Product Description
The DBX 234 Stereo 2/3 Way Mono 4 Way Crossover With Trs Balanced Conectors. Perfect for live concert and club sound applications, the 234 delivers accurate, wide-bandwidth and low-noise performance. For superior sound quality, the 234 features high-performance, 24dB per octave Linkwitz-Riley filters and DBX’s advance low-noise circuitry.
The DBX 234 Stereo 2/3 Way Mono 4-Way Crossover lets you choose 2-way, 3-way, or mono 4-way operation via 2 back-panel switches. A third switch lets you mono sum the LF output. Panel controls include left and right Channel crossover frequency selectors, output level controls and phase reverse/channel mutes switches. Front panel LEDs indicate when “x10” switches on the back panel are activated and whether the unit is in stereo or mono mode. Recessed 40Hz low cut (HPF) switches on each channel let you remove unwanted low frequencies for better system performance. All front panel rotary controls feature detent settings for more precise frequency and level adjustments.
