than expected the AUDIOVALVE
Team is happy and proud to annouce the new headphone amp RKV
Based on the legendery RKV
MARK II (
since 1982 ) Mr. Becker - the designer - has developed this new
headphoneamp with unique new and interesting features. It will
be launched by beginning of November.
pictures are shown our also new ivory edition for all models,
which are coming with a special high quality ivory colour
chassis, special cables and some extra components.
Audio enthusiasts who listen to their music via headphones usually have more than one pair of headphones for their enjoyment. To take this into account, we have developed the new RKV Mark 3 headphone amplifier. This amplifier is designed to offer optimum performance for a variety of low to high impedance headphones.
This amplifier will give hours of immersive fatigue free listening and works flawlessly over the entire frequency range. This amplifier is a must have for anyone searching to discover new depths in music and sounds via headphones.
The new RKV MARK 3 headphone
tube amplifier is a beauty. It's ability to render fully
believable, 3D images, replete with harmonic richness is
unparalleled. That's what it comes back to, again - music. Amid
all the subjective observations and objective measurements that
one can muster, the ineffable, emotional feel of the music is
what many of us are seeking. And it will be so easy you'll wonder
how you ever survived without it. The RKV MARk 3 is simply such a
stellar performer it doesn't leave much left to be desired.
puts most of our budget towards the sound quality of our design
and components rather than all of the audio jewelry and
marketable designs featured by some of the comparable sounding
amplifiers on the market. We would say on sound alone it
outclasses its price point, for design and fit and finish it
fulfills our expectations of an established company in this price
range. Sound wise this amplifier ticks all the boxes, great
tonality, world class 3D sound stage, a noise floor on par with
all but the very best valve based amplifiers, and macro and micro
dynamics in spades. The sound quality of the RKV MARK 3 is of
absolute top reference level for an OTL based headphone tube
amplifier. The pros to this are rock very low noise floor, low
distortions, high frequence range, high damping, very natural and
musical tonality, wide impedance matching, perfect open
soundstage and so on. This amp isn't for the weak of heart - this
is an audioholic's . Highly recommended is an understatement, we
can't tell you how impressed we have been with the development of
this headphone tube amplifer.
On the left
side of the front aperture , the two jacks for headphones and
three rotary switches. The headphone jacks are connected in
parallel when using the 6.3 mm connectors. For the use of XLR
connectors , take the lower bushing for the right ear and the top
of the left ear . Below the two headphone jacks is the Mode
switch. Use it to select the mode with which you want to hear.
Use the OTL mode if you have a high-impedance headphones (>
100 Ohms) , or benefit you if your headset has the IMP mode less
than 100 ohms impedance , or if you intend to use speakers. Which
musical impedance best suit with your headphones , you have to
find out for yourself. Just turn on the IMPEDANCE switch. With
the last of the three rotary switches on the left, select the
source you want to listen to. Then a total of 45 ( 4 +1) RCA
inputs for disposal . Input 1 + 2 are also equipped with XLR
inputs. Input 5 is occupied by the built-in phono module. Of
these RCA phono jacks ( 5 ) you can pass the phono signal to
other devices .
In the middle of
the front panel you find the alps volume pot, right the balance
control and left the power switch. When the unit is in operation,
a green LED lights in the switch.
The excellent results
the headphone amplifier RKV MARK 3 provides, aren´t only based
on the sophisticated design of the circuit board. A perfect
developed circuit design is only perfect when it is implemented in
accordance with the practice. For all these products AudioValve
theoretical and practical symboise is harmonious and coherent. This
leads to a matchless musical reproduction of all sound sources. Also
in RKV Mark 3 is a fully automatic biasing servo controller to use.
In our new approach we have chosen a OPA134.
In this picture
you can see the left section of
the board, the phono section and the right headphone protector.
The phono module is classic old school style and built with hand
selected components, and fantastic musically.
headphone protector reliably protects the headphones from pulses
that can occur when switching ON or switching OFF
the amplifier. The outputs of the amplifier are shorted for
this time both on power as in both cases.
Months in ongoing testing of the
Mark 3 was developed to perfection. In many updates over and over
again the case, the circuit and PCB layout has been optimized. At
the end of this long period, we got the perfect product in front of
and the 10 kHz squarewave is absolutely fast ( OTL - mode )
- CLIPPING / OVERLOAD circuit -
When the red sine wave at the
output of the OPA reaches the upper or lower limit of supply
voltage (out of range), one of the two red LED ( green / blue
wave ) lights as an indication of an overload of the amplifier.
Then either the volume is too high, impedance is mismatched, or a
tube of this channel is faulty.
