2.2.4 Enhancing the Sound of Tape Duplication

Even under the most favourable of conditions, presence, liveliness and transparency of the program material will suffer during each copying process. These losses are particularly obvious when copying cassettes while simultaneously using a noise reduction system.

With the BEHRINGER DUALFEX PRO, losses during tape duplication can be avoided or compensated for. Provided that the original is of good enough quality with only low noise levels. It is even possible to produce “super” copies which sound even better than the original.

For this purpose, the BEHRINGER DUALFEX PRO is inserted between the line outputs of the source machine and the inputs of the target machine. Machines with post-head listening control (setting “tape”) allow you to check the quality of the copy while duplicating the tape.

+If the tape noise is fairly high, a different strategy is required, since the BEHRINGER DUALFEX PRO can effectively process the frequency ranges in which the most predominant noise portions can be found. We recommend attenuation of noisy high frequencies, either with an equalizer or—better still—with a “single-ended” noise reduction system. The BEHRINGER DUALFEX PRO will process those frequencies with all their natural clarity—but without the tape noise.

2.2.5 Enhancing the Sound of Instruments

The bandwidth of most electronic musical instruments is limited by its “sampling rate”. The BEHRINGER DUALFEX PRO can improve the sound, so that synthesizers, samplers and drum machines have a more natural and transparent sound.

With the BEHRINGER DUALFEX PRO even tiny details within the sound of acoustic musical instruments (e.g. acoustic guitars) can be emphasized without affecting the overall sound of the instrument. Percussion instruments, such as toms or bass drums, benefit from being processed by becoming more powerful, precise and defined.

Please note that low-level signals, such as from microphones or guitars, should be run through a preamplifier before the processing stage, since the BEHRINGER DUALFEX PRO is a line-level device (-20 to +10 dBu).

2.2.6 Enhancing the Sound of PA Systems

If used in PA and other sound reinforcement systems for background or live music, the BEHRINGER DUALFEX PRO offers astounding advantages:

1.In audio systems for announcements and background music, the BEHRINGER DUALFEX PRO is placed in a similar way to recording and tape duplication - directly before the power amp. The intelligibility and range of your system will be improved and the sonic image will become clear and transparent, even at low volume levels. Problems caused by background noise fluctuations, room acoustics (reflections), and speaker setup can be solved more easily. For instance, in discos or clubs you do not need to constantly readjust the high frequencies as the place becomes increasingly crowded; you will be able to protect your speaker system and the hearing of visitors. Background music in bars and restaurants can be heard easily. It does not annoy your guests because its volume had to be turned up too far.

2.The sound of any PA system will be improved by using the BEHRINGER DUALFEX PRO. For example, the vocals of music groups or speech transmissions will be considerably more transparent and intelligible, the instruments can be distinguished more easily. The bass will gain in “depth” and power.

The BEHRINGER DUALFEX PRO will increase the speaker systems’ acoustic performance and its ability to penetrate a room, particularly in places with difficult acoustics. The system also needs less effective amplifier power, since the subjectively heard volume level increases. Powerful and detailed sound reproduction can also be achieved in “weak” systems. It helps that you do not have to spend a small fortune on upgrading your system.
