The NTBT-918 is a tone control preamp with fully independent Bass and Treble controls with very low noise and wide boost/cut range. It is 2/3 the size of a 9v battery.
The sound is very clear and transparent. Distortion is well below 0.001%. This preamp can be used with either 1 – 9 volt battery ( 9 volt operation) or 2 – 9 volt batteries (18 volt operation) which yields 6 dB extra headroom.
In 9 volt operation the NTBT-918 uses approximately 750 microamperes of current from 1 – 9 volt battery. This means 1 month of continuous duty or more than 6 months of average usage.
In 18 volt operation the NTBT-918 uses approximately 1000 microamperes of current from 2 – 9 volt batteries. This means more than 3 weeks of continuous duty or more than 4 months of average usage.
