The JSD-60 holds a log of the last 15,000 events. Events include level changes, format changes, remote connections

by the GUI or other devices, etc. Press the Get Latest button to get the 100 most recent log entries. Press the Get

All button to get the full log from the JSD-60.

The log shows the record number in the JSD-60 log, the UTC time of the event, the “JSD Time” of the event, and

the “GUI Time” of the event. The JSD-60 stores all log events in UTC time. When the log events are displayed by

the GUI, the time at the JSD-60 is calculated based on the settings entered using the “Date & Time” button on the

Global Tab. The GUI applies the time zone offset for where the JSD-60 is located, determines if the daylight saving

time is observed where the JSD-60 is located, and whether daylight saving time is currently in effect. Based on this

data, the GUI calculates and displays the time of the event at the JSD-60. The name of the time zone (PDT in the

sample) is shown in the column header to help identify the time. The GUI also does a similar calculation to display

“GUI time” or local time for the computer running the GUI application. That is the time the event occurred at the

GUI location, which may be several time zones away from where the JSD-60 is located. The log shows the source of

the event (internal, USB Port, front panel, TCP4, etc.). When a device connects to the JSD-60 over Ethernet, the

connection and the IP address are logged. Later actions can be tied to a specific IP address by looking back

through the log for the last connection to that TCP port. The JSD-60 supports 5 simultaneous TCP connections on

TCP4 through TCP0.

Pressing the Save button saves the currently displayed log data as a tab delimited text file. This file can be

imported into a spreadsheet or viewed with a text editor.

7.10.9 Diagnostics Tab

This tab provides diagnostics that help USL personnel in debugging the system. You may be instructed by USL to

perform various functions on this tab to debug problems in the installation. The terminal section of this screen can

be used to test JSD-60 commands, such as ones an automation system can send. Click the mouse cursor in the

terminal area, and then type commands (tab delimited and terminated with a carriage return). See Appendix B for

more information on automation commands.

7.11 Channel Crossover and Equalization Procedure

Audio channel equalization consists of two steps:

1. Crossover adjustment (if crossovers used).

2. Channel Equalization.

7.11.1 Crossover Adjustment

A suggested crossover adjustment procedure is listed below. It should be skipped if the JSD-60 internal crossovers

are not being used. If an external pink noise generator is to be used with the internal RTA, enable the internal pink
