minimum. It is not possible (nor desirable) to achieve total
silence since the swell pedal volume control circuitry is
designed with a slight treble and bass boost at low volumes.
5. Set all channel selectors to "left" and adjust the " Null" on
the left preamplifier.
6. Depress the push button " Reverb I°' on the right control
panel. Depress the swell pedal fully. Hit a chord very briefly
and listen for the reverb sound to decay. If no reverb exists,
flip the toggle switch near the M/Man fixed stops (under the
lid).
7. Depress the " Reverb II" switch in addition to " Reverb I".
The reverb decay should last longer. Adjust the trim pots P 2
" Reverb" on both preamplifiers for a suitable reverb time.
Don't overdo it. We recommend centre of rotation.
8. This is a good time to set the volume and tone controls on
the preamplifiers too. Set the treble control (top control) and
the bass control (centre) to the centre of rotation on both
upright boards on the preamplifiers. Later on, when you get
accustomed to the organ's sound, you may want to touch up
these settings to suit your taste. Set the volume controls
(bottom control) Such that you achieve the highest desirable
volume from your speakers when you play with "full organ"
and a fully depressed swell pedal. This gives you the proper
dynamic volume range.
3.25 Testing of the Swell Indicator
1. Mate the connectors of branch 8.1 with the pins on the swell
indicator board L A 1, referring to Fig. 85. Depending on the
swell pedal position, a few LED lights should be lit.
2. Set the swell pedal to the low volume stop. None of the LED!
or maybe the bottom one should light up.
3. Set the swell pedal to its high volume stop. If necessary,
adjust the trim pot on the board LA 1 such that all LED's are
just lit. From now on, you will be able to anticipate the to be
expected volume even before you start playing.
3.26 Testing of the Key Pop
1. Mate the connector with the pins on the board H P 1,
referring to Fig. 86.
2. Set up the 8' drawbar only on both the U/Man and the
M/Man. Verify the proper sound.
3. Depress the button "Key Pop" on the right control panel. Play
both U/Man and M/Man again. The 8' drawbar sound should
still be there but a short and scratchy "key pop" everytime a
key is depressed should remind you of the days when dirty
key contacts were a common nuisance. The intensity of the
key pop sound can be adjusted on the board HP 1 by means
of P1 for the M/Man and P 2 for the U/Man.
Remember: The key pop can be turned off!!
3.27 Testing of the Rhythm/Auto Accompaniment
Complete the installation and wiring of the rhythm and auto
accompaniment respectively, consulting the assembly manuals AM
480 (rhythm), AM 481 or AM 841 (accompaniment) and AM 485
(Wersimatic Galaxy).
Test the operation of the Wersimatic, referring to the manuals listed
above. When tuning the auto accompaniment, also consult the
following chapter.
