3.5Why an extensive bracing of the cabinet ?
The loudspeaker cabinet is very tall. Moreover, there are several vents for the speaker drivers on the front panel. As a result, transmission of vibrations from the drivers to the cabinet can hardly be prevented. However, to avoid such vibrations, stiffening ribs are optimally placed within the cabinet. By implementing this, admittedly, slightly extreme measure, we have succeeded in eliminating all vibrations.
3.6How works the digital volume and tone adjustement ?
Digital servo components are used to set volume, tone, and balance. They are nearly ever-lasting as they do not contain any mechanical parts. Furthermore, they are maintenance-free and very precise. Moreover, the intelligent software monitors and limits the volume level when the system is switched on in order to avoid an unpleasant surprise. You conveniently operate the system by using an IR remote control.
3.7Why several loudspeaker drivers ?
Due to the slim appearance and the pleasing design, it is not possible to use a large woofer with an accordingly large surface of the diaphragm. However, to achieve similar low-frequency foundation, the surface of the diaphragm is divided among several separate drivers. A big advantage of these relatively small woofers is that the smaller diaphragms have an increased dimensional stability. Additionally, special magnets reduce harmonic distortions, i.e. the non-linear distortion factor.
As the woofers cause air vibrations, a small enclosure is built into the loudspeaker cabinet in order to protect the mid-range driver from their influence. A specially built driver with extremely low harmonic distortion is used for the mid-range. The treble dome is equipped with a broadly radiating aluminum diaphragm. We have paid special attention to the weight of the coil and the diaphragm and reduced their weight as much as possible.
3.8Monitoring of electrical and thermal parameters
At Revox, the quality of the loudspeakers is permanently monitored. Each Digital- Active Loudspeakersystem undergoes a 14 hours burn-in test before shipment. To ensure that the electrical requirements are fulfilled, our manufacturing department works with sophisticated computer measuring equipment. And even when in operation, the loudspeaker is constantly monitored. The electronic unit permanently measures the temperature of the heat sink. If, for some reason, the heat sink overheats, the electronic unit shuts down automatically, and a LED lights up. Moreover, the power fed to the loudspeakers is constantly monitored. If the load is too heavy for a driver, it is reduced.
