  • Page 6: Description Of The V 110 Se

    Power Pre Selector for alternate output tubes The V 110 SE is a member of the family of amplifiers, based on the power tube KT 120. A switch on the rear panel allows switching between different types of tubes, to ensure the operation in their optimum sonic performance and working conditions.

  • Page 7: Safety Instructions

    2. SAFETY INSTRUCTIONS 2.1. Before you begin Before using the V 110 SE for the first time, remove the grille and install the power tubes! (See Section 3.2 „Removing the grille"). Replace the grille before switching the V 110 SE on.

  • Page 8: Placement

    2.2. Placement 1. Location OCTAVE equipment is designed strictly for use in a dry domestic environment. Do not use it in the open air or in damp environments! Never place plants or liquid-filled containers on your OCTAVE equipment. Take care to avoid dropping objects or spilling liquids into the case.

  • Page 17: Advanced Functions And Connection Options

    The Power Selector allows adjusting the V 110 SE in accordance to the output tubes. Position HIGH is reserved for the standard KT 120 tubes. In the HIGH Position the V 110 SE is able to deliver up to 2 x 110 W RMS Output Power. The slightly weaker tubes type KT 88 or 6550 can be used in the position LOW.

  • Page 18: Changing The Damping Factor

    6.2. Changing the damping factor The V 110 SE is the first model in the Octave range that provides another tool, to match the ampli- fier with any speaker regardless of the construction principle .The V 110 SE allows to change the damping factor in three settings (LOW, MED and HIGH), and thus achieve an even more sensitive adjustment to the electrical load (speaker).

  • Page 19: Protection

    The BIAS LEDs will show "yellow" for each of the four output tubes. If a Black Box or a Super Black Box is connected to the V 110 SE, the front panel (operate) LED of the Black Box / Super Black Box will go out. If the Super Black Box is connected, tripping the protection system will automatically activate the discharge circuit of the (Super) Black Box (see chapter 10).

  • Page 20: Ecomode

    After 9 minutes without receiving signal, the V 110 SE Ecomode is activated, turning down the power. In this “sleep” mode, the V 110 SE draws less than 20 W Idle current. Therefore the running unit produces no heat, because the heater voltage and the high voltage for the power amplifier section are switched off.

  • Page 21: Front Channel

    “Front Channel” selector position, the V 110 SE functions as a stereo amplifier. The overall Gain of the V 110 SE is reduced to 26dB in this position. The signal of the front channel input is not available on the record output.

  • Page 22: Tubes

    Note: Low BIAS tubes will not allow you to achieve the maximum output of the V 110 SE. We do not recommend using them with low efficiency or low impedance loudspeakers. Some tubes will fit into the sockets but will still not work with the V 110 SE – such as the EL 509 / 519, for example.

  • Page 23: Bias Measurement System

    That is why we have built this BIAS measurement facility into the V 110 SE – to allow you, the user, to carry out the adjustment yourself without the need for test equipment. The use of precision op amps makes it possible for you to set the BIAS to accuracy within 0.3%, making it superior to any...
  • Page 24 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 25: Replacing The Tubes

    You should adjust these tubes after about 20 minutes 7.5. Running in All OCTAVE equipment is subject to a 48-hour soak test at the factory to burn in the tubes. The tubes are preselected for use in each particular model.

    9. PHONO (MC / MM) OPTION A MM or MC Phono board is available as an option for the V 110 SE. This additional board is connected internally to the phono input. When the board is installed, this input can no longer be used as a line level input.

  • Page 27: Using Black Box Or Super Black Box

    With the Black Box technology OCTAVE 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’...

Yellow unload LED The yellow “unload” LED (discharge control circuit) lights up for ap- proximately 2 seconds after switch-off, in case the electronic protec- tion is activated and if the amp is powered down through the Eco- mode.

    DACs. Although the V 110 SE is grounded, its signal ground is a "floating" ground, which means that the V 110 SE cannot itself create ground loops. Hum can only be caused when it is connected to other items of equipment.
  • Page 30 To reduce this kind of interference, move the transformer/component or the affected component/cable to a different location. The transformer in the V 110 SE will not generate interference, as it is electromagnetically shielded and has a very low stray field.

  • Page 31: Faults Caused By Tubes

    11.2. Faults caused by tubes, faulty tubes Like other OCTAVE products, the V 110 SE 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 32 "front" the particular tube is, the more it will tend to make itself felt. In the V 110 SE, this would be tube V 5. As it is rare for both systems in a double triode to be equally affected, the noise levels in each stereo channel will be different.

    Does the V 110 SE have to have all of its tubes fitted? In principle, the V 110 SE will also operate without tubes. It is sometimes useful to do this when testing the operation of the switching functions such as the selector switch, remote control, etc.
