EUROPOWER EP1500/EP2500

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.

3.1Differences 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:

s2-channel (stereo) playback

sTwo independent mono signals, e.g. instrument signal and monitor mix

sBi-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:

sA mono signal is fed into both channels, whereby amplifi- cation of each channel is controlled separately.

sParallel 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.
