The NTBT-918 is a tone control preamp with fully independent Bass and Treble controls with very low noise and wide boost/cut range. The sound is extremely clear and transparent. Distortion is well below 0.001%.This preamp can be used with either a single 9 volt battery ( 9 volt operation) or two 9 volt batteries (18 volt operation) which yields 6dB extra headroom.

NTBT-918
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.The negative side of the battery(ies) should be connected to the jack ring so that power is turned on only when the plug is in. Unplug the instrument when not in use to conserve your battery.
