Lectrosonics has added two processors to its 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 20kHz. 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 1U-high SPNCWB wideband conference interface offers telepresence and multi-site bridging, with full bandwidth audio and a Quad-reference AEC. Each conference connection includes a dedicated AEC for 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 amplifier 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 2U-high chassis to provide a stand-alone telepresence and audio conference system. The SPNTWB also incorporates a large LCD on the front panel for set-up 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 amplifier 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 RS232 port is provided for use with remote control systems. The design allows simultaneous, multi-point third-party control.

The MSRP for the SPNCWB is US$3,250, while the SPNTWB is US$5,900. Both units will be available in Q3 2013.
