Page 6: Description Of The V 110
1. DESCRIPTION OF THE V 110 The Octave V 110 integrated amplifier is a push-pull pentode design delivering 2 x 110 W RMS output power (into 4 ohm loads). As with all Octave models, all research and development (R&D) and production has been conducted exclusively in-house, and the amplifier is comprehensively safeguarded against user error and parts wear –... -
Page 7: Safety Instructions
Servicing and maintenance For reasons of safety, please ensure that any servicing, repairs or other modifications to OCTAVE equipment are carried out only by a qualified technician. Always get an engineer to replace blown fuses with ones of the same type and rating. -

6. ADVANCED FUNCTIONS 6.1. Power Selector, alternative output tubes Position „HIGH“: KT120 Position „LOW“: KT88, 6550, KT90, KT100 (EL34 with Restrictions) The Power Selector allows adjusting the V 110 in accordance to the output tubes. Position HIGH is reserved for the standard KT 120 tubes. In the HIGH Position the V 110 is able to deliver up to 2 x 110 W RMS Output Power. -
Page 18: Protection
6. ADVANCED FUNCTIONS 6.2. Protection The V 110 features a comprehensive electronic monitoring and protection system. This system will automatically switch off the V 110 if case of a fault occurring in the power section. The protection system has been designed to keep the unit safe from the consequences of overloads of any kind and to protect the output tubes from current surges. -
Page 19: Ecomode
6. ADVANCED FUNCTIONS 6.4. Ecomode The Ecomode serves to reduce heat and unnecessary power consumption when the unit is switched on but not in use. After 9 minutes without receiving signal, the V 110 Ecomode is activated, turning down the power. In this “sleep” mode, the V 110 draws less than 20 W Idle current. -
Page 20: Front Channel
6. ADVANCED FUNCTIONS 6.5. Front Channel Input - Bypass function The Input labeled “Front Channel“ is coupled with a relay that bypasses the volume regulator. In the “Front Channel” selector position, the V 110 functions as a stereo amplifier. The overall Gain of the V 110 is reduced to 26dB in this position. -

Page 22: Bias Measurement System
7. TUBES 7.3. THE BIAS MEASUREMENT SYSTEM The BIAS measurement facility makes it easy for you to check and adjust the idle current of the output tubes. Getting the BIAS setting right for all four tubes is critical for both the sound of the power amplifier section and for the service life of the tubes. - Page 23 7. TUBES There is an upper adjustment limit to the "high" BIAS setting, which is indicated by the green and red LEDs lighting up at the same time, and a lower limit to the "low setting, where the yellow and green LEDs light up.

Page 26: Using Black Box Or Super Black Box
OCTAVE, with the Black Box technology, offers an instrument for optimizing the OCTAVE amplifier in respect to the speaker. This flexibility is a unique feature of the OCTAVE brand. The dynamic and tonal stability of an amplifier is strongly dependent upon the stability and capacity of the power supply, therefore the Black Box and Super Black Box were developed as external upgrades to the OCTAVE amplifiers’... -

Page 28: Troubleshooting
11. TROUBLESHOOTING 11.1. Faults caused by external issues Buzzing and hum in the speakers Possible cause: multiple grounds Hum in an audio system is often caused by several system components having their own separate grounds. It is particularly common in systems containing tuners, VCRs or satellite receivers, as these components are connected to an aerial. - Page 29 11. TROUBLESHOOTING Possible cause: induction Another possible cause of hum could be the stray field of a transformer generating interference in a device or cable. You can easily diagnose this problem by switching off the problem component. To fix the problem To reduce this kind of interference, move the transformer/component or the affected component/cable to a different location.

Page 30: Faults Caused By Tubes
11.2. Faults caused by tubes, faulty tubes Like other OCTAVE products, the V 110 is equipped with a double safety system. This means that the amplifier will be protected from damage if a component (tube) should fail and trip the electronic protection. - Page 31 11. TROUBLESHOOTING Tube faults that trip the protection system The protection system continuously measures the current flowing into the four power tubes. Depending on the problem, this current may exceed a specified limit and cause the protection system to switch the power stage off. The red protection LED will light up to show that this has happened.

Page 35: Frequently Asked Questions (Faq)
Can you operate the V 110 when no loudspeakers are connected? Yes. The V 110, like all OCTAVE amplifiers, is fully protected against open circuit operation, i.e. the amplifier will come to no harm if it is operated without loudspeakers connected. - Page 36 We reserve the right to alter and improve the specifications in pursuit of better.
