AY2658 Auxiliary Master/Tone/Talkback
Oscillator with 6 fixed frequencies. +10dB trim from central detented line-up position. Tone can be routed to up to 8 Groups - mono or stereo and to Main outputs 1 & 2 when the level is fixed at 0dBu for the Mono outputs and -3dB for the stereo outputs with two optional systems for left/right identification set up in the Output modules LN2656/LC2657. In-built talk-back capacitor microphone. Talk-back & reverse talk-back level controls. Momentary Talk-back selections to Groups, Main 1, Main 2, Auxiliaries - as selected on individual controls, External 1, 2 & 3 and Master which activates all destinations (except the Auxiliaries not selected). 4 Auxiliary Master gain controls - these controls and the channels have 10dB in hand at the line-up position. There are separate direct Auxiliary inputs and provision for post fader inserts. The reverse talkback feed forward to the Monitor module for mixing to the PFL loudspeaker is controlled by a remote switch line from the studio. The talkback can be linked to dim or cut the main monitor loudspeakers. EXTI can be connected to SLS - studio loudspeaker talkback if this module is fitted in medium, large or jumbo consoles.

ML2659 L.S. Monitor
AFL lamp illuminates when any AFL button is depressed. Headphone jack socket hears the same selections as the Monitor loudspeakers with separate Gain control but without Dim or Cut. The PFL mixed level is controlled by a gain control before being mixed with reverse talk-back and passing to the PFL/RTB loudspeaker. This does not affect the PFL monitor level. Selection of PFL to the Main Monitor selector bank, mutes the feed to the PFL/RTB loudpseaker. PFL may internally be switched to operate similarly to AFL over-riding the Main Monitor loudspeaker. The PFL/RTB loudspeaker is then only used for RTB and not necessary if this is not required. The AFL mixed level is also controlled by a separate gain control without affecting the mixed AFL and PFL signal - APFL - fed to the metering There is a separate PFL direct input There are 2 sets of Monitor selector banks : A and B Monitor A includes the console principal outputs Note that the right hand selections are selected on one of the left hand buttons in each set A separate SEL B button allows monitor comparisons There are in total 12 balanced stereo external monitor inputs A1-A4 and B1-B8 are external stereo inputs (usually from a jackfield) The Monitor loudspeaker signals as selected which may be substituted by an in place AFL signal (or more than one), (and with the PFL signal if so selected) pass through an Optional Phase Reverse circuit (Right only), Mono Left or Mono Both selections, Gain and Balance controls with provision for local or external dim and cut

IY2660 Mono Fader , IY2742 Stereo Fader IY2743 Mono VCA Fader , IY2744 Stereo VCA Fader The appropriate fader is fitted to the Channels, Groups and Outputs. The standard faders are normally fitted, VCA types being an option. The PEAK lamp operates from the associated module. The REMT lamp is illuminated when the fader is open to indicate ON or remote start. PFL operates on overpress in addition to the button.
CY2662 COMPRESSOR/LIMITER This stereo Compressor/Limiter is a separate unit for connection at the jackfield to Channels, Groups or Outputs (if the latter do not have in-built dynamics). Up to 6 units may be fitted to each chassis section - maximum of 24 in Jumbo chassis. Note that units may link to adjacent units. There are optional internal links for FAST & SLOW ATTACK : 0.1 & 0.5 msec; 2 & 10 msec.
