The EX26 Control Panel
The EX26 features an easy to use control panel
featuring AC power in, audio input and through
output, level control, LED status light
and a High Pass filter.
Audio Input and Output
The EX26 uses a balanced, female XLR connector for
the audio input connector, and a male XLR connector
to provide through output signal. The through output
connector, wired in parallel to the audio input, will
continue to provide the input signal if the EX26 is
turned off. The audio input circuit presents a 20 kΩ
balanced input impedance to a three-pin XLR
connector with the following connections:
Main input
Through output
Pin 1 - Ground
Pin 2 - Signal (+)
Pin 3 - Signal (-) Case - Earth (AC) ground and chassis
Audio signal can be daisy-chained using the through output connector on the input panel. A single source can drive
multiple EX26 speakers with a paralleled input loop. If you are driving multiple EX26's make certain that the source
device can drive the total load impedance presented by the paralleled input circuits.
The audio source must be capable of producing a minimum of 1.0V volts rms to produce the maximum peak SPL over
the operating bandwidth of the loudspeaker. To avoid distortion from the source, make sure the source equipment
provides an adequate drive circuit design for the total paralleled load impedance presented by the speakers. The input
impedance for a single loudspeaker is 20 kΩ. If "n" represents the number of EX26 loudspeakers in a system, paralleling
the inputs of n loudspeakers will produce a balanced input load of 20 kΩ divided by "n".
If the loudspeaker produces noises such as hiss and popping, disconnect the audio cable from the loudspeaker,
if the noise stops, then most likely the problem is not with the loudspeaker. Check the audio cable, source,
and AC power for the source of the problem.
Ensure that all cabling carrying signal to multiple amplifiers and active speaker systems is wired correctly. Make
sure that the polarity has not been reversed. Reversed polarity can cause severe degradation in frequency
response and can also impact the dispersion characteristics of the speaker.
