The line-matching transformer in the Control 29AV-1 has
been designed to minimize saturation; however, it is
recommended that the system be high-passed to prevent
very low-frequency content from overloading the
transformer and/or the driving amplifi er at high signal
levels. The high-pass requirements vary according to the
tap settings and number of speakers connected in
parallel. The following chart will eliminate risk of
saturation, even at full-voltage (70V or 100V) peaks.
Reducing the drive voltage will enable a corresponding
reduction of high-pass frequency (24 dB/octave high-pass
slope).
