BWA-4
Reduces back electromotive force generated at speaker terminals and improves sound quality.
If you use a jumper for a speaker that supports wire interconnects, the importance of the wire is lost and the sound quality and phase characteristics are degraded due to the back electromotive force and unequal cable length. The purpose of the BWA-4 is to eliminate jumpers and distribute them evenly across the woofer and tweeter terminals, eliminating the effect of the back electromotive force and achieving accurate phase characteristics. Distortion and haze are significantly reduced and the sound image is localized with high transparency and resolution. An epochal design in which mirror-polished brass is plated with silver + rhodium and then treated at an ultra-low temperature of -196°C to maximize conductivity, and a guralmin cap also has a damping effect. is. With perfect conductivity properties and damping effect, we have been able to positively improve the sound quality, although there is no deterioration in continuity. A cable with a Y-end can also be connected for input. In contrast to expensive interconnect wiring, the actual quality can be improved.
● Cable insertion hole on the input side: Inner diameter Φ4.3 mm ● Cable insertion hole on the output side: Inner diameter Φ5.9 mm ● Y-end can be connected to the input side (Y-end inner diameter Φ8 mm or more).
Expensive jumper wires are pointless!
Nowadays, many speakers use two-wire compatible input terminals. This is to avoid the opposing electromotive force generated from the low frequency side due to the amplitude movement of the woofer, which would flow to the high frequency side and degrade the sound quality. Originally, two power amplifiers are used for the low frequency side and the high frequency side. The correct way to wire them is to drive the side separately with a bi-amp drive, or to connect the amplifier side to the low frequency side and the high frequency side separately with two sets of speaker cables, but this fact is unexpectedly familiar. There seems to be a lot of things that aren't there. Unaware of this fact, even trade magazines recommend interconnecting the high and low frequency sides as crossover, and some cable manufacturers release expensive interconnect cables that are completely nonsensical. This is why. For bi-wire compatible speakers, it is correct to eliminate the jumpers and connect two sets of speaker cables separately for the woofer side and separately for the tweeter side and exhibit the original speaker performance. In recent years, however, speaker cables have become more expensive and those who cannot afford to buy two sets of speaker cables or who have only one set of speaker terminals on the amplifier side connect two sets of thick speaker cables. However, some people can't do this. The BWA-4 two-wire adapter solves this problem. By cutting off the tip of the speaker cable you are currently using by about 30 cm and reconnecting it to the low frequency side and the high frequency side separately from the BWA-4, the electromotive force prevention effect is very close to a pure by-wire connection. You can get it.
Data on electromotive force feedback reduction by "BWA-4"
The 50Hz, 100Hz, 200Hz tone discharge signals were reproduced and the back electromotive force flowing into the high frequency side terminal was measured. And it uses a two-wire adapter BWA-4
B is connected to the connection board
C uses a high quality jumper wire * The magnitude of the reverse electromotive force is almost the same between the connected jumper plate and the high quality jumper wire, but dramatically decreases the reverse electromotive force with "BWA-4".
Maximum conductivity that does not cause deterioration in sound quality!
To prevent sound quality deterioration by inserting the adapter in the middle of the speaker cable, "BWA-4" adopts measures to improve the continuity performance to the highest possible degree. The material is lead-free brass with high conductivity, rhodium-plated, gold-plated double screw that does not deteriorate conductivity, such as soldering and crimping, and the cable's secure fastening method and treatment at ultra-low temperature of minus 196 °C improves conductivity. Improving.
Insulating tube is also included
The BWA-4 comes with an insulating tube to prevent the + and terminals from touching and shorting. If the + -terminals are too close together and there is a risk of them coming into contact with each other, be sure to cover them with the insulating tube.
Vibration control design that improves sound quality!
Combining an aviation-grade 2017S aluminum alloy enclosure, the BWA-4 has a damping effect by combining dissimilar metals with the brass of the main body. This vibration damping structure allows for rapid damping of vibrations transmitted from speaker terminals and speaker cables, further improving sound quality.
