6.2 Back Panel Input
Connections
Projector Inputs
The projector inputs are connected through
standard 9-pin D-type connectors. (These
connectors are included with the JSD-80).
The pinout is:
1. In L+
2. In L-
3. Shield
4. In R+
5. In R-
6. Gnd
7. Reserved
8. Reserved
9. Gnd
(An adapter board with setscrew terminals
is available for solderless connections.)
Non-Sync Inputs - Analog
Two RCA connectors facilitate easy con-
nection to standard CD players. A software
fade in/fade out algorithm allows smooth
transition between intermission music and
the main program.
Auxiliary Input - Analog
Two RCA connectors are used to connect
to external two-channel sources such as a
sound card in a computer supplying video
advertising content.
Microphone Input
The public address balanced microphone
input is available on a standard 9-pin D-type
connector.
The pinout is:
1. Mic in +
2. Mic in -
3. Reserved
4. Reserved
5. Chassis Gnd.
6. N/C
7. 9 V DC
8. Gnd
9. N/C
The “Mic in +” and “Mic in -” terminals are
for the balanced medium-low impedance
microphone inputs. The shield of the micro-
phone cable should be connected to chassis
ground on pin 5. A 9 V DC power pin allows
easy connection of electret (powered) mi-
crophones.
EXT 1 (Analog)
The Analog input is an eight-channel un-
balanced analog audio input from a digital
soundtrack player. The 25-pin D connector
is compatible with most decoders. Input
level should be 300 mV for all channels. See
Section 12.
EXT 2 (Digital)
The Digital input is a digital domain input
confi gured for eight channels (Four AES-
EBU pairs with sample rate from 32 to 96
kHz). Requires optional AES-EBU Module
(DI85). See Section 12
Non/Sync Inputs - Digital
Requires optional Module (DI83). An RCA
jack accepts S/PDIF inputs from CD, DVD,
or computer sound cards. Sample rates
from 32-96 kHz PCM are supported, AC3
bitstreams are also supported.
The DI83 module in this processor, which
decodes Dolby® Digital bitstreams, is not
intended for 35mm fi lm. The DI83 is intended
for alternative content only.
Auxiliary Inputs - Digital
Requires optional Module (DI83). An RCA
jack accepts S/PDIF inputs from CD, DVD,
or computer sound cards. Sample rates
from 32-96 kHz PCM are supported. AC3
bitstreams also are supported.
