Q: What is this 'Leveler' inside the MSP11 & MSP22e? The Leveler function, in the Gain Manager section of an MSP11 or MSP22e, 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.
& soft-gating gain functions, as well as a combination of 1/3-octave & Setup pgs. 4~11 parametric equalization functions, with additional high-pass & low-pass filters, and it provides calculation for proper distance/delay settings. The MSP11 is Logic Inputs pgs. 12 & 13 covered by a five-year warranty.
FRONT PANEL FEATURES MSP11 On Indicator: When AC power is applied to the MSP11, this red LED will light indicating power to the unit is On. When power is removed, all current settings will be stored in non-volatile memory and recalled when power is restored. NOTE: During setup the MSP11 may instead be set to recall a special preset whenever power is restored (see Setup on pg.
Input: This plug-in barrier strip provides the balanced analog line- and a null-modem cable are provided for programming (see Setup level Input to the MSP11. For balanced input, wire high to (+), low on pg. 3). NOTE: The Serial Port can also transmit commands to (-), and ground to ( ).
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 MSP11 file is opened. Gain Manager, EQ, &...

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 level or use the MSP11 parametric equalizer to eliminate feedback nodes, before re-enabling the Gain Manager.

SETUP PARAMETRIC EQ SCREEN The Parametric EQ screen is used to adjust equalization. Up to 34 bands of equalization, plus high-pass & low-pass filters, are available. NOTE: Parametric & Graphic equalization techniques may be used simultaneously, as long as the total number of bands does not exceed 34.

SETUP GRAPHIC EQ SCREEN The Graphic EQ screen is used to adjust equalization. Up to 34 bands of equalization, plus high-pass & low-pass filters, are available. NOTE: Parametric & Graphic equalization techniques may be used simultaneously, as long as the total number of bands does not exceed 34.

SETUP DIGITAL DELAY SCREEN The Digital Delay screen is used to adjust delay time settings. 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.

Binary Mode when simply defining individual Logic Inputs. Power-Up Actions allows specific actions to be assigned for the MSP11 to perform each time power is turned on. Echo Character selects the RS-232 ASCII character which will be transmitted via the MSP11 Serial Port whenever the selected Logic Input is switched.

From the factory, Remote Control Buttons have equivalent ASCII characters permanently assigned to them (see RS-232 Control on pg. 14). Therefore, a Remote Control Button can be assigned specific ‘actions’, which the MSP11 will then perform whenever the equivalent ASCII character for that button is received. From the factory, Remote Control Buttons have no pre- programmed functions.

Device Name allows a custom name to be given to the particular MSP11, by entering up to 30 characters of text. The Device Name will be stored in the MSP11 memory, and will be displayed on the title bar of the Main screen whenever that MSP11 is accessed with the software.
LOGIC INPUTS Eight Logic Inputs are available on a rear panel 9-pin Sub-D (female) connector. Logic Inputs allow remote control of the MSP11 via external circuits, such as switches, contact-closures, active driver circuits, and/or ‘open-collector’ logic outputs. From the factory, Logic Inputs 1~8 have no pre-programmed function.
Page 17
LOGIC INPUTS Multiple contact-closures or ‘open-collector’ logic outputs may be wired in parallel to a single Logic Input (see diagram below). Logic Outputs and contact-closures should be rated for at least 5 Volts / 1mA operation. Low-current / dry-contact closures are recommended for reliability.

RS-232 CONTROL The MSP11 has an RS-232 Serial Port, which allows it to be controlled by a computer (see Rear Panel Features on pg. 3). In addition to the PC Control Software, the MSP11 offers two other methods of computer control.
Serial Port Data Communications Parameters: The MSP11 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 MSP11 utilizes a subset of the standard 7-bit ASCII character set. The eighth data bit of each character (the most significant bit) should always be 0.
