Rane AVA 22 1995 version - Manual (Page 3)

Manual-3
REAR PANEL DESCRIPTION
ቢ REMOTE BYPASS/RECALL 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 sink only 3mA (max) each.
ባ 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.)
ቤ XLR INPUT/OUTPUTS:. Nothing new here, balanced Ins and Outs. If you desire unbalanced characteristics (like hum),
you can also wire the AVA 22 in an unbalanced configuration. See RaneNote 110, “Sound System Interconnection” located
elsewhere in this manual.
ብ 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.
ቦ 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. 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. 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
