Page 5: Foreword
FOREWORD FOREWORD Dear Music Enthusiast, You have chosen a modular OCTAVE model that you can customize with different op- tional slide-in modules. Thank you for choosing this flexible solution from our product range and for your trust. A variety of different input modules are available for your amplifier, both for the phono stage and additional line-level inputs. -
Page 6: Safety Instructions
Service and maintenance For reasons of safety, please ensure that servicing, repairs and other modifications to OCTAVE equipment are carried out only by a qualified technician. Defective fuses should also only be replaced by a qualified technician. Always replace fuses with ones of the same type and rating. -
Page 7: Warranty
MODULE OVERVIEW – PHONO INPUT MODULES Warranty OCTAVE can only guarantee the safety, reliability and performance of this unit if modifi- cations and repairs are carried out by specialized personnel and if the amplifier is oper- ated in accordance with the instructions contained in this manual. -

Page 12: In 2 Technical Data
MODULE OVERVIEW – PHONO INPUT MODULES 1. Please see the technical data or the pickup cartridge system’s owner’s manual for the recommended impedance. 2. Set the recommended input impedance according to the following table. If the rec- ommended input impedance is not listed in the table, use the closest value. If two values are possible, you can select the optimal impedance using a listening test. -
