In line with the company's policy of continual improvement, specifications and function may be subject to change without notice. This Operator Manual was correct at the time of writing. [. . . ] Defines a waiting period before the gate starts to close once the signal has been detected as having fallen below threshold. Adjusts the time its takes for the gate to close after the program material falls back below threshold and the hold time has elapsed. Adds an overshoot characteristic when the gate is opening, which accentuates the transient. Reverses the operation of the gate so that it closes when signals go over threshold and opens when they go below threshold. When the DUCK switch is on, the ACCENT control and the ACC LED are disabled. On/off status indicator for the DUCK pushbutton. Adjusts the amount of gain reduction that is applied to signals that are below threshold. For details, see "Metering" on page 15. Adjusts the operating point (threshold) of the gate. Disconnects the gate from the main signal path. On/off status indicator for the BYPASS pushbutton. 3 Control knob RELEASE 4 5 Control knob Pushbutton ACCENT DUCK 6 7 8 9 10 11 LED (orange) Control knob LED Control knob Pushbutton LED (red) Not applicable RANGE Various THRESHOLD BYPASS Not applicable 14 DN530 Operator Manual Gate section Metering The key to successful DN530 operation is to know when signals are above or below threshold. This is especially true if the accent feature is used with low range settings or with no gating action at all. This style of metering provides an intuitive moving LED indication that ramps up and down as the signal level moves around the threshold point. The metering comprises the following LEDs: Label CLIP ACC THR HLD REL SHUT Colour Red Blue Green Yellow Orange Red Function Clip LED for showing when the signal is being clipped. Accent LED for showing when the ACCENT control is applying positive signal gain. Over threshold LED for showing when the signal has gone over threshold. Hold LED for showing when the HOLD control is delaying gate closure. Release LED for showing when the RELEASE control is delaying gate closure. Shut LED for showing when the gate is closed to the level set by the RANGE control. DN530 Operator Manual 15 Chapter 4: Front Panel Sidechain section The signals that feed the gate's sidechain are called the "sidechain". A band pass filter is provided that acts on the sidechain signals. The sidechain section for each channel can be broadly divided into two areas: filter and solo. The filter section comprises the FREQUENCY control knob and the FILTER and EXT pushbuttons, and the solo section consists of the SOLO pushbutton. 7 6 5 4 Item 1 2 Type LED (yellow) Pushbutton Label Not applicable EXT Function 1 2 3 On/off status indicator for the EXT pushbutton. [. . . ] Check the controls for freedom of operation. Check the functionality of all controls, that is, control knobs, pushbuttons and LEDs. You can carry out a visual check of all illuminated items (LEDs etc. ) by switching the unit off and then on again, as they should all illuminate during power up. Check the functionality of the equipment. · Cleaning Switch off the unit and electrically isolate it from the mains before cleaning. [. . . ]
