NOLL TCM 3 active 3-band bass electronics

The NOLL TCM 3 is a compact equalizer that provides easy and space-saving installation.
The secure insulation of the sealed equalizer perfectly protects other electrical components.

Bass, midrange and treble controls are center-detented and allow 15dB of boost and cut with
a gentle slope of 6dB per octave which results in a natural and true sound.

The low impedance output of TCM 3 provides other great features.
You can run a cable up to 100 feet (30 m) without losing high frequency response.
