PEAKER CONNECTIONS
Speaker connections are made using the supplied 4-way wiring harness. Connect the bare wire ends to the
speaker driver or drivers (using crimp terminals if suitable), then plug the 4-way socket onto the 4-way 3.96 mm
pitch header. The two connection options are shown in the diagram below.
2-ch mode
In 2-ch mode (also called SE or single-ended mode), the amplifier is connected to two speaker
drivers. The plugin must be configured in 2-ch mode (see page 28), and the wiring connected to
the two drivers with channel and polarity as shown on the left of the diagram below.
BTL mode
In BTL (bridge-tied load) mode, the amplifier is connected to a single speaker driver. BTL mode
uses both “hot” wires as shown in the diagram below, and the “cold” wires are not used. The
unused wires must be cut short or insulated to ensure that they do not contact anything. The
plugin must be configured in BTL mode (see page 28).
3.7.1
Output level jumper
Either channel can have the analog output signal reduced by 16 dB by opening a jumper on the rear of the DSP
board. This is used in situations such as a two-way loudspeaker with a sensitive tweeter.
