28 EUROGRAND EG2280USB/EG8280USB User Manual
Appendix9.
Cables9.1
Below you will find an overview of all cables you need to connect your digital
piano. The cables are not supplied with the piano. Depending on the intended
use, adapter cables will be necessary to interface the various connectors. You can
use adapter cables or plugs (e.g. ¼" to RCA). Cable adapters are better than
adapter plugs, as the latter may affect the signal quality due to insufficient
contact of the plugs with each other.
Unbalanced ¼" cable9.1.1
Unbalanced ¼" cables are equipped with a ¼" TS plugs at each end. They are
used to connect external keyboard amps and devices with ¼" outputs
(e.g. synthesizers, drum computers) to the EG2280USB/EG8280USB.

RCA cables9.1.2
RCA cables are often used for hi-fi applications to connect CD players,
MD recorders and other devices to home stereo systems. You will need this type
of cable to connect the EG2280USB/EG8280USB to hi-fi recording equipment.
Usually, these cables are supplied in pairs to form one stereo cable. The plugs
are in most cases red (right) and white (left). Make sure that the wiring between
recording device and EG2280USB/EG8280USB follows this color code, so as not to
mix up the left/right signals.

¼" to RCA cable9.1.3
¼" to RCA cables are required for connecting a hi-fi playback device
(e.g. CD player) to the EG2280USB/EG8280USB. As an alternative, you can also use
an unbalanced ¼" cable with an appropriate RCA adapter.

MIDI cables9.1.4
MIDI cables are required for connecting MIDI equipment. These cables have a
5-pin DIN plug at each end. Be sure to use cables marked as MIDI cables (wiring as
shown), since there are also similar cables with a different wiring available for
hi-fi equipment. MIDI cable lengths should be as short as possible. Avoid cable
lengths exceeding 10 m, as these could lead to errors during the transmission
of signals.
