REAR PANEL DESCRIPTION
햲
Remote POWER supply input.
The unit is supplied from the factory with a Model RS 1 Remote Power Supply suitable for
connection to this input jack. The power requirements of the unit call for an 18 volt AC center-tapped transformer only.
This
is not a telephone jack.
Never use a power supply other than the one supplied, or a replacement approved by Rane Corpo-
ration.
Using any other type of supply may damage the unit and void the warranty.
햳
Chassis ground.
A #6-32 screw is used for chassis grounding purposes. See CHASSIS GROUNDING below.
햴
RCA OUTPUT connectors.
Active unbalanced design. Use high-grade RCA cables or the DB-25 to connect to the power
amplifier inputs. You may use both simultaneously when required to feed different amplifiers.
햵
RCA INPUT connectors
. Active unbalanced design. Use either high-grade RCA cables
or
the DB-25 for interconnect to
the controller outputs.
Do not use both the RCA and the DB-25 input connectors—the Inputs do not sum.
햶
DB-25 connectors.
Wired per the Home THX Interconnection Standard. Refer to the silkscreened legend on the rear for pin
identification.
Use only THX approved DB-25 Interconnection cables.
Other DB-25 cables may not function properly.
CHASSIS GROUNDING
If your system exhibits excessive hum or buzzing, there is an incompatibility in the grounding configuration between
units somewhere. Your mission, should you accept it, is to discover how your particular system wants to be grounded.
Here are some things to try:
1. Try combinations of lifting grounds on units that are supplied with ground lift switches or links.
2. If your equipment is in a rack, verify that all chassis are tied to a good earth ground, either through the line cord
grounding pin or the rack screws to another grounded chassis.
3. Units with outboard power supplies do
not
ground the chassis through the line cord. Make sure that these units are
grounded either to another chassis which is earth grounded, or directly to the grounding screw on an AC outlet cover by
means of a wire connected to a screw on the chassis with a star washer to guarantee proper contact.
4. Sometimes cable TV systems can introduce another ground loop in combination with grounded amplifiers. Using an
isolation transformer between grounded audio components may solve the problem. See Rane models BB 44x or BB 22.
