BartoliniNTBT 2-Band EQ Preamp Module
Independent shopping perspective
The Korena take
Independent bass and treble controls make the NTBT a focused 2-band preamp for a clear, transparent, strong output with very low distortion. Its prewired gain trimmer can add up to 12dB, letting you align the instrument with another instrument's output or drive level-sensitive effects. Internal shielding and input filtering address electromagnetic interference and AM/FM radio, while the 9V or 18V power options accommodate the required headroom.
Strong match
Who this is for
- Matching an instrument's output level to other instruments or level-sensitive effects in a shared rig.
- Installing a 2-band preamp with connections for volume, battery, output jack, and EQ controls.
- Choosing 18V wiring when 6dB of extra headroom is required without a tonal change.
Consider the trade-offs
When to look elsewhere
- A single 9V installation does not have the 6dB extra headroom available from 18V wiring.
