  • Page 19: Resolution Configuration

    Resolution Configuration 6. Configuring UXA Installation Amplifiers in Resolution 2 The Network View Processor shows an overview of the Zones and Outputs in the amplifier. Outputs that are fed by a Zone will appear beside the associated Zone The main window provides an overview of the amplifier state. The main sections of the amplifier can be navigated using the top-row tabs.
  • Page 20 Resolution Configuration The LAN and WIFI addresses are also shown and can help indicate if the proper network connections have been made. Each Zone on the amplifier is shown in the overview. Also indicated are the input source to the zone, and the output channels that the zone feeds.
  • Page 21 Resolution Configuration The input sensitivity can be controlled using the following buttons illustrated on the right. Each analog input has a five band equalizer. The type of each band can be changed to PEQ, High/Low pass, or High/Low shelf. In addition, there is a fixed 100Hz High Pass filter that may be toggled on or off. Each EQ point can be controlled in EQ Filters.
  • Page 22 Resolution Configuration Channel linking supports grouping channels that share a subset of EQ settings. Any adjustments made to a shared EQ control on one channel will be propagated to all channels in the group New groups can be created. The first channel added to the group will define the initial EQ settings. A channel can be added to a group by selecting the group number in the drop down box.
  • Page 23 Resolution Configuration The Mixer input channel supports mixing Analog, SPDIF, and Dante inputs into a single mixed input. Each input channel has a gain control and meters. The Generator input provides Sine Wave and Pink Noise signals as input sources. The volume limit of the generator can be set from -48dB to 0dB.
  • Page 24 Resolution Configuration 6.2 Zone Channels Tab Zones provide input control for outputs. Each zone has a primary input source and a priority source. The priority source can be set to automatically override the primary source, based on signal detection, for important announcements or emergencies. Zones support Stereo channels, volume level, and mute.
  • Page 25 Resolution Configuration The priority input selection defines an alternate input source used to interrupt the current signal when announcements or emergency signals need to be made. There are two modes for signal detection. Priority mode is used to interrupt the primary source signal when a minimum Threshold level is detected on the priority input.
  • Page 26 Resolution Configuration The Zone Volume controls are used to configure the range and external control of the Zone volume. “Volume Range” can be set to minimum and maximum values. Doing so will prevent the gain control from being adjusted beyond these limits. “Allow Mute”...
  • Page 27 Zones provide the input source to an Output channel. Each output has equalization and delay. EAW Greybox presets provide optimized settings for EAW loudspeakers. Each amplifier can store a library of speaker presets. Resolution comes with a list of the most recent preset revisions.
  • Page 28 Resolution Configuration The Routing section defines the Zone input source to the output channel. If the selected Zone source is a stereo input, then a the stereo channel must be chosen as the input to the Zone, or a sum of the ;eft and right channels. The output equalizer can be enabled or disabled on the output channel.

  • Page 30 Resolution Configuration The GPIO settings are used to specify what each GPIO pin is used for. For Zone Volume control, setting a GPIO, such as Pin 4, will allow that pin to be selected as the volume control on any Zone channel. Output routing is used to route input audio signals directly to S/PDIF or Dante outputs.
  • Page 31 Resolution Configuration The WIFI settings under the Network Tab control connection through the WIFI Under LAN Settings on the Network Tab the amplifier can be configured to have a DHCP or Static IP address. Changes must be applied to take effect. Power usage can be configured on the Power tab.
  • Page 32 Resolution Configuration This tab is useful for viewing differences between the preset library in Resolution and the library on the amplifier. Presets that are not available in both places are indicated by orange shading. The current library in Resolution can be sent to the amplifier using the Send button. Sending a preset library to the amplifier will overwrite its current library.
