permits. Mounting the unit immediately above a major heat-producing component, such as a power amplifier, is
not recommended. Equipment mounted immediately above the JSD-100 should not be more than 9 inches
(225mm) deep to Ensure adequate airflow through the rear ventilation slots on the JSD-100. The JSD-100 includes
a three-prong grounding plug and a three-wire power cord to accommodate a safe ground path from the chassis to
the electrical system ground. Defeating this ground by removing the ground prong is not recommended.
6.3 Eight Channel Analog Output Rear Panel Connections
A set of clip-on ferrite “beads” is supplied with the JSD-100. To Ensure the JSD-100 continues to meet FCC and CE
radio emissions requirements, one of these beads should be clipped around each cable connected to the rear
panel of the JSD-100 except for the TOSLINK, AC Power, and Bypass Power connection.
1. Bypass Power Supply – 12VDC at 1.25A.
2. Power entry Module – Accepts IEC-type line cord from 100-240VAC power source. Also contains a 500mA Slo-
Blo 5x20mm fuse.
3. Eight Channel Analog Output Module – Other modules include 16 channel analog and 32 channel AES.
a. 8 Channel Analog Module provides six fixed outputs (L, C, R, LFE, Ls, Rs) and two that can be set up as
either Lc/Rc or Lrs/Rrs. Balanced line Phoenix and DB25M connectors are provided. The Phoenix
connector normally drives auditorium amplifiers and the DB25M connector normally drives a booth
monitor.
b. USL Link - An RJ25 connector that provides an RS-485 interface for remote volume control and other
functions.
4. Ethernet – Network communications with GUI, web browsers, automation, etc.
5. RS-232 on a DE9F connector for communications with GUI or automation.
6. Automation DB25F Connector – A bidirectional port for receiving and sending automation pulses between the
JSD-100 and other system components. 12 Control lines, 11 Status lines and +5V are provided. Standard pulse
to ground system.
7. SD Card – Stores a backup copy of unit configuration. Can also be used to transfer settings to another unit.
8. AES connector (DB25F) – Channels 1-8 are standard. Channels 9-16 require the optional DI-80 module.
9. AES connectors (Dual RJ45s) – parallel connections to the DB25F above.
10. TOSLINK Port – Optical Fiber input for SPDIF (PCM) or optional Dolby Digital®
2 decoding.
11. COAX 1, COAX 2 - RCA type connectors for SPDIF (PCM) or optional Dolby Digital® decoding.
12. Hearing Impaired/Visual Narration Outputs.
13. AUX connectors – L and R analog inputs, 300mV sensitivity.
14. Non Sync (N/S) connectors – L and R analog inputs.
15. RTA microphone – 3.5mm stereo jack with +10V on the ring, designed for use with a powered electret
microphone.
