User manual DBX 164

[. . . ] GROUNDING OR POLARIZATION: Precautions should be taken so that the grounding or polarization means of an appliance is not defeated. POWER CORD PROTECTION: Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance. SERVICING: To reduce the risk of fire or electric shock, the user should not attempt to service the appliance beyond that described in the operating instructions. All other servicing should be referred to qualified service personnel. [. . . ] Note, when OverEasy® processing is selected, the ratio transitions smoothly from the linear to the compressed region. as the signal exceeds the threshold , the ratio approaches the ratio set by the COMPRESSOR RATIO control. Gain Reduction Meter - This 12 stage meter shows the amount of gain reduction due to compression, expansion/gating, or Intelligent Predictive LimitingTM, displaying gain reduction from 0 to 30 dB. Attack Control - The ATTACK control sets the amount of time it takes the 164 to begin compressing a signal once the detector has sensed a signal above threshold. The ATTACK range is from 3 dB/msec (for a tighter and more noticeable compression effect with very little overshoot) to . 04 dB/msec (for more delayed , gradual compression). A very fast ATTACK setting will cause the 164 to act like a peak limiter Release Control - The RELEASE control sets how fast the compression circuit returns the input to its original level. The RELEASE rate is from 250 dB/sec (where compression follows the envelope of the program material very tightly) to 5 dB/sec (for very smooth compression). Auto Switch - This switch overrides both the ATTACK and RELEASE controls and enables preset program-dependent attack and release times. These times are derived from the input signal and continuously change to match its dynamics. The switch lights indicating the attack and release times are being automatically adjusted in a program-dependent fashion. replace the fuse with the same type and rating only. AC Power Switch - Use this switch to turn the unit on and off. The 164 may also be turned on and off via a master equipment power switch. audio Inputs - Each channel features both XLR and 1/4" TRS electronically balanced inputs. Inputs may be used in a balanced or unbalanced configuration. audio Outputs - Each channel features both XLR and 1/4" TRS servo-balanced outputs. Outputs may be used in a balanced or unbalanced configuration. operating Level Switch - This switch selects between a -10 dBV and +4 dBu nominal operating level. When the switch is in the in position, a -10 dBV operating level is selected. When it is in the out position, +4 dBu is selected. sidechain Send Output - Each channel has a balanced 1/4" TRS SIDECHAIN SEND output. [. . . ] During the recording of cymbals and tom-toms, a compressor with an equalizer in the detector path can help prevent tape saturation. The equalizer can be adjusted for boost with a peak of about 5kHz, causing the cymbal to be compressed on a very loud crash, stopping tape saturation or digital overload at high frequencies, where there is less headroom. However, gentle tapping of a drumstick or brushing of the cymbal will not be held back. Assuming the tom-tom is a lower frequency instrument and can be better tolerated by the tape, it has less need for compression. [. . . ]
