TRS differentially balanced ins and outs
The 234s features 1/4" differentially balanced inputs and outputs which help eliminate common mode noise problems that may arise
Mode switches for mono 4-way or stereo 2-way/3-way operation
Select either Mono 4-way or Stereo 2-way/3-way operation via the switches located on the 234s's rear panel.
Low frequency summed (subwoofer) output
Designed specifically for mono subwoofer applications, the 234s's LF sum switch “sums” the low frequencies of both the left and right inputs. The sum is sent to channel one’s low output marked “LF SUM”, while channel two’s low output is not used, and channel two’s phase invert led is disabled, indicating it is not operational in “LF Sum” mode. The summed low frequencies represent all the low frequencies of both the left and right inputs, and since lows are generally non-directional anyway, it will not detract from the true stereo picture of the source material.
x10 range switch on both channels
If you are using your system in stereo 2-way or 3-way mode, the needed crossover frequency may be higher than 960 Hz, making it necessary to set the x10 switch to the active position. This changes the range of operation of the frequency selector from 45-960 Hz to 450 Hz to 9.6 kHz. All other frequency selectors remain the same.
40Hz high pass (low cut) filter both channels
The 234s features a Low Cut Switch for selecting the 40 Hz high pass filter. An LED indicates the selection.
Phase reverse switch on all outputs
Every output is equipped with a polarity (Ø) reverse switch on the front panel. When speakers are not “in phase”, the frequency response of the system is compromised, particularly in the low frequencies. Out of phase signals can also cause “comb-filtering” in the high frequencies. The polarity switch is extremely useful for fine tuning your sound system for peak performance. An LED is activated when the output polarity is reversed.
Individual level controls on all outputs
Level controls are provided for the Low Output, High Output and Mid Output to dial in your system exactly as you want it.
24dB per octave Linkwitz-Riley filters (the professional standard)
The 234s features Linkwitz-Riley filters with (almost) perfect phase-coherency, and no peaks or dips at the crossover frequency.
Stereo/Mono status LEDs indicate the selected mode
Easily determine the stereo/mono mode status of the 234s via the front panel LEDs.
