MIDI I/O. Two 5-pin DIN connectors provide MIDI input and output.
Hook. Secure any loose cable by feeding it through the hook first.
Power . The included hi-performance switch mode power supply oper-
ates in the range of 100V to 240V AC at highest power efficiency. It is
short-circuit-proof, has an integrated line filter, is fully regulated
against voltage fluctuations, suppresses mains interference, and of-
fers hum-free operation. It supplies 12 V DC at up to 2 A with the cen-
ter pin + and outer pin GND.
The connector at the power supply and the socket at the unit come
with a
turn to lock feature. When inserting the connector make
sure the little wings are aligned correctly so that the connector is
fully inserted
. Then turn the connector so that it is locked and can no
longer be removed. If not fully inserted the connection will be loose
and cause power loss when the cable is moved.
