  • Page 3 JCF Audio Overview Welcome to the JCF Audio JCN manual. Anyone who has worked with or at least is familiar with inline consoles will hopefully find this a snap with a few added bonuses. Refer to the block diagrams as you read this text. In many cases, the picture will say more than the text practically can.
  • Page 4 JCF Audio 5)The Meters (x8)- The master meters can be sourced from 3 points selected on the master mod- ule associated with the same number meter (The default selection “MO” is a carry-up from the studio output section of the monitor controller so that metering can be sourced from all moni- torable points in the console independent of what appears on the CR speakers.

  • Page 6 JCF Audio Transport and Options Panel Listen Functions: 1-8: momentary switches that will immediately solo the associated listen mic input. These but- tons will also toggle the status of that listen channel in the group if the group is active (on).

The mute command from the DAW is passed onto either on-board mute based on this selection.
  • Page 9 JCF Audio Record (mom) - Master status rake for all modules. Unselects all B,C,D assignments. Mix (mom)- Master status rake for all modules. Unselects all B,C,D assignments as well. If Frc- Spl selected, the Mix rake command will invoke monitor to stereo buss assignment for double the number of Mix inputs to the stereo buss.
  • Page 10 JCF Audio Open (1mom and 1lat) - at the top of each column there is one switch that is unassigned that can be for application specific tasks. The illustration shows these dedicated to changing the il- lumination colors of the monitor panel and turning external PEP processing on and off.
  • Page 11 JCF Audio The right column has two surround sources available. The 8 buss points (analog, St. B, C, D) with “St” being what should be selected for the group is one. The D1 (digital, 8 channel set that includes D2, and the two sets that are present but not available as sources by themselves: D3 and D4) is the other.
  • Page 12 JCF Audio Master module section: Master modules 1, 3, and 5 are essentially the same with odd numbered echo return assign- ments. Modules 2, 4, and 6 are also the same with even numbered echo return assignments. Master modules 7 and 8 do not have aux master controls or LTA controls as there are only 6 aux sends.
  • Page 13 JCF Audio The first control at the top blends or crossfades between the direct tie from the buss amp box on the buss number that matches the module and its “wet” input. (“Wet” in this case refers to that which is influenced by the insert path. It does not refer to echo returns.) This control blends in whatever is in the insert path which includes the 500 series slot and the external insert patch path in that order.
  • Page 14 JCF Audio The listen mic / echo output that is available on the 26 pin output under the Master Module motherboard can be selected with jumpers on the module to be: On all of the time Switched on via group An on all the time echo return post fader output Tsh is the threshold control for the module’s dynamics section.

  • Page 19 JCF Audio Both of the digital inputs can be selected to be on with the DCh. and/or DMn. master controls, but they must be turned off individually. +48 assigns phantom power to the Mic input and will additionally apply phantom power to the Line 1 input for all modules in Rec status while FrcSpl is engaged.

  • Page 21 JCF Audio Bottom to Top: The main mute and solo controls influence the path associated with the large fader. (Channel in mix, Monitor in record) The mute can be enacted by PFL logic, carried up from the DAW control mute, or manually.
  • Page 22 JCF Audio The MI/O button selects either the normal input to the monitor path or the Line2 input which is generally normalled down from the Channel path direct output. This allows for a non-latent source of signal directly from the channel path which can be automatically (or manually) switched (when armed by pressing the button, engaging AtMn in the master section, and being in the appropriate transport status).

  • Page 24: Operation

    JCF Audio Operation Mix mode: Overlapping assignment with insert engaged causes the monitor path buss assignment discon- nect to avoid unnecessary addition of common signals (without FrcSpl global) Overlapping assignment will cause the fader to become a crossfader between paths for insert crossfading (without FrcSpl global).
  • Page 25 JCF Audio from the post-monitor signal only (feedback). Insert doesn’t apply here and if invoked will mute the monitor path output. (Monitor path available sources are “L1” (A or DCh), DMon) FrcSpl in this mode would simply apply a feedback limiter to the short fader path. (Monitor path available sources are “L1”...
  • Page 26 JCF Audio and/or filtering is applied prior to the limiting. For the feedforward sections listed above the post-insert, pre on-board eq channel signal is the signal that the limiting control is generated from. For the feedback sections above the limiting control signal reflects the whole of the equalizer (and dynamics itself, hence feedback) ——————————————...
  • Page 27 JCF Audio ——————————————— Recall Operation When WrtAt is pushed, all modules will interrupt their output data flow to put out a very short (<1 sec) pulse of information into the AES stream. This information is stored most easily on a 1:1 basis with the audio tracks in the given session.
