Network Time Protocol
This section also allows the IP address of the Network Time Protocol server to be set and enabled or disabled. If an
NTP server is available on the network, enter its IP address, check NTP Enable, and press the Set IP button.
SNMP Community Settings
This section allows the Write and Read community settings to be viewed or changed. The JSD-60 does not
currently use the write community setting since the JSD-60 cannot be controlled over SNMP, only monitored. The
contact, system description, and location information reported over SNMP can also be set. Read and Write
community strings are limited to 8 characters each. Contact, description, and location are limited to 39 characters
each.
Unit Status
This portion of the global tab shows the temperature within the JSD-60, whether the optional DI-84 board is
present, and the status of AES/EBU inputs. The DI-84 board is required to decode Dolby Digital® and DTS® from
two channel inputs. AES/EBU status is read every two to three seconds, and the status indicators are updated.
Green indicates the parameter is true. Red indicates it is false. Gray indicates it cannot be determined. As noted
AES 4 may indicate a red status when a digital two-channel or encoded multichannel (COAX and TOSLINK) source is
idle and not streaming audio data. When the audio is present, the sampling rate is indicated next to the decode
status results.
Power On Format
These buttons determine which format will be selected the next time the JSD-60 is powered up. The power on
format can be a specific format or can be the format that was active when the JSD-60 was powered off.
8.10.6 Advanced Tab
Analog and digital inputs to the JSD-60 need to be routed to the appropriate outputs based on the selected format,
the auditorium speaker configuration (channel config), and stereo decode options. This is often done with a switch
matrix, but the JSD-60 uses a mixer matrix. The mixer matrix allows inputs to be routed to outputs or combinations
of inputs to be scaled and routed to outputs. The scaling factors (mixer coefficients) may range from -100% to +
100%. A mixer coefficient is set to 100% to route the input to the output at full level. It is set to 0% to not use that
particular input on the output. It is set to -100% to route the input to the output with the phase reversed. Inputs
can be combined in various ratios to synthesize an output. For example, left and center can be combined to
generate Lc. Left, center, and right are combined to generate HI. When using the simple matrix decode option, to
generate surrounds from a stereo source, left and right are combined with opposite phase to generate the
surround channel.
Changing the channel configuration, input source, or stereo decode method source will reload the mixer
coefficients. You can modify these to create a custom format, but do not change the channel configuration, input
source, or stereo decode method after changing the mixer configuration. Otherwise your changes will be
overwritten with the default coefficient values.
