The EX6 Control Panel
The EX6 features an easy to use control panel
featuring AC power in, audio input and output,
level control, LED status light and a High
Pass filter.

Audio Input and Output
The EX6 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 EX6 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 EX6 speakers with a paralleled input loop. If you are driving multiple EX6'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 0 dB (0.775V 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 EX6 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.
