Bass Tone Control Frequency Response
Tilt
The Tilt parameter can be thought of as a straight line that pivots on a
fulcrum at 1kHz to correct the overall tonal balance of source material. The
range is -3.0dB to +3.0dB, referenced to the Treble level. This control,
adjustable in 0.2dB increments, is useful on many older recordings, or when
the desired tonal balance cannot be achieved at the listening position. The
Tilt control does not alter the tonal balance of the rear or side speakers.
A Loudness Contour parameter which boosts bass information, provides
more balanced reproduction at low volume listening conditions. Once you
have calibrated DC-1 output levels, set the LOUDNESS parameter ON to
provide the ideal amount of boost for any given volume setting. This
parameter does not affect the sound of the rear or side speakers.
