RadioFans.CN 收音机爱 好者资料库 Make-Up Gain Provides additional gain after the signal has been compressed to reestablish the nominal system signal level.The make-up gain has a range of 0dB (unity gain) to +15dB. Care should be taken not to o

3、verdrive the amplifiers input when applying this additional gain. Threshold Controls the minimum necessary mix bus signal level to trigger the module to begin compression. Clockwise rotation increases the necessary signal level required to trigger compression.The threshold is adjustable from -40dBV

4、to +10dBV with the center of rotation being approximately -10dBV. Compression Ratio The compression ratio control is adjustable in order to alter the dynamics of the signal above the limiting threshold.In the minimum position,the action of the compressor is light (compression ratio 2:1, approximatel

5、y),thereby resulting in mild compression.The maximum position provides “brick wall” limiting (infinite compression ratio), where no further increase above the threshold level will occur in the output signal. Module Installation 1.Turn off all power to the unit. 2.Make all necessary jumper selections

6、. 3.Position module in front of desired output module bay opening, making sure that the module is right-side up. Output modules will not fit in input module bays. Do not force an output module into an input module bay. 4.Slide module on to card guide rails. Make sure that both the top and bottom gui

7、des are engaged. 5.Push the module in to the bay until the faceplate con- tacts the units chassis. 6.Use the two screws included to secure the module to the unit. WARNING: Turn off power to unit and make all jumper selections before installing module in unit. Compressor Bypass Switch The Compressor

8、Bypass Switch provides instant comparison between com- pression and no compression during the tuning of the system. Input The RCA unbalanced input provides a 20k-ohm input impedance.The unbal- anced input connects to the amplifiers front level control for the bay in which it is installed so that the

9、 input is not lost when using the output mod- ule. Jumper Selections Priority Level Jumper placement only affects the unbalanced input signal. The jumper placement determines whether the modules input can be muted by other input modules.When enabled, the input is per- manently set to the lowest prio

10、rity level. Hard / Soft Knee Jumpers For “brick wall” limiting and hard knee compression, set the J32 jumper to Hard. For soft knee compression, set the J32 jumper to Soft. Module Features When set to lower compression levels, the CMP1R can be used as a compressor to minimize the differences in leve

11、l of all of the inputs on the mix bus, or, when set to maximum compression, it can be used as a limiter to keep overall output at a desired level. All Bogen output modules include an unbalanced input that is controlled by the amplifiers input control so that the user is not penalized in number of in
