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 Volume (Push-Pull Active/Passive), Blend control, jack, and battery clip. The concentric Treble/Bass, and concentric Lo Midrange/Hi Midrange controls are prewired with high flexible cables.
Please Note:
Some soldering for Volume and 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.
