AUDIO OUTPUT
Using a patch cord with a standard ¼” phone plug, connect the E-drum modules
audio output to your amplifier or other sound system. Start with your amplifiers
volume at a low setting until you become familiar with the E-drums output level.
SOUND CARTRIDGE
Select an E-drum sound cartridge and insert it into the slot at the rear of the E-drum.
The cartridge should be inserted such that the label is readable from the top. (The
cartridge is keyed so that it will only go in the right way.) Be sure the cartridge is fully
and securely inserted into the module. If it doesn’t seem to want to go in, try pushing
it to the left (as seen from the rear of the module) and then in.
POWER ON
(Pay close attention to this section or you may find yourself buying a lot of batteries!)
If you look carefully at the labeling on the E-drum module, you will see that what you
were thinking was the “power on” button was actually called the “Batt. On” button.
This button controls the battery power for the module. When it’s in the “in” position,
the batteries are powering the module. When it’s in the ”out” position, the batteries
are disconnected from the circuit. If you are using only the batteries, you can simply
consider this the on/off button.
However, if you are also using an AC adapter, things get a bit tricky. Unlike some
other products that you may be familiar with, plugging in the AC adapter does not
automatically disconnect the batteries. Only having the BATT. ON button in the off
position will disconnect them. It is therefore possible to have the AC adapter
plugged in and still be draining the batteries. When using the AC adapter always
check to see the battery switch is in the “off” position. (When using the AC adapter,
there is no on/off switch. The module is on as long as the adapter is plugged in. Be
sure to unplug the adapter from the AC outlet when you are through playing.)
SELECT SOUND
Some E-drum sound cartridges contain two sounds. Pressing the sound select
button on the E-drum modules front panel will let you choose between these
sounds. This button will have no effect on a single sound cartridge. (Some E-drum
modules have two sound select buttons. Simply ignore the right button.)
3. CONTROLS
PAD SENSITIVITY
The sensitivity of the E-drum modules pad can be adjusted using the 15-turn
trimmer accessible through the small hole to the right of the pitch knob. To adjust
the trimmer you will need a small screwdriver or a trimmer adjustment tool (available
at most electronic stores like radio shack). Turning the trimmer counterclockwise will
decrease the sensitivity (i.e. you will need to hit the pad harder). Turning the trimmer
clockwise will increase sensitivity. Remember, you have to turn the trimmer 15 times
to go from one end of the range to the other, so you will probably have to turn it a
couple of turns to notice any effect at all.
