PDF Content Summary:
****** Page 1 ****** AUDIO, INC. ASHLY MODEL SC-77 ASHLY The SC-77 Stereo Three-Way Electronic Cross- over is designed to fill the needs of modern high power sound systems, Crossover points and rolloff are continuously adjustable and individ- ual output stages with wide range gain adjust- ments will drive long cable runs and accurately match any power amplifiers. FEATURES: o 2 dB per octave slopes Logical control layout Both the inputs and outputs can be used balanced or unbalanced Flat summing Rugged 16 gauge steel chassis Peak overlaod warning lights In-phase outputs Our exclusive rolloff control to flatten frequency response at the crossover point Optional 5-way mono operation
****** Page 2 ****** O 00 0 0 oöo The SC-77 uses state variable filter circuits to perform the frequency divisions. These filters provide simulta- neous low-pass and high-passoutputs. Two filters are cascaded for three-way operation. Inverters are included on the mid outputs to keep everything in- phase. A “Q” adjustment (called rolloff) is included for adjustment of frequency response in the cross- over region. This allows flat summing and in-phase outputs. BAIANCEO GAIN FROM FROM FROM OUIPUI INPUI STAGES HI INDICATOR POWER MONI’OP ASHLY cowecrto OR The output stages have a wide range gain adjust- ment with a special feedback level control circuit to maintain an optimum signal-to-noise ratio at any setting. A special electronic power monitor for the output stages prevents turn-on transients without the use of relays. Both inputs and outputs can be used as balanced or unbalanced and a peak overload circuit monitors all critical points in the circuit to insure low-distortion operation.
