Madrigal Imaging N380 manual Balance mode

the balance mode

The record outputs may be disconnected (or “defeated”) by pressing the input selector button of the currently selected (to-be-recorded) input a second time. Doing so will toggle the record outputs on and off. The display will alternatively read the name of the chosen input and RECD OFF as shown below.

Defeating the record outputs eliminates even the possibility that the input im- pedance of a recording device could have an effect on the sound quality of the preamplifier. We recommend that record outputs be turned OFF when not in use.

The balance mode gives you extremely fine control over the relative volumes of the Left and Right channels, by changing the volume of one relative to the other in increments of 0.1 dB, up to 20.0 dB. (Beyond this point, the balance control will mute the output of the reduced channel entirely.) Once set, this inter-channel difference in volume remains the same regardless of output level and selected input, until it is changed again in the balance mode, or when AC power is inter- rupted (in which case the balance is reset to 0.0).

To enter the balance mode from the monitor mode, press the mode button twice (once from the record select mode). When the balance is set to a neutral position, favoring neither channel over the other, the display will show a double- headed arrow and “0.0” decibels—that is, that the channels are balanced with re- spect to one another.

Turning the knob (which serves as a balance control in balance mode) in either direction will change the balance in that direction. The display will reflect this by changing to the appropriate single-headed arrow to indicate the direction of change and by showing the number of decibels by which that channel has been increased (in tenths of a decibel), as below:

In this example, the right channel is 2.3 decibels louder than the Left.
