OVERVIEW
The ART EQ300 Series of graphic equalizers have been designed and engineered to
extremely high standards for audio performance and functionality. These innovative,
high-quality equalizers are perfect for virtually any audio application where precision
frequency tailoring, reliable performance, rugged design and extremely silent
processing is important.
Active Filter Sections
The EQ300 Series of graphic equalizers feature
active filter sections, which incorporate a constant-
Q design. This constant-Q design, with accurate
precision center frequencies), ensures that the
bandwidth of every individual filter will be narrow
enough to prevent unnecessary interaction
between filters, yet still create an equalization curve
wide enough to produce the exact and precise
processing of audio frequencies the user seeks.
Precision Slide Potentiometers
The EQ300 Series of graphic equalizers utilize
20mm precision slide potentiometers. These
center-detented, precision faders are graphically
positioned on ISO center frequencies between
25Hz-16kHz for the EQ341, 20Hz to 20kHz for the
EQ351 and EQ355.
Independent Variable Hi and Low Pass Filtering
In order to deliver superlative performance and
control, the EQ351 and EQ355 graphic equalizers
incorporate independent variable Hi Pass (low cut)
and Low Pass (high cut) filters. Having separate
and variable precision control for both the Hi Pass
and Low Pass filters, allows the user to custom
tailor the audio signal to perfection.
Many competing products only feature shelving
switches which have a fixed frequency point.
Others do not have separate filtering for both high
and low frequencies. These designs do not offer
the precision or control of the ART EQ300 Series.
Additional Controls and Indicators
The EQ300 Series of graphic equalizers utilize a
variable output level control, clip level indicator,
ground lift switch, and selectable line voltage.
Additional features include selectable scale
switching - high slider resolution (±12dB) or normal
resolution (±6dB), active balanced and unbalanced
input/output connectors, and RFI filtering.
A passive bypass switch allows for direct
comparison between the equalized and non-
equalized signal for each channel.
Multiple Connectivity
The EQ300 Series of graphic equalizers can be
connected with a wide variety of audio devices.
Each unit has three sets of input and output
connectors wired in parallel. These connections
include XLR connectors, 1/4" phone jacks and RCA
phono jacks.
Durability by Design
The EQ300 Series of graphic equalizers are
designed and engineered to be durable and
rugged. They are an ideal choice when the need for
a robust equalizer is of paramount concern. They
are designed for mounting in a standard 19"
equipment rack or one of the many rack-type
portable cases in existence. The vertical height is
1.75 inches for the EQ341 and EQ351, and 3.5
inches for the EQ355. The depth is 7 inches,
exclusive of power cord.
Rugged construction and solid audio performance
make these equalizers particularly well suited to
fixed installation as well as touring live sound
systems.
Precision and Quality
When considering quality equalization, the ART
EQ300 Series of graphic equalizers are an
excellent choice. They deliver extremely precise,
powerfully flexible and simply great sounding
equalization, with the quality features and reliable
design necessary for top-level audio performance.
