COUPLERS
Couplers I-Pedal and II-Pedal allow those stops which have been drawn on Manuals I and II to play
on the Pedals also.
Coupler II-I adds the stops drawn on the Swell to the Great manual.
The corresponding controls appear as stop tabs on the extreme right of the relative section, as thumb
pistons under manual I.
The thumb pistons are reversible: pressing once activates the couplers; pressing again they are
deactivated. It is also possible to deactivate the couplers manually when they have been activated
with the thumb pistons and vice versa.
COMBINATION ACTION
HYMNUS IV offers 5 general combinations with automatic return to hand-set registration.
The corresponding controls appear as thumb pistons numbered from 1 to 5 under Manual I.
The LEDS indicating the setting of the 5 combinations are located above Manual II.
Thumb pistons below Manual I (from left to right):
F = COMBINATION SET
O = HAND-SET REGISTRATION
1 to 5 = COMBINATIONS
A = GENERAL CANCEL
TO SET A COMBINATION
1) Press the tabs of the desired registration.
2) Press and HOLD the F thumb piston and press any one of the thumb pistons numbered from 1 to 5.
3) Release both pistons. The selected registration is now memorised.
4) Bring all tabs to zero, using the A thumb piston and repeat the operation on thumb pistons which
are still available.
TO MODIFY A COMBINATION:
1) Press the numbered thumb piston corresponding to a previously memorised combination.
2) Add, cancel or change the stops required.
3) Press and HOLD the F thumb piston and press the same numbered piston that was pressed in
stage 1 above.
4) Release both pistons. The modified registration is now memorised.
It is possible to effect a temporary change to the combination by hand, without the use of the F control.
In this case, if the same numbered thumb piston is pressed, the original registration will be restored.
TO ERASE COMBINATIONS PARTIALLY OR TOTALLY:
1) Press the A control, checking that no stops are activated.
2) Press and HOLD the F thumb piston and press the numbered piston relative to the combination
that is to be cancelled. Its contents are now erased.
AUTOMATIC RETURN TO HAND-SET REGISTRATION (O-PISTON)
While playing with a hand-selected registration, it may be necessary to use one or more combinations
that have already been fixed. In this way, the original hand-set registration will be either cancelled
or modified. However, by pressing the O piston, the original hand-set registration will be automati-
cally restored. If you wish to cancel this also, press the General Cancel piston A.
