User manual ELECTRO-VOICE DX38 EDS

[. . . ] Ordnung zur Realisierung von B-6 Alignments, oder spezielle LPN-Filter (Lowpass Notch / Tiefpaß-Sperrfilter) zur Korrektur des Frequenz- und Phasengangs von Baßreflexboxen. Zusätzlich ist jeder Kanal mit einem Delay, einem Polaritätswahlschalter, einem programmierbaren Pegelsteller und einem digitalen Kompressor / Limiter ausgestattet. In den Eingängen befinden sich außerdem noch die Master-Delays. [. . . ] Additional filtering is provided through 2. order high-passes for the realization of B-6 alignment, or special LPN-filters (Low-Pass Notch filters) for correcting the frequency and phase responses of optimally vented woofer cabinets. Each channel additionally provides a delay, a polarity switch, a programmable level control and a digital compressor / limiter while the master delays are located in the input channels. The user can choose between three operation modes: the "No Edit Mode" allows to simply select the required combination of loudspeaker systems from the factory preset program list. Afterwards, the appliance is optimally matched to the sound system and can be operated instantly. The "Standard Edit Mode" also uses a pre-set basic program but with the exception that here, the user has access to the selected amount of parameters. The "Full Edit Mode" on the other hand offers access to all parameters, allowing to freely program and store basically any setting. A total number of 80 memory addresses - 50 preset and 30 freely assignable user-programs - are available. Within the Dx 38, AD/DA conversion is taken care of by linear 24-bit converters; where the AD-section employs 128 times oversampling, gain-ranging Sigma-Delta converters. The DA-section offers 128 times oversampling Sigma-Delta converters. The overall signal processing is performed by two 24-bit Motorola signal processors. Additional features are: - FLASH memory for software and preset updates via serial interfaces - PC-based operation and configuration software running under Windows `95 / Windows `98 - Standard MIDI-interface - RS-232, RS-485 interfaces or switching contacts optionally available - Back-lit graphic-display with 122 x 32 dots - Inputs and outputs are electronically balanced, XLR-type connectors - Input transformer-balancing is optionally available - Input / Output level controls, Output-Mute switch, channel function indicators SUB, LO, MID, HI - Input / Output meter instruments, compressor and clipping LEDs Parmi les autres caractéristiques : - Mémoire FLASH pour le logiciel d'exploitation et les Presets, ce qui permet la mise à jour via interface série. - Logiciel de configuration et de commande pour PC, tournant sous Windows 95/98. - En option, commande via interfaces RS-232, RS-485 ou commutation par contacts. - Affichage graphique rétro-éclairé, 122 x 32 points. [. . . ] Dans ce cas, l'appareil est configuré de façon optimale en fonction de l'installation, et peut être exploité instantanément. Le mode "Standard Edit" part également d'un Programme Preset d'usine, mais permet cette fois à l'utilisateur d'accéder à un certain nombre de paramètres sélectionnés. Enfin, le mode "Full Edit", lui, permet d'accéder à tous les paramètres, ce qui permet de programmer en toute liberté et de mémoriser ses Programmes. [. . . ]
