FBX4.4

FBX4.4 parameters:

This machine adopts new DSP digital processor technology, which is characterized by fool-like operation, fully automatic anti-howling, high sound quality restoration, and easy to solve the trouble of generating sound feedback due to the use of microphone.

Suitable for: conference rooms, multi-function entertainment halls, small and medium-sized performances, KTV rooms, home theaters.

◎ 4-in and 4-out design.

◎ Multi-type sockets for input and output, XLR and 6.5 can be selected for use.

◎ Automatically enter the anti-howling mode after booting.

◎ 4 channels corresponding to input and output, the input uses a new multi-function socket, including (CANNON) XLR and 6.5

◎ Using American DSP chip, applying digital processing system

◎ Has dual DSP and 68 filter points full automatic scanning.

◎ 1 and 2 channels use one DSP processor to set 68 filters for distribution.

◎ 3 and 4 channels use one DSP processor to set 68 filters for distribution.

◎ Automatic dynamic filtering to prevent howling, anti-howling starts without affecting the sound quality.

◎Every time the notch is activated to suppress howling, the balance will be restored after 2 seconds.

◎This machine has a critical point automatic pressure limit function. In order to prevent signal overload from causing distortion or damage to the device, when the sound is too loud, while suppressing howling, the pressure limit starts to suppress part of the sound, which can prevent damage to the speaker device.

◎When the volume returns to normal, the pressure limit will slowly recover. Under normal use, the pressure limit function does not start and does not affect any use.

◎The one-key gain function on the rear panel increases 12db when starting.
