Frequently asked questions
Which preamp is quieter?
The BQC HZ has a superior input-referred noise floor of -120dBV compared to the BQS at -96 dBV, making it better for quiet recording environments. However, the BQS output impedance of 200 Ohms is lower than the BQC HZ at 2K Ohms, which aids cleaner signal transmission overall.
How much longer does the BQS battery last?
The BQS draws only 1.5 milliamps at 9V for 170-hour battery life, while the BQC HZ at 9V draws 600 microamps but achieves 750 hours at 18V operation. At matching voltages, the BQS is more efficient for 9V use.
Can I use either preamp with non-HZ pickups?
The BQC HZ is specifically designed and optimized for EMG HZ passive pickups. The BQS System works as a general active preamp for EMG pickups and is not restricted to HZ models, making it more versatile across different pickup types.
Which has more user-friendly controls for live performance?
The BQS features a 5-knob layout with center detents on all EQ and balance controls, allowing you to feel your way back to neutral settings on stage. The BQC HZ uses a stack design that requires more precise visual adjustment, making the BQS better for live tweaking.
