User manual RANE DEQ 60L

[. . . ] Since there is no interaction between filters, the multiple adjustments through all the bands just to get the analyzer to read flat is a thing of the past. If you want to compare the sound of your old (non-Rane) EQ to this one, and you are used to the way the slider bands interact, then use PROPORTIONAL-Q mode. Activating the CUT-ONLY switch puts both equalizer channels in the high resolution CUT 0 to -12 dB (gray number scale). To prevent unwanted sudden volume shifts when switched, the outputs mute for a moment, then slowly increases in volume. [. . . ] This allows the user to easily adjust sensitivity without affecting the output signal level. The ranges of both controls is ±12 dB with a resolution of 256 steps. If the rear panel switch is set to BYPASS ALL, all filters and level controls are bypassed. If the rear panel switch is set to BYPASS FILTERS, only the filters are bypassed. Automatic relay bypass hardwires Inputs to Outputs in the event of a power failure. 6 A / B switches determine which set of controls is used by the A-channel or B-channel. Controls affected by the A / B switch are EQ, TONE, CUT FILTERS, LEVEL, Q switches and ±12 / ±6 dB switches. 8 ±12 / ±6 dB switch changes the boost / cut of the Graphic EQ (1) for each channel. Use the ±6 dB unless you really need ±12 dB, the resolution is better. 9 Input and Output Meters are peak responding and indicate the signal level in dBu. 0 When the POWER indicator is on, it indicates that power is turned on. q CUT-ONLY mode switch: when pressed in, as shown by the LED, sets the range of the EQ sliders 0 to -12 dB (gray number scale). When the switch is actuated, the output audio is muted and slowly increased to prevent volume surprises. Manual-2 REAR PANEL DESCRIPTION OUTPUT B OUTPUT A INPUT B INPUT A WIRING DEQ 60L MADE IN U. S.

Choose between the XLR, the ¼" TRS, or the Euroblock Input jack--use only one--they do not sum. standard for balanced pin configurations: Pin 1 is chassis ground (neutral), pin 2 is hot (positive), and pin 3 is signal return (negative). Avoid the temptation to use unbalanced tip-sleeve ¼" TS plugs, but if you must, keep them short as possible, 10 feet (3 meters) maximum. The Euroblocks normally connect the cable shield to the ground terminal. [. . . ] The lack of band interaction guarantees slider settings accurately indicate frequency response.

Control Surface All graphics are screened on the reverse side of a durable Lexan surface. Universal Switching Power Supply The DEQ 60L operates on any AC mains from 100 VAC to 240 VAC, 50 Hz or 60 Hz. The line cord attaches to a standard IEC appliance inlet, shipped with each unit.
