User manual RANE AD 22D

[. . . ] Both channel's current Delay values are stored with each press of the STORE button. Each press of this button alternately recalls stored Memories (A then B then A. . . ) for the selected channel only. A quick way to recall Memories into both channels simultaneously, is to store both channel's values into the same Memory. With both channels selected (both CHAN LEDs on), press RECALL to restore both channel's Memories at the same time. [. . . ] q DISPLAY MODE button & LEDs: This button changes the units of displayed Delay values from Milliseconds to Feet to Meters. The LEDs indicate the current Display Mode: MILLISECONDS, FEET or METERS. w 5-digit LED display: indicates the current Delay value for the selected channel. When both channels are selected, the smaller of the two channel's current Delay values is displayed. This display also shows the current temperature setting when holding down the DISPLAY MODE button and pressing one of the up/down buttons. 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. 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. 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. 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. 3 REMOTE RECALL terminals: Wiring external configuration switches to these terminals allows remote recall of the two nonvolatile memories for each Channel. These terminals use CMOS (+5 volt) logic levels and sink only 0. 5 mA (max. ) each. 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. Press RECALL while in LOCKOUT to temporarily display, but not Recall, the value of the other stored Memory for the indicated channel. (See OPERATING INSTRUCTIONS for optional Bypass lockout mode, and MEMORY BUTTONS on previous page. ) 5 INPUT/OUTPUT connectors: Nothing new here, the AD 22d uses balanced XLRs, with pin 2 "hot" per AES standards. FCC NOTICE This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. [. . . ] This is useful for initial troubleshooting and allows verification of signal flow. 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. [. . . ]
