Ow ning a Sou nd craft console brings you the exp ertise and su p p ort of one of the ind u stry's lead ing m anu factu rers and the resu lts of over 20 years exp erience su p p orting som e of the biggest nam es in the bu siness. Designed by engineers w ho u nd erstand the ind ivid u al need s of m u sicians, SPIRIT LIVE 4 has been bu ilt to the highest stand ard s u sing qu ality Jap anese com p onents and em p loying au tom ated assem bly techniqu es beyond the reach of m ost m anu factu rers of com p act m ixers. A ru gged steel chassis is com bined w ith m ou ld ed sid e trim s to give p rotection and d istinctive ap p earance. [. . . ] All of the Au x Send s are m u ted w hen the ON sw itch(12) is released . Pa g e 13 INPUT 10. PAN The PAN control d eterm ines the p osition of the signal w ithin the stereo m ix im age or m ay be u sed to rou te the channel signal to p articu lar ou tp u t GROUPS as selected by the ROUTIN G SWITCHES (13). Rotation fu lly anticlockw ise feed s the signal solely to the Left m ix bu ss or Grou p s 1 and 3, w hile rotation clockw ise sw eep s the im age to the right bu ss or Grou p s 2 and 4. PFL/ PEAK LED When the PFL sw itch is p ressed , the Pre-Fad e signal is fed to the head p hones, w here it rep laces the selected sou rce. The PFL/AFL LED on the m aster section illu m inates to w arn that the head p hones and the m eters are now resp ond ing to the PFL/ AFL selection and the PFL LED on the inp u t channel lights to id entify the active channel. This is a u sefu l w ay of listening to any requ ired inp u t signal w ithou t interru p ting the m ain m ix, for m aking ad ju stm ents or tracing p roblem s. When the PFL sw itch is released the LED on the channel serves as a PEAK ind icator, to w arn w hen an excessively high signal level is p resent in the channel. The signal is sam p led at tw o p oints in the channel, im m ed iately after the inp u t am p lifier (PRE H I-PASS FILTER & PRE IN SERT) and POST EQ. The Peak LED w ill illu m inate ap p roxim ately 4d B before clip p ing and therefore give w arning of a p ossible overload even if the p eaks are rem oved by external equ ip m ent p lu gged into the Insert. O N SWITC H The ON sw itch enables all ou tp u ts from the channel w hen p ressed , and the associated LED illu m inates to show that the channel is active. RO UTING SWITC HES The inp u t channel signal m ay be rou ted to the m ain STEREO MIX (L-R) or p airs of GROUP bu sses (1-2, 3-4), by p ressing the resp ective sw itches. These m ay be u sed in conju nction w ith the PAN control (10 above) to rou te the channel signal p rop ortionately to any of the selected bu sses. C HANNEL FADER This long-throw fad er d eterm ines the p rop ortion of the channel in the m ix and p rovid es a clear visu al ind ication of channel level. N orm al op erating p osition is at the `0' m ark, p rovid ing 10d B of gain above that p oint if requ ired . Pa g e 14 STEREO STEREO SECTIONS 1. STEREO INPUTS Each Stereo Inp u t section com p rises a p air of sim ilar inp u ts. The inp u ts are electronically balanced and sep arate jacks are p rovid ed for the Left and Right sou rce signals. A m ono signal m ay be p lu gged into the u p p er socket only for each p air to be fed equ ally to left and right bu sses. - 10 SWITC H The inp u t jacks are norm ally set to m atch +4d Bu nom inal signal levels. Pressing the -10 sw itch alters the inp u t sensitivity to m atch the -10d BV signals from m ost H i-Fi system s or sem i-p rofessional tap e m achines allow ing the inp u ts to be qu ickly sw itched to m atch, for instance, a cassette p layer for p re-show m u sic. EQ UALISATIO N Each Stereo Inp u t is p rovid ed w ith a 2-band shelving EQ section giving ±15d B boost & cu t at fixed frequ encies of 60H z and 12kH z.
