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 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.
