WHARFEDALE-PRO LMX204 Stereo Two-Way Crossover เครื่องตัดแบ่งความถี่เสียงลำโพง

he XO-204 is a 2 way stereo analogue active crossover that allows for the most simple and safe setup of a bi-amplified system.

The crossover frequency is sweepable from 60Hz to 1KHz providing an ideal frequency split suitable for feeding subs and full range units with discrete bandwidths right out of the box.

If you wish to use the XO-204 to split the programme material in a manner that is suitable to feed the mid and high drivers in a bi-amp compatible full range unit the X10 switch conveniently raises the crossover frequency to allow for this.

Emphasis has been placed on the safety of your rig with a switchable 40Hz 12dB/octave HPF to increase headroom and independent switchable soft limiting on each of the bands to protect your amp and speakers.

To help fine tune the setup of your system there are mute switches for each of the bands and also independent polarity switching.

The XO-204 active crossover has independent output level control ranging from -infinity to +6dB, to assist you there are LED output meters and a simple input clip LED.

All inputs and outputs are on balanced TRS jacks and there is the inclusion of a mono summed LF output for using a mono subwoofer in a stereo situation. The XO-204 comes in a 1U 19” rackmount chassis and accepts mains power via an IEC connector.
