EASE v4.2

EASE v4.2 is an acoustic simulation software program designed for the Windows operating system that provides sound system designers an invaluable tool for predicting the performance of a sound system in a given venue. The software program is primarily geared toward large-room acoustics (churches, stadiums, arenas, theaters, etc.) and with additions to v4.2 offers valuable tools for smaller environments such as Privacy indexes for office spaces, etc.

It includes numerous acoustical design and analysis tools for Contractors,

Engineers and Acoustical Consultants, and with the new Vision module offers greatly

improved visual rendering capabilities with the ability to add light sources and import surfaces, making it very desirable for the Architectural world. All features of EASE 4.2 are available as a block, or as partial options. As before, licensing is effected by means of a License Key; however, contrary to the procedure known from version 4.0, this can be obtained directly via the Internet immediately after installation of the program. Program updates can be downloaded directly from the Internet, as well.

Special features of EASE 4.2 for Windows:

•Enhanced user-friendly windows for menus and working surfaces allow direct access to the various program modules and program parameters

•Ample Speaker Data format of 5 Degrees and 1⁄3-Octave resolution, higher resolutions of up to 1 Degree and 1⁄24-Octave bandwidth can be stored in DLLs and used for calculations

•Introduction of complex Speaker Data including magnitude and phase, direct reading of measured impulse responses in all common measuring-file formats (TEF20, MLSSA,WAVE, MF)

•Provision of Speaker-DLLs for Line-Arrays

•Cluster calculation modules for speaker assemblies for far-field applications, DLLs for near-field and far-field calculations

•Data format of wall materials expanded to include diffusion coefficient

•Improved and simplified entering of room data, no limitation of model components, newly developed DXF import from AutoCAD 3D volume models, and entering of textures

•Simplified Room Modeling thanks to new Tools like expanded Extrude function and Object definition for partial models

•Room Visualization by high-definition rendering technique and with textures

•New Hide Option as 3D Rendering by means of lighting appliances

•New room-acoustical calculating module AURA based on CAESAR (University of Aachen) offers new and expanded tools and indexes not available in v3.0

•2D and 3D Mapping of all room-acoustical measures according to ISO 3382 with due application of the expanded Wall Material data base (absorption and diffusion)

•New Ray-Tracing options in AURA, like Echogram and AURA-Response

•Better visualization of impulse response computations

•New Predicted Tail computation for obtaining a complete impulse response

•Expanded features of off-line and online (real time) Auralization in EARS

•Real time auralization remains possible without additional hardware and in dual channel operation

•Storage capacity limited only by the actual hardware layout

•EASE Speaker Lab module with GLL device creation for array and cluster modeling, allowing more accurate virtual importing into base.

•All versions can be purchased with 2 licenses (full versions include 5 seats) for reduced cost.

EASE 4.2 for Windows is totally co m p atible with EASE 3.0 and is capable of reading all EASE loud- s pe a ker and pro j e ct data files and of converting them into the new format . Cu rre nt EASE 3.0 users will be able to upg rade to version 4.2 for a nominal

upg rade charg e. A Pentium-III-Processor with 1000 Hz or more is re commended as a minimum not only for meeting the requirements of aura l i s a- t i o n . EASE is supplied on CD-ROM and requires at least 128 MB of RAM plus 150 MB of available hard disk space (without database,which requires 100 MB additionally).

L i keVersion 4.0, EASE 4.2 is a 32-bit program capable of functioning with the ope rating systems Wi n d ows 98/NT/2000/XP.Windows 95 can no longer be recommended,s i n ce it requires special adjustments and Se rv i ce Packages.All feat u res of EASE 4.0 we re included in the new version.

Studio Monitors specifications

JBM electronic Studio Monitors have carved a niche for themselves in the competitive audio monitoring market, especially favored by musicians, producers, and sound engineers. These monitors are engineered to deliver accurate sound reproduction, ensuring that audio professionals can trust the source material they are working with.

One of the main features of JBM Studio Monitors is their impressive frequency response. They typically cover a wide range, often extending from 40 Hz to 20 kHz. This broad spectrum allows for a comprehensive listening experience, revealing nuances in recordings that might be missed with less accurate speakers. Additionally, many models incorporate advanced bass reflex designs, enhancing low-frequency performance without distortion.

The build quality of JBM monitors is another standout characteristic. Constructed from high-density MDF, they minimize resonance and provide a cleaner sound. The enclosure design works in tandem with the speaker's drivers to deliver clarity across different sound levels. The use of professionally tuned port systems ensures that low-end frequencies are reinforced, resulting in a punchy yet balanced bass response.

In terms of technology, JBM Studio Monitors often employ Class A/B amplifiers, which combine the strengths of both Class A and Class B to deliver power and efficiency. This amplification approach is integral to achieving minimal distortion, allowing for precise audio playback. Some models feature bi-amped designs, using separate amplifiers for the woofer and tweeter, further enhancing the monitors' fidelity and dynamic range.

Another notable feature in JBM electronic Studio Monitors is their room adjustment controls. Many units come equipped with equalization settings that allow users to tailor the sound profile to their specific environment, compensating for room acoustics and ensuring optimal playback. This adaptability is crucial in a professional setting where space can vary greatly.

Connectivity options are abundant, often including TRS, XLR, and RCA inputs, making these monitors versatile and compatible with various audio interfaces and mixers. The user-friendly design extends to ease of placement, with some models compact enough to fit in smaller studio setups while still delivering powerful sound.

In summary, JBM electronic Studio Monitors are designed to offer unrivaled sound accuracy and flexibility for audio professionals. With features like a wide frequency range, robust build quality, advanced amplification technology, and useful room tuning options, these monitors stand out as a worthy investment for anyone serious about sound production. Their reputation for reliability and performance makes them a popular choice among those in the audio industry.
