4.1 General volume
The general volume of the organ can be adjusted with use of the Johannus Menu.
See § 5.4 General Volume.
4.2 Expression pedals
The organ has five expression pedals. One is configured as a crescendo pedal, the
others are configured as swell pedals for the existing divisions. The Pedal division
is combined with the Great division.
Using an expression pedal which is set as a swell pedal will next to the volume
also changes the timbre of the stops. By this the effect of the swell box shutters of
a pipe organ is simulated.
4.3 Cathedral
The organ is equipped with the Adaptive Surround Reverb ASR-12 system. This
effect provides a spatial reproduction of the organ sound.
With use of the Johannus Menu the following settings are adjustable per
intonation style: Reverb Program and 3D Surround effect. See § 5.12 Reverb
Settings.
Organ: The volume of the organ can be adjusted with the ORGAN volume
control.
Cathedral: The reverb volume can be adjusted smoothly with the
CATHEDRAL volume control.
4.4 Intonations
The organ has 12 intonations, divided in three styles: Romantic (ROM), Symphonic
(SYM) and Baroque (BAR) and four variations per style: A, B, C and D.
Select an intonation style by pressing the ROM, SYM or BAR piston. Select an
intonation variation by pressing the A, B, C or D piston.
4.5 Stops
The stops are activated via stop draw knobs, pre-programmed memory locations
or capture memory locations.
The lamp of the draw knob lights up when the associated stop is active.
The stops are divided into the following groups:
Pedal: Activates the stops associated with the Pedal.
Choir: Activates the stops associated with the Choir.
Great: Activates the stops associated with the Great.
Swell: Activates the stops associated with the Swell.
Solo: Activates the stops associated with the Solo.

of the display. The lamp in the stop switch lights up when the associated voice is
active.
See chapter 6 ORCHESTRALS for more information on solo- and orchestral voices.
Solo- and orchestral voices are standardly playable from a factory defined manual.
This can be changed via Quick Access, see § 4.10.2 Orchestral settings, and via the
Johannus Menu, see § 5.9 Orchestrals.

It is advisable not to use the Manual Bass while playing the pedal board to avoid
double bass tones.
4.7 Accessories
Antiphonals
On an instrument with separate divisions (each division having its loudspeakers)
one or more divisions may be connected to a second speaker set. The division
concerned can be switched from the main speaker set to e.g. a speakerset behind
the choir, by means of the switch Choir Antiphonal or Solo/Eth. Antiphonal.
CAN: Cancel
Cancel is a function to switch off all stops at once.
Cantus Firmus (melody coupler)
Cantus firmus: Latin for ‘fixed voice’ or in organs ‘solo voice’ or ‘melody coupler’.
Couples the Swell monophonic to the Great. Only the highest key that is played on
the Great is coupled from the Swell to the Great.
With use of a solo registration on the Swell in this way a solo is heard while
playing only on the Great.
If only the highest key of a chord is released, the key activated by melody coupler
is dropped until a new highest key is played.
Use the stop switches to activate the melody coupler on swell or melody coupler
on choir by
CH: Chorus
Chorus is a function for lightly detuning the organ stops to give it a broader and
livelier sound.
Fix Accessories
When the couplers and the tremulants are used in the fixed (preset) combinations
or free (capture) combinations or when the 0-piston or CAN piston is used, the
couplers and tremulants will change with it. This can be prevented by pressing the
Fix Accessories stop switch. As long as this tab is switched on, the couplers and
tremulants can only be switched on or off manually
KT: Keyboard Transfer
Keyboard Transfer is a function to switch the manuals of the Choir and the Great.
When Keyboard Transfer is active manual 1 is the Great manual and manual 2 is
the Choir manual. Keyboard Transfer also switches the divisional pistons of the
relevant manuals.
MB: Manual Bass (bass coupler)
Couples the Pedal monophonic to the Great. Only the lowest key that is played on
the Great is coupled from the Pedal to the Great.
If only the lowest key of a chord is released, the pedal key activated by the
Manual Bass function is dropped until a new lowest key is played.
Activate the Manual Bass with the MB piston.
It is advisable not to use the Cantus Firmus in combination with the coupler
SWELL - GREAT because this overrules the solo function of the Cantus Firmus.

P.O./ A.O.: Pipes On/Ancillary Off
If the instrument consists of a combination of a number of pipe organ voices and a
number of electronically generated voices (a so-called hybrid instrument) the
piston A.O. (Ancillary Off) may occur on the instrument mostly in combination
with the piston P.O. (Pipes On). Pressing the P.O. piston activates the pipe organ
part of the combined instrument. Only after pressing the Pipes On piston can the
voices of the pipe organ part be switched on or off with the appropriate stops
Pressing the Ancillary Off piston switches off the electronic voices of the hybrid
organ all at once.
REC: Recall
Recall is a function to cancel the last change of registration.
RO: Reeds Off
Reeds Off is a function to switch off all reed stops simultaneously. As long as this
piston is pressed, no reed stops can be activated. When this function is switched
off, the reed stops that were on are activated again. Activate the Reeds Off with
the RO piston.
SEQ: Sequence On/Off
Sequence is a function for sequential selecting general capture memory locations.
1. Select a general capture memory location to start (for example level 2,
location 2).
2. Pressing a random piston of the memory locations of the Pedal selects the
previous general memory location, pressing a random piston of the general
memory locations selects the next general memory location.
S/S: All Swells to Swell
All Swells to Swell transforms the swell pedal of the Swell into a swell pedal of the
entire organ. The other swell pedals will be switch off then.
If no expression pedal is set as swell pedal of the Swell, the S/S stop switch cannot
be activated.

The transposer setting can be read on the display (Trans: …).
1. Press the TRANS. piston.
2. Use the - and + pistons to set the pitch.
3. When the transposer change needs to be saved, press the SET piston in the
time the TRANS. piston is lit.
ZIMB.: Zimbelstern
The American Classic 770 has been prepared for the connection of an external
Zimbelstern with an operating voltage of 12 Volt. This can be activated by the
ZIMB. piston.

The current choice of the voice and the manual assignment appears on the
display. See § 5.9 Orchestrals for further steps.
The actual state of the memory lock is also reflected in the SET piston. This piston
will light up when the key of the memory lock is turned to the right, indicating
that the SET piston can be used.
If the SET piston is not lighted, no menu functions for which the SET piston needs
to be pressed can be used.
This function is not available if no expression pedal is set as
crescendo pedal.
