Dual 15-band, 2/3-octave Constant Q frequency bands
The 1215 offers allows true 2/3-octave bandwidth control at all slider positions.
Switchable boost/cut ranges of ±6 or ±15dB
The 1215 features a boost/cut switch that allows you to select which of the two boost/cut ranges the equalizer will use, either ±6 dB or ±15 dB. The red LED lights when the ±15dB range is selected, and the yellow LED lights when the ±6dB range is selected. Note that the BOOST/CUT switch is slightly recessed. This is to prevent accidental activation of the switch, possibly causing damage to other sound system components.
Bypass the EQ with a simple press of the 1215's bypass switch that is conveniently located on the front panel.
±12 dB input gain range
The 1215 is capable of -12 dB to +12 dB of gain.
4-segment LED ladders for monitoring output levels
The four Output Level LEDs indicate output level of the equalizer. The red LED is 3dB below clipping and is marked as +18dBu. It monitors the level at the output of the equalizer after all other processing.
XLR and TRS Inputs and Outputs
The 1215 has balanced inputs and outputs that can be used with any balanced or unbalanced line-level device.
Frequency Response of <10Hz to >50kHz
The 1215 is able to easily respond and adjust for a speaker's frequency response based on its amazing 10 Hz to 50 kHz frequency response range.
18dB/octave 40Hz Bessel Low-Cut filter
The 12 Series feature a 40Hz 18dB/octave Bessel high-pass filter used to reduce rumble or stage vibrations. The LOW-CUT switch inserts or removes the 18dB/octave 40Hz Bessel low-cut filter from the signal path. When the LOW-CUT switch is pushed in, the LOW-CUT filter is IN the audio path.
Visionary design, revolutionary engineering
The dbx® 12 Series were designed to meet the needs of the most demanding sound reinforcement environments, while offering the simplicity of straightforward controls. The 1215 provides standard features like dual channels, 15 2/3 octave bands, ISO frequency centers, +/-12 dB input gain range, and switchable 40Hz/18 dB per octave low-cut filters, but also includes other thoughtful features. These include 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. The visionary design of the dbx 12 Series makes your job easier. The dbx 12 Series Equalizers were precision engineered to provide years of maintenance-free operation in any application. The magnetically isolated transformer, electronically balanced/unbalanced inputs and servo balanced/unbalanced 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.
