User manual RANE AVA 22

[. . . ] STORING DELAY--Press the STORE button (the STORE LED turns off). This stores the current Delay values into each Channel's current Memory (A or B). The current Memory is indicated by the lit MEMORY LED for each Channel. Both Channel's current Delay values are stored with each press of the STORE button. [. . . ] See RaneNote 110, "Sound System Interconnection" located elsewhere in this manual. POWER connector: No, this is not where commissioner Gordon plugs in his Bat-phone, in fact it is not a telephone jack at all. The AVA 22 uses an 18 volt AC center-tapped transformer only. Use only a model RS 1, RAP 10 or other remote AC power supply approved by Rane. The AVA 22 is supplied with a remote power supply suitable for connection to this jack. Consult the factory for replacement or substitution. Chassis ground point: A #6-32 screw and toothed washer is provided for chassis ground. Since the AVA 22 does not get chassis ground through the AC cord, this point is provided if your system does not have another earth ground such as the rack rails. IMPORTANT NOTES FCC & VDE NOTICE This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules, and similar requirements found in European specifications EMCD 89/336/EEC. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy, and if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at their own expense. CHASSIS GROUNDING If your system exhibits excessive hum or buzzing, there is an incompatibility in the grounding configuration between units. Try combinations of lifting grounds on units supplied with ground lift switches (or links). Verify all chassis are tied to a good earth ground. Units with outboard power supplies do NOT ground the chassis through the line cord. Make sure these units are solidly grounded by tying the Chassis Ground Point to known earth ground. Use a star washer to guarantee proper contact. (See the RaneNote "Sound System Interconnection" for more. ) Manual-3 AVA 22 CONNECTION When connecting the AVA 22 to other components in your system for the first time, leave the power supply for last. This gives you a chance to make mistakes and correct them before any damage is done to your fragile speakers, headphones, ears, or brains. The AVA 22 passes audio while it is unpowered by virtue of its fail safe bypass relays (when the AVA 22 functions as a wire). Turn the system volume down before plugging in the AVA 22's power. INPUTS The AVA 22's Inputs are electronically balanced. [. . . ] ADJUSTING CURRENT DELAY VALUE One Channel at a time: With the LINK LED off, press the up/down buttons for the Channel you want to adjust until the desired Delay value is reached. To avoid audible anomalies, the AVA 22 bypasses the audio signal any time the Delay value is changed. Both Channels simultaneously: With the LINK LED on, changing either Delay value changes the other Channel's Delay value by the same relative amount. (The Delay values are linked. ) BYPASS, RECALL and broadcast MODE are also linked together in LINK mode. [. . . ]
