Range Selector
Revolution Timpani have a mechanical range that produces a scalar range of a musical 6th (see diagram on page 4). Revolution timpani with optional fine tuner
can easily select a fundamental tone that is either lower or higher than normal. Changing the fundamental tone allows the player to select a range of a 6th from
within an octave of tonal range.
In addition to giving each size a larger range to choose from, the range selector can also increases the overlap in ranges between sizes. This larger overlap can
allow a player to not bring a specific size to a gig. For example, if a 23” timpani is only needed for a G3 tone, the 26” range can move from A2-F3 to B2-G3 to
play the G3 if the music allows.
Adjusting the fundamental does change the balance between the spring tension and the head tension. However, the strong design of Adams' spring tension
mechanism will usually accomodate a small change to the fundamental without the head tension affecting the pedal position. Always evaluate the pedal
performance after adjusting the fundamental.
Example:
A 29” with a F2 fundamental tone has a range from F2-D3. F2 Fundamental
Process
1
Move the pedal to the lowest tone.
3
Adjust spring tension if necessary
(see page 7).
2
Use the fine tuner to select the new
fundamental tone.
Adjusting the fundamental tone higher to G2 produces a range from G2-E3
G2 Fundamental
Adjusting the fundamental tone lower to E2 produces a range from E2-C3
E2 Fundamental
The total available range to select from is an octave, E2-E3.

Changing the fundamental will change the accuracy of the tuning gauge.

If the adjusted fundamental is necessary for an extended period of time,
reset the letters of the gauge.
If the adjusted fundamental is necessary for a short period of time, make
changes to the gauge letters as necessary.
