MG2500 can simply be configured for processing Noise (or Input 1) signal only, at both Outputs.
- Page 7 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 MG2500 parametric equalizer...
- Page 8 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 9 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 10 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 MG2500 can simply be configured for processing Noise (or Input 1) signal only, at both Outputs.
- Page 11 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 12 Binary Mode when simply defining individual Logic Inputs. Power-Up Actions allows specific actions to be assigned for the MG2500 to perform each time power is turned on. Echo Character selects the RS-232 ASCII character which will be transmitted via the MG2500 Serial Port whenever the selected Logic Input is switched.

‘new’ file. The Serial Number and Firmware Version are not displayed for ‘new’ (‘off-line’) files. Device Name allows a custom name to be given to the particular MG2500, by entering up to 30 characters of text. The Device Name will be stored in the MG2500 memory, and will be displayed on the title bar of the Main screen whenever that MG2500 is accessed with the software. -
Page 14: Logic Inputs
LOGIC INPUTS Sixteen Logic Inputs are available on a rear panel 25-pin Sub-D (female) connector. Logic Inputs allow remote control of the MG2500 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 15: Serial Port
Serial Port Data Communications Parameters: The MG2500 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 MG2500 utilizes a subset of the standard 7-bit ASCII character set. -

The Leveler function, in the Gain Manager section of an MG2500, 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.
