Page 4: Octave Technology
1.1. Characteristics of the OCTAVE tube technology Sound The design goal of OCTAVE amplifiers is honest, natural sound reproduction. The sound characteristics of an amplifier are derived from the sum of all its parts. Tubes themselves do not guarantee high quality sound. -
Page 5: Phono Module Description
Therefore additional electronic systems are required to achieve these benefits without any drawbacks. A particularly unique option of the Octave Phono Module is the Line Input module. Adding this module provides the unit with line level functionality allowing the connection of a high level source via either single-ended (RCA) or balanced (XLR) inputs. -
Page 6: Safety Instructions
Defective fuses should also only be replaced by a qualified technician. Always replace fuses with ones of the same type and rating. If your amplifier requires servicing, please ship or take your equipment directly to OCTAVE or to one of our authorized service centers. -

4. MAIN UNIT 4.6. Tube layout, replacing tubes Tube Layout: ECC88 ECC81 ECC83 Tube (ECC83, 12AX7) is the Input Tube. Please use Low Noise Tubes of high quality with matched systems. Tube (ECC81, 12AT7) is for the Main Amplification Stage. Tube (ECC88, 6922, 6N23, 6N1,) is for the Output Buffer. -
Page 15: Subsonic Filter
4. MAIN UNIT 4.7. Subsonic Filter Subsonic Filter Uneven records and mismatched cartridge – tonearm combinations can result in low frequency signals in the range below 15 Hz (addi- tional to the music reproduction). Signals of this low frequency cause excessive swing of the bass driver membrane, especially if it’s a bass- slide switch rexlex system. - Page 16 4. MAIN UNIT 4.7. Subsonic Filter Frequency Response of the Phono Module ( RIAA Curve ) with and without Subsonic Filter: Flat Graph, Fre- quency Response without Subsonic Filter Descending Graph, Frequency Response with Subsonic Filter Low Frequency Signals below 20 Hz will be reduced through the Subsonic Filter by 12 dB / Octave.

Page 17: Options
5.1. Option Remote Control (when used as a preamplifier) Of course it is also possible to use the Phono Module with the output modules OUT2 or OUT3 as a preamplifier and to connect it directly to the power amplifier. In this case it is helpful to have a remote control available for volume control. -
Page 18: Option Black Box Preamp
5.2. Option Black Box Preamp Description An external upgrade of the power supply of the Octave Phono Module, the Black Box Preamp fea- tures a sophisticated circuit with superior capacitors (produced in the EU and sourced from EPCOS), and serves to increase the current flow while making the power supply immune to mains power fluctuations. -
Page 19: Available In- And Outputs
See separate operating instructions "Input and output modules". in the cover sheet of this instruction manual. The modular structure of the new phono module enables a multitude of possibilities on both the input and output side, which leave nothing to be desired for both phono and high-level listeners. Different line and phono input modules are available up to the step-up transformer and 3 output modules. -

Such a device has no adverse affect on the sound or picture quality of tuners or TVs. The Phono Module is not grounded and therefore cannot cause ground loops. Clicks and pops Older fridges and 12 V halogen lamps can cause cracking through the loudspeakers when they are switched on and off. -
