Trigger Placement; Bass Drum; Snare Drum - Alesis D4 Quick Setup Manual

triggering. Most of the trigger manufacturers supply several
pieces of mounting tape with their trigger products. It is also
very important to be certain that no part of the trigger wire,
which connects the trigger to the audio jack, is touching or
resting on any part of the drum or rim. This wire is sensitive
enough to trigger signals from the drum vibrations which
would then cause double triggering.
Trigger Placement
Placement is another very important part of triggering
performance, but unfortunately there is no right or wrong set of
rules. It simply takes a lot of experimentation to arrive at the
correct combination for the type and size of drum, and the drum
kit configuration you are using. These tips will help you get
started with a step in the right direction.
BASS DRUM
1. Mount the trigger directly on the impact head.
2. Place the trigger approximately 2-4 inches in from the rim,
and level with the beater.
3. Slightly reduce the sensitivity of the trigger if it has an
adjustment.
SNARE DRUM
If you play with a fairly tight batter head, try this:
1.. Mount the trigger on the batter head.
2. Place the trigger approximately one inch from the rim, on the
opposite side of the drum from the player.
3. Slightly reduce the sensitivity of the trigger if it has an
adjustment.
If you play with a looser head, try this:
1. Firmly mount the trigger to the shell approximately one-half
inch from the batter rim.
2. Placement of the trigger should be on the players side of the
drum, within a lug or two of where the stick would hit if you
plaved a rimshot.
