The Loudspeaker cables should be connected to the PHOENIX output connectors. Channel numbers and
the polarity are labeled on or next to the connectors.
For 100 Volt applications, the speaker output connections may be connected to a transformer package
Trapack 1, Trapack 3 or Trapack 5. See table below.

* Note: ENTERO 8100 used in 4 channels Bridge mode, max load is 260Watt per channel
** Note: ENTERO 4250 used in 2 channels Bridge mode, max load is 500Watt per channel
Two mode-select DIP switches on the rear of the amplifier can be used to select the operation modes
PARALLEL and BRIDGE (ENTERO
amplifier channels are in the regular STEREO mode.
In the Stereo operation mode, each channel will work independently from each other. Input connector 1
will generate signal on output connector 1 and so on.
If EQ cards are required, see chapter 10.5; each channel needs its own EQ card.

Both inputs of the channel pair must be fed with the same signal by connecting the input cable parallel
to both input connectors.
If EQ cards are required, see chapter 10.5; each channel needs its own EQ card.

For parallel operation, turn the amplifier off and set the mode select switch of the chosen power
amplifier pair to the PARALLEL position. Both channels are then driven by the signal connected to the
first channel of the pair (channel 1 and 2 by input 1, channel 3 and 4 by input 3).
Only the inputs of channel 1 and 3 are active, channels 2 and 4 are out of circuit.
If EQ cards are required, see chapter 10.5; each channel needs its own EQ card.
