FRONT PANEL
The input select buttons choose which input is to drive the auditorium speakers. The LED above
the button will light when that input is selected. If the selected input is digital, but no digital
signal is available, the LED will flash. Pressing the “mute” button controls muting of the
auditorium speakers. The LED above the button is lit when the system is muted.
The display shows the current main fader level, the user defined name of the currently selected
format, and a bar graph showing the audio levels on each output. The number of bars and the
labels under the bars varies with speaker configuration. When the speaker configuration
includes use of the JSD-‐60 internal crossovers, the bar graph shows the low band in yellow, and
the high band in blue. Full range outputs (such as the surround channels, HI, VI-‐N) are shown in
green.
The Main Fader adjusts the output volume. As it is adjusted, the display is updated to show the
new fader level. Note that the fader level will generally change on a format change.
The main power switch turns the JSD-‐60 on and off. When the power is off, the JSD-‐60 enters
bypass mode if the bypass power supply is plugged in. The bypass system in the JSD-‐60 uses
completely separate electronics to generate a monaural signal that drives the left and right
main audio outputs. The front panel switches and fader operate the same in bypass and
normal modes. All inputs except microphone are available in bypass mode.

AUTOMATION
The JSD-‐60 accepts external control (such as automation) over Ethernet, RS-‐232, and a parallel
automation port.
•
The JSD-‐60 accepts up to 5 simultaneous TCP connections on port 10001. A digital cinema
server can send commands to the JSD-‐60 through a TCP connection. The command
structure is described in Appendix B.
•
The JSD-‐60 accepts commands over the RS-‐232 port. The hardware interface is described in
the installation section. The commands are described in Appendix B.
•
The JSD-‐60 accepts parallel automation pulses on the DB25F rear panel automation
connector. Pulsing pin 1 to ground is the same as pushing the first button on the front panel
(COAX 1). Pulsing pin 2 to ground is the same as pushing the second button. The parallel
automation interface is described in more detail in Section 7.9.

SYSTEM MONITORING
A large number of JSD-‐60 systems can be monitored simultaneously over Ethernet. Multiple
units can be monitored and controlled using the GUI. Multiple units can be monitored and
controlled using a web browser as well. The web interface duplicates the front panel controls,
