Rane AD 22D - Manual (Page 5)

Manual-
REAR PANEL DESCRIPTION
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.
See the CHASSIS GROUNDING note below.
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 replace-
ment or substitution.
3 REMOTE RECALL terminals: Wiring external configuration switches to these terminals allows remote recall of the two non-
volatile 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.
Press RECALL while in LOCKOUT to temporarily display, but not Recall, the value of the other stored Memory for the indi-
cated 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. These limits are designed to provide reasonable
protection against harmful interference when the equipment is
operated in a residential installation. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harm-
ful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installa-
tion. If this equipment does cause harmful interference to radio
or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following:
1. Re-orient or relocate the receiving antenna.
2. Increase the separation between the equipment and the
receiver.
3. Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
4. Consult the dealer or an experienced radio/TV technician.
CANADIAN EMC NOTICE
This Class B digital apparatus meets all requirements of the
Canadian Interference-Causing Equipment Regulations.
Cet Appariel numerique de la classe B respecte toutes les
exigences du Reglement sur le material broilleur du Canada.
CHASSIS GROUNDING
If after hooking up your system it exhibits excessive hum or
buzzing, there is an incompatibility in the grounding configura-
tion between units. Here are some things to try:
1. Try combinations of lifting grounds on units supplied with
ground lift switches (or links).
2. Verify all chassis are tied to a good earth ground.
3. Some 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.
