BehringerMods FAQ

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 2V rms (1V rms per phase or 2.8V peak differential). Single-ended connection 2V rms.

What is the input and output impedance of the BehringerMods circuits? The input impedance is 8K Ohms. The output impedance is 50 Ohms. To achieve a high signal to noise ratio, the output circuit throws a lot of current around, so the minimum recommended load not to cause overheating is 5K Ohms.

How can I connect the XLR inputs and outputs to RCA phono sockets? Balanced to single-ended conversion simply requires a custom made cable. Click here to see a wiring diagram. High quality RCA to XLR cables suitable for floating inputs and outputs can be purchased at the Online Shop.

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 equaliser 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 equaliser. e.g. If the equaliser applies a +6dB boost at 100Hz, it is recommended that the Gain setting be adjusted to -7dB (-6dB plus one for luck).

If the level meter LEDs are replaced with a volume control, how can I see the signal levels? The main screen can display numerous metering options. Simply press the 'Meter' or 'RTA' buttons. A digital clip indicator is also included above the volume control and responds to both input and output clipping. This makes it easy to detect when the Gain Offset control needs to be adjusted.

Does the Behringer DEQ2496 room correction work in the time domain? Yes, an explanation of how this works is available here.

How can I set-up Room Correction on the DEQ? BehringerMods have made a short video showing how to implement the automatic correction system of the DEQ. Watch it here. The DEQ2496 automatic room correction uses graphic EQ and while it works, it is not ideal. To achieve the best results, it is recommended that an external measurement system is used, such as a PC running Room EQ Wizard with an audio interface and omnidirectional microphone. The process is not automatic.

If the entire analog circuitry is replaced, 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 different 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.
