Introduction

Congratulations on your selection of the Boulder 2110 Preamplier. Please

be sure to read this manual before attempting to connect or use the 2110.

Before You Start

To get started listening, you only need to connect the 2110 as you would

any other preamplier and the power supply as on page 1-3, but you should

take note of the following.

WARNING: The polished volume control is attractive. Because it is optically

controlled and has no stops, it is very tempting to spin it. ONLY DO

THIS WITH THE POWER OFF! It must be given respect as it can rotate

incredibly quickly and has ability to get loud very fast. By the time you have

turned it up to -40.0 dB with a source connected and turned on, you should

hear music. If not, do not continue to raise the volume until the problem is

solved. Please see the troubleshooting section.

If your 2110 is connected to other Boulder components through Boulder

Link, The rear panel MASTER/SLAVE switch should be set to MASTER.

Placement of the 2110 Preamplier

Your Boulder 2110 Preamplier is designed to reduce the effects that

external magnetic elds and radio frequencies (RF) have on its circuitry.

While placement is not critical, known magnetic elds should be avoided

whenever possible. Also, the preamplier should be placed in line of sight

from the intended listening position. This is necessary for the remote control

to function properly.

Because the preamplier and its power supply are heavy, a solid, stable

surface should be used. Both chassis will generate some heat, so they

should be placed with plenty of good air circulation around them. In

particular, make sure that the slots on the rear of the power supply are not

blocked. You may also want to have some access to the rear panels for

cable changes.

Connecting the 2100 Power Supply to the 2110 Chassis (part 1)

Your Boulder 2110 Preamplier is supplied with a Boulder 2100 Power

Supply. Each of the four internal supplies is independent of the others

except for the front panel LED, which conrms the correct operation of all

four internal power supplies.

Three cables are provided for connecting the power supply to its matched

preamplier chassis. Two of these cables have 5 pin connectors and are

used for connecting the left and right audio supplies (±27V). The third one

has 7 pin connectors and is used for the digital supply (+5V). Care must be

taken not to confuse these as any attempt to insert the wrong connector will

result in damage.

CAUTION: Connect and disconnect these cables ONLY after the power

supply has been turned off for at least one minute.
