Connection - Turntable
One set of RCA output connectors are provided marked `INPUT`. The connectors are
colour coded with red and white bands for quick channel identification with red being the right
channel and white being the left channel. Connect the turntable lead to these sockets. If you
have an earth lead connect it to the screw earth terminal.
Connection to Pre-amp or Integrated Amplifier
One set of RCA output connectors are provided marked `OUTPUT`. The connectors are
colour coded with red and white bands for quick channel identification with red being the right
channel and white being the left channel. Connect the R Zero/II to any line input on your pre-amp
or integrated amplifier (eg: aux, av, etc).
Special Note: make sure that all connections are tight and clean. For best performance,
use good quality audio interconnect. Although several companies manufacture good quality
interconnects, those manufactured by
A udio Note are excellent!
USING THE R Zero/II
Once all connections are completed and checked, flip the main on/off switch located next
to the mains input socket to the “on” position. The red indicator on the front panel should
now be glowing. Being vacuum tube, the pre amplifier will take about 45 seconds before it is
ready for operation. The power amplifier may now be turned on.
Bedding in time: The new pre amplifier requires about 200 hours of initial use (called “bedding in
time”) before the circuitry becomes stable and optimum performance is realised. As the amplifier
“beds in”, the sound will become more lucid, detailed and expansive.
Once the R Zero/II is “bedded in”, a warm-up time of approximately 30 to 45 minutes is
required each time the unit is turned on before optimum sonic performance is reached.
The R Zero/II is designed for continuous operation and may remain switched on, even
when not in use. The power consumption is minimal. You may, however, prefer to turn the unit
off when not in use by using the “ON/OFF” switch located on the rear panel, next to the mains
inlet socket.
TECHNICAL OVERVIEW
The R Zero/II meets the requirements of Level Zero and the basic technological
requirements of all Audio Note™ products. Audio Note™ use a technique called “Comparison by
Contrast” * during the development of our products. This method of aural evaluation is a system
currently unique to Audio Note. High quality parts are used throughout the phono stage. The
circuitry is simple and incredibly effective, yielding a high level of sonic performance.
* An essay titled ‘Audio Hell’ that describes the Comparison by Contrast technique is available on Audio Note web
site under link http://www.audionote.co.uk/articles/art_audio_hell.shtml.
