Interference with nearby electrical devices due to magnetic fields! The device generates strong magnetic fields that can interfere with the function of poorly shielded devices. The magnetic fields are strongest directly above and below the Power Amplifier. You should therefore never place sensitive devices such as pre-amplifiers, radio transmission systems, or tape decks directly above or below the Power Amplifier. When placing the Power Amplifier in a rack, you should place it at the bottom thereof, and place any other equipment at the top of the rack. The following section explains the possible operating modes of the device. Channels 1 and 3 are marked there with "A" and channels 2 and 4 are marked with "B". 12 E4-130, E4-250 Power Amplifier Installation and starting up Available operating modes Stereo mode Parallel mode Bridged mode Depending on the individual application, the amplifier can be used in different operation modes: Both power amplifier channels operate independently of each other, each input (A and B) is amplified by one channel, speakers are connected to both power amplifier channels, the volume for both outputs can be controlled separately. Both power amplifier channels amplify the signal from input A, speakers are connected to both power amplifier channels, the volume controls of channels A and B are used to control the volume. Both power amplifier channels are internally wired to provide double the output power. Only the signal from input A is amplified, speakers are only con- nected to the accordingly labelled output. The controls for channel A and channel B are used to adjust the volume. The phase of the second or fourth channel is reversed. The speaker must be operated using a Y-adapter cable to CH1 1+ to 1+ and CH2 1+ to 1, see figure below.

If you want to connect multiple speakers to one amplifier output, note the following: n When speakers are connected in series, the impedances add up. n When speakers are connected in parallel, the reciprocal value of the total impedance is equal to the sum of the reciprocal values of the individual impedances. For the example of two speakers with the same impedance, this means: In series connection, impedance is doubled. In parallel connection, it's halved. Detailed information on this topic can be found in our online guide "Speakers" (www.thomann.de). 14 E4-130, E4-250 Power Amplifier Rack mounting Installation and starting up The device has been designed for rack mounting in a standard 19-inch rack; it occupies two rack units.

Please note these advices, because especially in `Sound & Light' caution is indicated: Even if a plug fits into the socket, an incorrect connection may result in a destroyed power amp, a short circuit or `just' in poor transmission quality! Balanced and unbalanced trans- mission Unbalanced transmission is mainly used in semi-professional environment and in hifi use. Instrument cables with two conductors (one core plus shielding) are typical representatives of the unbalanced transmission. One conductor is ground and shielding while the signal is trans- mitted through the core. Unbalanced transmission is susceptible to electromagnetic interference, especially at low levels, such as microphone signals and when using long cables. In a professional environment, therefore, the balanced transmission is preferred, because this enables an undisturbed transmission of signals over long distances. In addition to the conduc- tors `Ground' and `Signal', in a balanced transmission a second core is added. This also transfers the signal, but phase-shifted by 180°. Since the interference affects both cores equally, by subtracting the phase-shifted signals, the interfering signal is completely neutralized. The result is a pure signal without any noise inter- ference. 24 E4-130, E4-250 Power Amplifier XLR plug (balanced) XLR plug (unbalanced) Plug and connection assignment 1 Ground, shielding 2 Signal (in phase, +) 3 Signal (out of phase, ) 4 Shielding on plug housing (option) 1 Ground, shielding 2 Signal 3 Bridged to pin 1 E4-130, E4-250 Power Amplifier 25 Plug and connection assignment Speaker Twist connector # 1, + 1, 2, + 2, ö Signal 1 (in phase) Signal 1 (out of phase) NC (not connected) NC (not connected) 26 E4-130, E4-250 Power Amplifier 8 Cleaning Fan grids Cleaning The fan grids of the device must be cleaned of any contamination, such as dust, etc. on a reg- ular basis.
