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.
