- Page 3 The design features of Ampliwire 250 DMB After the Electrocompaniet 25 watt amplifier had established a new standard for transistor amplifiers, research was undertaken to find ways to make the amplifier even better, and to extend its highly musical sound quality to more powerful amplifier designs. The engineers at Electrocompaniet were not satisfied by only reducing the commonly recognised types of distortion to low levels.
- Page 4 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.
- Page 5 Balanced XLR input and operation The balanced mode can only be used if the preamplifier has a balanced output. In order to use the balanced XLR- input, turn off the amplifier, and remove the shorting plugs from the negative (-) RCA inputs.Use an XLR interconnect with GND on pin 1, + on pin 2 and - on pin 3.
- Page 6 Warning: The amplifier will be warm. Due to the high class A operating point used in the Electrocompaniet design, it is normal that the amplifier feels warm. Proper ventilation will be needed, and the amplifier should not be covered in. A good rule is to allow 1 - 2 inches of air sidewise, and 2 - 3 inches above the amplifier.
