ANIMATION (Cont'd)
After vibrato is also available in two depths and delayed.
It will effect all
organ voices except rhythm voices, brite percussion, harmonic percussion, and
pedals.
~
tone cabinet output socket is incorporated in the organ to accept the Leslie
11 pin plug used on the self-powered series of tone cabinets.
The third and fourth audio channels, which are used exclusively for String
Ensemble will not be animated by the Leslie or after vibrato.
Since the tone
cabinet and headphone outputs feed two channel devices, it is necessary to pro­
vide for electrical mix of the String Ensemble in these accessories.
However,
a switch will be provided next to the tone cabinet plug, which will permit
acoustic mix for a 4 channel tone cabinet system.
The 340 organ is the first to use the new AV-64 Rhythm Unit, with improved
voicing and several new features.
The 340 Rhythm Unit has "TOUCH TEMPO", pro­
grammable pattern variations, rhythm breaks, rhythm fade, auto pedal, touch
pad break and silent/sound controls, lighted pattern buttons and overall up­
graded aesthetics.
PRO CHORD
The 340 organ has incorporated a new automatic harmony feature, Pro Chord.
When this effect is turned "on", harmony notes will automatically sound above
the
melody note(s) being played on the upper manual.
The notes which play
automatically are programmed from the chord notes being played on the lower
manual.
This effect is limited to 48 notes on the upper manual (Keys 10 thru
57).
The harmony notes sound in the same voices being used with the melody,
but at a slightly reduced level.
The tab control for this feature is located
with the Accents group on the control panel.
TRANSPOSER
The 340 incorporates a transposer in the upper left-hand endblock.
As in the
B-3000 this feature provides two semi-tone transposition steps above "A 440"
and four steps below.
Control means is achieved by lighted miniature push but­
ton switches.
REVERBERATION
A Type IV Reverb Unit is used to provide this feature.
The degree of REVERB
is controlled by a . slider pot mounted on the drawbar base.
An additional con­
trol tab is provided in the Leslie animation group to permit the LESLIE on REVERB
effect to be obtained at the player's option.
In this mode of playing some main channel signal is sampled by the reverb system.
Therefore, some of the "dry" organ voices have some degree of Leslie animation.
AUDIO SYSTEM
The basic audio system consists of two 10 watt and two 35 watt amplifiers.
One
35 watt unit is dedicated to the main "dry" channel, while the other powers the
Leslie channel.
The 10 watt amplifiers are dedicated to amplifying the String
Ensemble channels.
