GETTING STARTED

INTRODUCTION

Congratulations on your selection of the Boulder 2010 Preamplifier. 

We at Boulder Amplifiers are certain it will provide years of listening 

pleasure.

BEFORE YOU START

To get started listening, you only need to connect the 2010 as you 

would any other preamplifier and the power supply as on page 1-3, but 

you should take note of the following.

WARNING: The polished volume control is attractive and because it 

is optical and has no stops, it is really tempting to just spin it around. DO 

THIS ONLY WITH THE POWER OFF! It must be given the respect you 

would any other volume control with its 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 the problem. See troubleshooting section.

For the 2010 to work properly, the Boulderlink’s MASTER/SLAVE 

switch should be set to MASTER.

A  thorough  reading  of  this  manual  will  definitely  enhance  your 

enjoyment of your 2010 Preamplifier.
