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.

1-1
PLACEMENT OF THE 810 PREAMPLIFIER
Your Boulder 810 Preamplifier is designed to reduce the effects that
external magnetic and radio fields (RF) have on its internal circuitry.
While placement is not critical, known magnetic fields should be
avoided. Line of sight from the listening position is necessary for the
remote control to function properly.
Because the preamplifier is heavy, a solid, stable surface should be
used. As it will generate some heat, there should be good air circulation
around it.
You may want to have some access to the rear panels for cable
changes.

CONNECTING TO THE MAINS OUTLET
Your 810 Preamplifier is supplied with a mains cord suitable to the
location where it was purchased.
The exact voltage and frequency range is indicated on the rear panel.
Make certain that the mains voltage used is within the specifications
shown. Also listed are the fuse ratings. There are two fuse holders
on the rear of the 810, one for each of the digital and analog power
transformers.
Use only specified fuses. Check with a qualified service person
first.

POLARITY
Please note that the 810 Preamplifier conforms to the standard of pin
2 as the positive or hot pin for all analog balanced inputs and outputs.
Because input and output polarities are handled through programming
setups and the remote control, no concern for polarity is needed while
connecting sources.
CONNECTING A BALANCED ANALOG SOURCE
To fully realize the sonic potential of your 810 Preamplifier, use
balanced connections whenever possible. Balanced cables reduce
interference from magnetic and RF sources to an absolute minimum.
Connect each line source to one of the four inputs provided. Later,
you will be able to name each input with the source’s name, so you
might want to make a list as you connect them.
