Drive Level switch

Note that since the PeakPlusª Limiter is a fail-safe Limiter it must come after the Output Gain con- trol. If the Output Gain is set too high as compared to the PeakPlusª Level control, continuous lim- iting can occur. While PeakPlusª is typically used as a protective function, creative effects can be achieved by intentionally driving the signal into heavy PeakPlusª limiting.

Great care has gone into the design of the PeakPlusª Limiter to keep it acoustically transparent. Appropriate use of it can protect your gear while keeping the signal free of artifacts. Peak Plusª also serves to prevent digital overload when used in conjunction with the dbx Type IVª Conversion System option.

This configures the meter to show the signal level at the input to the vacuum tube. Note that high gain settings can result in excessive movement of the meter as the needle contacts the endpin. In this sit- uation itÕs best to briefly check the drive level and then switch to one of the other meter modes.

GAIN REDUCTION switch

This configures the meter to show the amount of gain reduction due to compression. The lower mark- ings on the meter show increasing gain reduction from right (0 dB) to left (-30dB). Note that when configured to the Gain Reduction setting, the meter swings from the fully right position and not the 0 dB position indicated on the top line of the meter.

OUTPUT LEVEL switch

This configures the meter to show the output signal level. This works in conjunction with the output level assignment switch on the back of the 566. When the rear switch is set to +4 dBu, a meter read- ing of 0 VU corresponds to +4 dBu output. When the rear switch is set to -10 dBV, a meter reading of 0 VU corresponds to -10 dBV output.

LINK Switch:

This switch changes the 566 from two independent compressors into a stereo compressor, and also links the two independent limiters into a stereo limiter. In stereo link mode a peak in either side of the compressor will activate both compressor channels equally. This helps to preserve stereo imag- ing. Channel One is the master and Channel Two is the slave except for the following controls: Sidechain Enable, Sidechain Monitor, Contour, and Bypass switches. Additionally, Channel Two's Compressor Threshold LEDs and PeakPlusª Limiter LED will be disabled, while both channels' Gain Reduction metering will identically indicate the amount of gain reduction occurring. It is important to note that while Channel One is the master as far as the controls go, both channels have equal precedence as far as signal processing is concerned. The dbx 566 uses True RMS Power Summingª, an extremely accurate and musical way to combine detector outputs in a stereo situa- tion. The Link Switch will light to indicate that the 566 is in the stereo link mode.

566 specifications
