the HIGH MID GAIN until you reach a desired blend, keeping in mind not to remove too much of that frequency, or the sound will be
unnatural. Usually a MID GAIN setting of 11:00, sometimes as low as 10:00, should remove enough of the unwanted frequencies.
LOW MID FREQUENCY provides control over frequencies between 150Hz and 1800Hz and these regions are responsible for the
“earthy” or “woody” character of the tone. HIGH MID FREQUENCY gives you a range of frequencies between 300Hz and 5000Hz to
work with and these frequencies are responsible for the “attack” or “biting” character of the tone. These are Active controls with boost
and cut controlled by the LOW MID GAIN and HIGH MID GAIN controls, the amount of boost proportional to the clockwise rotation
to the right of “flat” (12:00 straight up) position and the amount of cut proportional to the counter-clockwise rotation to the left of “flat”
(12:00 straight up) position.
NOTE: Keep in mind that with the GAIN control in the “flat” (12:00) position, there will be no difference heard when sweeping the
corresponding FREQ control to that because there is no cut or boost being applied in that band.
This style of control is referred to as a peak-dip (or bell) style filter. Here in the Rosette DI Pre, the pair that comprises the MID controls
offers accuracy and flexibility only found on fully professional recording or live sound mixing consoles. It may take a minute to become
familiar with the level of control and power they provide in shaping your sound, but if you start with the basic procedure outlined above,
you’ll be dialing in great tones for all your instruments with ease and confidence before you know it.
TREBLE
This active EQ control is responsible for the amount of high frequencies present in the signal, relative to the rest of the
spectrum. High frequencies above 5kHz are represented here and these are associated with the “bright”, “airy”, “shimmery” character
of the tone. This is also an Active control with boost and cut style power, the amount of boost proportional to the clockwise rotation
to the right of the “flat” (12:00 straight up) position and the amount of cut proportional to the counter-clockwise rotation to the left of
the “flat” (12:00 straight up) position. If the sound is perceived as too bright, thin or brittle, try turning this control down a bit. This is a
shelving style filter meaning that the frequency range covered is a bit broader and it is fixed rather than adjustable like the HIGH and
LOW MID Band semi-parametric style controls.
MASTER VOLUME
This control is responsible for the overall level of signal being sent to the PREAMP OUTPUTS, and deter-
mines the overall playing volume of the ROSETTE™ DI-PREAMP. Using the MASTER control along with the INPUT (GAIN) control
allows the optimal control over playing volume. For example, if you are using an instrument with a very high output level, it will be likely
be necessary to adjust the INPUT control a little lower and maybe the MASTER VOLUME control a little higher to obtain a reasonable
playing volume and to avoid overdriving of the input. Likewise, if you have an instrument with very low output level, it will be necessary
to turn the INPUT control up higher and maybe use a lower MASTER VOLUME control setting to obtain the desired playing volume.

OPERATING POWER REQUIREMENTS & POWER JACK
The ROSETTE™ DI-PREAMP is designed to operate from
either its internal 9 volt battery (alkaline is recommended), or from any standard 9VDC center “-“ (minus) power supply using a
standard 2.1mm center pin and 5.5mm outside barrel. The internal battery may remain in place as there is circuitry present that will
automatically select the external DC power supply when present. The internal battery is accessed by removing the cover from the
battery box, located on the bottom of the unit. The internal circuitry is protected against accidental battery and external power supply
