    RF signal coverage areas, the amount of perceived multipath is reduced as well, resulting in the perception of a much cleaner overall signal with better penetration and coverage. The Omnia.11 defaults to a setting of Stereo, using the full L-R signal for maximum separation. We suggest that you leave it in that mode, but the other settings are available for those who wish to experiment, including a setting of full Mono.
  • Page 39: Fm Options

    In certain parts of the world, the average multiplex signal power must be controlled to reduce adjacent channel interference. The currently enforced standard falls under the ITU BS-412 regulations. The Omnia.11 FM has a very effective Multiplex Power Limiter that may be enabled to comply with these regulations.
  • Page 40: Diversity Delay

    Diversity Delay The 3 buttons below the numerical diversity delay time display are used to set the precise diversity delay time (typically used for HD Radio installations) that will be applied to any output that is set to the FM channel. If diversity delay is not used, be sure the numerical display is showing all zeros.

    “smart” enough to know whether a program element is pre-processed or not and act accordingly. The Omnia.11 is able to do as little further “damage” as possible to already processed content (such as a song from a modern hyper-compressed CD) while acting more aggressively on more dynamic, less pre-processed material.

    Vocals will stay up-front and the sonic details of musical instruments will be heard with an apparent slight loudness increase. The Stereo Enh control has a range of “0.0” (OFF) to 11 and the amount of dynamic width expansion can be observed on the rightmost vertical bargraph marked “ST” in the Meter Area. The system should be initially auditioned using light amounts of stereo enhancement, with an initial setting of 4 to 6 recommended as a starting point.
  • Page 53: Agc

    The 5-Band AGC section works on the average level of the program material and can act both as a dynamic equalizer and as a compressor/leveler depending on settings and the dynamics in the program material itself. There are 3 control groups in the 5-Band AGC section, XO, AGC and Mixer: The output of the Wide Band AGC section feeds the 5-Band AGC section through a crossover.
  • Page 54: Agc Metering (Summary Tab)

    AGC Metering (Summary Tab) The 5 gain reduction meters show AGC activity from the top down in dB and the AGC crossover frequencies in use are shown just above the gain reduction meters. Gating is indicated by bright yellow outlines around the blue gain-reduction meters.

    Makeup Gain: Sets the amount of gain to be filled in during quieter, softer program passages. The range is “0.0” (off) to “11” (maximum). This function is also program dependent, and it interacts somewhat with the main Attack and Release time constants. As the attack/release times are modified, the system also scales the Make-Up Gain time constants.

    Limiters Crossover (Advanced Tab) The 2 drop-down controls in the Limiters crossover Advanced tab allow you to modify the crossover frequency points of the LO (LO to ML) and SL (SL to LO) limiter bands. The ML to MH, MH to HI and HI to SH crossover points are not adjustable.
  • Page 60: Limiters (Basic Tab)

    Limiters (Basic Tab) There are 4 variable controls in the Limiters menu area and all of them are “global”. That is, they affect all 6 limiter bands simultaneously and equally. The first global control is an overall Drive control that allows you to adjust the amount of gain reduction in the entire 6-Band Limiter section at once.
  • Page 61 Care is needed when adjusting this control because higher settings will cause less limiting to occur, and the resulting uncontrolled peak energy will go to the following final limiter/clipper stages instead. Thus, with this control you can artistically trade off dynamic limiting against brick wall final limiting/clipping, as each has its own “sound.” As the limiter threshold is lowered, (made more negative) the peak output level of the limiter is reduced.

  • Page 66: Hd Final Limiter (Basic Tab)

    HD Final Limiter (Basic Tab) The HD channel employs an advanced look-ahead limiter to provide absolute precision peak control. This limiter as been designed to minimize processing side-effects like IM distortion, which are usually associated with limiters of this type. This allows this limiter to sound extremely transparent. This type of peak controller is used instead of a clipper because it does not generate the same high levels of harmonic distortion as a Clipper does.
