Cable Bridge, Bi-Wiring and Bi-Amping: Clearly Explained

Cable Bridge, Bi-Wiring and Bi-Amping: Clearly Explained post thumbnail image

Hi-Fi purists are always discussing different ways to get the best possible Hi-Fi sound. Anyone who turns to the Internet for advice on creating the perfect Hi-Fi setup may be faced with some questionable advice. Some tips may sound useful, but actually have little or no effect on sound quality, such as bi-wiring and using a cable bridge. But don’t worry, we know the real tricks to improve your Hi-Fi sound.

bi-wiring – to keep things organized

anyone who understands Learn the basics of bi-wiring it’s all about separating different sequences into different cables, So with bi-wiring it’s about two wires per speaker, with tri-wiring it’s three, and in some rare cases, you can even have four separate wires. Now people are probably asking the question of what is the point of this drama, when in reality only one cable per speaker is enough.

Distortion free sound thanks to frequency separation?

Reason behind the idea:

When transmitting a signal from an amplifier to a loudspeaker, all signals must be routed simultaneously through a single cable. Now there are people who look at the whole thing as purely physical and claim that the thickness of the cable depends only on the length (distance loudspeaker/amplifier) ​​and the impedance of the loudspeaker. As with other hi-fi fans, some experts are of the opinion that the more space you leave for the signal, the more it reaches the speaker without getting bogged down. One of the reasons for this is strong bass frequencies: basses will cause a stronger current to flow and their electromagnetic field will affect the treble and mid-range. This effect can be mitigated by isolating the bass and mid and high frequencies cable wires. The result will be a more balanced sound.

tri-strings – rise

With popular bi-strings, bass frequencies, as well as treble and mid-range frequencies everyone is their own cable, With tri-wiring, each frequency range is also routed through its own cable. HiFi fans are still arguing about whether it really brings a benefit and what exactly that benefit should look like. So if you have the right Hi-Fi components, you can try bi-wiring and see for yourself. However, it is important that the Hi-Fi components are designed for this: the amplifier must have at least two connections per speaker channel. The loudspeaker should also have a suitable connection, as shown in the figure:

Loudspeaker Bridges – Do You Need a High-End Cable Bridge?

In the picture, you can see the back of the Altima 40 MK2. The small gold plated metal clamps are the speaker bridge. You can find these on current models of Ultima 40, They are standard and always installed so if you want to do bi-wiring you will have to remove them. If that’s not what you’re after, leave the cable jumpers in place and they’ll bridge the signal between the two speakers.

From loudspeaker bridge to jumper cable

But here too there is room for improvement for the HiFi fan. However, like bi-wiring, no measurable difference can actually be determined, High quality cable bridges are still very popular, A cable bridge is basically nothing more than a very short HiFi cable that is used instead of a speaker bridge. These are mostly high-quality cables, usually gold plated connectors are used.

Significant sound improvement should be possible

As is often the case, hi-fi disciples have differing opinions, but many experts agree that a good cable bridge will make a noticeable difference in sound – speaking of a significant improvement in sound, More brilliant high and more powerful mid. The market for hi-fi cable bridges proves that these opinions cannot be completely taken off the air. These are available in various designs and price ranges. Cable bridges are available from around 30 euros to several hundred euros. Some representatives reach or shoot beyond the 1,000 euro mark in terms of price – especially with HiFi cables and thus hardly any limits on top even with cable bridges.

Bi-amping – a separate amplifier just for bass?

Another approach, which also involves splitting the frequencies, is bi-amping. As you can tell from the name, it is about the use of two amplifiers within a Hi-Fi system. This does not mean using the pre-amplifier and power amplifier separately, but each frequency range is actually assigned its own amplifier – this is called horizontal bi-amping.

Horizontal Bi-amping

In practice, this means that you need two stereo power amplifiers and a way to split the different frequencies before the power amp. To do this, you need a preamplifier or a special crossover, the so-called active crossover. A traditional crossover, as built into the speaker cabinet, doesn’t work. An active crossover usually has various setting options and can split frequencies into four different channels.

But very few people go that far, at least in their living rooms. However, this process is common practice for a large PA system. However, HiFi purists are more likely to encounter horizontal bi-amping with the pre-amplifier or active crossover described above. Compared to bi-wire, this method is not very common, which is undoubtedly due to the much higher cost.

Vertical Bi-amping

Another method for bi-amping is vertical bi-amping. Here every frequency range gets its own amplifier, not every loudspeaker. In the following video, it is explained in more detail. experts recommend rather Vertical bi-amping. Here you can read more about bi-amping.

    Conclusion: All a question of faith

    Although there is no measurable difference in sound quality with the use of bi-wire and high-quality cable bridges, many experts believe it can improve the sound. This phenomenon suggests that music and sound perception cannot always be explained scientifically. Perhaps, for once, you should trust your ears, not science. After all, scientists have already claimed that the human ear can’t separate an MP3 file by shrinking it to ten percent of its original size – hi-fi experts can only laugh about that.

    Therefore, it would be almost reckless to assume that such measures would be of no use in principle. Whether this is really a great improvement is a matter of debate. Therefore, the opinions of opponents of noble cable bridges and by-wiring are understandable. After all, such devices cost a lot of money, especially since bi-amping is an expensive affair. So once again you have to decide for yourself whether you want to invest in small but good sound improvement.
