Active Crossover Linkwitz-Riley Crossover
310Hz / 3.1kHz -24db/Oct 3 channels
This three-channels crossover uses a Linkwitz-Riley filter. A technology particularly appreciated for its remarkable performance in complex and multi-channel crossover systems.
Offering 4th order attenuation (-24dB per octave) while providing extremely flat phase response across the entire 20Hz-20kHz band, this is an ideal solution for effectively filtering your signal before injecting it into a power amplifier or active speakers.
Crossover points: 310HZ / 3.1KHZ (i.e. 20HZ-310HZ on bass output 310-3.1KHZ on medium output, 3100-20KHZ on treble output)
Digital display and equalization
On its front pannel, this filter / crossover has a digital display indicating the level of each output (bass / medium / treble) as well as the general volume of the device. Each parameter can be changed independently with ease using a push / turn knob.
Each output is available on an single ended stereo RCA port and can easily be interfaced in input as in output with a wide range of audio devices.
Integrated regulated linear power supply circuit
In order to offer a clear and reliable signal over the entire audio spectrum, the device has no less than two transformers mounted on a printed circuit for a total of 30W of power. Each channel of the stereo circuit thus benefits from its own regulated linear power supply stage and is isolated from competing signal sources in order to preserve as much as possible the stereophonic image and the separation of the channels.
Included remote control
Supplied with its remote control, the device can be controlled from a distance very comfortably.
Although rudimentary, this remote control allows you to control all the filter functions, which allows the user to position himself freely in the listening room when setting the levels of each of the three outputs.
