  • Page 3: Getting Started

    Getting Started Connecting: On the right end panel of your LD3, you will find the power switch, connection for power supply, stereo audio outputs, USB, and MIDI in and out. You would probably like to connect the audio outputs to a mixer or an amplifier, or anything else that ends out in a speaker/a set of speakers.
  • Page 4 playable sounds. It is also possible to connect anything that transmits a MIDI clock, if you would like the sequencer of LD3 to sync to the rest of your setup. On MIDI out, MIDI clock, MIDI CC’s from the LD3 edit knobs, and notes and CC’s from its sequencer are transmitted.
  • Page 5 On the left end panel of your LD3, you will find the stereo audio inputs. The optional extra audio inputs and outputs and the CV inputs and outputs are also found here, if installed. Audio inputs L and R The two rightmost 1/4” jack connectors, marked “AUDIO IN R L” are always the stereo audio inputs.
  • Page 6 When 4 extra audio inputs and 4 extra audio outputs were ordered: This option were only available at pre-ordering. The tip of AUDIO IN/OUT 3, 4, 5 and 6 are audio inputs 3 to 6, the ring of AUDIO IN/OUT 3, 4, 5 and 6 are audio outputs 3 to 6.
  • Page 7 Starting Up Connect the supplied power adaptor to the Power input, and to a 100V to 240V power source – Usually a wall socket. It’s a 9V, minimum 2.0A type with a 2.1 mm DC plug, with positive middle. The powersupply on the picture is only for reference.
