FEATU RES

All-Electronic Reverberation Amplifier with High
SN and Low Distortion

This is an all-electronic reverberation amplifier which in-
corporates an audio-use delay element known as a buck-
et brigade device (380). Unlike conventional mechanical
reverberation amplifiers this particular unit is not in the
least affected by external vibration or fluctuations in the
reverberation effect. Furthermore, the delay element
features a C MOS IC semiconductor which contributes
greatly to yielding such impressive characteristics as a
high signal-to-noise ratio of 90dB and a low total har-
monic distortion (at ikHz, lV) of 0.05%.

TIME and DEPTH Controls to Adjust
Reverberation Effect

This reverberation amplifier comes with two handy con-
trols: the TIME control that allows the delay time to be
adjusted continuously and the DEPTH control which
allows the depth of the reverberation to be adjusted con-
tinuously. Using the two knobs in combination makes it
easy to produce the desired reverberation effect in line
with the music source which you are listening to.

Selection between Two Types of Reverberation
Effect

You can choose freely between two modes with this
amplifier. One mode, known as EFFECT-l, is the so-
called echo" mode when the reverberation components of
the original sound are made to last for a long time « a
feature which is effective in large halls. The other mode,
known as EFFECT-2, refers to a single reverberation
component which is generated to turn a solo vocal into a
chorus or duet. Make the most of these two effects to
derive more enjoyment and satisfaction from your music
source.

Visually Attractive Reverberation Effect Indicator

This indicator is designed to express the reverberations
produced visually. The flickering of the blue rings of
light indicate the effect at a glance. When the reverberation
time is long, the flickering intervals will increase, and
conversely when the time is short, these intervals will
decrease.

Another function of the display is to display the
strength of the reverberations: the more reverberation
components, the brighter the rings of light.

Smart, Slimly Designed Styling

The reverberation amplifier has been slimly designed
with the beautiful reverberation effect indicator in the
center for a clean, fresh look. The height dimension of
the front panel conforms to the EIA" standard 2U size
format. Using the optional rack mount adaptors [IA-
RlO4), the reverberation amplifier can be installed in
a rack conforming to ElA specifications.
