OPERATORS MANUAL SAC 22 STEREO 2-WAY ACTIVE CROSSOVER QUICK START Whoa, hold on there. Even if you don't read manuals as a matter of principle, at least read this section to avoid hurting yourself or your equipment. Connect the SAC 22 with the power off. Balanced XLR cables are recommended, but if you must convert to ј" connectors, buy or make a cable like the ones on page Manual-11 and keep them as short as possible. This device uses low impedance balanced line drivers. Do not connect the "+" or "­" output pins to ground, as this may cause the power supply to shut down. For unbalanced use, leave the unused output pin ("+" or "­") unterminated. Consult the speaker manufacturer for the correct crossover FREQUENCY setting. As rugged as some drivers are, many (especially compression drivers) will not accept frequencies outside of their normal range without producing distortion and possibly self-destruction. With all equipment turned off and LEVEL controls down, begin making connections to the system as shown on page Manual-4 or 5. When turning on the system, switch on the power amplifiers last. Now, feed the SAC 22 some program material. Start by turning up the LOW LEVEL and HIGH LEVEL to the 0 dB marks. Slowly increase the INPUT LEVEL, even if it goes all the way to 10, so the +4 dBu (green) light blinks occasionally and the OL (red) light stays out. This delivers the best signal-to-noise performance. The MONO SUB OUTPUT is a sum of the Left and Right Low Outputs. The MONO SUB LEVEL adjusts only this Output and is not affected by the LOW LEVEL control.. When using a single subwoofer along with full-range cabinets that have internal crossovers, set the 100 Hz FILTER to OUT, allowing the front panel FREQUENCY to control the subwoofer crossover point. When used with biamp cabinets and a subwoofer, set the 100 Hz FILTER switch to IN to allow only frequencies below 100 Hz at this output jack. This way, the SAC 22 almost does the job of a Stereo 3-Way crossover, but without removing that awesome bass from the Left and Right Low Outputs. WEAR PARTS: This product contains no wear parts. Manual-1 INPUT LEVEL control and indicators This controls the overall level without altering the relative settings of the Low and High frequency Outputs. Input gain is +6 dB at "10". With signal applied, set this control so the +4 dBu LED lights occasionally, indicating sufficient signal. Flashing of the OL (overload) LED during peaks can be avoided by turning the INPUT LEVEL down. MONO SUB OUTPUT LEVEL control This controls the level of the summed signals of the LEFT and RIGHT LOW OUTPUTS. It may be used instead of, or along with the LOW OUTPUTS. The output may be adjusted with the LEVEL trim from +0 dB to OFF. Unity gain is reached at the "0 dB" mark with the INPUT LEVEL set to "10". LOW LEVEL control This controls the level of signal going to the LOW OUTPUT jacks. Unity gain is reached at the "0 dB" mark with the INPUT LEVEL set to "10". This control does not aff
