User manual RANE DEQ 60

[. . . ] The A and B switches are like memories or control assigns. Normal stereo use would set the top row A (Left), and the bottom row to B (Right). But if you are running in stereo, and both sides use the same EQ curve, you can set both switches to A. Now the top EQ curve controls both left and right channels. [. . . ] 2) Compensate for changes in signal level due to filter boost/cut settings by adjusting the OUTPUT signal level to 0 dBu. The operation of the OUTPUT LEVEL control is reversed. Pushing the control down increases the gain. This allows the user to easily adjust sensitivity without affecting the output signal level. Simply grasp both input and output controls and move together. The ranges of both controls is ±12 dB with a resolution of 256 steps. 5 BYPASS switches have two possible modes of operation. 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. 7 PERFECT-QTM: What you see is what you get. PROPORTional-Q: Classic smooth response. Most users will prefer the PERFECT-Q position. Some users may prefer the PROPORT-Q setting. See Graphic EQ Controls on page Manual-4. 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. Peak-dBu is held and displayed for 1. 5 seconds. 0 When the POWER indicator is on, it indicates that power is turned on. [. . . ] Inside the DEQ 60 is a universal internal switching power supply that accepts 100 to 240 VAC at 50 to 60 Hz, allowing it to work in most countries.
