UM TG12345CB-123121
Boost/Cut and Multiply
Each frequency band features a boost/cut control, and an
x1/x1.5 multiply toggle switch.
Boosting or cutting of a selected frequency is achieved by
adjustment of the boost/cut control for the desired result.
The boost/cut control is stepped and l/-5.
For greater flexibility, the amount of boost/cut available is
influenced by the position of the x1/x1.5 multiply toggle
switch.
A setting of x1 provides both a wider Q curve and a boost/
cut of +/-5db in .5db steps.
A setting of x1.5 provides both a sharpening of Q curve and
a boost/cut of up to +/-13.5db.
Setting the x1/x1.5 multiplier switch to the center ‘OUT’ po-
sition, bypasses the band, allowing for quick AB listening of
the band without losing your frequency position.
Note:
The multiply toggle switch is not a frequency multi-
plier.
Revision Note:
Prior to 2011, there were two versions of
the TG12345 Curve Bender, Standard and Mastering. The
standard TG12345 Curve Bender offered boost/cut in 1db
steps and its controls were labeled for +/-10; mastering ver-
sions provided boost/cut in .5db steps. In late 2011, standard
and mastering versions of the TG12345 Curve Bender EQs
were combined into a single and more flexible unit.
Filters
The TG12345 Curve Bender EQ features both a high and
low-pass filter facility per Left and Right channel.
Historical Note
: The original Curve Bender and TG12345
console did not have high or low-pass filters; we thought it
was important to add them.
Although we selected our own frequencies, it is an important
fact that new circuitry was not invented to add this feature.
Simply put, appropriate circuits and amplifiers were bor-
rowed and slightly modified from existing TG amplifiers to
maintain authenticity throughout the unit.
High-Pass
The high-pass filter features
10 frequency options (20, 30,
40, 50, 60, 80, 100, 160, 200,
320Hz,) at a gentle slope, and
an “OUT” position to bypass
the control.
Low-Pass
The low-pass filter features 9
frequency options (30, 20, 18,
14, 10, 8.1, 5, 3, 2kHz,) at a
gentle slope, and an “OUT” po-
sition to bypass the control.
Tip:
Use the low-pass filter as
a way to create a great low-fi
drums sound.
