UX48 Owners Manual19such as to add ‘Throw’ EQ boost so that parts of cluster which are throwing further can have HF absorptioncorrection added. If this EQ is not linear phase, then the zones where the speakers combine may suffer frequencyresponse anomalies.Being a linear phase FIR equalizer, this necessarily introduces some latency delay, which is constant regardless ofthe settings. However, when the ‘Enable’ parameter is set to “Off”, it is removed from the signal path entirely, soit does not add any latency. In this page you can change the frequency parameter from 2kHz to 20kHz, enable/disable the filter, and change the cut or boost in 0.2dB increments. The filter (and its associated latency) can becompletely removed by setting the enable parameter to the “Off” position.Also see Bandwidth Units in Utilities.Parametric FiltersParametric filters are defined by frequency, bandwidth and gain. The frequency is controlled by encoder “A” andranges from 10Hz to 25.6kHz. The bandwidth, shown as Width on the screen, is controlled by encoder “B” andranges from 0.10 octaves to 5.2 octaves. Bandwidth can be shown and adjusted as Q or Octaves (Oct). Gain iscontrolled by encoder “C” and is adjusted in 0.2dB increments. .Also see Bandwidth Units in Utilities.RoutingRouting allows users to route any physical Analog or digital signal channel to any DSP input. This is effectivelya matrix mixing system where all DSPs can be driven from any one input, or from pairs of inputs “1+2”, “3+4”,“1+3”, “1+4”, “2+3”, “2+4”, “1+2+3” or “1+2+3+4”. Summed inputs have 6dB of attenuation so that a sum oflargely similar programme material remains at the correct calibrated level.OutputAES3 outputsIn addition to the usual Analog outputs, the UX48 also allows outputs to be sent digitally using AES3. The samephysical XLR sockets are used for both Analog and AES3 outputs; the function of these being determined by theXLR parameters in the Output Route menu. The Odd numbered output sockets are used to output pairs of AES3channels. When an output socket is selected for AES3 operation, the “AES3” indicator under the output bar graphswill illuminate.The output sample rate for AES3 will always be 48kHz. The calibration between Analog and AES3 levels is 0dBFS(AES3) = +20dBu (Analog).Gain and PolarityThe gain page of the output channel allows users to increase or decrease the relative signal gain for the selectedoutput. Using encoder “A” will change the value in 0.2dB steps from -40dB to +20dB. This page will also allowusers to change the polarity of the selected output from normal to reverse, using encoder “B”.DelayThe delay page controls the amount of delay associated with the output channel selected and is adjustable from0 to 998ms. The delay parameter is adjustable in fine steps at low values; the adjustment becomes progressivelycoarser as the value increases.
