The NOLL TCM 4 XM is a compact equalizer that provides easy and space-saving installation.
The secure insulation of the sealed equalizer perfectly protects other electrical components.

Bass, low midrange, high 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.

Active/passive-switch by volume(push-pull)-pot.

The equalizer is 9-Volt battery powered, adding an additional 9-Volt battery (18V) will ensure
more headroom.
