ELECTROCOMPANIET PI-1 User manual

PI-1

Unpacking the PI-1
Immediately upon receipt of the PI-1, inspect the carton for possible damage during shipment.
The carton and packaging have been designed to provide the safest possible protection for transport
of your integrated amplifier.
Unpack the unit carefully. Save all packaging materials for future shipment.
The contents of the carton
1 pcs Electrocompaniet PI-1
1 pcs AC mains cord.
1 pcs inspection card.
Set up procedure
Before connecting the PI-1 to the mains, check that the main voltage indicated on the rear panel
corresponds to the line voltage in the territory where you intend to use the unit.
How to avoid damages
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-1 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 set-ups 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 1.
Inputs
Single- ended operation:
There are two sets of single ended inputs labelled Tuner and HT/TV.
All inputs are similar regarding sonic performance.
Balanced operation:
There are two sets of balanced inputs labelled AUX and CD.
The balanced mode can only be used if the signal source has a balanced output. Use an XLR
interconnect with GND on pin 1, + on pin 2 and – on pin 3.
Speaker Outputs
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-1 off when you connect the speakers.
Front panel
See illustration 2.
The main switch 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 goes from 0 to 127.
The available input sources are:
CD : Balanced operation on source connected to CD input.
TUN : Single ended operation on source connected to Tuner input.
HTV : Single ended operation on source connected to HT/TV input.
AUX : Balanced operation on source connected to AUX input.
Navigator window
This window in the middle of the front panel shows what source that is currently active and the
current listening volume.

How to power up your system
You should always power up your system in the following way:
Signal sources (CD player, tuner, etc.) first, then the PI-1.
When switching off your system
First turn of the PI-1, then the signal sources.
Error codes
If the PI-1 is not working properly, the display will show an error code.
These error codes are:
Error code Description
ERR SC Short circuit on the loudspeaker terminals. Make sure that the + and – parts of the
loudspeaker cables are not in contact and that the speaker cables are not in connect
with the PI-1.
ERR DC Internal fault. Please contact service.
ERR TMP The PI-1 has 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-1.
Turn down the volume and make sure there is enough free space around the PI-1.

Input configurations
XLR input: 1 = ground 2 = positive 3 = negative
RCA: Circle = ground Centre = positive

Important Notice
For optimal sonic performance, the PI-1 should be burned in for a minimum time of 72 hours.
If the PI-1 has been switched off, allow two hours of warm-up for optimal sonic performance.
Proper ventilation is important.
Never cover the ventilation area.
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-1.
If service is needed
Your dealer will have all relevant information regarding the service centre in your area and will
ensure that your unit is serviced with minimum delay.
It is our general policy to have your unit returned to you within five working days.
This is an average time and can vary locally, depending on the workload at that particular service
centre.
If, for some reason, there are no service facilities available in your country, please ship the unit to
the following address:
