Modern recording uses three dynamic control techniques which
may detract from the original dynamic range; reduction of
transient peaks, overall compression of loud levels and upward
manupulation of soft levels. The RG-l will correct dynamic distor-
tion in each of these areas, increasing the contrast and virtually
restoring the original live program. In order to obtain maximum
benefit from this unit, please read the following instructions
carefully.

l T RG-1 FEATURES

Broadens Dynamic Range

The dynamic range of the music source can be expanded by
employing the RG-l as a stereo system adaptor unit. No prepro-
cessing is needed and only ordinary program sources, such as
records, FM broadcasts or tape music,.are required. The dynamic
range is expanded by making large signals larger {while low signals
remain unchanged), resulting in a powerful and sharp rendition
of the source. This has the effect of bringing performers right into
the listening room, and especially pulsive sources such as rock and
soul are given a broad new dimension.

Preserves Natural Impression

Attack and release characteristics of the audio signal are preserved
by a fast and slow response (mixed) double action control signal
that prevents unnatural impressions in the reproduced sound.

Noise Reduction Effect

A noise reduction effect is also included which reduces underlying
source noise. Tape hiss, motor rumble and other background
noises are reduced by the circuit properties of this unit, so that
low noise, exciting stereo sound can be enjoyed

Faithful Reproduction Function

The sensor section which produces the control signal is provided
with an energy distribution filter, to ensure that the expansion
function is not trigged by noise components. However, expansion
is not limited to instruments whose fundamental frequency is close
to the center frequency of the energy distribution filter, since all
musical instruments produce harmonics which are strongest when
CONTENTS 2 the instrument is played hard. Hence these harmonics activate the

sensmg crrcuit and control the degree of expansion, so that lower
frequency instruments are also enhanced.
