Publish date:

Lectrosonics has announced the company’s ASPEN Series of DSP matrix audio processors is expanding and that select models are now shipping. Employing sophisticated proprietary algorithms developed by Lectrosonics and the latest in high-speed DSP hardware, the new ASPEN Series features include 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.
New ASPEN Series products to be unveiled during this year’s InfoComm trade show—held from June 5-11 (exhibits, June 9-11)—in Las Vegas, NV will include the SPN2412, SPN1612, and SPN812 matrix processors, as well as the SPNTrio teleconferencing processor. All units are RoHS-compliant (Restriction of Hazardous Substances) and employ the ASPEN port with 1 Gbps throughput capability for audio and control data on a single Cat-6 line.

Lectrosonics’ SPNTrio combines a matrix mixer with a telephone hybrid and a 2-channel power amp for an all-in-one conferencing solution. With 2 CODEC and 1 line input, eight mic/line inputs, eight line outputs, and four mic/line outputs, the SPNTrio offers a wide range of connection possibilities. The 1 Gbps ASPEN port facilitates unlimited input expansion, should one’s requirements grow over time. Control via Ethernet, RS232, or programmable inputs makes designing around the Trio a snap.

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.

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—enabling 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.
