OPERATORS MANUAL SSA 6 MULTICHANNEL AMPLIFIER QUICK START You gots your good habits, and you gots your bad habits. A good habit is to read at least this much of the manual. A bad habit is not to read any of this manual. Reading just this section can prevent grief worse than your worst nightmare. Grief that's hard to get rid of--harder than a bad habit. Be sure the amplifier is off before making any connections. Euroblock speaker connectors make connecting the amplifier easy. They are just like little snap-on terminal blocks that take up to 12 gauge wire. Gold plated RCA connectors take standard unbalanced sources. See Rane Note 110 for more information about other connectors. Keep your input cable lengths as short as possible. Speaker loads should be no less than four ohms per output. If you are running multiple speakers per Channel in series or parallel, check your final impedances. If you are running six separate Channels (unbridged), be sure all the BRIDGED switches on the rear panel are depressed. If you are running any Channels bridged, you are obviously a power user and we highly recommend you read further into the manual regarding this issue. With Input and Output connections completed, be sure all front panel LEVEL controls are all the way counterclockwise. Now flip the POWER switch and after hearing the relays click in after a second, notice that the READY lights come on. Slowly turn up each Channel's LEVEL control to the desired gain and if all is well you should hear something pleasant. If not, re-check connections, put on a better CD, and read more of the manual. Manual-1 FRONT PANEL DESCRIPTION 1. POWER switch: Obediently turns the SSA 6 on and off every time you poke it with your finger (or other suitable object). All six Channels have delayed turn-on/instant turn-off relays to eliminate any switching transients. 2. THERMAL overload indicator: This red LED lights up if the SSA 6 becomes too hot, indicating that power has been removed from all six Channels. Be sure to check the fan filter and actual speaker impedances if this lights up. 3. POWER indicator: This magnificent blue LED lights whenever the SSA 6 POWER switch is turned on. 4. READY indicators: Each of these green LEDs light whenever the mute relay is passing the signal through to the speaker. Normal operation is the on status. 5. LOAD LIMIT indicators: Each of these red LEDs lights whenever a Channel leaves the Safe Operating Area (SOA). This means the amplifier turned down the Input level quickly and automatically, avoiding over-dissipation. Input signals 30 dB over a safe limit will cause the READY indicator and mute relay to turn off until the amplifier has been turned off and the problem corrected. Normal operation is the off status. 6. PEAK LIMIT indicators: These red LEDs light whenever a Channel's Output cannot follow its Input. The amplifier has turned down the Input level quickly and automatically, avoiding audible distortion. Normal operation is the off stat

a. Be sure that all sil pads (insulators) are in place on the heatsink. SSA 6 SERVICE INFORMATION CAUTION: THESE SERVICING INSTRUCTIONS ARE FOR USE BY QUALIFIED SERVICE PERSONNEL ONLY. TO AVOID ELECTRIC SHOCK DO NOT PERFORM ANY SERVICING OTHER THAN THAT CONTAINED IN THE OPERATING INSTRUCTIONS UNLESS YOU ARE QUALIFIED TO DO SO. REFER ALL SERVICING TO QUALIFIED RANE WARRANTY SERVICE STATIONS. b. Be sure the nylon shoulder washers are in place on the transistors (TO-220 cases). Install the #4-40 screws in these and snug up only: Do not overtighten these driver screws as this may damage the thin shoulder washers and cause a short. c. Install the remaining 4 ea. #4-40 screws on the output and tighten these firmly to ensure proper heat transfer to the heatsink. d. Resolder the wires to the adjacent card. Be careful to connect them properly. B to B and A to A--pay attention to which A hole, these are different on even and odd channels as shown below. Disassembly Procedure CAUTION: WAIT ABOUT 15 MINUTES AFTER THE AMPLIFIER HAS BEEN POWERED DOWN BEFORE BEGINNING DISASSEMBLY PROCEDURE, TO ALLOW THE POWER SUPPLY CAPACITORS TO DISCHARGE. 1. Remove the bottom cover: 4 ea. #6 x 3/8" phillips screws on the side rails and 10 ea. #6 x ј" phillips screws on the edges of the bottom cover. 2. To remove a module (PCB card): a. Remove the input/output plate on the rear panel by removing 7 phillips screws and 12 ea. #4 tapping screws from the Euroblocks. b. Remove the 7 torx screws on the front panel just below the Level controls. c. Remove the 8 ea. #6/32xѕ" machine screws from the left and right edges of the heatsink mounting flange. Now the entire heatsink/module assembly is free to slide to the rear­this will provide the clearance necessary to remove any of the six amp modules. d. To remove a module, first de-solder the wires running to the adjacent card. Be sure to note the location of all wires for later reassembly (A to A, B to B). Then remove 7 ea. of the #4-40 machine screws holding the output, driver and bias transistors to the heatsink. Now pull firmly straight up to disengage the module from the connector­use a rocking motion to ease removal, as the connector is very tight. NOTE: Be sure that all of the transistor sil pads (insulators) stay on the heatsink­some of these may stick on the transistor and be inadvertently lost or thrown away with the defective component. New pads should be used whenever possible. 3. Module replacement: Factory supplied modules are pre-tuned and ready for installation. If you have made repairs on a module, be sure that ALL diodes are measured and replaced as necessary prior to installation of the module. e. Slide heatsink assembly forward so that all LEDs are properly aligned in the front panel holes. Install and tighten the 8 heatsink mounting screws. f. Replace the seven screws on the front panel. g. Replace the input/output plate and bottom cover (don't forget the four screws holding the bottom cover to the side rails). 4
