ART EQ355 EQ300 Series 31 Band Dual-Channel Graphic Equalizer

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 constantQ 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 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 that 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 nonequalized 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 3.5" for the EQ355. The depth is 7", exclusive of the 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 is 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.

• May be used in a variety of applications such as live sound, recording studios, instrument racks as well as any conventional fixed installation environment
• The equalizer can be used wherever modification of the frequency contour of a sound is needed
• The graphic equalizer is a powerful tool for solving a number of audio problems and creating interesting sound textures
• Patch the EQ between your mixing console and power amps to allow you to alter the overall mix to better match your environment
• Use the EQ between your monitor mixer and monitor power amps to aid in the removal of feedback inducing frequencies
• Patch into a channel insert to EQ one channel or track individually
• Run your instrument directly into the equalizer to enhance its sound before reaching a power amplifier or instrument amplifier.
• Patch into the effects loop of an instrument amplifier or between a preamp and power amp to have precise control over the complete sound
