User manual RANE SSE 35

[. . . ] See the included Rane Note 132 for stereo or mono subwoofer tips. See the Operating Instructions on the back page for basic alignment info. Install the supplied security cover after completing all settings. Be sure the POWER light fits snugly into the hole in the security cover. [. . . ] 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. 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. 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. Manual-3 SSE 35 CONNECTION When first connecting the SSE 35, leave the power supply for last. This gives you a chance to correct mistakes before damaging fragile speakers, ears and nerves. INPUTS Inputs are unbalanced and fitted with standard RCA phono jacks. Only use high-quality RCA cables for hook-up. SIGNAL LEVELS The SSE 35 is designed for Home Theater Audio reference levels, and provides a minimum headroom of 26 dB above reference, making it virtually unclippable. With all slide controls located in their 0 dB detented positions, the SSE 35 operates with unity gain from input to output. No additional level controls are necessary. Use the SSE 35 only for specific equalization, not as a gain control. The average of all sliders should be 0 dB or less--volume should be relatively the same when activating the BYPASS switch. Lowering the mountains makes less filling in the valleys. ALIGNMENT (See Operating Instructions). Once the room is aligned, purists will install the security cover and never adjust again until the room is re-arranged. Some of you will be impressed with all those little sliders and want to play. The SSE 35 comes ready for 19" rack mounting. The rack ears may be moved forward to allow the security cover to be mounted flush with the rack face. [. . . ] If more is required, use architectural and mechanical means: change, add, remove, or relocate acoustically sensitive items (speakers, drapes, carpets, mirrors, etc. ) as required. USING THE BYPASS SWITCH The SSE 35 provides an equalizer BYPASS switch & indicator as a useful tool for optimizing settings. Use the BYPASS switch for making quick "A-B" comparisons, that is, comparing "A", equalized (BYPASS out, LED off), versus "B", unequalized (BYPASS in, LED on). To do this freely, without danger of system damage, you must first pay attention to how much equalization is being used. [. . . ]
