EUROPOWER EP1500/EP2500
3. APPLICATIONS
3. APPLICATIONS
+ Running EUROPOWER amplifiers in conjunction with
8-Ohm speakers with a power rating of at least 2 x
260 Watts (EP1500) and 2 x 450 Watts (EP2500) is
recommended to assure optimal operation.
3.1 Differences between 2-channel, parallel
and mono-bridged operating modes
2-channel mode is the most common operating mode of
amplifiers. Both channels operate fully independently from one
another. There is always a separate input signal as well as a
separate output signal.
Examples:
s 2-channel (stereo) playback
s Two independent mono signals, e.g. instrument signal and
monitor mix
s Bi-amp operation, whereby bass frequencies are run on
channel 1, and high frequencies on channel 2 (see chapter
3.2, Bi-amping).

Parallel mode is identical to 2-channel mode, except for the
inputs of both channels are internally connected in parallel. One
input signal routes parallel both channels, while their filters etc.
are independently controlled.
Examples:
s A mono signal is fed into both channels, whereby amplifi-
cation of each channel is controlled separately.
s Parallel mode (as described above) with connection of an
additional amp via the remaining free input connector. The
input signal is present there, and may be connected to
further equipment.
+ When connecting a balanced input signal, please
make sure to exclusively use balanced cables for
passing the signal further on. Otherwise, a single
unbalanced cable can turn the entire signal
unbalanced.
