Section 2 Getting Started dbx 266xs Section 2 - Getting Started 2.1 Rear Panel Connections IEC Power Cord Receptacle The dbx 266xs comes with a power supply that will accept voltages ranging from 100V-120V at frequencies from 50Hz-60Hz. An IEC cord is included. EU version accepts 220V-240V at frequencies from 50Hz-60Hz. WARNING: Be sure to verify your actual line voltage is the same as the voltage level printed below the AC power receptacle.
dbx 266xs Getting Started Section 2 2.2 Front Panel Connections STEREO COUPLE Switch This switch sets the 266xs for Stereo or Dual Mono operation. Press thee STEREO COUPLE switch in for stereo operation where Channel 1 becomes the host controller for both channels. All of Channel 2’s controls, switches, and LEDs will be disabled (except for the Channel 2 GAIN AIN REDUCTION meter), since Channel 2 is the linked channel. el.
Section 2 Getting Started dbx 266xs OVEREASY® Switch Depress this switch to select the OverEasy® compression characteristic. The amber THRESHOLD LED turns on when the signal is in the OverEasy region. When the switch is out, the 266xs operates as a hard-knee compressor, and the amber LED does not light. Compressor THRESHOLD Control and LEDs (BELOW/OVEREASY/ABOVE) Adjust this control to set the threshold of compression from - 40dB to +20dB.
dbx 266xs Getting Started Section 2 Compressor ATTACK and RELEASE Control The ATTACK control sets the amount of time it takes the 266xs to begin compressing a signal once the detector has sensed a signal above threshold. The ATTACK range is from FAST (for a tighter and more noticeable compression effect with very little overshoot) to SLOW (for more delayed, gradual compression). A very fast ATTACK setting will cause the 266xs to act like a peak limiter even though RMS detection circuitry is used.
Section 3 Making Connections dbx 266xs Expander/Gate RATIO Control This control sets the amount of attenuation applied to the input signal once it is below the threshold, from gentle downward expansion (appropriate for mixed program, vocals, etc.), to a hard gating effect (which can be useful for percussion). Fairly low RATIO (and higher Expander/Gate THRESHOLD) settings work best for downward expansion, whereas higher RATIO settings (clockwise towards MAX) work best for gating.
dbx 266xs Technical Support and Facts Section 4 Section 4 - Technical Support and Facts 4.1 Technical Support The 266xs is an all-solid-state product with components chosen for high performance and excellent reliability.
