SAFETY NOTICE
Great care has been taken in the design and manufacture of this product to assure that no
shock hazard exists on any exposed metal parts. Internal service operations can expose the
technician to hazardous line voltages and accidentally cause these voltages to appear on
exposed metal parts during repair or reassembly of product components. To prevent this, work
on these products should only be performed by those who are thoroughly familiar with the
precautions necessarywhen working on this type of equipment.
To protect the u.er, It I. required that all enclo.ure part. and .afety Interlock. be re.tored to
their original condition and the following
te.t. be performed before returning the product to
the owner afterany .ervlceoperation.
Plug the AC line cord directly into a line voltage AC receptacle (do not use an Isolation
transformer for this test) and turn the product on. Connect the network (as shown below) In
series with all exposed metal parts and a known earth ground such as a water pipe or conduit.
Usean AC VOM of 5,000ohms per volt or higher sensitivity to measure the voltage drop across
..-.
the network. Move the network connection to each exposed metal part (metal chassis, screw
heads, knobs and control shafts, escutcheon, etc.) and measure the voltage drop across the
network. Reverse the line plug and repeat the measurements.
Any reading of 4 volts RMS or
more is excessive and Indicates a potential shock hazard which must be corrected before
returning the product to the user.

HOW THE ORGAN OPERATES
GENERATOR SYSTEM
Tone generation is accomplished by using the 6 channel 440/Multiplex generator
system for melody, accompaniment and pedal voices. The 434/435 LSI system gen-
erates the pedal tones in Ease of Play modes while an additional 435 LSI gene-
rates the arpeggiator tones. Therefore, the organ has the equivalent of eight
tone generating systems. The Multiplex generators are assigned to: (1) Upper
Manual Synthesis (2 drawbars); (2) Lower Manual Synthesis (9 drawbars); (3)
Lower String Ensemble and Tab Voices; (4) Brite or Synthes~s Percussion; (5)
Upper Manual String Ensemble, Synthesizer Voices, and Tab Voices; and (6) Pedal
Voices.
Instead of using "Second Voices
M on
this organ, five "full time" tab voices on
the upper manual and three on the lower are used. The upper manual voices are
TUBA 16', POST HORN 8', KINURA 8', DIAPASON 8', and VIOLIN 4'. The lower manual
voices are DIAPASON 8', HORN 8', and VIOLINA 4'. As implied in the "full time"
description they will add to all other voices.
In order to make the organ as easy to playas possible, it has been necessary to
establish some priorities for the Upper, Lower and pedals. They are as follows:
1. UPPER MANUAL

solo presets,
and/or reverse
or PISTONS are

b. BASS GUITAR adds to both drawbar tones.
c. PEDAL SUSTAIN effects 16' and 8' pedal pitches and couples LIM tones.
d. PISTONS have priority over all pedal voices.
e. Lower to pedal coupler functions at all times.
REVERSE COLOR PRESETS
The 340 incorporates the Hammond reverse color keyboard presets on both upper
and lower manuals. As in the past, this feature provides for 9 preset division
voices, 2 programmable division presets and a cancel key on each manual.
The specific voices used on the 9 preset voices on upper and lower manuals are
summarized in Table 1.
PISTONS
Nine combination pistons provide the selective performance as shown in Table 2.
Five of these are essentially the same preset voices and functions used on the
333. The four new pistons provide immediate set ups for "Solo Instruments" on
the Melody Maker, "Cathedral" organ, "Full Theater" organ and Solo Strings.
The pistons are controlled by nine lighted momentary push buttons and a cancel
button (not lighted) mounted in the front strip to the left of the Arpeggiator
controls. The buttons are white and are marked 1 through 9 and C (cancel).
PERCUSSION DIVISIONS
The
upper manual has provision for both synthesis and brite percussion. The
synthesis group includes 1st, 2nd, 3rd, 4th, 5th, 6th and 8th harmonics, VIBRA-
HARP, TWIN MALLET MARIMBA and CHIME SOLO. The brite group includes five per-
cussion voices. These are PIANO, HONKY TONK PIANO, HARPSICHORD, BANJO and
PIZZICATO. In addition, a PIANO SOLO'preset is provided which cancels all
upper manual voices.
A REPEAT tab and variable rate pot which effects all voices in these divisions
except the solo presets is provided. The repeat rate range is from 2 to 17 Hz.
The
KEY CLICK feature provided on this model effects only drawbar tones on both
manuals and percussion harmonic tones on the upper manual.
To provide for balancing percussion voices against the other divisions of the
organ, a volume control is incorporated on the drawbar base.
A new DUAL VOICE feature is incorporated into the brite percussion. When this
tab is operated it turns on (couples) both 16' and 4' pitches and turns off the
8' pitch. It is controllable by either the control panel tab or the programma-
ble foot switch on the swell pedal.

PEDALS
The pedal bass has three additive voices -- 16' and 8' drawbar tones and
BASS GUITAR. In the normal playing mode pedals will perform polyphonically.
The pedals will have priority over AUTOCHORD or BASS WALK modes of automatic
pedal playing. For example, if the player is in the BASS WALK mode and de-
sires to inject his own bass pattern or legato pedal, he may simply play pedals
in the normal manner.
The automatic bass line will be cancelled and the pedals will sound with the
voices set up on the drawbars or tabs. On release of the pedal the automatic
bass will again sound at the start of the next programmed bass note as deter-
mined by the Rhythm Unit tempo.
STRING ENSEMBLE
The Model 340100 has a full complement of string voices. The controls are
mounted in the upper right-hand endblock. The string voices consist of three
pitches (16', 8', and 4') on the upper manual and three pitches (16',8' and
4') on the lower. Independent controls for string ATTACK, SUSTAIN, and VOLUME
are provided for each manual. Separate rocker tab controls have been provided
to turn SUSTAIN "on". This allows the player to preset the amount of this
effect. The SUSTAIN controls on this endblock also control the degree of sus-
tain on other voices as noted earlier under priorities. The BRILLIANCE tab
will effect the strings.
In order to achieve optimum performance of the String Ensemble group, three
channel acoustic mix is used.
SYNTHESIZER VOICES
The 340 incorporates the identical Melody Maker performance used in the 333
organ. The controls are mounted in the lower right-hand endblock on the 340.
EASE OF PLAY
The 340 utilizes the chord recognition capability of the 434/435 LSI to good
advantage. This performance includes true root/fifth AUTOCHORD, ONE-FINGER
CHORDS, programmed BASS WALK, and electronic MEMORY on the lower manual. In
addition, visual keyboard memory is provided by NOTE-A-CHORD.
AUTOMATIC ARPEGGIATOR
The 340 incorporates the FASCINATING FINGERS performance used in the 333 organ.
The controls and their location are also similar to the 333.
ANIMATION
The 340 incorporates a two speed Leslie Rotosonic unit. The organ also pro-
vides for manual separation so that upper and lower manuals may be indepen-
dently animated by the Leslie.
The percussion divisions, synthesizer instruments, pedals and rhythm voices
are channeled only through the main amplifier so that they will always be
"dry" with respect to Leslie animation.

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.

AUXILIARY CONNECTIONS
~ I Provisions are made for an auxiliary audio input and headphone. Both of these
connections are made by 1/4 inch phone jacks. The headphone jack is located
under the manual shelf on the right side of the organ. while the auxiliary input
circuit is under expression and designed to have an impedance of 47.000 ohms and
produce full output with 1/4 volt signal.
The headphone jack is wired to perform properly with either mono or stereo phones
without adapters. All organ speakers will go silent when the phone plug is con-
nected.
PROGRAMMABLE SWITCHES
TWo foot controlled switches are incorporated on the swell pedal. As on other
Hammond products. the right hand switch controls the Rhythm Unit to provide for
foot control of "cancel" or "reset" modes of operation. Since the auto arpeggia-
tor runs off the Rhythm Unit clock. it can also be controlled by the right hand
foot switch.
The left hand foot switch on the 340 is designed to be programmable to select
one of five functions. The function options will be PIANO SOLO. DUAL VOICE.
LESLIE SPEED,
RHYTHM FADE and RHYTHM BREAK. The programmable selector switches
are push type and located in the lower left-hand endblock. This feature is
called PRO FOOT.
LIGHTING
~
In addition to lighted controls in several areas, the 340 incorporates a music
desk light and control panel light. Lights are controlled by a switch mounted
on the rhythm control panel. However, the organ power ON/OFF switch will control
all the line power to the organ. Therefore, the lights can not be turned "ON"
unless the organ is "ON".
NEW AV-64 RHYTHM
/"'
The 340 is the first organ to use the new AV-64 Rhythm Unit. This unit has a
number of new features in both musical performance and control areas. Feature
highlights are optional TOUCH TEMPO or adj us't abl,e tempo rate; Silent/Sound touch
pad control; Six composed Rhythm Breaks assigned to 12 of the 16 patterns; Dedi-
cated touch pad control for Rhythm Breaks or optional foot switch control; Player
Programmable rhythm pattern variations; Rhythm Fade; Optional Manual Sustain in
AUTOCHORD mode; Lighted momentary pattern switches to provide good identifica-
tion and quiet operation; Lamps Off with automatic "on" triggered from pattern
switches; and overall improved voicing. The following paragraphs describe in
detail the overall performance of this new rhythm unit.
PATTERNS
The pattern tracks. voice assignments, names and order are identical to our cur-
rent AV-64 as used on the 333, 328 and 232 organs. However, the voice generators
have been revised using as many digital parameters as possible to obtain better
and more consistent voicing from organ to organ.

I
J

-------
PATTERNS (Cont'd)
The same "follow the player' optional voices are available on the new unit;
namely, Brush and Snare on the lower manual and Bass Drum and Cymbal on the
pedals. Assigned voices sound only when the rhythm unit is not running.
Pattern order and names are shown in Figure 1 as are location of the "follow
the player" voices. Also shown above the pattern buttons are the Continuous/
Touch Start and Foot Switch Reset controls. In the Continuous mode, the se-
lected rhythm pattern will sound at all times except when a "Break" is de-
sired. In the Touch Start mode the rhythm unit will not sound until a lower
manual or pedal note is played. In both modes on/off control is made by means
of the left hand touch p~d.
The foot switch mounted on the right side of the swell pedal can be used to
interrupt (silence) the rhythm pattern in either Continuous or Touch Start
modes wi thout los ing the tempo. However, when the Foot Swi tch Reset is "on"
and the player is in the Touch Start mode, the rhythm unit will not sound
again until a L/M key or pedal is played. In both Continuous and Touch Start
modes with foot switch operation in the Reset Mode the pattern starts at beat
one, measure one of Variation A or the first programmed variation.
RHYTHM BREAKS
There are six Rhythm Breaks assigned to twelve specific rhythm pattern. n
break assignments are shown in Table 3. A Rhythm Break is initiated by toU( -
int the break pad at any time when one of these patterns with an assigned bleak
is playing. The amount (number of beats) of break that one hears is determined
by the time of initiation.
If the break is triggered at the start of measure one beat one, two full mea-
sures of the break will play. If the break is triggered at any time after beat
one measure one, only the remaining period of the two measure cycle will play.
This musical logic was established to prevent the break from getting out of
step with the basic patter. However, it also permits the player to do creative
drum fills with 2 or 3 beat (etc.) breaks.
If the break is triggered when Autochord with Memory is on, the lower manual
and pedal will go silent. However, if one is holding any lower manual keys,
the manual will sound but will not be chopped during the break period. After
the break, the player must restore memory by playing the lower manual if he
wishes to hear manual and pedal in AUTOCHORD mode.
A break may be played as an introduction simply by touching the break pad be-
fore starting the rhythm pattern with the Silent/Sound pad.
On the 340 organ, break control can also be selectively triggered by the PRO
FOOT switch mounted on the left hand side of the swell pedal.
RHYTHM FADE
This feature can be controlled by a momentary switch mounted on the Rhythm
control panel or selectively triggered by the PRO FOOT switch. Fade will
smoothly reduce the level of all rhythm voices to inaudibility over a period
of approximately 10 seconds. To turn the voices "on" after a Fade sequence,
the player must again momentarily operate the Fade contro1(s) or perform a
Stop/Start cycle.

/"""'
,
This feature, which previously had been incorporated in the endblock on some
organs, is an integral part of the new AV-64. The Touch pad on t4eleft side
of the unit can be used optionally for normal rhythm start/stops with adjust-
able tempo rate or TOUCH TEMPO (TT). To set up the unit for TT operation,
the amber button located in the upper left hand corner of the touch pad must
be "on" (lighted). To establish the tempo in TT mode, the player simply taps
the pad four beats at the desired rate. If the rhythm unit is in the Contin-
uous mode, it will sound on the fifth beat. If it is in the Touch Start mode,
it will not sound until a lower manual key or pedal is played.
Red and green indicator lights are also located on this pad. When the red
light is on the rhythm unit is not playing. When the green light is on, the
unit is playing or ready to be played in Touch Start or Fade.
PROGRAMMABLE VARIATIONS
All previous Auto-Vari rhythm units have had fixed variation sequences, namely,
A,B,C and D. The new AV-64 on the 340 organ gives the player the option to
program his own sequence. To program a variation series, the Program switch
must be turned "on" and the Automatic switch "off". The player can then punch
the desired sequence by simply pushing the A,B,C, d buttons in the desired
order, omitting any he does not wish to hear. Each time a variation (A,B,C,C)
is pushed, it is automatically programmed to playa measure sequence (i.e.,
~,1,2,4,8). As many as 16 measure sequences can be programmed in any order.
The rhythm unit will play this sequence when the Automatic switch is turned
"on" and the rhythm unit started. This sequence will be remembered as long as
the Program switch is "on". When this switch is turned "off" the variation
sequence returns to A,B,C,D.
OTHER FEATURES
This new rhythm unit also includes a feature which gives the player the option
of having the lower manual chopped in the AUTOCHORD mode. This feature which
permits automatic Bass Walk or True Root/Fifth pedals without the rhythmic
chopped lower manual notes is turned on by means of the SUSTAIN CHORD switch.
The rhythm unit may be turned "off" (all lights turned off except TT or Silent/
Sound (red or green) by activating the Lights Cancel button located in the right
touch pad bezel. To turn on the lights, one simply pushes any rhythm pattern
button.
Tempo rate and measure identification is accomplished by means of two red lights
located in the right touch pad bezel. These are marked Bar I and II.
