1. The first step is to provide your module with power The module only re quires stabilized 12v amp 12v voltages These voltage should already be provided by your modular system power supply Please connect the supplied 16 way ribbon cable to the module Eurorack bus connector 28 and your modular system bus board Figure 3 A 100 BUS BOARD version 5 JGATE GATE JCU CU J BU 5U 12U MEAT GND GND J6ND En 16ND SA 12U s q I 42U Figure 3 Eurorack bus connector Eurorack connectors are usually orientated so the Gate signal is on top and the 72v supply at the bottom Refer to Figure 3 The NW1 module follows the same convention Please make sure the ribbon cable does not swap the lines 14 5 2 Audio connection 5 DEVICE CONNECTION The module can now be installed in the rack using the provided screws washers and a Phillips head screwdriver 0 With the module installed switch the system power supply on The module Display 25 will show a short animation followed by the selected wavetable number 5 2 Audio connection The second step is connecting the audio output of the module so you can hear the sound A mixing desk or an audio amplifier system should be at tached to the Audio output 6 of the module It is essential to use some volume attenuation before power amplification The NW1 output level is rather high up to 16v peak peak compared to line audio standard Connecti2. http www waldorfmusic de nwi overview html e Product development team NW1 team e Development Oliver Rockstedt Fr d ric Meslin Isabelle Kernhof Stefan Stenzel Frank Schneider e Design Stefan Stenzel Axel Hartmann e Testers Dirk Krause Juergen Driessen Rolf Woehrman Tom Wies e Manual Fr d ric Meslin Stefan Stenzel Revision 1 0 September 2015 We would like to thank Joachim Flor Willie Eckl Michael von Garnier Christian Bacaj Karsten Dubsch Daniel Krawietz Kurt Lu Wangard Echo Wu Miroslaw Mirek Pindus Erik Norlander Stephan Gries CONTENTS Contents R General safety guidelines Device maintenance Package contents Device overview 4 1 Frontpanel 4 2 Backpanel Device connection 5 1 Power connection 5 2 Audio connection Playing back wavetables 6 1 Wavetables basics 6 2 Choosing a wavetable 6 3 Scanning wavetables 6 4 Tuning the oscillator 6 5 Transforming the sound 6 6 Modulating the sound Recording wavetables 7 1 Recording basics 7 2 Recordingsetup 7 3 Recording awavetable 7 3 1 Choosingaslot 7 3 2 Audio source and gain 7 3 3 Prepare recording 7 3 4 Arming the recorder 7 3 5 Recording 7 4 Advanced options 7 4 1 Compression level 7 4 2 Playback quality Transferring wavetables Speech wavetables CONTENTS CONTENTS 10
