2-Pickup 4-Band System
TCM 4 XM
The NOLL TCM 4 XM is a compact equalizer that provides easy and space- saving installation.
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.
The TCM 4 XM includes the concentric Volume (Push-Pull Active/Passive)/Blend control, jack, and battery clip. The Treble, Bass, Lo Midrange, and Hi Midrange controls are prewired with high flexible cables.
Some soldering for concentric Volume/Blend are required. Knobs are not included.
This equalizer can be powered with a minimum 9-volt battery, or 18v to ensure more headroom and longer battery life.
The NOLL TCM 4 XM can be combined with either active or passive pickups.
Potentiometers have a 6mm solid shaft, while any stacked control has 4mm upper, and 6mm lower solid shafts.
This preamp is recommended for a 4-knob control layouts.
The low impedance output of the TCM 4 XM provides other great features. You can run a cable for up to 100 feet (30 m) without losing high frequency response.
