    (On new units, both of these switches are set to "off" at the factory). Now switch the V 80 SE on using the amplifier’s power on/off switch. 2 or 4 LEDs will illuminate, depending on the position of the switch. The soft-start LED will illumi- nate.

The volume of a multichannel system is normally controlled digitally by the receiver/processor preamplifier. Please ensure therefore that your multichannel unit is switched on and that its volume setting is not too high when you activate the "Front Channel"...

  • Page 23: Linear Mode

    In Linear mode, the power amplifier section of the V 80 SE is connected to the internal preamplifier and to the input selector switch. This is the V 80 SE's normal operating mode – as an integrated amplifier. The mode selector [8] must be on Linear.

  • Page 24: Inserting An External Equalizer

    Connect the preamplifier to Master In, with the mode selector knob [8] in the Extern position. In this mode, you retain the use of the V 80 SE's volume control. When using this option, you should generally set the volume control on the V 80 SE to maximum and adjust the volume with the external preamplifier.

  • Page 25: Adjustable Preamplifier Output: Pre Out

    Pre Out may prove to be a problem. The best way to deal with this is to make sure you switch the V 80 SE on before the external power amplifier and then switch the units off in reverse order.

  • Page 26: Ecomode: Soft-Start And Reduced Power Consumption Mode

    V 80 SE is ready for use. Note: If you switch the V 80 SE on with Ecomode active, it will go through the restart procedure. If it fails to detect a music signal, it will shut down after 10 minutes.

    7. ADVANCED FUNCTIONS As well as saving electricity, Ecomode has a number of other advantages. longer tube life  reduced heating of the whole unit  increased passive safety if the unit is left on by mistake  Ecomode is not the same as standby, however, because certain sections of the amplifier remain the tape loop (you can still make recordings, as described in Chapter 6.6) ...

Note 2 If you try to use the on/off switch to switch the V 80 SE on when the headphone switch in position C (headphones only) and the Ecomode switch in position B (Ecomode ON), the tube power amplifier section will not power up.

  • Page 29: Power Selector: Alternative Output Tubes

    The Power Selector allows adjusting the V 80 SE in accordance to the output tubes. Position HIGH is reserved for the standard KT150 tubes as well as the KT120. In the HIGH Position the V 80 SE is able to deliver up to 2 x 130 W RMS Output Power. The slightly weaker tubes type KT 88 or 6550 can be used in the position LOW.

  • Page 30: Tubes

    Note: Low Power tubes will not allow you to achieve the maximum output of the V 80 SE. We do not recommend using them in the V 80 SE Some tubes will fit into the sockets but will still not work with the V 80 SE – the EL 509 / 519, for example.

  • Page 31: Bias Measurement System

    That is why we have built this bias measurement facility into the V 80 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 an accuracy of 0.3%, making it superior to any...
  • Page 32 8. 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 33: Replacing Tubes

    You should adjust these tubes after about 20 minutes. 8.5. Running in tubes 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.

  • Page 34: Protection System

     Once the protection system has cut in, the only way you can turn the V 80 SE back on is to turn the on/off switch off and then on again. Allow the unit two minutes to cool down before switching it back on.

    11. OPTION PHONO MC / MM A phono MM or MC board is available as an option for the V 80 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 36: Option Black Box And Super Black Box

    OCTAVE, with the Black Box technology, offers an instrument to 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 37: The Super Black Box Option

    V 80 SE is powered down with Ecomode on. The Super Black Box is equipped with a rapid discharge circuit, which discharges the unit's electrolytic. The yellow LED indicates that this procedure is taking place.

    DACs. Although the V 80 SE is grounded, its signal ground is a "floating" ground, which means that the V 80 SE cannot create ground loops itself. Hum can only be caused when it is connected to other items of equipment.

  • Page 39: Mains Interference

    To reduce this kind of interference, move the transformer/component or the affected component/cable to a different location. The transformer in the V 80 SE will not generate interference, as it is electromagnetically shielded and has a very low stray field.

  • Page 40: Faults Caused By Tubes

    13.2. Faults caused by tubes, faulty tubes Like other OCTAVE products, the V 80 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 41: Tube Faults That Trip The Protection System

    "front" the particular tube is, the more it will tend to make itself felt. In the V 80 SE, this would be tube V 6. 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.

  • Page 46: Frequently Asked Questions (Faq)

    Does the V 80 SE have to have all of its tubes fitted? In principle, the V 80 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.
