ASL Digital Intercom Simply Communicate Advanced Digital Networking: Simple, Flexible, Cost-effective In today’s high-pressure production environments, intercoms must provide the timely and reliable communications that are critical for coordinating complex, fast-paced events. Whether at work in a theater, concert hall, performance centre, touring show, convention hall, or broadcast facility, the intercom supplies a vital information link that keeps activities flowing smoothly. The new ASL Digital Intercom system marks a breakthrough in providing efficient, reliable communications for demanding live production and event management applications. Thanks to innovative use of the newest networking technologies, the ASL Digital Intercom system looks elegantly simple at first glance. But don’t be misled by the remarkable ease of use. Alongside streamlined functionality, ASL Digital Intercom also offers elevated performance, enhanced flexibility, and user features never before seen in any intercom – analog or digital. Advanced Intercom Matrixing (AIM™), the core technology within all systems, helps make ASL Digital Intercoms remarkably easy to design and install. Once in operation, ASL’s intuitive ConfigurIT™ software makes it easy to configure the system for particular applications as well as to create multiple configuration presets for different event types or productions in rotation. event can be saved as presets to allow instant system reconfiguration for different productions in repertory. Flexible and expandable configuration ASL Digital Intercom networks can be configured using star, daisy-chain or line topologies. System designers can choose the approach that is most efficient and cost-effective for the given application. Each compact (1U) matrix unit serves up to 40 users (beltpacks or speaker stations), and up to six units may be linked via Cat-5, COAX or fiber optic cable (using the equivalent link module) to expand capacity up to 240 user stations. ■■ Intercom Hub ■■ Star Configuration ■■ Matrix ■■ Daisy Chain Configuration Matrix Wallbox Simplified setup and multi-event configuration Initial system setup is an efficient, streamlined process using proprietary ConfigurIT software. First, unique user IDs are assigned to a person (“Jack Jones”), a job title (“Lighting Director”), or a physical location (“Lighting Booth”). Each user is then assigned a station type: beltpack, 16-channel speaker station, 8-channel speaker station, etc. Users (and user stations) can be quickly assigned to user groups for different applications and productions. Assignments for each new 2 Wallbox Wallbox ■■ ■■ Wallbox Direct connections via voice or text ASL’s advanced implementation of networking technology enables several new user benefits. For example, ASL Digital allows direct person-to-person communication (like a telephone Line Configuration call) from any user station (including beltpacks) to any other user station, without tying up a channel. In addition, ASL Digital Intercom offers text messaging from a keypad speaker station to any other user. This can prove extremely valuable when an operator is temporarily away from his or her station, or cannot immediately respond to a voice call. Wallbox The ASL Digital Intercom builds on a solid foundation. After all, ASL is known worldwide as a leader in the design and engineering of high quality analog systems. In creating our new digital systems, a fundamental goal was to ensure – at a minimum – the same level of reliability and user utility available in our analog products. With this firmly in mind, ASL engineers then applied the latest advances in digital networking, while also creating new proprietary network protocols ideally matched to “fail-safe” intercom applications. The result is ASL Digital: a robust and exceptionally flexible intercom system offering a number of exclusive user benefits. Advantages at a Glance Matrix Wallbox Wallbox ■■ Wallbox Advanced Intercom Matrixing (AIM) Technology - The core technology in ASL Digital Intercom systems, AIM provides extraordinary configuration flexibility along with easy-to-understand user interfaces. Flexible network configuration – Accommodates in-line, daisy-chain or star topologies Expandable and scalable – From one matrix unit (40 user stations) to six matrix units (240 user stations) Digital audio throughout – No noise, exceptional voice clarity Conference communication – Up to 256 user groups possible Person-to-Person communication (PTP) – Any user station can talk directly to any other user station without tying up a channel Text messaging – Any keypad speaker station can send short text messages for display at user station of any other user ■■ ■■ ■■ ■■ ■■ ■■ The network recognizes each user station according to its assigned unique unit number. Simple, intuitive ConfigurIT software – A Linuxbased program, with no special training required. Binaural (split ear) headset option – Beltpacks and speaker stations can be ordered for use with binaural headphone Standard Cat-5 wiring – All connections between user stations employ standard Cat-5 cable, so any existing spare Cat-5 capacity can be utilized. (Note: ASL’s propriety network protocols will not function on an existing active LAN.) Auto-restore function – All current operational settings are maintained following power interruptions Advanced DS 290 beltpack receives text messages and features dual iN-touch “iPod-like” touch-sensitive, recessed ring volume controls. Straightforward, intuitive operation In the tradition of ASL analog systems, the ASL Digital Intercom system is exceptionally functional and easy to use. Signal lights are easy to recognize, and offer adjustable brightness. Controls are large and clearly labeled. New technologies are implemented, as with the unique iN-touch™ “iPod-like” touch-sensitive volume controls on the DS 290 Beltpack. In every respect, the ASL Digital Intercom controls and displays reflect thoughtful design as well as close consultation with long-time intercom users. 3 Core System Components DS 4000 M Master A single DS 4000 M Master Matrix is the centerpiece of a basic ASL Digital Intercom system for as many as 40 users. The user stations are connected via five Intercom Line output connectors on the rear panel. Connected cables may be configured as line, daisy-chain or star topologies. Each Intercom Line contains the data for a maximum of eight user stations. The Intercom Line output connectors also supply +48 VDC over the Cat-5 cable; this power is available to beltpacks and smaller speaker stations that do not have their own power supplies. An ASL Digital Intercom system can be expanded to as many as 240 users by linking up to six DS 4000 M or DS 4000 S matrix units, e.g. one DS 4000 M with five DS 4000 S units. Nearby matrix units (i.e. same rack) may be connected via optional high speed Cat-5 link modules; more distant units may be connected using the optional COAX or fiber optic link modules. Each 1U matrix unit also accommodates one or two additional interface modules. Interfaces include analog party line or 4-wire intercom, audio in/out, paging, IFB, telephone, and emergency announce. Two standard D-Sub connectors provide access to eight programmable GPIO connections (8 x in & 8 x out). A DS 4000 M Master Matrix supplies comprehensive facilities for external control, programming and offline storage of preset configurations. Front panel connectors are one RJ-45 (for temporary connection to a Mac or PC computer) and one USB (for flash drive, keyboard or mouse). Rear panel connections are VGA (for touchscreen monitor), two additional USB ports, and an Ethernet (RJ-45) for permanent networked control connection. 4 Advantages at a Glance ■■ One unit supports systems for up to 40 users ■■ Up to 240 users by linking six matrix units ■■ Five users strings (up to 8 users each) configurable as star, line or daisy-chain ■■ Front-panel USB and RJ-45 connectors ■■ Dual switch-mode power supplies for redundancy ■■ LED indicators for String On and Overload ■■ Rear panel Ethernet, VGA, USB (2) and GPIO (8) connections ■■ Optional Cat-5, COAX or fiber optic link modules ■■ 2 Interface slots (for interface modules) ■■ Available DS 4000 S Slave unit(s) DS 4000 S Slave The lower-cost DS 4000 S Slave is designed for use in conjunction with one or more DS 4000 M Master Matrix units. The DS 4000 S performs the same functions as the DS 4000 M in the intercom network; however, the front and rear USB, PC and Ethernet connections required for external control and programming functions are removed. DS 1640 16-channel Speaker Station The DS 1640 provides comprehensive and exceptionally flexible communication facilities for users at key command locations. Housed in a compact 1U frame, the DS 1640 enables instant TALK and LISTEN access to 16 separate user groups. With addition of the optional DS 2040 Extension Panel, this capability extends to 36 groups. Advantages at a Glance The DS 1640 may be tailored to specific user needs using the eight “soft” function keys. Selected functions are accessed in two layers (using the shift key), with current functions shown in the adjacent display. Functions available are CALL TO, CALL TO TALK, TALK TO ALL, SPEAKER ON/OFF, REMOTE TALK MUTE SEND, REMOTE TALK MUTE SEND PER GROUP, REMOTE SPEAKER MUTE SEND, REMOTE BUZZER MUTE SEND, BUZZER ON/OFF, STOP PTP RECEIVE, MIC DIRECT OUT (Stage Announce). ■■ A rotary knob serves as a volume control for the intercom signal in normal operation; when pushing and turning the volume knob it controls the PGM volume, and it serves as an encoder in programming mode. In conjunction with the keypad, the encoder enables selection of “soft key” functions as well as selection from among many other mode, status and parameter adjustments. The keypad also facilitates PTP communication (including a “speed dial” function) and sending of text messages. ■■ ■■ ■■ ■■ ■■ ■■ ■■ ■■ 16 separate TALK and LISTEN buttons SOLO button MIC ON button Person-to-Person (PTP) call button Eight programmable function buttons in two layers Adjustable button illumination Text messaging enabled GPIO connectors Two XLR-F connectors for program input plus one XLR-M for audio output (stage announce output) DS 2040 EP 20-channel Extension Panel In conjunction with a DS 1640 Speaker Station, a DS 2040 extends the user station access to as many as 36 discrete user groups. The TALK/LISTEN buttons and integral OLED displays are identical to the DS 1640. The DS 1640 rear panel incorporates D-Sub connectors (2) for 8 GPIO connections (4 x in and 4 x out each) ; D-Sub for Extension Panel; etherCON™ connectors (2) for Intercom IN and LINK ; XLR-F (2) for program input; XLR-M for audio output (stage announce output); and a ¼” jack for extension speaker. A small (1.5” x 2.5”) loudspeaker is integrated into the unit’s front panel. 5 5 Tabletop Speaker Stations ASL Digital Tabletop Speaker Stations provide comprehensive, flexible and user-friendly communications in a smartly styled, 3U angled surface-mount cabinet. The units are locally powered by a 48 V DC adaptor, supplied by ASL. With four different versions available, system designers can select units that fully serve all communication needs at each location. DS 830 Tabletop Speaker Station DS 1630 Tabletop Speaker Station The Tabletop Speaker Station line includes the DS 830 (8 channels), the DS 1630 (16 channels), the DS 2430 (24 channels) and the DS 3230 (32 channels). All Tabletop Speaker Stations include Wall mount strips. Key features on all Tabletop Speaker Stations include: ■■ ■■ ■■ ■■ ■■ ■■ ■■ ■■ ■■ ■■ ■■ ■■ Separate TALK and LISTEN buttons for each channel SOLO button MIC ON button Person-to-Person call button Eight programmable function buttons (“soft keys”) in two layers Adjustable button illumination Text messaging enabled GPIO connections (4 GPI & 4 GPO) Program input Integral loudspeaker (1.5” x 2.5”) External speaker jack 3U rack-mount kits available for each of the versions The selected functions are accessed on four buttons in two layers, using the Shift key to change layers. In normal operation, the rotary knob serves as local intercom volume control; pushing the knob while turning controls the PGM (program) volume. In programming mode, the knob serves as a rotary encoder. In conjunction with the keypad, the encoder selects the “soft key” functions and also enables selection of many other mode, status and parameter adjustments. The keypad also facilitates PTP communications (including a “speed dial” ) and the sending of text messages. DS 3230 Tabletop Speaker Station DS 2430 Tabletop Speaker Station “Soft Keys” and Other Programmable Parameters The following functions may be assigned to the programmable “soft keys”: ■■ ■■ ■■ ■■ ■■ ■■ ■■ ■■ ■■ ■■ ■■ 6 CALL TO CALL TO TALK TALK TO ALL SPEAKER ON/OFF REMOTE TALK MUTE REMOTE TALK MUTE PER GROUP REMOTE SPEAKER MUTE REMOTE BUZZER MUTE BUZZER MUTE OWN STATION PTP RECEIVE DISABLE MIC DIRECT OUT (STAGE ANNOUNCE) DS 830 with DS 830 Rack-mount Kit DS 1630 with DS 1630 Rack-mount Kit DS 2430 with DS 2430 Rack-mount Kit DS 3230 with DS 3230 Rack-mount Kit 7 Core System Components DS 290 2-channel Beltpack featuring iN-touch control Built to the same strict standards for ruggedness and reliability as ASL’s renowned analog beltpacks, the DS 290 offers all the features expected in any high-quality 2-channel unit: separate TALK, and CALL buttons, separate volume controls, MENU button, separate activity indicators, and a factory option for use with binaural headsets. In addition to these capabilities, the DS 290 applies advanced digital technology for a higher level of performance and unprecedented user utility. The DS 290’s ability to receive text messages can prove critical when essential information must be given before all users are at their stations, or when audible interruptions are not possible. Also, the Person-to-Person (PTP) call capability allows critical or unexpected point-to-point communications to go through without interrupting communications on a regular group channel. To adjust headset levels on the separate channels, the DS 290 uses dual iN-touch “iPod-like” volume controls instead of standard potentiometers. With no external or moving parts, the iN-touch controls eliminate frustrating problems with lost or broken knobs or “scratchy” potentiometers. In normal operating mode, the bright OLED display shows group names and Listen volumes as bars. When text messages are received, message content is displayed. Pressing the PTP button initiates a PTP call, and both the display and the TALK and CALL buttons switch over to PTP call mode. Pressing the MENU button puts display and buttons into MENU mode for selection and adjustment of options. The DS 290 connects to the intercom network via secure etherCON connectors (IN and LINK) on the bottom panel. An XLR-4 connector (XLR-5 when binaural) is provided for the headset, and a separate 2.5 mm micro jack allows connection of a “listen only” headset. 8 Advantages at a Glance ■■ Sleek, ultra-modern design ■■ Dual iN-touch “iPod-like” touchsensitive volume controls have no moving parts and no external knobs ■■ Separate CALL and TALK per channel ■■ Bright, high-contrast OLED display ■■ Person-to-Person (PTP) calling enabled ■■ Text message display ■■ Built-in mic limiter ConfigurIT software provides a simple, easy-touse graphical user interface (GUI) for configuring ASL Digital Intercom systems. It also allows users to quickly create various presets to automatically reconfigure the system for different types of events, or for different productions in repertory. ConfigurIT software is stored in non-volatile memory inside the DS 4000 M Master unit. The configuration is effective for both the master matrix and all connected slave matrix units. ConfigurIT software can be operated (and configurations created and edited) using a touchscreen; a standard screen with mouse only or mouse and keyboard; or a connected laptop computer. ConfigurIT software may be operated or edited ON LINE (in an active event) or OFF LINE. Event Configurations may be saved to a USB stick for later loading into other matrix units or as back up. ConfigurIT operation tasks are clearly and intuitively divided into several different screens, each corresponding to various steps in the configuration process: Naming the event, creating groups, creating users, naming the user IDs, assigning users to groups, groups to channels, and creating preset configurations for different productions or types of events. The Event Creation & Selection screen is used to create, save, add or delete events. An event is active when selected and the administrator chooses to “Activate This Event.” The Groups screen is used to create and name user groups. Check boxes allow the administrator to read/check functions of various users in the group. On the Users screen, the administrator may add users and also define station function properties. Groups may be assigned to available channels of a user station. The Users/Groups screen presents a graphical matrix wherein Group/ User assignments may be created or modified for the event. Other ConfigurIT screens provide specific detailed information – in clear graphical format – on Interfaces used for the event; the basic Network configuration; and underlying detailed information on the System software, equipment, and DSP engines. 9 9 Interfaces Accessories Several Interfaces are available that afford maximum flexibility in system configuration, and also maintain seamless compatibility with existing communication and auxiliary systems. ASL provides a complete array of intercom accessories, allowing system designers to customize each intercom configuration to match specific application requirements.
