AW 120 Owner’s Manual 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. 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 120 DMB 1 pcs AC power cord 1 Owner's Manual 2 pcs adapter, ECP5XLR 1 pcs Spare fuse, 5.0 AT slow-blow 5x20mm (120V AC) 2.5 AT slow-blow 5x20mm (220V AC) The actual spare fuse is located inside the AC 3 pin receptacle. Connecting the AW 120 DMB 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. The rear panel The rear panel of the Ampliwire AW 120 DMB is equipped with both and XLR input (female) and output(male), for link options. (Biamping, multiroom etc.) AW 120 also features speakon connectors in addition to ordinary speaker terminals. Balanced XLR operation Use an interconnect with gnd on pin 1, + on pin 2 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 Balanced bridged mode (Mono) Use an XLR interconnect from the preamplifiers balanced output left or right to the power amplifiers right input. Link from the power amplifiers right XLR output to the power amplifiers left XLR input. This link must turn the phase of + and -. Connect the speakers + to the amplifiers right out +. Connect the speakers – to the amplifiers left out +. Balanced bridged mode (Mono) Use the interconnect EC-K5-SPLITT. Connect the end marked red to the left input on the amplifier. Connect the speakers + to the amplifiers right out +. Connect the speakers – to the amplifiers left out +.
