Unpacking the amplifier:
Immediately upon receipt of the amplifier, inspect the carton for possible damage
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 content of the carton is as follows:
1 pcs Electrocompaniet Ampliwire x1 0
1 pcs AC power cord
1 pcs Owners Manual
1 pcs Inspection Card
pcs ECP5XLR
1 pcs Spare fuse, 5.0 AT slow-blow 5x 0mm (1 0V AC)
1 pcs EC 4.9 – AW 1 0 Communication cable
.5 AT slow-blow 5x 0mm ( 0V AC)
The actual spare fuse is located inside the AC 3 pin receptacle.
Connecting the AW 2x120
Connecting to mains
Check that the mains voltage printed on the rear panel of the amplifier corresponds
with the line voltage in the territory were you intend to use your amplifier.
How to avoid damages
A good operating practice is to turn off all equipment before any connections or
disconnection’s are made. Do not under any circumstances connect or disconnect
equipment when power is turned on. If you insist on connecting or disconnecting
while power is turned on, you should be aware that the design of the RCA plug
generates a large transient when inserting the plug. This could damage both the
speakers and the amplifier.
WARNING: To reduce risk of fire or electric shock, do not expose this appliance to rain
or moisture. Verify line voltage before use.
Do not remove cover. No user serviceable parts inside. Refer servicing to qualified
service personnel. The warranty in void if the product is tampered with by non
authorised personnel. Use only authorised Electrocompaniet service station.
The rear panel
The rear panel of the Ampliwire AW x1 0 is equipped with XLR inputs.
alanced XLR operation
Use an interconnect with ground on pin 1, + on pin and – on pin 3
Single ended operation
Use an RCA to XLR adapter (ECP5XLR).
Connect ECP5XLR to the XLR input.
Connect the RCA interconnect to the input on the ECP5XLR
Speakers
Connect the speakers to the + and - output terminals
Spac
Connect the EC 4.9 – AW 1 0 Communication cable from the Spac port to EC 4.8
or EC 4.9 preamplifier to enable automatically bridging.
ridge (mono) mode
When the amplifier is used in mono mode the XLR input 1 and Speaker output 1 is
used. If you use EC 4.9 – AW 1 0 communication cable and connect this from Spac
output to EC 4.9 or EC 4.8, the AW x1 0 will switch into mono mode
automatically.
To manually switch the AW x1 0 into mono mode push the bridge button. Note
that when an EC 4.9 – AW 1 0 communication cable is connected to the AW
x1 0, this button is not used.
Upgrade
The AW x1 0 is prepared to be upgraded to 3x1 0. The input 3 is reserved for this
upgrade. Contact Electrocompaniet or your dealer for more information about this
upgrade.

Important Notice
For optimal sonic performance, the AW x1 0 should be burned in for a minimum
time of 7 hours.
If the AW x1 0 has been switched off, allow two hours of warm-up for optimal
sonic performance.
Due to high class A operation in all Electrocompaniet designs, it is normal for the
AW x1 0 to feel warm. Proper ventilation is important.Never cover the ventilation
area. A good rule of thumb is to allow at least 3 - 5 cm (1 - inches) of air sidewise,
and 5 – 8 cm ( - 3 inches) above the EC 4.9.
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:
ELECTROCOMPANIET AS,
REIVIKVEIEN 7,
4120 TAU,
NORWAY

The end-user is responsible for all shipping charges, insurance, and re-importation
and duty charges.
When shipping a product to the factory for service, always include the following:
1.A sales slip or other proof of purchase if repair is claimed under warranty.
.A proforma invoice with value of goods, stating that the amplifier is being
returned to Norway for repair.
3.An accompanying letter describing faults, symptoms, or problems with the
unit.
4.Always ship the unit in its original carton and packaging material to prevent
damage in transit. Electrocompaniet will not cover damages incurred in transit.
If you require further information concerning the operation of the unit or if you have
any questions related to service, please do not hesitate to contact your dealer or
national distributor.
