SSP 200

The Extron SSP 7.1 five input Surround Sound Processor provides up to eight channels of surround sound for pro AV applications in corporate and commercial environments. The SSP 7.1 automatically detects and decodes audio content in various Dolby® and DTS® formats from DVD, Blu-ray Disc, and HDTV broadcasts. It also offers Dolby Pro Logic II/IIx and DTS Neo:6® processing to provide surround sound from two-channel stereo. The SSP 7.1 features coaxial and optical digital inputs, plus an analog balanced/unbalanced two-channel input. It is designed for integration into pro AV installations, with a compact, rack-mountable metal enclosure, RS-232 serial control, and balanced/unbalanced line level outputs. The included control software offers a user-friendly GUI for setup and operation.

The SSP 7.1 is designed for simple, intuitive operation from the front panel, with LED indicators for source selection, source format detection, listening mode override, and output volume level. At the touch of a button, the user can override the current surround sound output and switch to a different listening mode, for example, from 5.1 channel Dolby Digital to two-channel downmixed stereo, or from two-channel stereo to 7.1 channels via Dolby Pro Logic IIx. The user also has the option to send stereo audio to all left and right speakers without surround sound processing.

Control and Configuration

The SSP Setup and Control Software features an intuitive user interface for efficient setup and control of the SSP 7.1 as well as calibration of the sound system. Using the software, an integrator can specify the number and size of all speakers in the system, and enter the distance of each speaker from the central listening position, or location where acoustical measurements are taken. A nine-band parametric EQ is available for each of the satellite speaker channels to tailor the output signal to the acoustical environment.

Test Signals for Calibration

The SSP 7.1 generates test signals including Dolby noise and full-bandwidth pink noise that can be routed sequentially to each speaker, or directed selectively to any speaker using the software. Dolby noise is a band-limited pink noise that allows for higher sound pressure levels, which is advantageous when calibrating speaker outputs to equal SPLs. An individual trim level is provided for each channel to facilitate calibration. The pink noise test signals can be used to calibrate a speaker’s interaction with the acoustical environment. The SSP 7.1 also offers the option to use an external source for test signals, which can then be directed to any speaker, or all speakers in sequence.

Designed for Pro AV Integration

The SSP 7.1 is housed in a 1U, half rack width enclosure that is rack-mountable and occupies a fraction of the space required for a conventional surround sound receiver. It can be controlled and configured using RS-232 serial control. For compatibility with pro AV sound equipment, the SSP 7.1 offers balanced or unbalanced inputs and outputs. Front panel controls can be locked out to prevent unauthorized operation.
