5.3.5 HUMIDITY This is only functional in Loudspeaker Processor mode. Enter the relative humidity. This value is used to calculate the Air Loss Pre-emphasis filters. The air loss depends on the temperature, humidity, and distance to the listeners. The humidity is adjustable between 10% and 100% in 1% increments. Below 10%, the absorptive properties of air have not been well quantified. If in System Processor mode, this setting may be ignored. 5.3.
6 OPERATION - SYSTEM PROCESSOR MODE 6.1 Introduction System Processor mode configures the processor for standard, digital signal processing functions. These functions consist of Input Channel and Output Channel processing that includes equalization filters, signal delay, polarity, gain, crossover filters, limiting, and high/low-pass filters. All parameters are user accessible and user adjustable. 6.2 Select System Processor Mode 1. Select the UTIL function. 2. Scroll down to and select: Mode 3.
6.5.2 U-NET OUT ASSIGN Assign the processed output signal to a U-Net output channel: U-Net 1 to 32 6.5.3 CHANNEL NAME Enter a name for the output channel, up to 16 alphanumeric characters. 6.6 LEVEL Use the LEVEL function to set Input Channel and Output Channel gain and polarity by selecting the A to D or 1 to 8 buttons. Level: Polarity: 6.7 Scroll through and select the gain up to +/- 15 dB in 0.1 dB steps. Select the polarity: + or -.
6.10 PROG The UX8800 has memory spaces for 50 user-savable and loadable programs for each operating mode (Loudspeaker Processor and System Processor). NOTE: The unit will only display programs stored in memory for the current operating mode: System Processor or Loudspeaker Processor. Load Scroll through existing programs stored in the processor memories to find and load the desired program. A program contains information for all processing parameters except for the mute settings.
7 OPERATION - LOUDSPEAKER PROCESSOR MODE IMPORTANT NOTE: In this mode only certain functions and parameters are available for user adjustment. These will vary depending on the input configuration and the specific loudspeaker or array selected by the user. 7.1 Introduction In Loudspeaker Processor mode the user can select from a list of specific EAW loudspeaker models and arrays with factory-determined processor settings. This processing is not user accessible or adjustable.
7.3 Signal Routing In order to pass signal, these tasks must be completed, as detailed in the sections listed. 1. Select the type of input signal connected to the XLR input connectors (5.3.3). 2. Assign one or two sources (input connector signals) to each input channel (7.4.1). 3. For each input channel, select a Greybox or Generic Processing (7.4.2). 4. Assign each Greybox or Generic Processing leg to an output channel (7.4.2.5). 7.
NOTES: The Amp Gain, Max Voltage, and Listener Distance can be adjusted at any time by selecting the CH function and the desired Output Channel then editing these parameters. The HPF and LPF filters can be adjusted at any time by selecting the X-over function and the desired Input Channel then editing these parameters. 7.4.3 U-NET OUTPUT Assign the summed, unprocessed sources to a U-Net output channel. This is useful for daisy-chaining an analog or AES source signal to multiple UX8800 units. 7.4.
7.5.5 LISTENER DISTANCE AND AIR LOSS PRE-EMPHASIS IMPORTANT !! In order for the Air Loss Pre-emphasis to be effective, the ambient temperature and humidity values MUST be manually entered using the UTIL menu on the UX8800's front panel. (See Sections 5.3.4 and 5.3.5.) If enabled, scroll through and set the Listener Distance (1 m to 256 m) from the array to the closest part of the audience area covered by the portion of the array to which the pre-emphasis is applied.
2. Loudspeakers and Arrays with Subwoofers: To use full-range loudspeakers and arrays with subwoofers, set the X-Over LPF and HPF filters to the desired subwoofer to full-range crossover frequencies. This automatically changes the HPF filters from their normal settings to a more appropriate filter, most commonly a 24 dB per octave Linkwitz-Riley filter. While the crossover frequencies are adjustable, the type and slope of the crossover filters are not adjustable.
LED INDICATORS 8.1 Ethernet The LEDs on the Ethernet connector indicate the Ethernet connection and activity status. Left Link LED Status Right Activity LED Status Amber color 10 Mbps Amber color Half duplex Green color 100 Mbps Green color Full duplex On Link established On/flashing Data activity Off No link Off No activity ETHERNET U-NET 1 8.2 2 The U-Net LEDs on the front/rear panels indicate the U-Net network status.
9 EAWPILOT 9.1 Extra Capabilities While the UX8800 interface window in EAWPilot software provides the same capabilities for controlling the UX8800 as its front panel controls, it also provides additional capabilities not available using the front panel controls. 9.1.1 LEVEL MONITORING - ANY MODE The meters in EAWPilot provide more accurate and much higher resolution signal level monitoring. Both the average and peak levels are easier to read and provide mush better tracking for critical situations. 9.
