[. . . ] 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. 5) Do not use this apparatus near water. 7) Do not block any ventilation openings. Install in accordance with the manufacturer's instructions. [. . . ] The reproduction of the signal's bass portion is thus optimized, since ultra-low, distracting frequencies are eliminated, and more power is available for the reproduction of the wanted segment of the signal. 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. Both channels operate fully independently from one another. 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. Two independent speakers are connected at the outputs. 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. [. . . ] Damage/defects caused by the following conditions are not covered by this warranty: = improper handling, neglect or failure to operate the unit in compliance with the instructions given in BEHRINGER user or service manuals. = connection or operation of the unit in any way that does not comply with the technical or safety regulations applicable in the country where the product is used. = damage/defects caused by force majeure or any other condition that is beyond the control of BEHRINGER. Any repair or opening of the unit carried out by unauthorized personnel (user included) will void the warranty. [. . . ]
