The dbx® 12 Series were designed to meet the
needs of the most demanding sound reinforcement
environments, while offering the simplicity of
straightforward controls and providing years of maintenance-free operation in any application. The magnetically-isolated transformer, electronically balanced inputs and servo balanced outputs, RF-filtered inputs and outputs, and power-off hard-wire relay bypass with 2 second power up delay were steps our engineers took to ensure compatibility for all installations.
Only the best components were utilized, yielding
a 10Hz to 50kHz frequency response, greater
than 90dB SNR (ref +4dBu), less than 0.005% THD
+Noise (1kHz at +4dBu), and interchannel crosstalk
of less than -80dB from 20Hz to 20kHz. All this
attention to detail is contained in a 2U steel/aluminum chassis.
The 1231 provides standard features like dual-channels, 31 1/3 octave bands,
ISO frequency centers, +/- 12 dB input gain range, and switchable 40Hz/18 dB per
octave low-cut filters
The 12 Series EQs also offer: 45 mm faders; selectable +/-6dB or +/-15dB
boost/cut range for precise gain adjustments; XLR, barrier strip, and 1/4' TRS connectors
for installation ease; balanced inputs and outputs for quiet operation; and
chassis/signal ground lift capabilities for quick hum isolation.
