GETTING STARTED
INTRODUCTION
Congratulations on your selection of the Boulder 810 Preamplifier.
We at Boulder Amplifiers are certain it will provide years of listening
pleasure.
QUICK START
To get started listening, you only need to connect the 810 as you would
any other preamplifier, but you should take note of the following.
WARNING: The volume control is attractive and because it is optical
and has no stops, it is tempting to just spin it. DO THIS ONLY WITH
THE POWER OFF! It must be given the respect you would any other
volume control with the ability to get loud very quickly. By the time
you have turned it up to -40.0 dB with a source turned on, you should
be hearing some music. If not, don’t proceed any louder until you have
solved this problem. See trouble shooting section.
For the 810 to work properly, the Boulderlink’s MASTER/SLAVE
switch should be set to MASTER in most instances.
A thorough reading of this manual will definitely enhance your
enjoyment of your 810 Preamplifier.
