[. . . ] Cables with Speakon connectors are recommended because of the high power/current output of the 2000RB. Refer to the section titled "SELECTING AN OPERATING MODE AND HOOKING UP YOUR SPEAKERS" for recommended Speakon cables. (continues on the next page) 5 (45) & (46) 1/4'' CONNECTORS Provided as back-up outputs for the RIGHT/HIGH channel. 1/4'' connectors do not have the same power handling as Speakon connectors, and should only be used if Speakon cable are unavailable. Caution : You may not connect less than a 4 ohm load to either of these 1/4'' connectors. (47) & (48) SPEAKON CONNECTORS Deliver power from the LEFT channel ( if you are in "Stereo MODE"), LOW channel ( if you are in "Bi-amp Mode"), or BRIDGED ( if you are in "Bridge Mode") to your speaker(s). Cables with Speakon connectors are recommended because of the high power/current output of the 2000RB. Refer to section title "CHOOSE AN OPERATING MODE AND HOOK UP YOUR SPEAKERS" for recommended Speakon cables. Remember, if you are in the "Bridge Mode", you will need special Speakon Bridge Cables. (49) & (50) 1/4'' CONNECTORS Provided as back-up outputs for the LEFT/LOW channel. 1/4'' connectors do not have the same power handling as Speakon connectors, and should only be used if Speakon cables are unavailable. Caution : You may not connect less than a 4 ohm load to either of these 1/4'' connectors. If you are in "Bridge Mode" these 1/4'' connectors are not functional. Note: You can not operate the 2000RB in 6 STEREO MODE: "Stereo Mode" is used when you want a stereo output, or when your speakers are not the optimum impedance for "Bridge Mode". For example, if you happen to own two 4 ohm speaker cabinets, you can not use both at the same time in "Bridge Mode". However, in "Stereo Mode", each channel can drive up to two 4 ohm speakers or four 8 ohm speakers (total of 2 ohms per channel). In "Stereo Mode", each of the 2000RB's power amps operates independently, and delivers 500 watts into 2 ohms. Note: Using fewer speakers (greater than 2 ohms per channel) is OK. Using more speaker cabinets (below 2 ohms per channel) is not recommended, and could result in the Fault Detection System disconnecting the 2000RB's output. For "Stereo Mode" turn the BRIDGE MODE switch (42) to the OFF position. The BIAMP switch (33) should be in the FULL RANGE position. Then connect the RIGHT channel to your speakers via Speakon connectors (43) & (44), and if necessary, with 1/4'' jacks (45) and (46). Remember you can not connect less than a 4 ohm load to either of the 1/4'' jacks. Connect the LEFT channel to your speakers via Speakon connectors (47) & (48), and if necessary, with 1/4'' jacks (49) and (50). [. . . ] Note : This configuration will add extra low end (whether your effects are on or off), so you may have to adjust your EQ to compensate. If you want effects on your highs and lows (full range) : Take SEND (36) into the "mono" input of your effects unit. Take the stereo outputs from your from your effects unit through an adapter and into STEREO AUX IN (30). Use AUX LEVEL (19) on the front panel to control your effects blend. For effects on the high-end only. [. . . ]
