The USL JSD-60 cinema sound processor is designed for digital cinema applications. Low noise and low distortion 96 kHz processing ensures superb performance. In addition to the six standard formats user-configurable format buttons can support a variety of existing and future formats. They may also be used to duplicate an existing format but at a different fader level to simplify desired volume changes between content types. The front panel display shows the current fader level, the format name (which is user configurable), and the audio level on each audio output. The built-in bypass audio circuitry ensures that the presentation goes on in the unlikely event of a system failure.

The USL JSD-60 is “automation friendly”. It features the standard DB25 parallel automation interface, an RS-232 (EIA232) interface, and Ethernet. The Ethernet interface accepts 5 simultaneous TCP connections to allow control by a digital cinema server and other equipment while simultaneously being monitored over another TCP connection.

The USL JSD-60 graphical user interface simplifies installation by including sound pressure level measurement and automatic equalization. System monitoring, control, and firmware update functions are also available on a standard web browser.

The USL JSD-60 includes a precision 1/3 octave RTA that uses the filters specified in ANSI S1.11-1986. It also does sound pressure measurements using the C-weighted filter specified in ANSI S1.4- 1983. The RTA and SPL meter can be used to equalize an auditorium manually or automatically. An automatic equalization feature (auto-EQ) uses user-defined microphone calibration files and standard or user-defined equalization curves to automatically adjust the graphic equalizer on each channel.

The USL JSD-60 is also “diagnostic friendly.” The system logs the last 15,000 events (format changes, level changes, internal temperature, loss of AES/EBU audio, etc.) to internal flash memory. Log data can be reviewed on the GUI or the web interface. Current operational status, including selected format, fader level, and measured audio output levels, is available on the GUI and on the web interface. The current status of the system is also available over SNMP (Simple Network Management Protocol). An optional plug-in module decodes Dolby Digital and DTS encoded content. An optional crossover card supports the bi-amp operation of three screen channels and provides two LFE outputs.

The USL JSD-60 is available with a variety of processing and output options. Processing options include with or without Dolby Digital and DTS decoding. Output options include standard 8-channel analog, 8-channel analog with bi-amp for 3 screen channels, AES/EBU, and BLU link. All units have analog HI/VI-N.
