SWR Sound Natural Blonde PR 723 Instrucciones De Funcionamiento página 7

B . INPUT 2—This input accepts either an XLR or 1/4" plug:
The XLR connection is a balanced input:
(Pin 1=ground, Pin 2=positive, Pin 3=negative)
The 1/4" connection is an unbalanced "TS" input:
(Tip=positive, Sleeve=ground)
Use "Phantom Power" as required for microphones connected
to the XLR input (this button does not affect the 1/4" input).
Off—Phantom Power off.
On—Phantom Power on.
C . PAD/CLIP—PAD reduces input sensitivity by –10dB to provide
cleaner response with high output sources on each channel.
Select PAD if a CLIP LED illuminates, indicating signal
distortion.
NOTE: CLIP LEDs flashing simultaneously indicates that the Bass
Intensifier {M} or Master Volume {P} levels are clipping and
should be reduced. Channel 1 and Channel 2 CLIP LEDs flashing
independently indicates that the Gain {D}, EQ {G–K}, or EFFECTS
BLEND {L} levels for that channel are clipping and should be
reduced.
D . GAIN—Adjusts the preamp signal level for each channel.
GAIN is also the primary level control for the EFX SEND {X}
and LINE OUT {Y} jacks on the rear panel and can be used to
accommodate the input sensitivity of external equipment, if
necessary.
E . MUTE—Disables audio output from each channel except
TUNER OUT {W}, useful for instrument changes and tune-ups.
The LED indicates when MUTE is active.
F . PHASE—Press to reverse the phase of the INPUT circuit of each
channel, useful for reducing "regenerative" feedback when you
are standing at a particular distance from the amplifier. You can
also reduce feedback by changing your position or distance
from the amplifier.
G . AURAL ENHANCER— A trademark SWR® feature for over 20
years, the Aural Enhancer brings out the fundamental low
notes of the bass, brightens high-end transients and reduces
certain frequencies that "mask" the fundamentals. The ultimate
effect is a more transparent sound that opens up the sibilance
characteristics of all instruments without being harsh.
How the Aural Enhancer works: Think of it as a variable tone
control that changes frequency range AND level according to
where you set the Aural Enhancer control:
As you rotate the control clockwise from the "MIN" position,
you are elevating low, mid, and high frequency levels in ranges
that are different, yet complementary to the Bass and Treble
tone controls. The "2 o'clock" position—a favorite for many
players—brings out both low end fundamentals and crisp
highs, while at the same time, adds a little lower midrange
helping you to cut through the band. Then, as you rotate
further clockwise, selected mids will drop off—specifically, a
group of frequencies centered around 200Hz. While apparent,
the Aural Enhancer is gentle compared to the extreme response
curves you can create with the EQ tone controls.

EQ IN/OUT—Engages/bypasses the tone controls and the
Aural Enhancer for each channel, as indicated by the
and "brackets" on the front panel.
MID RANGE—Semi-parametric tone control for each channel.
These split knobs allow you to adjust mid-frequency range and
level. With the outer ring, select the frequency range that you
want to control from 400Hz to 2.6kHz, then use the inner knob
to adjust the amount of cut or boost at the selected frequency.
Mid range adjustment is critical for most instruments and
depends on your situation. What may sound harsh while
playing alone may sound just right in a crowded room, or on a
recording.
TREBLE—Adjusts high-frequency response ±15dB above the
3kHz range. This range adds bright sparkle to your sound.
Because high frequencies are inherently directional (narrowly
focused), it is important to listen from different angles to find
the best treble setting and the optimum placement for your
amplifier.
EFFECTS BLEND—Functional only when a plug is inserted into
one of the EFX RETURN {X} jacks, this knob sets your effects
level by controlling the amount of "wet" effects loop signal
blended into the "dry" preamp signal.
Intensifier circuit for both channels, as indicated by the
