UM TG12345CB-123121
Frequency Bands
The TG12345 Curve Bender has four frequency bands per
left and right channels— Bass, Presence 1, Presence 2, and
Treble.
The Treble and Bass bands are peak or shelf switchable.
Note:
Historic frequencies are marked in white, and modern
additions in gold.
Treble
The ‘TREBLE’ band on the Curve Bender is Peak or Shelf
switchable, featuring eight frequency selections (3.6, 4.2, 6.5,
8.1, 10, 12, 16kHz, and 20kHz) and an “OUT” or band by-
pass position.
Presence 1
The ‘PRESENCE 1’ or mid band on the Curve Bender is a
Bell type, featuring 8 frequency selections (.8, 1.2, 1.8, 2.8,
3.6, 4.2, 6.5, 8.1kHz) and an “OUT” or band bypass position.
Presence 2
The ‘PRESENCE 2’ or mid band on the Curve Bender is a Bell
type, featuring 8 frequency selections (.3, .5, .8, 1.2, 1.8, 2.8,
3.6kHz) and an “OUT” or band bypass position.
Bass
The ‘BASS’ band on the Curve Bender is Peak or Shelf
switchable, featuring 7 frequency selections (35, 50, 70, 91,
150, 200, 300Hz) and an “OUT” or band bypass position.
Note:
Beginning with the TG12345 MK.II desk, the low fre-
quency had a single shelving selection and the presence had
eight peaking selections. In the spirit of making the ultimate
TG EQ, we reproduced the curves of the shelving and peak-
ing bands so that the treble and bass sections can now use
the curves of each. I.e. You may now peak or shelf on the
bottom or top.
Historic frequency selections were as follows— .5, .8, 1.2,
1.8, 2.8, 4.2, 6.5, 10kHz, and low shelf at 50Hz.
