The table shows the input current taken by the various loudspeakers.
Nominal current at nominal voltage.
Table 1: Electrical Ratings.
It is important that the loudspeakers are connected to power amplifiers that have outputs that are compatible to the type of loudspeaker
being used. Loudspeakers with a 70V or 100V line matching transformer fitted must be connected to a power amplifier with a 70V or
100V line output. Low impedance 8 ohm or 16 ohm loudspeakers must be connected to amplifiers with a suitable low impedance
output.
The above table shows the maximum AC signal voltages at which the loudspeakers can be operated
The input current will vary according to the voltage input level and the frequency of the tone selected.
The current levels taken by the each loudspeaker will depend on which output tapping has been selected (see section 12 & 13 of this
instruction manual). BExL25D 70V and 100V Line units have output levels of 25W, 12.5W, 6W and 2W; BExL15D 70V and 100V Line
units have output levels of 15W, 7.5W, 3W and 1W.
