ART Introduces Model 355 Dual Channel, 31 Band Equalizer
October 24, 1997Rochester. New York - Applied Research and Technology. Inc., the Rochester. New York-based
manufacturer of analog and digital signal processing equipment, is introducing the Model 355 Dual
Channel 31 Band Equalizer.
The Model 355 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, adjustable high pass filter, adjustable low pass filter, variable input level control,
clip level indicators, ground lift switch, along with an internal power supply and a selectable line
voltage switch. A range control switch is provided which allows 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 250Hz. 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 sibilance from a signal. Its range is adjustable
from 3kHz to 40kHz.
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
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 rugged, all-steel constructed chassis of the Model 355 occupies 2U rack space, and is intended
for installation in standard 19" equipment racks. For more information, visit their web site at www.artroch.com. |
