User manual RANE VP 12

[. . . ] While doing this adjust the INPUT GAIN control so that the loudest sounds will occasionally illuminate the OL LED. If you are using the LINE IN, adjust the output level of the previous device to occasionally illuminate the OL LED of the VP 12 when the loudest signal you expect to hear is present. Adjust the VP 12 OUTPUT LEVEL controls to match the device you are driving. Now taking one processing section at a time, release its BYPASS switch and adjust the processing controls. [. . . ] Since the VP 12 is powered from a remote AC supply which does not carry chassis ground through to the grounding pin of the AC line cord, this screw has been provided in case your system does not have another earth grounding means such as through rack rails, etc. The VP 12 is supplied from the factory with a Model RS 1 Remote Power Supply suitable for connection to this input jack. The power requirements of the VP 12 call for an 18-24 volt AC center-tapped transformer only. Never use a power supply with your VP 12 other than the one supplied or an exact replacement obtained from or approved by Rane Corporation. Using any other type of supply may damage the unit and void the warranty. Two years parts and labor is worth safeguarding, don't you think?A three year warranty is available by completing and mailing in the warranty card, before something goes wrong. Are fully balanced outputs, controlled by the front panel OUTPUT LEVEL. When driving high impedance loads, both screw terminals and XLR jacks can be used at the same time. Configured from the factory with all functions active, in the same order as the front panel. This also allows a function block, such as the EQ, to patch into and out of the VP 12 to an external processor or mixing channel. Do not use both screw terminals and the ¼" TRS jack simultaneously. When this switch is in, 48 VDC is fed to the MIC IN jack and the LED is lit.

This gives you a chance to make mistakes and correct them before any damage is done to your fragile speakers and nerves. The MIC input of the VP 12 is balanced and accepts a standard XLR cable from the MIC of your choice. As with all Rane products and AES standards, pin 2 is used for "hot" or "+" polarity, pin 3 is "return" or "­" and pin 1 is chassis ground. If you are not using PHANTOM POWER you may use either pin 1 or case for shield ground on the VP 12 input. However, if you are using PHANTOM POWER, pin 1 must be shield grounded to provide a complete electrical circuit. The LINE/EXPAND input of the VP 12 is also balanced, as a TRS jack or screw terminals. The tip is "+", the ring is "­", and the sleeve is chassis ground. Unbalanced wiring such as a standard ¼" TS plug may also work, but with possible compromises in level adjustments. As expected, pin 2 is "hot" or "+", pin 3 is "return" or "­" and pin 1 is chassis ground. [. . . ] For simple tone contours all you need to do is adjust the BW control to a larger number like 2. 0, and now you have affected a broad range of frequencies. BW is measured in octaves, and each doubling or halving of a frequency equals one octave. Adjusting the FREQUENCY range switch selects multiples of the FREQUENCY control, allowing each band to cover the full 20 Hz to 20 kHz range while maintaining resolution of the FREQUENCY control. For a serious notch, for instance, adjust both sets of controls to the same settings. [. . . ]
