1. DESCRIPTION V 80 SE
The V 80 SE is a totally new design. It has been developed for music
lovers who do not have the space for large pre- and power amps. The
V 80 SE is guaranteed to provide the same sonic experience as
separates. Nevertheless, as a standalone unit, it is equipped with ever
y
feature you could need no matter how your hi-fi system is configured. We
have also included a number of forward-thinking features that are unique
in this amplifier class.
POWER AMPLIFIER +
BIAS
The power amplifier is a push-pull pentode system producing up to 130
W RMS each channel from 20 Hz to 80 kHz. The amplifier was designed
specifically for the V 80 SE, although its concept borrows heavily from
the MRE 220. This power amplifier enjoys excellent load stability, i.e.
neither the impedance nor the efficiency of the partnering loudspeakers
will affect the V 80 SE's sound.
The enhanced display functions of the bias measurement facilit
y
enable the owner to correctly set the bias current for the wide range o
f
output tubes that are compatible with the V 80 SE. Bias adjustment is
carried out using 3-turn precision regulators in conjunction with LEDs fo
r
each of the four output tubes.
POWER MANAGEMENT
The high voltage systems and the heaters for the power and preamp
tubes form part of a logic-control chain. The power management system
also controls the electronic protection and power saving functionalit
y
(Ecomode). The electronic protection continuousl
y
monitors th
e
current throu
g
h the power tubes and the operatin
g
volta
g
e of th
e
driver stage. This protects the unit from any overload situation including
power line surges (for example: speaker short circuit, faulty power tube,
lightning strike on the power line). The main purpose of the protection
system is to prevent damage to the amplifier; its secondary purpose it to
protect the power tubes from the harmful long-term effects of overload. At
the same time, it enhances user safety by preventing the occurrence o
f
critical conditions that could be harmful to the user.
DOUBLE SAFETY +
LONG SERVICE LIFE
Like other OCTAVE products, this amplifier is equipped with a double
safety system. This means that, if a component should fail and trigger the
electronic protection, a second, higher-level safety feature will always be
present. This technology has proven invaluable in recent years. It ha
s
enabled us to reduce our overall failure rate
(
exceptin
g
outpu
t
tubes, which we are unable to control 100 percent
)
to virtuall
y
zero.
OCTAVE equipment is desi
g
ned for achieve a service life of 10 to 1
5
years without needing to be serviced. This is particularly importan
t
feature for a tube-based amplifier, as many preconceptions still exist with
regard to the technology's durability and long-term stability.
