E-drum Digital Percussion Module – Owners Manual

1. OVERVIEW

The E-drum digital percussion module is an electronic drum using sounds that are
digitally recorded and stored in easily interchangeable ROM cartridges. The module
allows you to control the loudness of the sound and (if desired) it’s pitch by how hard
you hit the pad. The pads sensitivity can be adjusted for playing styles ranging from
light finger taps to heavy sticking.

The module provides controls for tuning the original sound over the range of one
octave, setting the pads sensitivity for pitch change, adjusting the decay of the
sound and adjusting the bass and treble content of the sound. The rear panel
provides connectors for audio output, an optional AC power adapter and a multi
purpose control input that allows the module to be triggered from synthesizer gates
and triggers or audio signals (with level detection). This input also makes possible
independent voltage control of pitch via an active voltage pedal or other DC voltage
source.

The E-drum is powered by two 9-volt batteries or an optional AC adapter.

2. SETUP

POWER

The first step in setting up your E-drum module is to supply it with power. It may be
powered either by two 9-volt batteries (alkaline batteries are highly recommended)
or by an optional AC adapter.

BATTERIES
To install batteries, remove the battery compartment cover by loosening the
retaining screw on the bottom of the module. Attach a battery connector to the
terminals of each battery. Carefully stuff the batteries into the battery compartment,
being careful not to crimp or pinch any wires. Replace the battery cover and secure
with the retaining screw.

AC ADAPTER
IMPORTANT: Do not use any AC adapter other than the one supplied by E-mu
Systems specifically for use with E-drum modules.

To connect an AC adapter, insert the adapters mini phone plug into the AC IN jack
on the rear of the E-drum module. Plug the adapter into a standard 110 VAC outlet.
The power on LED should light to indicate the module receiving power.

POWERING MULTIPLE MODULES
Up to five E-drum modules can be powered from one AC adapter. For each
additional module you will need a patch cord with a 3.5mm phone plug on each end.
Plug one end of the cord into the AC out jack of a powered module. Plug the other
end into the AC in jack of the nearest un-powered module. This module can now be
connected to another and that to another etc.

Do NOT connect more than five modules to a single AC adapter.
