ART's 341 Dual-Channel, 15-band, 2/3-octave graphic equalizer features: constant Q circuitry with a 3% center frequency accuracy, 20mm center detent sliders, selectable boost/cut range of 6dB or 12dB, active balanced and unbalanced input and output connections, 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. Each channel has its own 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. XLR connections are: Pin 1 = ground, Pin 2 = Hot (+), and Pin 3 = Cold (-). The 1/4 inch TRS connections are: Tip = Hot (+), Ring =Cold (-), and Sleeve = ground. Both the XLR and 1/4" connectors may be used in an unbalanced configuration. The RCA jacks are unbalanced. The 341 is designed to work with a variety of signal levels. 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 341 may be used in a variety of applications such as live sound, recording studios, instrument racks as well as any conventional fixed installation environment. Use the 341 equalizer wherever modification of the frequency contour of a sound is needed. The 341 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 341 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 the 341 into the effects loop of an instrument amplifier or between a preamp and power amp to have precise control over the complete sound.
The 341 Dual 15 Band EQ has the features and performance you need for any of your audio applications requiring equalization.
