Audio Note R-Zero - Manual

- - 1
Congratulations on your purchase of the Audio Note™ RIAA-ZERO PHONO stage.
The RIAA-ZERO provides outstanding performance as an additional unit for line level
playback systems, is of a compact size and represents excellent value.
Please read over this manual carefully in order to obtain the best possible performance
and longevity from the RIAA-ZERO.
UNPACKING & INSTALLATION
We recommend that you store the packaging materials in case the unit requires shipping
at a later date. Also, check that no transit damage has occurred before installing the pre
amplifier.
Next, select a suitable location for the unit, not next to any large mains unit or damp
areas.
Worthwhile improvements may be obtained by locating the pre amplifier on a support
system specifically designed to reduce and absorb any vibrations.
AFTER CARE
Cleaning: No special maintenance is required for the RIAA-ZERO. A soft cloth or
brush similar to those sold by photographic stores for lens cleaning applications is best
used for cleaning.
Use a cloth lighty dampened with a mildly warm, weak soap solution to clean off grease
or oily substances. Strong or alcohol based solvents may damage the finish of this
amplifier.
Tube replacement: The vacuum tube used in the RIAA-ZERO should provide about
two years of continuous operation. With three hours of use per day, they should
provide a 10,000 hour life span.
Audio Note has taken considerable care in selecting and matching vacuum tubes
specially for the RIAA-ZERO, and so we recommend that you contact your Audio Note
dealer, who will be able to provide the correct tube should replacement be required.
