Dear AudioValve fan,
we are delighted that you have for your audio - have bought a device from AudioValve hobby. We know
this much appreciated and will always strive to meet your expectations.
The RKV MARK 3 is a logical development of our highly successful predecessor models RKV. This
amplifier is designed for playing music through headphones in the first place, and can act in different
impedances. You can also use the amplifier but also for playing background music about speakers.
Playing music through speakers has minor importance because the power of the amplifier is rated for
headphones.
The AudioValve - RKV MARK 3 is a small-power amplifier, specially designed to drive headphones. It
offers a sound quality and driving capabilities far beyond that of an ordinary headphone socket found on
a CD-player or amplifier and thus allows you to exploit the full sonic potential of your headphones.
Due to the close contact to your ears, headphones provide an extreme channel separation whilst
listening to stereo recordings. Unlike loudspeakers, none of the sonic information in the left channel is
acoustically transferred to the right ear and vice versa. Although this adds to the extreme high level of
detail that can be achieved with headphones, it subconsciously also introduces mental stress. The
natural correlation of stereo sound interpreted by the brain is lost.
The AudioValve - RKV MARK 3 not only offers normal stereo reproduction of your music, but it also has
a facility to add some of the left channel information to that of the right channel and vice versa. Thus
mental stress is reduced and music can be enjoyed with more ease.
For safety and in order to obtain the best possible results with your new headphone preamplifier, we
ask you to read these instructions carefully. The RKV MARK 3 was developed by music-lovers for
music-lovers and we hope that it will serve you well for a long time.
Connections
At the rear side of the AudioValve - RKV MARK 3 more pairs of inputs allow you to connect different
audio sources that have typical output voltages (CD- player, cassette-player, tuner, mini disc-player, ...).
The source you want to listen to can be selected by the rotary switch at the left front side of the amp.
The RKV MARK 3 can also be used as a preamp. He has two gold-plated XLR female connectors for
even the back wall, which also vary in level with the volume control. Its signal come from the OTL
stages divided signal level by 10. With two sockets, for the left and right channel, only the pin 2 is
occupied hot plus phase.
Your headphone should be connected to one of the headphone - sockets on the front side of the RKV
MARK 3. You can also use the sockets to connect two headphones simultaneously.
The sockets are intended for 6.35 mm stereo jacks and for XLR jackets too. The top jacket support the
left channel ( XLR pin 2 ) and the bottom jacket support the right channel ( XLR pin 2 ). If your
headphone only has a 3.5 mm jack, then use an adapter that can be obtained in most electronics or
audio shops.
