DOD SR231QX 2 Channel 31-Band Graphic Equalizer w/ Balanced XLR & 1/4 Connectors

The unit provides active balanced input and output connections, high pass filters, bypass switches for each channel, and an internal power supply. Electronic switching of the bypass minimizes switching transients, such as loud pops or clicks when the switch is depressed. The SR231QX's fully shielded internal transformer provides extremely quiet operation, and multiple input and output configurations are provided for ease of use. The XLR and 1/4" TRS connectors use active balanced, low-noise circuitry, while the 1/4" connectors will also accept an unbalanced plug.


The input level control covers a wide range, thus allowing the unit to work with a variety of signal levels. Output levels can be monitored on each channel by four-LED peak-reading bar graphs. The SR231QX may be used in a variety of applications such as live sound, recording studios, instrument racks, as well as any conventional fixed installation environment.
