D-Series Dual Channel Power Amplifiers are developed as an easy to use, flexible flexible solution for multifunctional use. During the development of the D2 – D3 – D4 – D5 power amplifier, the AUDAC-engineers wanted to achieve three goals:...
Chapter Environment Do not place this unit in an enclosed environment such as a bookshelf or closet. Ensure there is adequate ventilation to cool the unit. Do not block the ventilation openings. Do not place the unit in environments which contain high levels of dust, heat, moisture or vibration.
Only use a grounded socket outlet and a power cord with grounding plug. This unit is not a toy. It should not be operated by children. Do not stick objects through the openings of the D2 – D3 – D4 – D5. Do not open the unit (risk for electrical shock).

7. Operation mode switch: By means of this switch, the operation mode of the amplifier can be selected between stereo mode or bridge mode. For most standard applications the amplifier will be used in stereo mode whereby this switch should be turned to the left position. When using in bridged mode, the power of both channels will be merged with each other and this switch should be turned to the right position.
Chapter Connecting the Amplifier Input connections The input connections of the amplifier are performed using balanced XLR connectors. Every channel has an XLR input connector. The input signal from the signal source, pre-amplifier or mixer should be connected to the XLR input connections. By means of the operation mode switch, the operational mode for the amplifier can be selected between Stereo mode and Bridge mode.

2) Bridge mono Mode: In bridged mono mode, the power of both output channels is merged to deliver double the power to one single load. The operation mode switch should be positioned in the Bridge position (Right position of the switch). The output of the signal source should only be connected with the Channel 1 XLR input connector of the amplifier.
Output connections The loudspeaker connections are performed by using Speakon connectors. The loudspeakers should be connected to the corresponding Speakon connector. The used Speakon connectors are 4-pole versions. At the contacts of Speakon 1 (Channel 1), are the output signals available for both output channels. Contacts +1 and -1 contain the signal for output Channel 1, while contacts +2 and -2 contain the signal for output Channel 2.
+1 and +2 terminals of Speakon connector one. Connection standards The in- and output connections of AUDAC audio equipment are performed corresponding to international wiring standards for professional audio equipment. XLR: 1 = ground / shield...
