[. . . ] Near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool, etc). Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through openings. POWER SOURCES: The appliance should be connected to a power supply only of the type described in the operating instructions or as marked on the appliance. GROUNDING OR POLARIZATION: Precautions should be taken so that the grounding or polarization means of an appliance is not defeated. [. . . ] Its function is to monitor the input signal and intelligently predict the amount of gain reduction needed to keep the output signal below the ceiling set by the Instantaneous Transient ClampTM. Note, since the PeakStopPlusTM limiter is a fail-safe limiter it must come after the OUTPUT GAIN control. If the OUTPUT GAIN is set too high as compared to the PeakStopPlusTM LEVEL control, continuous limiting can occur. While PeakStopPlusTM is typically used as a protective function, creative effects can be achieved by intentionally driving the signal into heavy PeakStopPlusTM limiting. Great care has gone into the design of the PeakStopPlusTM limiter to keep it acoustically transparent. Appropriate use of it can protect your gear while keeping the signal free of artifacts. PeakStopPlusTM Threshold (+) LED Indicator - This LED illuminates when the output signal exceeds the level set by the PeakStopPlusTM LEVEL control indicating that PeakStopPlusTM limiting is occurring. The signal with the thin line weight represents an unaltered input signal. as you can see , peaks of the input signal exceed the clamping level. The peaks of the input signal which exceeded the clamping level are not allowed to exceed this level at the output. This instantaneous protective action is invaluable for driver protection in speaker systems and for digital recording where it is desirable to record as "hot" as possible, while still avoiding the disastrous result of running out of headroom. Following this clamping action, Intelligent Predictive LimitingTM takes over, typically within 5ms, as long as the input signal continues to exceed the PeakStopPlusTM threshold. This program limiter quickly attenuates the input signal to a level safely below the clamping level, typically 2 dB lower than the clamping level. The PeakStopPlusTM level control is calibrated to this lower level, so if an absolute ceiling is required, set the level 2 to 3 dB below the front panel setting. As implied by the name, the attack and release times of the Instantaneous Transient ClampTM are zero, while the Intelligent Predictive LimitingTM attack and release times are program-dependent. That is, for larger excursions over the threshold, the attack time speeds up, and for smaller excursions over the threshold, the attack time slows down. Similarly, for large excursions over the threshold which cause more PeakStopPlusTM gain reduction, the release time increases and is roughly proportional to the amount of gain reduction that occurred. The AC receptacle includes an integral pull-out fuse drawer which contains two fuses: the active fuse and a spare fuse. The 1066 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. audio Outputs - Each channel features both XLR and 1/4" TRS servo-balanced outputs. operating Level Switch - This switch selects between a -10 dBV and +4 dBu nominal operating level. [. . . ] Assuming the tom-tom is a lower frequency instrument and can be better tolerated by the tape, it has less need for compression. The equalization in the detector circuit means that the compressor is not triggered as readily by a loud tom-tom beat as by an equally loud cymbal crash. The converse of the above EQ technique can be used: dipping the equalizer bands causes any sound with dominant energy in the affected register to pull the level up because the 1066 will detect a need for less compression. Frequency-weighted compression for Multi-way Speaker Systems If a single compressor is to be used with a multi-way speaker system (i. [. . . ]
