[. . . ] EUROPOWER 2x700 WATTS POWER AMPLIFIER 2x1200 WATTS POWER AMPLIFIER EP1500/EP2500 User Manual A50-18333-00006 EUROPOWER EP1500/EP2500 Important safety instructions 1) Read these instructions. 8) Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. 9) Do not defeat the safety purpose of the polarized or grounding-type plug. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. [. . . ] Engaging and disengaging the filters is done by using the switches 3 (ch. As long as the filter is disengaged, frequencies below 5 Hz are cut to prevent damage. You should set up the filters so they best suit the frequency response of your speakers, since some speakers (e. g. bass reflex speakers) are particularly sensitive to over-excursion below the listed frequency range. The 50 Hz filter should be engaged when using broadband speakers because the filter provides a moderate amplification in the 100-Hz range, resulting in a fuller sound. The 30 Hz filter is ideally suited for subwoofer operation as well as for broadband cabinets. The "Off" setting should be used only for special applications (e. g. studio applications), in which recognizing and subsequently removing infra-sound is important. 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. There is always a separate input signal as well as a separate output signal. 2. 3. 3 2-channel mode (stereo) Both channels of your amp function independently from one another in this operating mode, and each has its own input signal. To activate this operating mode, please set the MODE SWITCHES 4 and 5 to "STEREO". + When running the unit in two-channel mode, the switches for mono-bridged mode must be disengaged (dip switches 6 and 7 in left position). Applications 7 EUROPOWER EP1500/EP2500 Examples: = 2-channel (stereo) playback = Two independent mono signals, e. g. instrument signal and monitor mix = Bi-amp operation, whereby bass frequencies are run on channel 1, and high frequencies on channel 2 (see chapter 3. 2 "Bi-amping"). Examples: = A mono signal is fed into both channels, whereby amplification of each channel is controlled separately. = 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. Fig. 3. 2: DIP switch positions for 2-channel operation 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. 3. 4: DIP switch positions for parallel operation When running in mono-bridged mode, the voltage of both channels is added up and fed into a single loudspeaker system. There is one input and one output signal respectively, and only the controls of channel 1 (and not of channel 2) are used.
