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. 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" 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 351 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.
