Hammond 340107 - Rhythm Unit and Special Features

r":
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.
