1. DESCRIPTION OF THE V 110 SE
Following the phenomenal international success of the flagship Octave V 80 SE integrated
amplifier, it was logical for the company to utilize the
O ctave D ynamic T echnologies ( ODT ) in the
further development of the popular V 110 model. The ODT concepts were first realized in the
Jubilee Mono SE, and subsequently incorporated into the MRE 220 mono power amplifier. The
performance of the MRE 220 benefited tremendously from the new technologies, which Octave
next implemented into its integrated amplifier range by also featuring ODT in the new V 80 SE.
Now, the next most powerful integrated amplifier of the Octave model range benefits from the many
years of experience and continuous development as the V 110 model goes into its second stage of
evolution. After all, the V 110 SE not only comes with the new Octave Dynamic Technology (ODT),
but it also offers even the unique opportunity of a "damping factor tuning". (See chap. 6.2.)
ODT Electronic
Essentially, looking to the technical aspects of ODT it is all about very high dynamic output power.
Therefore the newly developed KT 120 or KT 150 power tubes are featured in these models.
Together with the revised power supply and new output transformers we practically achieve a
doubling of peak output power compared to conventional push-pull amplifiers. The driver stage,
which drives the output tubes while also monitoring them, is completely updated and comes a huge
step closer to the ideal of the push-pull principle. The much-misunderstood negative feedback does
its job extremely well without having any influence on the acoustic side. The new amplifier
generation impresses with extreme linearity, significantly increased stability and downright
negligible noise and hum. Therefore all the ODT equipped Octave models are even more
independent from the selected loudspeaker and always exhibit - unaffected by the load - the same
high performance level. The precise tonal balance is maintained even at extreme levels.
Special features 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.
Damping Factor Tuning
The new V 110 SE is the first model in the Octave range which offers another feature: the
capability to optimally mate the amplifier to any loudspeaker regardless of its design principle. The
damping factor of the V 110 SE can be set to three levels (LOW, MED and HIGH), allowing the
amp to thus achieve a more precise adjustment to the electrical load of the speaker than ever
before possible. This itself is unique in the world and, as always with Octave, simple to accomplish
Thanks to a specially developed circuit design for this application the different settings can be
easily realized by exchanging the input tube. Tubes with a different gain are used. The enormous
range of usable feedback makes this "amplification / attenuation factor" Tuning possible. Octave
supplies the V 110 SE with two additional input tubes to enable this fine tuning
