    30 minutes to acclimate to a new temperature before connecting to the ac mains and operating. 20. EAW loudspeakers can produce sound levels capable of causing permanent hearing damage from prolonged exposure. The higher the sound level, the less exposure needed to cause such damage.

  • Page 5: Precauzioni Di Sicurezza - Da Leggere Per Primo

    30 minutes avant de relier l'appareil au secteu et de l'utiliser. 20. Les enceintes EAW peuvent produire des niveaux sonores capables de causer des dommages irréversibles à l'audition en présence d'une exposition prolongée. Plus le niveau sonore est élevé, moins la durée d'exposition est longue avantde causer de tels dommages.
  • Page 6 30 minuti, prima di collegarlo alla presa di corrente e inizare l'utilizzo. 20. I diffusori EAW sono in grado di generare livelli sonori che possono causare danni permanenti all'udito in caso di esposizione prolungata. Maggiore è il livello del segnale audio, minore è il tempo di esposizione necessario a causare ali danni.

EAW Lautsprecher können Schalldruckpegel produzieren, die permanente Gehörschäden nach sich ziehen, wenn man sich diesen Pegeln zu lange aussetzt. Je höher der Pgel, desto weniger Zeit wird benötigt, um einen Gehörschaden zu verursachen.

    4.2.1 AC MAINS VOLTAGE The UX8800 has a universal, auto-ranging power supply that operates from 100 V to 240 V, 50 Hz to 60 Hz. The UX8800 is compatible with these nominal ac mains: 100 V, 110 V, 115 V, 120 V, 127 V, 220 V, 230 V, and 240 V at 50 Hz to 60 Hz.

  • Page 16: Audio Connections

    N e t w o r k C o n n e c t i o n s 4.4.1 ETHERNET The UX8800 communicates with a computer through its built-in, front panel, Ethernet port. This port is U-NET configured as a standard NIC (network interface card). The UX8800 can be connected to an Ethernet network using hub, switch, router, or wireless connections.
  • Page 17 OSI model (Open Systems Interconnection Reference Model). A computer’s Ethernet port, meaning its NIC (network interface card), and the UX8800 are both OSI layer 3 ports. Therefore, an Ethernet crossover cable is REQUIRED when directly connecting the UX8800 to a computer’s NIC.
  • Page 18 Operating System: I/O: The latest EAWPilot can be downloaded from the EAW web site: www.eaw.com. Go to the “Downloads” page or contact the factory and a copy will be sent to you on a CD-ROM. Once installed and with the computer connected to the UX8800, open EAWPilot by clicking on EAWPilot in the Start/Programs/EAW/EAWPilot.

  • Page 19: Operation - Initial Setup

    Use the UX8800’s rear panel power switch to turn the ac mains supply to the processor on and off. Always follow prudent audio system practices and procedures for powering on equipment by powering up all equipment in the direction of the signal flow order, meaning from the input to the output of the audio system.

  • Page 20: Util (System Set-Up)

    Select the signal, Analog or AES (=AES/EBU), for Inputs A&B and Inputs C&D. The sample rate for the AES signal can be 44.1 kHz, 48 kHz, 88.2 kHz, or 96 kHz. The sample-rate converter in the UX8800 will convert the input sample rates to 48 kHz sample rate required for its internal processing.
  • Page 21 Manually enter an IP address, normally a “private” IP address. The first three number groups in the IP address must be the same for both the computer and the UX8800. For example: 192.168.0.N, with N being an integer from 1 to 254, unique to each device.

    U-NET OUT ASSIGN Assign the summed, unprocessed sources to a U-Net output channel. This is useful for daisy-chaining a single analog or AES source signal to multiple UX8800 units. 6 . 5 C H ( O u t p u t C h a n n e l s 1 t o 8 ) Use the CH function to set the parameters for Output Channels 1 to 8 by selecting the 1 to 8 buttons.

    6 . 1 0 P R O G 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.

  • Page 25: Operation - Loudspeaker Processor Mode

    I n t r o d u c t i o n 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.

  • Page 26: Signal Routing

    System Processor mode with all input and output parameters fully user adjustable. When set for generic processing, the Input Channel processing can be adjusted using the UX8800 front panel. However, Output Channel processing can only be adjusted using EAWPilot software. It cannot be adjusted from the UX8800 front panel.

  • Page 27: Ch (Output Channels 1 To 8)

    Scroll through and select the Amp Gain for the amplifier connected to that output channel. The range is from 10 dB to 50 dB in 1 dB increments. This value is used by the UX8800 to determine the Output Channel gain and limiter threshold setting.

  • Page 28: Level (Input Channels A To D)

    LISTENER DISTANCE AND AIR LOSS PRE-EMPHASIS 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.

    Ensure the power cord is properly connected at both ends and that the ac mains is working. The UX8800 is deigned for an ac mains voltage between 100 V and 240 V, 50 Hz to 60 Hz. If outside these ranges, the UX8800 may fail to operate or become damaged.
