Unpacking the PI 2D
Immediately upon receipt of the amplifier, inspect the carton for possible dam-
age during shipment. If the carton is visibly damaged, a claim must be filed
with the carrier as soon as possible.
Unpack the unit carefully, and please do remember to save all packaging
materials for future shipment. The carton and packaging have been designed to
offer the safest possible protection when transporting your amplifier.
The contents of the carton
•1 pc. Electrocompaniet PI 2D Integrated Amplifier
• 1 pc. AC power cord
• 1 pc. Owner's Manual
• 1 pc. Inspection Card
• 1 pc. Remote control
• 2 pcs. batteries.
Set up procedure
Before connecting the PI 2D to the mains, check that the main voltage
indicated on the rear panel corresponds to the line voltage in the terri-
tory where you intend to use the unit.
How to avoid damages
A good operating practice is to turn off all equipment before any con-
nections or disconnection’s are made. Do not under any circumstances
connect or disconnect equipment when power is turned on. The design
of the RCA plug generates a huge transient when inserted. Connecting
or disconnecting equipment with the power on can result in severe
damage to both speakers and amplifier.
How to avoid noise problems
The PI 2D contains delicate circuits that are sensitive to magnetic stray
fields. The unit should not be placed near main transformers, TV sets,
etc. Care should also be taken regarding placement of the interconnect
cables. Do not run interconnect cables in parallel with main cords or
speaker cables. Keep interconnect cables as short as possible.
How to avoid possible antenna problems
In some setups hum may occur when you connect the radio, VCR or TV
to your system. The problem is caused by DC voltage coming from your
antenna. Please contact your cable network operator.

How to connect your system ( See illustration, page 10.)
Single - ended operation: ( See illustration "back panel", page 9.)
There are 4 sets of single ended inputs labelled: DVD, Tuner, AUX, HT.
All inputs are similar regarding sonic performance.
Balanced operation: ( See illustration "back panel", page 9.)
There are one set of balanced inputs labeled CD. The balanced mode can
only be used if the signal source has a balanced output. Use an XLR inter-
connect with GND on pin 1, + on pin 2 and – on pin 3.
Speaker outputs ( See illustration "back panel", page 9.)
Connect the red connector to the plus side on the speakers and the white
connector to the minus side on the speakers. Never short the positive output to
ground or chassis. Always switch the PI 2D off when you connect the speakers.
Front panel ( See illustration "front panel", page 8.)
The standby button is located on the left side of the front panel.
The four buttons on the right-hand side of the front panel is used to adjust
the volume and select the input source. Use the up and down buttons to
adjust the volume, and the left and right buttons to select input source. The
volume range is 0 to 100.
HT (Home Theatre)
HT is a direct input where the volume control is bypassed. PI 2D will
work like a power amplifier with fixed gain. When selected the output
will be muted for a few seconds as a safety against accidental overload.
SPDIF inputs
PI 2D will accept optical SPDIF sources up to 96 kHz/24bit on inputs
TOSLink1 and TOSLink2. Please use a optical TOSLink cable for this con-
nection. Connect coaxial sources up to 192kHz/24bit to inputs COAX1
and COAX2. Please use a coaxial SPDIF cable for this connection.
USB input ( See illustration "back panel", page 9.)
The USB input accept sources up to 24bit/192kHz. Connect a PC/Mac/
Linux computer using a standard type A-B USB cable. PI 2D will show up
as a sound device on your computer. Please select PI 2D as the active
device to enable playback through PI 2D. On Windows drivers are
needed. Please install the drivers before connecting the USB cable and
follow the instructions. During installation you will be asked to connect
the USB cable. The latest drivers can be downloaded from: www.electro-
companiet.no/downloads.
How to power up your system
You should always power up your system the following way:
Signal sources (CD player, tuner etc.) first. Allow a 30 seconds warm-up
before you turn on the PI 2D.

ENG
This window in the middle of the front panel shows which source is currently
active. The listening volume will be displayed when the volume is adjusted
using the remote control or the navigator up/down buttons. The display may
be turned off using the DIM AMP button on the remote. If turned off, the dis-
play will come back on for 5 seconds if any button is pressed on the remote
or the navigator.

Error codes
If the PI 2D is not working properly, the display will show an error code.
For other troubleshooting please contact your local dealer or our support
department. All contact information you will find at www.electrocompaniet.no
Error text Description What to do
DC L DC voltage left channel Please contact service center.
DC R DC voltage right
channel
DC DC left + right channels
OVRLD L Overload left channel
Make sure that the + and – leads
of the loudspeaker cables are
not shorted, and that the speaker
cables are not in contact with the
chassis of PI 2D.
OVRLD R Overload right channel
OVRLOAD Overload left+right chan-
nels
TEMP L Left channel overheated The amplifier is overheated. This
is caused by either playing to
loud for a long period of time,
or not enough free space on the
sides or above the PI 2D.
Turn down the volume and make
sure there is enough free space
around the amplifier.

Important Notice
For optimal sonic performance, the PI 2D should be burned in for a
minimum time of 72 hours. If the PI 2D has been switched off, allow two
hours of warm-up for optimal sonic performance. It is normal for the
PI 2D to feel warm. A good rule of thumb is to allow at least 3 - 5 cm
(1 - 2 inches) of air sidewise, and 5 - 8 cm(2 - 3 inches) above the PI 2D
