CONNECTION OF 25 V INPUTS TO AN AMPLIFIER
HAVING LOW IMPEDANCE OUTPUTS
25 V inputs can be used to connect one or more loudspeakers in parallel to
an amplifier (for instance, professional or Hi-Fi type) having low impedance
outputs (usually 4 – 8 Ω).
The total impedance of the loudspeaker line shall not be lower than the
amplifier output impedance. The total impedance of the loudspeaker line can
be calculated by dividing the single value 63 Ω (when selecting the 10 W
power) for the number of DU 100X loudspeakers linked in parallel.
