[. . . ] C Kettle edge Counter Collar hoop Kettle edge Counter Collar hoop If the collar is not uniform (illustration titled "Wrong"), keep the heel of the pedal fully depressed as shown in Fig. C, and align head and hoop as shown in the illustration titled "Correct". 2 Make sure that the end of the wire tube is not disengaged from the adjuster of the tuning indicator as shown in Fig. Hold the pedal in this position, as it will return otherwise. 4 Before Using The Pedal Timpani 5 Using the supplied timpani key, tighten the tuning bolts by 1/4 of a turn (90°) in the order shown below. It is very important to always turn all tuning bolts by the same amount. 9 Tighten each tuning bolt by 1/8 of a turn (45°) in the order shown in step 5. 10 G Toe and heel feel equal Timpani key ¡ Go to step 11 G Heel still feels heavier than toe ¡ Repeat steps 8 through 10 G Heel feels lighter than toe ¡ Head is tightened too much. [. . . ] G If the heel of the pedal moves downward ¡ Head is tightened too much. Loosen the head as described in step 7. 7 Put your foot on the pedal and fully depress it in either direction (toe and heel). Keeping the heel of the pedal depressed, loosen the first tuning bolt by 1/ 2 turn and then retighten it by 1/4 of a turn. Perform this operation for all other tuning bolts in the order shown in step 5. If necessary, repeat this procedure, until proper tension is obtained. 12 Strike the head lightly with the supplied mallet etc. The standard striking point is shown below. The standard striking point lies at distance B from the kettle edge, which corresponds to 1/4 to 1/3 of distance A (distance between kettle edge and center of head). Striking point Pedal 8 Fully depress the heel of the pedal as shown in Fig. For details on precise tuning refer to "Adjusting The Sound Of Your Timpani" on the following page. Note As the head will stretch over time, readjustment should be performed periodically (starting with step 7 ) 5 Adjusting The Sound Of Your Timpani When using the pedal timpani for the first time after unpacking, make sure to set it up according to the instructions of section "Before Using The Pedal Timpani" on pages 4 and 5. z Head Tuning* (* Adjusting the head tension to a specific note) When loosening the tuning bolts, always loosen them by double the desired amount, and then return (retighten) them by half. When the sound lies within 1 halftone below the desired pitch after loosening the tuning bolts (repeatedly, if necessary), proceed with step 3. 1 Tuning is performed for the lowest sound (note) of the timpani. For this reason, the heel of the pedal must stay fully lowered during the tuning procedure. The proper lowest note (and tonal range) depends on the size of your timpani. For example, as shown in the figure below, the lowest sound of a 26" timpani should be tuned to A. After adjustment, securely tighten the pointer lock nut. 1 After you have tuned your timpani to the lowest note of its tonal range, make sure that the pointer is located within 10 mm from the pedal-side end of the indicator rail. * If not, adjust referring to "Adjusting the Pointer Position". Slide the lowest note of the indicator ("A" in case of a 26" timpani -- see "Standard Tonal Ranges for Yamaha Timpani" on page 6) to the position where its center line coincides with the pointer. Tune the instrument to the next higher pitch (note) by moving the pedal, and then slide the corresponding note on the rail to the respective pointer position. Repeat for each note. 2 3 * The tuning indicator can be set to a desired angle by loosening the indicator mounting screw using a Phillips screwdriver. Indicator rail Pointer Indicator rail Note Pointer Note Adjuster Adjustment nut 8 Other Features I Pedal Adjustment Clutch Using the PAC, you can adjust the rotational torque of the pedal to a comfortable pedal force without degrading the smooth pedal action. In addition, the PAC is useful in preventing undesirable happenings such as slight movement of the pedal when the head is struck strongly causing a small change in pitch. G PAC Adjustment Use the timpani key to turn the PAC adjustment bolt as follows: Turn the PAC adjustment bolt to the right (clockwise) to tighten the pedal movement. To return the tightened pedal movement to the initial rotational torque setting, turn the PAC adjustment bolt to the left (counterclockwise). The TP-50xx (H/G) / TP-70xx (H) series use a wing bolt on the PAC adjustment system. Note on PAC Usage PAC adjustment bolt The PAC (Pedal Adjustment Clutch) is an original Yamaha mechanism that enables you to adjust the pedal's rotational torque (the force required to move the pedal) by altering the amount of friction within the pedal balance spring mechanism. · The pedal cannot be locked with the PAC, even at its tightest position. (Do not try to use the PAC for locking the pedal, for example to prevent the toe of the pedal from jumping up when the head is removed. ) · The PAC adjustment bolt has limit positions in both turning directions. If the bolt is hard to turn, do not force to overtighten it because this may cause damage to the mechanism. 9 Moving And Setup Your Timpani The timpani can easily be moved when the third wheel is attached to the pedal section as shown on the right. When using a Yamaha timpani head, its YAMAHA logo must be on the side opposite the pedal. [. . . ] The hoop must be re-mounted in the same position as marked with cellophane tape in step 2. Tighten the tuning bolts alternately by hand until the head is tensioned slightly. At this time, make sure that head and hoop are centered on the kettle. Tighten each tuning bolt an additional 1/4 of a turn using the timpani key. [. . . ]
