EQ UALISER The Equ aliser(EQ) com p rises three sections. The u p p er control p rovid es H . F. (treble) boost and cu t of +/ -15d B. The low er tw o p airs of knobs are arranged as a cu t/ boost control (low er knob) of +/ - 15d B, and a SWEEP(frequ ency) control w hich d eterm ines at w hich frequ ency the boost/ cu t action w ill be centered . The LF sections are essentially Sw ep t Low Frequ ency controls, covering a range from 40 to 400H z and p rovid ing m u ch greater flexibility than a conventional LF(bass) control. The MID section, w ith a frequ ency range from 250H z to 8kH z is p articu larly versatile for vocals, enabling p articu lar characteristics of the singer to be lifted or su p p ressed very p recisely.

AUXILIARY SENDS These controls rou te the inp u t channel signal to any one or m ore Au xiliary bu sses. These are sep arate from the m ain ou tp u ts and can therefore p rovid e ad d itional ou tp u ts for fold back, echo u nits or extra lou d sp eaker `fills'. AUX 1 & 2 are d erived before the channel fad er(PRE FADE), and are therefore u naffected by the fad er p osition. This m akes them p articu larly su itable for fold back or m onitor feed s, w hich need to be controlled sep arately from the m ain P. A. AUX 3, 4 and 5 are d erived after the channel fad er(POST FADE), and therefore follow any changes in fad er level. AUX SEND A single control feed s a m ono su m of the stereo signal to a choice of Au x Send bu sses (see 5 below ). AUX SELEC TIO N The flexibility of the Au x send control (4) is m axim ised by a choice of d estinations on the tw o Stereo sections. On the u p p er section (Stereo 1) this sw itch rou tes the Au x Send to either AUX 1 (Prefad e) w hen released , or AUX 3 (Postfad e) w hen p ressed . On the low er section the choice is betw een AUX 1 (Prefad e) w hen released and AUX 4 (Postfad e) w hen p ressed . BALANC E The BAL control sets the relative level of the Left and Right signals. Tu rning the control fu lly clockw ise increases the Right signal by +4d B, and totally kills the Left signal. Balance left biases the signal to the Left bu ss and Grou p s 1 & 3, balance right to the Right bu ss and Grou p s 2 & 4. PFL When the PFL sw itch is p ressed the p refad e signal is fed to the H ead p hones w here it rep laces the selected sou rce. The AFL/PFL LED on the Master Section illu m inates to w arn that the head p hones and RIGHT/PFL METER are now resp ond ing to the PFL selection and the PFL LED on the Stereo Section lights to id entify the active sou rce. ON Pressing this sw itch tu rns ON the feed s to the Au x Send s and ou tp u t bu sses. RO UTING A single Rou ting Sw itch p er section p rovid es access to Mix L-R and Grou p s 1-2 or 3-4.
