Lectrosonics, recognized the world over as a leading manufacturer of wireless microphone systems and audio processing products, is introducing two new processors for the Aspen product line: the SPN Conference Wideband and the SPN Trio Wideband. Both units feature the newly developed AEC (Acoustic Echo Cancellation) algorithm with wideband audio response to 20 kHz. This new algorithm was developed to address the needs for a single acoustic echo canceller to handle the challenges of multi-site bridging and an unlimited number of microphones on the system.
The 1RU SPNCWB wideband conference interface makes telepresence and multi-site bridging simple and effective in any conference room, with full bandwidth audio frequency response and a unique Quad-reference AEC. Each conference connection includes a dedicated AEC for fast and reliable echo cancellation including telephone line (POTS) and two Codec inputs. The fourth AEC is assignable to any final mix in the matrix for purposes such as noise cancellation (when fed a signal from a sampling microphone). The SPNCWB also features two power amp outputs for in-room loudspeakers.
The SPNTWB Trio wideband unit combines the boards from the SPN812 auto matrix mixer and the SPNCWB conference unit in a 2RU chassis to provide a complete, stand-alone component for telepresence and audio conference systems. The SPNTWB also incorporates a large graphic LCD on the front panel for setup and monitoring. Inputs and outputs appearing on the LCD have been consolidated into logical groups to simplify navigation. Like the conference unit, the Trio Wideband has two power amp channels for local loudspeakers.
Both units can be used with additional Aspen processors to add additional inputs and outputs for larger systems. An Ethernet port is provided on all Aspen processors for setup and control via standard network connections, and an RS-232 port is provided for use with remote control systems. The innovative design allows simultaneous, multi-point third party control.
MSRP for the SPNCWB is $3,250 while MSRP for the SPNTWB is $5,900. Both units will be available in the third quarter of 2013.
