User manual RANE AD 22D

[. . . ] This stores the current Delay values into each channel's current Memory (A or B). The current Memory for each channel is indicated by the MEMORY LED lit when editing that channel. Both channel's current Delay values are stored with each press of the STORE button. To recall a stored Memory, press RECALL. [. . . ] e UP/DOWN buttons: Pressing these buttons increases/decreases the amount of Delay in the selected Channel(s). The two buttons just to the right of the LED display change Delay time in 1 millisecond steps. The far right buttons provide 10 microsecond steps. For distance displays (feet and meters), these buttons are FINE and COARSE adjustments, since Delay increments are always in 1 msec and 10 µsec steps, regardless of the DISPLAY MODE. r TEMPERATURE setting: Holding down DISPLAY MODE while pressing the up/down buttons displays the current temperature setting in degrees Celsius for the 1 msec/COARSE buttons and degrees Fahrenheit for the 10 µsec/FINE buttons. Further up/down presses change the temperature setting. No matter which unit (°C or °F), adjustments are always in 1°C steps (or 1. 8°F).

RANE CORP. 650mA CLASS 2 EQUIPMENT CH1 CH2 GND ACN 001 345 482 CH 2 OUT CH 2 IN CH 1 OUT CH 1 IN 1 2 3 4 5 1 Chassis ground point: A #6-32 screw and toothed washer is provided for chassis ground. Since the AD 22d does not get chassis ground through the AC cord, this point is provided in case your system does not have another earth ground such as the rack rails. 2 POWER input connector: No this is not where Commissioner Gordon plugs in his Bat-phone, in fact it is not a telephone jack at all. The AD 22d uses an 18 volt AC center-tapped transformer only. Use only a model RS 1 or other remote AC power supply approved by Rane. The AD 22d is supplied with a remote power supply suitable for connection to this jack. Consult the factory for replacement or substitution. 3 REMOTE RECALL terminals: Wiring external configuration switches to these terminals allows remote recall of the two nonvolatile memories for each Channel. When the switch closes, Memory B for the given Channel is recalled. When the switch opens, Memory A is recalled. These terminals use CMOS (+5 volt) logic levels and sink only 0. 5 mA (max. ) each. 4 Recessed lockout switch: Enables the Front Panel Lockout mode. In this mode all front panel controls, with the exception of the CHAN and DISPLAY MODE buttons, are disabled. The Channel button remains active so the user may view the current Delay values without risk of changing them, and the display mode button allows display of Delay values in milliseconds, feet or meters. [. . . ] You can only edit the current Delay values in each channel, which can then be stored in either of two nonvolatile Memories, A and B. SENSITIVITY SETUP The first step is to apply signal, and adjust the SENSITIVITY controls. If you know the nominal level, adjust the control so its indicator points to that level. Otherwise, set the SENSITIVITY control so high signal peaks just illuminate the CLIP indicator, then back off a little. [. . . ]
