Rogers DYNA-SONIC Manual

TUNING YOUR ROGERS DYNA-SONIC SNARE DRUM
Unlike conventional snare drums, your Dyna-Sonic
snare drum is a uniquely-engineered and highly sensi-
tive instrument. The floating snare assembly provides
super-reactive snare response at all levels of touch - from
a whisper, to full thrust play. With both heads tuned well,
the Dyna-Sonic snare drum will deliver the full-bodied
tone & unprecedented dynamic response that have made
it the most sought after drum since its introduction in 1961.
1. Use even tensioning: Loosen all tension screws
(using half turns at a time) in a sequence pattern (Fig. 1)
until all tension on the head is relieved. Then re-tighten all
tension screws (again in sequence) with fingers or drum
key until the screw head collar contacts the hoop sur-
face. This will level the hoop and head evenly against the
bearing edge of the shell, and puts the head 90% in tune.
2. For the top (batter) head: turn each tension screw in
sequence with a drum key in one half turns. Repeat this
sequence until you have completed four half turns total.
3. For the bottom (snare) head: using the same proce-
dure described above, turn each tension screw with the
drum key - but this time a total of five equal half turns.
4. (Fig. 2) Using your fingers, tighten the adjuster screw
on the snare frame end (A) only to the point where the
tension stops the snares from rattling (a small
adjustment) Do not use a screwdriver, or over-tighten.
5. (Fig. 3) The snare frame (B) should be cen-
tered inside both of the snare "gates" (C) on the
bottom hoop. With strainer lever to the "ON" position,
check that both the strainer end and butt end of the
snare frame sit centered inside the gates of the hoop.
6. (Fig. 4) With the strainer lever ON, turn the snare
strainer knob (D) counter clock-wise until the snares
are loose (no snare rattle when drum is tapped).
Now, turn snare strainer knob clockwise until the
loose snare rattle disappears and drum sounds crisp
when tapped with a drum stick. NOTE: the high
sensitivity of the Dyna-Sonic snare frame system
produces reactive snare response at all dynamic
levels, and can be tweaked to suit personal preference.
7. As a final check, tap lightly with a drumstick one
inch in from the edge to check approximate pitch at
each tension screw (Fig. 5) If any one tension screw
sounds higher than the others, loosen it ¼ turn. If any
one tension rod screw sounds lower, tighten it ¼ turn.
