1.2.3 4xAES Input (AES/EBU)
This 25‐pin female D‐connector receives four AES3 streams, which are linked to the digital
1 button. Typically, this input connects to a Dolby Digital cinema server. It accommodates
PCM audio at 96, 48, and 44.1 kHz (16, 20, and 24 bit), Dolby Digital at all data rates and
sample rates, and Dolby E at frame rates of 23.98 (24 pulldown), 24, 25, 29.97, and 30 fps.
The decoding of coded audio (Dolby Digital or Dolby E) is restricted to the first AES3
channel pair. The clocks for all four pairs are derived from pair 1. This connector has a
floating ground.
1.2.4 1xAES Inputs (AES3)
These BNC connectors are linked to the digital 2 and digital 3 buttons respectively. They
accommodate PCM audio at 96, 48, and 44.1 kHz (16‐, 20‐, and 24‐bit), Dolby Digital at all
data rates and sample rates, and Dolby E at frame rates of 23.98 (24 pulldown), 24, 25, 29.97,
and 30 fps. A BNC male to RCA female adapter can interface with most consumer gear.
These connectors have floating grounds.
1.2.5 S/PDIF Optical Input
This Toslink optical connector is linked to the digital 4 button. It accommodates PCM audio
at 96, 48, and 44.1 kHz (16‐, 20‐, and 24‐bit), Dolby Digital at all data rates and sample rates,
and Dolby E at frame rates of 23.98 (24 pulldown), 24, 25, 29.97, and 30 fps.
1.2.6 Digital Media Automation Connector
This interface connects to a theatre automation system. It is a 9‐pin female D‐connector
providing ground‐switching control of the front‐panel input selection buttons. It has a
floating ground. The automation system can switch between film sound (pass‐through)
and any of the four digital media sources. This function duplicates the front‐panel digital
input buttons and the film button. Two pins (6, 7) provide relay dry contact closure
whenever you select either digital 1, digital 2, digital 3, or digital 4 (the relay contacts open
when Film mode is selected) for CP200 digital subwoofer logic control.
1.2.7 RS-232 Serial Port
You can use this port for serial control using ASCII string commands. Set this port to 9600
and 8 1 and use a pin‐to‐pin serial cable. You can also perform the same function using
the Ethernet port, as described in Section 1.2.8.
1.2.8 Ethernet Port
This is an illuminated RJ45 10BASE‐T Ethernet port with activity LEDs, which provides an
interface to a Dolby Digital Cinema network and also ASCII string commands through
telnet protocol to port 61412. You can also use this port for setup software and firmware
upgrades.
