10.3.5.2 Loudspeaker lines

Between the Lsp Out+ and Lsp Out- connections, the loudspeakers must be connected. The voltage between these connections (100 V, 70 V) depends on the position of the jumper on the output board (see figure 10.7).

It is possible to use the different voltages to reduce the volume of the loudspeaker line. For example, if all loudspeakers are suitable for 100 V, the maximum output level is 40 dBV. If the loudspeaker line voltage is set to 70 V, the maximum output level is reduced to 37 dBV (difference: -3 dB).

Caution

Check the specifications of the loudspeakers to find out which maximum voltage can be provided on the loudspeakers outputs of the power amplifiers.

To reduce the risk of electric shock do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so. See section 1.2 Intended audience.
