AMPLIFIER CONFIGURATION
All EP series models include at the rear panel a group of
mini dips to configure different settings of the units.
These are the parameters accessible via rear panel of the
units:
- Amplifier GAIN (dB). By default is set to 35dB.
- Bridge or Stereo mode. By default is set to stereo mode.
- Maximum voltage available per output channel. This is
basically a limiter that allows the end user to reduce the
voltage produced by the amplifier to match the power
capacity of the audio systems. By default the amplifier is
set to its maximum capability.
- Hard or Soft limiting mode. When hard mode is enabled
the attack time of the limiter is shorter and allows less
peaks to be driven to the load.
Gain
Globally affects all channels. From + 23 dB to + 44 dB in
3dB steps.
Bridge
Switches the channel pairs into bridge mode. Valid for
channels A+B and C+D.
Voltage Limiters
Adjust (per channel) the maximum value of the desired
peak voltage accordingly to the audio system´s power
handling.

Input and Output connectors
All EP series models are equipped with 4x XLR input
connectors (one per amplifer channel). All models include
2x XLR output (loop thru of input channels A and C)
connectors are also available for daisy chaining multiple
amplifier channels using the same audio signal.
All EP series models are equipped with 4x NL4FC Speakon
Output connectors (Speaker Outputs), one per amplifier
channel.
Two amplified channels can be connected from a single
NL4FC connector (see figure below, CH A and B):
CH A and B
+-1 / +-2
CH C
+-1
CH D
+-1
When using a bridge configuration use pins +1 and -2 of
the NL4 connector in your cable.
