Q: What is this ’Leveler’ inside the MG2500?

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.

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: A background music system utilizing a CD player as the primary source. Since CDs can be recorded at different levels, the volume from one CD to another can vary significantly. In the background music system it is desirable for the music to maintain a consistent level. A Limiter or Compressor could be employed, but they would only squash the dynamics, and diminish the quality of the music signal. A Leveler, on the other hand, actually controls the overall level of the signal, without adversely affecting the dynamics of the signal itself. Therefore, a Leveler can be used to provide a constant volume from the system, regardless of varying CD levels. This is also true for systems with a variety of music sources (i.e...cassette, tuner, etc.).

Q: How should I adjust this ’Leveler’ to do what I want?

1)Using a typical input signal, adjust the source output and the MG2500 input for proper levels.

(The MG2500 software input meter should indicate occasional peaks into the yellow, but never to the red.)

2)Select the Gain Manager section of the MG2500 software.

3)Bypass all Gain Manager functions except the Leveler.

(This allows the Gain Reduction meter to be used for setup of the Leveler specifically.)

4)Adjust the Leveler ’threshold’ so the Gain Reduction meter indicates the desired amount of gain reduction.

(The amount of gain reduction employed on ’normal’ level signals equals the gain available for raising ’softer’ level signals.) (Example: Play a normal level CD. Adjust for 6dB of gain reduction. CDs with lower levels can be raised as much as 6dB.) (Likewise, ’louder’ signals will be lowered. The Leveler will attempt to bring softer or louder signals to the threshold level.)

NOTE: The Gain Manager provides gain reduction even on input signals of nominal level. Therefore, all subsequent software meters will indicate the resultant lower level. This lower level can then be compensated for by increasing the input level on the next device in the system (i.e...power amplifier).

CAUTION: The Gain Manager can increase gain for lower level signals. Therefore, once all of the 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 MG2500 parametric equalizer to eliminate feedback nodes, before re-enabling the Gain Manager.
