Less brilliant than the Cymbal 11, grows fuller at the lower pitches.

3.12 Testing of the U/Man I Fixed Stops

Move the test lead (-15 V) from the preamplifier terminal "S 4" to
terminal "S 2": Repeat the listening tests by activating the U/Man
stop tabs again and comparing the sounds with the descriptions of
the preceding chapter. This time, however, the filter boards directly
adjacent to the tab switches are responsible for the sounds.
Both U/Man voicing blocks are equipped identically. It might be
interesting to compare the sounds between the filters from either
block. If you switch the test lead back and forth between the pins
S2 and S4 you alternatingly hear the same stop (or stops) coming
from two different voicing blocks (adjust the M/Man and U/Man
volume control for balanced volume).
Remove the test lead from the preamplifier.
3.13 Testing of the Tongue Tab Switches
"Drawbars(or) Fixed Stops"
Lower Manual
1. Mate the connector leading to plug 1 on the lower manual
fixed stops, referring to Fig. 89.
2. Flip the switch "Drawbars/Fixed Stops" downwards (left-
most switch of the group "Lower Manual Fixed Stops").
Leave the next two switches to Wersivoice")in their up
position.
3. Activate a few stops.
AM 075 (Part)
4. Pull a few L/Man drawbars about halfway, must include the
volume drawbar(left-most black drawbar of the group).
5. Mate the connector leading to plug 4 of the right preamplifier,
referring to Fig. 7 0.
6. Play on the lower manual. The fixed stops should sound
from the right speaker (provided the channel selector switch
still is in its up position).
Flipping the switch " Drawbars/Fixed Stops" up again, the
fixed stops should be silenced and the drawbars should
sound instead.
Turn on all L/Man fixed stops.
7. Pull the L/ M an volume control (grey drawbar) all the way.
8. Pull all L/ Man drawbars (12 drawbars).
9. Hold a chord on the lower manual and flip the tab "
Drawbars/Wersivoice" back and forth. First, adjust the
trimpot P 5 "Volume" on the right preamp to a suitable
listening volume.
Second, adjust the trim pot P1 on GP 1 (L/Man) to balance
the fixed stops volume with the draw bar volume with a slight
emphasis of the fixed stops, that is, the fixed stops should
sound a little bit louder.
Should you be unable to reduce the fixed stops volume
sufficiently, reduce the resistor R6 on G P 1 (L/Man) from 22
kOhms to10 kOhms. (Hint: lf you parallel a second 22 kOhm
resistor piggy-back style onto the first one you don't have to
dismount the voicing block.)
