PLACEMENT OF YOUR 2020 D/A CONVERTER
Your Boulder 2020 is designed to reduce interference from external mag-
netic and radio fields (RF). 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 converter and its power supply are heavy, a solid, stable sur-
face should be used. As both will generate some heat, they should be allowed
to have good air circulation around them. In particular, make certain that the
fins on the rear of the supply are not blocked.
You may want to have some access to the rear panels for cable changes.
1-1 GETTING
STARTED

CONNECTING THE POWER
SUPPLY TO THE MAIN CHASSIS
Your Boulder 2020 Converter is sup-
plied with a Boulder 2000 Triple Power
Supply. Each of the three supplies is
independent of the others except for the
front panel LED which confirms correct
power supply operation of all three sup-
plies.
Three cables are provided for con-
necting the power supply to the main
chassis. Two of these cables have 4 pin
connectors and are used for connecting
the left and right audio supplies (±27V).
The third one has 5 pin connectors and
is used for the digital supplies (+5V).
Care must be taken not to confuse
these as any attempt to insert the wrong connector will result in a damaged
connector.
CAUTION: Connect and disconnect these cables only with the power sup-
ply turned off.
1-2 GETTING
STARTED

CONNECTING TO THE MAINS OUTLET
Your 2000 Power Supply is supplied with a mains cord suitable to the loca-
tion where it was purchased.
One of the features of the 2000 is its universal automatic voltage-selecting
power supply. Simply plug it into any standard outlet. (Exact voltage and fre-
quency compatibility is stated in the specifications section.)
1-3 GETTING
STARTED

CONNECTING AHARDWIRE
DIGITALAUDIO SOURCE
Four balanced AES/EBU digital
audio inputs are provided on the rear
panel of the main chassis. Each input
may be converted to unbalanced 75Ω
coax by the use of a Boulder
Digital Input Adapter. This adapter has
a special internal network to properly
terminate the cable, and must not be
confused with one made for analog
audio.
Connect each 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.

CONNECTING AN OPTICAL DIGITAL AUDIO SOURCE
Two optical inputs are also provided on the main chassis– a glass fiber con-
nection known as “ST Glass” and a plastic fiber known as “Toslink.” Remove
the protective caps before trying to insert the connector. (Store the caps in a
safe place.)
The “ST Glass” input will be selected as input 5, and the “Toslink” input
will be selected as input 6. Again, keep track of what sources you connect
because you will be able to name them later.
1-5 GETTING
STARTED

CONNECTING TO ABALANCED
INPUT PREAMPLIFIER
Because your 2020 Converter’s bal-
anced output has a very low output
impedance, any practical distance
between converter and preamplifier will
not be a problem.
The Boulder series Balanced Cables
will give the best possible sonic
connection.
Connect each of the 2020’s outputs
marked “MAIN OUTPUT” on the chan-
nel audio assemblies to the inputs on
your preamplifier.
POLARITY
Please note that your Boulder 2020 Converter conforms to the new stan-
dard of pin 2 as the high or hot pin for all balanced outputs.
