Why not simply use the standard DEQ with an external DAC? This is possible, however we are not aware of any
DAC with equal performance for the same cost as the modifications. The same is true of finding an external ADC with equal performance and cost.
What are the maximum input and output signal levels for 0dB full scale? Balanced connection
3V rms (1.5V rms per phase). Single-ended connection 3V rms.
What is the input and output impedance of the BehringerMods circuits?
The input impedance is 10K Ohm. The output impedance is 100 Ohm.
Recommended minimum output load is 1K Ohm.
How can I connect the XLR inputs and outputs to RCA phono sockets? Balanced to single-ended conversion simply requires an
adaptor or converter cable. Click here
to see a wiring diagram. There are two ways to connect the output.
What microphone do you recommend for measuring my room? The Behringer ECM8000 is the most affordable omnidirectional flat response mic we know about, however other 'measurement mics' will also work.
How can I avoid digital clipping? Most digital recordings peak at 0dBFS, the maximum possible level in the digital domain. This being the case, when the
equalizer is required to apply positive boost, the level is likely to clip. To maintain sound quality, it is important to adjust the 'Gain Offset' setting under the I/O menu on the DEQ, or the 'Gain' setting under the A&B channels on the DCX. This should be reduced by the amount of gain applied by the
equalizer. e.g. If the equalizer applies a +6dB boost at 100Hz, it is recommended that the Gain setting be adjusted to -7dB (-6dB plus one for luck).
Does the Behringer DEQ2496 room correction work in the time domain? Yes, an explanation of how this works is
available here.
On the DEQ, does the signal level switch still work? No, it doesn't. The outputs and inputs are fixed at the signal levels noted above.
Do the 'Aux' outputs of the DEQ benefit from the modifications as well? No, only the main inputs and outputs are improved, however the aux outputs still function as before.
Does 'Input C' on the DCX also benefit from the analog input mods? No, only the two main inputs are improved, however Input C still functions as before (with
original gain level).
Can you modify the clock, swap the DAC chip or change the power supply? No, we only offer the modifications detailed on the site. We have experience of modifying the Behringer DEQ and DCX over many years and know well which changes bring a worthwhile improvement.
