Product Highlights:
The 351 single channel, 31 band 1/3 octave graphic equalizer features constant Q circuitry, with a 3% center frequency accuracy. The sliders are 20mm center detent with a selectable boost/cut range, and the unit provides active balanced and unbalanced input and output connections, adjustable high pass and low pass filters, variable input level control, clip level indicators, ground lift switch, internal power supply with selectable line voltage switch.
The 351 has a bypass switch with LED indicator, is housed in a rugged, all-steel constructed chassis which 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. Both the XLR and 1/4″ connectors may be used in an unbalanced configuration. The RCA jacks are unbalanced. The unit 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.
The 351 may be used in a variety of applications such as live sound, recording studios, instrument racks, as well as any conventional fixed installation environment.
