3.1 Inserting or replacing the
batteries
The A-37 can be powered either by batteries or an
AC adaptor.
Battery replacement
Six AA batteries are required to run the A-37 on bat-
tery power. We recommend the use of alkaline bat-
teries because they will provide a more stable, long-
lasting source of power. With alkaline batteries, you
can expect about 25 hours of continuous operation,
although this depends on how the A-37 is being
used.
Note: Avoid using new batteries together with old
ones. In addition, avoid mixing different types of bat-
teries (e.g. regular carbon and alkaline batteries).
Note: When replacing batteries, be sure to insert them
correctly (ensure correct polarity).
Note: Remove the batteries whenever the A-37 is to
remain unused for an extended period of time.
(1) Switch off the A-37.
(2) Remove the battery cover located on the bottom of
the instrument.
(3) Take out the battery case, then insert the six batter-
ies supplied with the A-37 (three on either side).
(4) Insert the battery case and close the battery cover.
3.2 Connecting an optional AC
adaptor
Be sure to use only the specified AC adaptor (Roland
ACA series). Using any other type may cause mal-
function or electric shock.
Note: If the A-37 is to remain unused for an extended
period of time, unplug the adaptor.
(1) Switch off the A-37.
(2) First connect the AC adaptor to the A-37’s DC IN
socket, then connect the large plug to a power out-
let.
3.3 Connecting the A-37
Note: Switch off both the A-37 and the external
instrument(s) before establishing or breaking the MIDI
connections.
The A-37 is a MIDI controller. It contains no sound-
generating circuits of its own. You need to connect
it to at least one external MIDI instrument in order
to hear what you are playing. Here are the basic
connections:
Note: Do not forget to connect the module, synthe-
sizer, etc., to an amplifier. See its manual for details.

ward.
