Chapter 1 Intr oduction The DSA250i full-range and DSA230i voice-only or low frequency system are small format, column-type loudspeaker systems with a user-variable vertical beamwidth. The loudspeakers, known as modules herein, can be used as singly or combined in multiples as clusters.
2.3 Returning Products to EA W If the loudspeaker must be returned to EA W , contact the EA W Service Department for a Return Authorization (See Chapter 7). Use the original shipping carton and packing materials. If the shipping carton is lost or damaged, contact EA W for a new carton, for which there will be a small charge.
3.3 Computer Control Connection NOTE: Set the EIA-485 T erminate Switch to “ON”. For multiple modules, see Chapter 5. EIA-485: 2-conductor shielded audio cable/supplied Phoenix Contact terminal block plug 3.4 Daisy Chaining A udio and Computer Signal Between Modules Distances up to 2 ft / 0.
3.6 Ph ysical Installation 3.6.1 ORIENT A TION 1. When installing the enclosure, there is a correct “top” and “bottom”. This cannot be assumed from the physical appearance. Instead, orientation depends on application and desired acoustical performance determined using DSAPilot.
3.7 Signal Processing The vertical coverage is determined by programming the module’ s digital signal processing. Use DSAPilot to determine the desired coverage. DSAPilot calculates and optimizes the signal processing required to achieve the desired results.
4.1.2 A COUSTICAL BENEFITS Each module can be electronically adjusted on-site to direct sound primarily where needed. Unwanted sound reflections from room surfaces can be reduced, improving the direct to reverberant sound ratio. This, in turn, can significantly increase speech intelligibility .
· Full frequency response and high output for music applications. · Extended pattern control and higher outputs at lower frequencies using additional DSA230is. · Exceptional intelligibility for reverberant rooms. 4.2.2 ELECTRONIC · Self-powered requiring wiring for ac power , line level audio, and computer control.
4.3 Applications The DSAi Series provides a significant advance for cost-effective implementation of line array technology in a variety of applications. As is typical for line arrays, the DSAi Series is an excellent choice for voice- only applications.
Multiple DSAi modules arrayed as a cluster at a single location allows a greater range of beamwidths, SPL, pattern control, and low frequency output than a single DSAi module can provide. DSAPilot treats the cluster as if it were a single loudspeaker , precluding the complexities normally associated with designing and tuning clusters.
4.5 DSAPilot DSAPilot, used to set the module signal processing parameters, is based on software originally developed by EA W engineers for the KF750, KF760, and, in particular , the KF900 Series products.
Chapter 5 Installation This chapter details the requirements for installation. Specific details may require some variation depending on the particular situation. However , the basic requirements are the same in all cases. Module refers to either a DSA230i or DSA250i.
5.1.2 A UDIO SIGNAL CONNECTION See Appendix 8.6 for details about multiple module wiring configurations. CobraNet: Skip to Section 5.2 if using CobraNet for distribution of the audio and control signals.
2. Up to 2 ft / 0.6 m between adjacent side-by-side modules in a cluster User-supplied Cat-5 crossover cable. Connect between unused Signal Link jacks (Neutrik EtherCon) on horizontally adjacent ends of the modules.
5.2 CobraNet™ A udio and Computer Control See Appendix 8.6 for details about multiple module wiring configurations. This section provides details about using the optional CobraNet technology for distribution of audio and computer control signals. 5.
5.2.4 CABLING A CA T -5 or better cable with RJ-45-compatible connectors is required for each module. NOTE: Ethernet cable length is limited by specification to 328 ft / 100 m. Longer runs are possible using network hubs or switches as repeaters or by conversion to fiber optic cable.
5.3 Fault Detect - Supervisory Monitoring This section details how to remotely monitor the operating status of a DSAi module. This is done by connecting a monitoring circuit, better known in the trade as a supervisory circuit, to the F AUL T DETECT Form C relay integral to each DSAi module.
5.3.3 SUPER VISOR Y CIRCUITS While there are a number of possible supervisory circuits, the normal method is to use the relay contacts to connect or disconnect power to an annunciator . This can be a light, audible alarm, computer interface, or other indicator .
5.4 A C Mains P ower Connection This section details the requirements for the ac mains which is the ac power connection required by each DSAi module. 5.4.1 A C MAINS SUPPL Y W ARNING: Read W ARNING under SAFETY INSTRUCTIONS on Page 2. Each DSAi Series module is rated for a particular nominal ac mains voltage: 1 15 V or 230 V .
If it is desired to completely power off (de-ener gize) the module, a conveniently located ac mains disconnect must be supplied or the power cable must be unplugged from the module or the ac mains supply . The PowerCon connector is a locking connecter .
5.6 Physical Installation This section details the physical requirements and methods for installing the module. Specific mounting procedures detailed herein may require some variation depending on the particular situation. However , the basic methodology is the same in all cases.
The orientations are shown in the DSAPilot graphics. When activated by the DSAPilot software, this LED can be used to verify both the correct up-down orientation and, when multiple modules are used, the correct location of each. For the DSA250i, the Power End is the end with the HF subsystem and Signal End is the end with the LF subsystem.
5.6.4 INST ALLA TION OPTIONS Normal Method: This method is for installing DSAi modules flush-mounted to a vertical wall surface using the supplied brackets. The installation instructions herein apply to this installation method. Optional Normal Method: This method is for suspending DSA modules.
5.6.6 MOUNTING HEIGHT The elevation entered into DSAPilot refers to distance from the bottom of the module’ s enclosure or the bottom of the lowest module’ s enclosure in a multi-module cluster to the floor below . Thus, the mounting height is the same as the elevation in DSAPilot.
4. Provide attachment hardware and secure the supplied W all Brackets to the mounting structure, complying with all Danger and Caution notes in Section 5.
2. Install at least one of the supplied 1/4-20 X 3 in Retainer Bolts with its lock washer through the side of either the top or bottom W all/Enclosure Bracket and snugly tighten.
Chapter 6 Operation This section provides details about DSAi operation. The general operation of a DSAi module is similar to the operation of most loudspeakers. Initial system set-up and overall tuning adjustments detailed in this Chapter must be made using DSAPilot.
NOTE: This is likely an unusual condition because the LED will respond only if the input signal levels are greater than +24dBu. It is recommended that this function normally be disabled. 3. Output Compressor/Limiter Active: If this indication is enabled, random flashing shows that the amplifier output compressor/limiters have been activated.
6.2 Operational Check List T o operate a DSAi module, pre-performances checks and adjustments should be made. In typical permanently installed applications, these checks would normally be one-time, set-up adjustments that may only need to be periodically verified.
6.4 Operational ‘DOS’ and ‘DONT'S’ 6.4.1 EQU ALIZA TION If equalization is required for tailoring the frequency response during performances, use an external equalizer such as a good quality 1/3 octave graphic equalizer , for this purpose.
Chapter 7 Maintenance and Service This chapter provides information about warranty coverage and service. 7.1 W arranty See the supplied warranty card for warranty details. 7.2 Service Items There are no field serviceable parts for the DSA250i or DSA230i.
Chapter 8 Appendices 8.1 Inspections and Maintenance 8.1.1 PERIODIC PHYSICAL INSPECTIONS Complete and thorough inspections should be done on a routine, periodic basis. The interval between inspections and scope of the inspections will depend on the conditions of use.
34 8.2 T roubleshooting This troubleshooting table addresses some common faults. For other difficulties not listed, contact the EA W Service Department. SYMPTOM POSSIBLE CAUSE SOLUTION DSA250i Only: No HF output Failed internal component Module needs service.
Coverage is incorrect Improper set-up Using DSAPilot, ensure the desired beamwidth and aiming angle are correct. Coverage is incorrect Module upside down Using DSAPilot to active the module’ s LED indicator , ensure the up/down enclosure orientation is correct for the application.
CobraNet Audio signal or computer Network cabling does Ensure Ethernet cabling meets communication not functioning not meet specification IEEE 802.3u specifications for or not functioning correctly 100BASE-T networking.
8. DO NOT connect modules or clusters in a “stub” fashion. This means do not connect a branch cable off an EIA-485 cable to run to a module or cluster . 9. DO NOT connect the far end of the EIA-485 cable back to the computer . This means do not make an electrically closed loop for the EIA-485 cabling.
8.6 DSAi CONNECTIONS This appendix discusses the operation of the DSA's communications system, some additional connection configurations, and why things go wrong if not connected properly . 8.6.1 BA CKGROUND Phoenix Audio Connectors: The two balanced Phoenix audio connectors are for standard, line level, analog audio signals.
8.6.3 EIA-485 Figure 8.6.3a is the simplest setup with an EIA-485 bus connection to DSAi module "A" and with a Link Ports connection to DSAi module "B".
8.6.5 PROPER DSAI INST ALLA TIONS Here are some examples of DSAi installations that will work reliably , both avoiding loops and keeping EIA- 485 running well.
EXAMPLE 3: Should you be working with a CobraNet Audio source that does not support the serial bridge feature, you can follow this next connection scheme.
EXAMPLE 1: (no figure shown) One cabling configuration that you should NEVER make is to daisy-chain the EIA-485 cabling from module to module then home run a cable from the last module back to the PC to create a closed loop.
EXAMPLE 4: Looping occurs between both the Link and CobraNet connections. 8.6.7 A V OIDING STUBS AND CORRECT 120 OHM TERMINA TION A long stub or branch off of an EIA-485 bus can cause a significant impedance mismatch and thus reflections and degradation of the computer control signals.
