Lectrosonics Unveiling ASPEN (Audio Signal Processing Expansion Network) Series At 2009 InfoComm

At the 2009 InfoComm show in Orlando, Lectrosonics announces the introduction of the ASPEN (Audio Signal Processing Expansion Network) product line that employs sophisticated proprietary algorithms developed by Lectrosonics and the latest in high-speed DSP hardware.

The ASPEN Series also includes TCP/IP control over Ethernet, unlimited input expandability, real-time clock, 48-channel matrix bus, 1 Gbps expansion port, and true 48-Volt phantom powering for all inputs.

All ASPEN Series products are RoHS-compliant (Restriction of Hazardous Substances) and will include the SPN812, SPN1612, SPN1624, and SPN2412 matrix processors, the SPNConference unit for teleconferencing, the SPNTrio all-in-one teleconferencing processor with power amp, the SPN16i and SPN32i input-only modules, and the SPNPower12 multi-channel power amplifier.

All units employ the ASPEN port with 1 Gbps throughput capability for audio and control data on a single CAT-6 line.

At the heart of the ASPEN system is Lectrosonics’ proprietary Proportional Gain Algorithm (PGA) for auto-mixing without the use of noise gates, resulting in transparent audio and increased gain before feedback. Five mixing modes are individually selectable for every matrix cross point.

Centralized echo cancellation enables bridging for Telepresence applications along with simultaneous TELCO and videoconferencing. Near-side latency is kept to 1.33 ms for a single unit, with only 0.125 ms for each additional unit in the system. 48 mixes on each board facilitate output matrixing up to 48 channels.

Every input in the ASPEN system supports mic- or line-level signals and includes a 1/3-octave noise reduction filter, an 8-notch feedback suppressor, delay, a 4-band 4th-order filter set, a dynamic compressor, and two level meters. 48V phantom power is available on all inputs—allowing for the widest possible compatibility with all microphone types.

Every output includes an eight-stage, 4th-order filter set, delay, dynamic compressor, limiter, and level meter. All inputs and outputs are fully differential.

Programming and access of ASPEN devices is handled via a single, centralized point of control through Ethernet, USB, or RS-232. The system also allows for simultaneous multi-point third-party (Crestron and AMX) and native control.

Karl Winkler, Lectrosonics’ Director of Business Development, states, “Encompassing matrix processors, teleconferencing units, the capacity for input expansion, integrated power, Phantom powering for microphones, plus flexible system control options, the ASPEN product line brings an entirely new level of feature-rich versatility to a wide range of conferencing applications.

“With the ability to be customized to their environment, these systems are ideal in presentation spaces, meeting facilities, boardrooms, houses of worship, and similar venues where the ability to automate and control a variety of input/output sources without supervision of an AV technician is highly desirable. I’m confident those who design and install AV systems will find much to like.”

Pricing and availability of the new ASPEN Series product line has not yet been finalized.
