Operation Manual

BACK PANEL:
WARNING: This amplier must be earthed. Please check that the supply voltage details given on the
rating label (located on the rear panel) are in accordance with your electricity supply.
1 MAINSINPUT: This is the input socket into which the mains power cable must be connected. This
amplier is supplied with a power cable with a moulded-on plug. If the socket outlets in the home are not
suitable for this plug, use an appropriate plug adapter that can handle the power required for the amplier.
2 POWERFUSE: In the event of the power fuse having to be replaced, rst unplug the power cable
from the mains outlet. Then remove the fuse cover and replace the power fuse with another fuse of the
same type and value. Never plug the power cable back into the mains outlet without the fuse cover. If the
power fuse blows up again when powering on the amplier, take the apparatus to a suitable service centre
for repair.
3 CD/MP3INPUT: This is a line level 1/8” (Ø 3.5 mm) mini stereo jack into which an MP3/CD/Tape
player may be connected.
4 HEADPHONES This is a 1/4” (Ø 6.3 mm) standard jack output to connect the headphones. When
headphones are connected, no sound is produced from the speaker.
5 DRUMSINPUT: Plug your electronic drums in here, using the Left and Right 1/4” (Ø 6.3 mm) jack
inputs for stereo sound sources, or the Left input alone for mono sound sources. We recommend that
you always use a high-quality shielded cable to prevent any background noise interference or unwanted
feedback.
6 AUXILIARYINPUT: Here you can plug in any other instrument using a 1/4” (Ø 6.3 mm) mono jack
input. Again, we recommend that you always use a high-quality shielded cable to prevent any background
noise interference or unwanted feedback.
PLEASENOTE: Drum amplifying can prove complicated, because the sounds involved range from bass-
heavy kick drum to high-pitched cymbals. It is therefore possible that you may have to use different
settings depending on the type of music you play. Remember that the EDA-40 is designed primarily as an
indoor amp.

FRONT PANEL:
1 AUXILIARYVOLUME: This control determines the output volume for the auxiliary channel.
2 DRUMGAIN: This control determines the gain level for the drum channel.
3 DRUMCOMPRESSION: This control reduces the dynamic range of the output signal and evens out
the changes in volume that occur according to how hard you hit your electronic drums. Adding compression
will make your electronic drums sound smoother and clearer and avoid unnecessary distortion.
4 TREBLE: This control determines the level of high frequencies in the output signal. Adding treble will
make the drums sound brighter and sharper.
5 MIDDLE: This control determines the level of middle frequencies in the output signal. Adding mid will
make your drums sound rounder and fuller.
6 PARAMETRICMIDDLE: Parametric mid is a more sophisticated way of boosting or cutting middle
frequencies. In a traditional EQ, the frequency area that is boosted or cut is xed. With a parametric mid
EQ, this frequency area is adjustable from mid low to mid high. Use this knob to select the required range
of middles, then use knob # 5. to determine the level of the selected range of mid frequencies.
7 BASS: This control determines the level of low frequencies in the output signal. Adding bass will make
your drums sound warmer and heavier.
8 MASTER: This control determines the overall volume of the amplier.
9 POWER: This switch turns the amplier on or off. The switch is lit up when the amp is powered on.
