The new dbQ-zero matches the previous product in terms of its 30-band constant-Q graphic EQ section on each channel, plus a filter section consisting of high-pass filter, high and low shelving equalizers and two notch filters. Apex has focused on improving inter-channel crosstalk and THD+N figures, as well as load stability with the implementation of updated line driver circuitry.
The dbQ-zero also features a new design of chassis for enhanced ruggedness, as well as a new and intuitive user interface. Two 10-segment LED level indicators, each with dedicated signal and clip LEDs, offer improved peak meter stability at low frequencies.
To simplify connection of the dBQ-zero in any application - whether on the road or in a fixed installation - the unit offers XLR, 1/4" jack and screw terminal connections per channel. These are all electronically balanced, and bypass relays are also provided in the event of loss of power.
