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.

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.

The TCM 3 onboard preamp can be combined with both, active and passive pickups.
Please note that the standard balance potentiometer does not work with active pickups and must
be replaced by a low-resistance potentiometer  >> available on request for an additional charge!

All units are prewired with high flexible cables, all pots, jack and battery clip.
Knobs are not included in delivery..

Potentiometers have 6 mm solid shafts, while the stacked pot has 4 mm (upper) and 6 mm (lower)
solid shafts. Screwable knobs are required !

The following drill diameters are required for the potentiometers:
Volume(pp), bass, treble, midrange, balance, passive tone pot: 8 mm
Concentric(double) pots = volume(pp)/balance , bass/treble: 10 mm

Required electronic compartment depth: 27mm,
for configurations with concentric volume(pp) balance-Pot: 34 mm

Below you will find the TCM 3 electronics with various potentiometer configurations.

Further custom configurations are available on request.
