REAR PANEL DESCRIPTION
1
XLR INPUT/OUTPUTS:
Nothing new here, balanced Ins and Outs. If you can tolerate unbalanced characteristics (like hum),
you can also wire the AVA 22d in an unbalanced configuration. See the RaneNote, “Sound System Interconnection” located else-
where in this manual.
2
Front Panel Lockout switch:
Enables the Front Panel Lockout mode. In this mode all front panel controls, with the exception of
the RECALL buttons, are disabled. Press a RECALL button while in Lockout to temporarily display, but
not
Recall, the value of
the other stored Memory for the given channel. (See Operating Instructions for optional Bypass Lockout mode.)
3
REMOTE RECALL & BYPASS terminals:
Wiring external configuration switches to these terminals allows remote stereo
bypassing or stereo memory recalling of the two nonvolatile memories. These terminals use CMOS (+5 volt) logic levels and source
only 0.5 mA (max) each.
4
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 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 AVA 22d is supplied with an RS 1 remote power supply. Consult the factory for replacement.
5
Chassis ground point:
A #6-32 screw and toothed washer is provided for chassis ground. Since the AVA 22d 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.
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.
