6.3 Input signal connections
The signal input connectors are of EUROBLOCK (12, 13) and electronically balanced. The
pin assignment is as follows:
• Hot or direct signal > +
• Cold or phase inverted signal > -
• Ground > Ground
For unbalanced connections, ground the negative terminal on the Euroblock.
In balanced mode, the input impedance is greater than 20k

(10k

unbalanced), allowing
you to connect a large number of stages in parallel without compromising the sound
quality.
6.4 Power saving mode
The AUTO STBY (10) switch allows to activate the automatic switching circuit calling the
power saving mode (low power consumption) when it detects no audio signal from the
unit's inputs during more than 90 seconds, and automatically recovering normal
operation when that signal reappears
6.5 Limiter circuit
This is an extra protection always enabled in the eGPA series amplifiers. This circuit
dynamically limits the input signal to avoid clipping of loud signals at the amplifier
output; it automatically reduces the input level not to exceed approximately 5%
distortion.
The great utility of this circuit in any type of installation should be noted; the advantage
of this system over traditional compressors is that dynamics is practically not altered, due
to its time constant.
