Input B-2 on the Monitor switch uses only the non-inverted signal.
Therefore, if you are feeding a balanced signal into B-2, there will be a 6
dB difference in level between B-2 on the Select switch and on the
Monitor switch. The level on the Select switch will be the higher one.
Note: Be careful not to create a feedback loop between the KBL an tape
recorder. This can happen by selecting the tape recorder output on the
Select switch and having the tape recorder set on "source". This set-up
takes the output of the tape recorder to the KBL, through the Record
output, back to the tape recorder inputs, and out the tape recorder
outputs to the KBL again. When doing Tape/Source comparisons always
use the Monitor switch for the tape recorder output and do the
Tape/Source switching on the tape recorder.
Use the Gain switch to adjust the overall gain of the KBL. The Low
position is 9 dB of gain; the High position is 15 dB. The LED indicator is
illuminated when the switch is in the High position. The switch can be
changed during listening at low and moderate listening levels. During
high level listening it is advisable to lower the volume before adjusting
the switch.
Use the Phase switch to reverse the absolute phase of the Main outputs.
The switch is functional for both the single-ended and balanced outputs.
The LED indicator is illuminated when the switch is set for phase
reversal.
When two KBLs are used, the Phase switch on one KBL can be used to
reverse the phase of one channel in relation to the other.
Many recordings have had their overall phase reversed during the
various processing stages. When the absolute phase and phase
relationship between channels is correct there are improved transients
and dynamic detail.

When a single KBL is used for stereo operation the function of the
Symmetry control is like a conventional balance control. Use it to
adjust for small level differences between channels. There are four 1
dB steps of attenuation and an Off position for each channel.
