ART 351 Single Channel 15 Band EQ
January 16, 1997
Applied Research and Technology is proud to introduce the 351 Single Channel 1/3 Octave Graphic Equalizer.
The 351 Graphic Equalizer is a powerful tool for solving a number of audio problems and creating interesting sound textures. The 351 features constant Q circuitry with a 3% center frequency accuracy, 20mm center dent sliders, selectable cut/boost range of 6db or 12db, active balanced and unbalanced input and output connections, adjustable high pass filter, adjustable low pass filter, variable input level control, clip level indicators, ground lift switch, internal power supply and selectable line voltage switch. A range control switch is provided allowing you to set the maximum boost or cut for each band of equalization to either 6db or 12db.
The high pass filter rolls off lower frequencies, which is useful for decreasing rumble or low frequency hum from a signal. Its range is adjustable from 10Hz to 250 Hz. Frequencies below this setting are rolled off' while frequencies above are unaffected. The low pass filter rolls off higher frequencies, which is useful for reducing hiss or siblance from a signal. Its range is adjustable from 3kHz to 40kHz.
The 351 has a bypass switch with LED indicator. The rugged, all-steel constructed chassis occupies 1U rack space and is intended for installation in standard 19" equipment racks.
Multiple input and output configurations are provided for ease of use and incorporate paralleled connections. The XLR and 1/4" TRS connectors use active balanced, low noise circuitry, and may be used in an unbalanced configuration. The RCA jacks are unbalanced. The input level control covers a wide range and can easily accommodate -10 and +4 signal levels. A clip LED will light when a signal level of 5db before clipping occurs.
The 351 may be used in a variety of applications, such as live sound, recording studios, instrument racks, effects loops, and virtually any conventional fixed installation environment. For more information, visit their web site at www.artroch.com, or write them at
