SYSTEM DESCRIPTION
The JSD-60 cinema sound processor is specially designed for digital cinema applications. Low
noise and low distortion 96 kHz processing ensures superb presentations. In addition to the six
standard formats. A user-configurable format button can be configured to support a variety of
existing and future formats. It 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 JSD-60 is “automation friendly.” It features the standard DB25 parallel automation
interface, an RS-232 (EIA232) interface, and Ethernet. The Ethernet interface accepts five
simultaneous TCP connections to allow control by a digital cinema server and other equipment
while simultaneously being monitored over another TCP connection.
The graphical user interface (GUI) runs on Windows XP®, Windows 7®, Windows 8®, and
Windows 10® operating systems. It allows for complete system configuration, monitoring, and
firmware updates over USB, Ethernet, or RS-232. The 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 JSD-60 includes a precision 1/3 octave RTA that uses the filters specified in ANSI S1.11-
1986. The JSD-60 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.
The JSD-60 includes an automatic equalization feature (auto-EQ). 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 JSD-60 supports graphic and parametric equalization methods with bass management.
The 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).
