(503) 641-7287 www. biamp. com blank print update September 7, 2005 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. 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. Example #1: A background music system utilizing a CD player as the primary source. [. . . ] Channel 1 provides the High-Pass Filter (high-frequency output) and Channel 2 provides the Low-Pass Filter (low-frequency output). NOTE: Channel 1 & 2 signals are typically mixed together before entering the Crossover section (see Gain Matrix #2 on previous page). From the factory, the crossover mode is disabled. To enable the crossover mode, release the Bypass buttons for both Channels 1 & 2. These buttons may be `released' independently for certain applications. For example: releasing only the Channel 2 Bypass button would provide a full-range signal from Channel 1, while Channel 2 would provide only low-frequency signals. This can be useful for sub-woofer applications. The crossover frequencies are adjusted by dragging the cursor left or right within the upper graph & lower graph areas. From the factory, Channels 1 & 2 are set for Linked Frequency, which allows adjustments made in either the upper graph or lower graph to affect both filters. Clicking on Linked Frequency will disable this function, and frequency adjustments can then be made independently for each filters. This allows Channel 1 & Channel 2 bandwidths to be overlapped or separated. Response selects the type of filter characteristics to be used for both filters. Low Pass Filter Slope selects the desired slope for the filter on Channel 2. High Pass Filter Slope selects the desired slope for the filter on Channel 1. CD Horn adds a high-frequency shelving filter on Channel 1 only, with adjustable gain (0~+18dB) and a 6dB/octave slope, as pre-emphasis for `constant-directivity' horns. `Meters' are provided on each channel to display input/output levels at the Crossover section. The order in which MSP22e processing blocks are positioned in the signal path may be customized (see Signal Path Order Form screen on pg. From the factory, Crossover is the fifth processing block, positioned between Gain Matrix #2 and the Delay. 9 SETUP DIGITAL DELAY SCREEN The Digital Delay screen is used to adjust delay time settings for each Channel. 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. [. . . ] NOTE: Baud rate may need to be changed when the MSP22e is being used in RS-232 systems with other products having a lower maximum baud rate. Link Port Connections: The 9-pin Sub-D (female) connector on the MSP22e rear panel provides the RS-232 compatible serial interface signals used for linking multiple BIAMP products within a system. The Link Port of one device simply connects to the Serial Port of the next device, and so forth (see diagram below). Link cables are available as an option (Biamp #909-0057-00). [. . . ]
