Manual-3
REAR PANEL DESCRIPTION
1. 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 this 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 CORPORATION. Using any other type of supply may damage the unit and void
the warranty.
2. Ground LIFT switch. This switch provides the ability to separate chassis ground and signal ground. Normally, this switch
should be in the LIFT position. In some circumstances, moving this switch eliminates hum problems. Always turn your
amplifier levels down before changing this switch and bring them up slowly.
3. Chassis ground. A 6-32 screw used for chassis grounding purposes. See CHASSIS GROUNDING below.
4. LEFT, CENTER & RIGHT OUTPUT connectors. Active unbalanced design. Use only high-grade RCA cables for
connection to the power amplifier inputs.
5. LEFT, CENTER & RIGHT INPUT connectors. Active unbalanced design. Use only high-grade RCA cables for connec-
tion to the surround sound decoder outputs.
6. SUBWOOFER OUTPUT connector. Active unbalanced design. Use only high-grade RCA cables for connection to the
subwoofer power amplifier input.
7. SUBWOOFER ENGAGE switches. Pressing both of these switches to the in position and illuminating the red LEDs
engages the crossovers and routes the low frequencies to the SUBWOOFER OUTPUTS.
8. SUB SOURCE switches. These switches determine if the SUBWOOFER OUTPUT for each Channel gets its input from the
Left, Right, or a summed Left/Right signal. Set these to LEFT and RIGHT for stereo subwoofers, and L&R when using a
mono subwoofer.
9. CROSSOVER FREQUENCY switches. One each for Left and Right Channels. This sets the built-in 24 dB per octave
crossover to only allow frequencies below 80 Hz or 125 Hz to the subwoofer(s) in each Channel, thereby improving
subwoofer efficiency. If the subwoofer has a crossover frequency ajustment, set it to its highest value when using the SSE
35. Refer to the OPERATING INSTRUCTIONS on page Manual-6.
CHASSIS GROUNDING
If after hooking up your system it exhibits excessive hum or buzzing, there is an incompatibility in the grounding
configuration between units somewhere.
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.
Please refer to RaneNote 110 “Sound System Incterconnection” (supplied in this manual) for further information on
system grounding.
