Getting Started
This chapter covers connection requirements for Model 585 and the basics of using
the front-panel controls.
2.1 Unpacking and Inspection
Before unpacking Model 585, inspect the outer carton for shipping damage. If the
carton shows damage, inspect Model 585 in the associated areas. The BNC
connectors on the rear panel are covered with protective plastic caps.
The following items are provided with Model 585:
•
Three power cords: one each for US, continental Europe, and the UK. Use the
cord appropriate to your location.
•
A bag containing rackmount screws and washers, plus five 75
Ω
BNC
terminators.
•
Warranty information. Fill out the warranty card and return to Dolby
Laboratories. To receive software upgrades, register your product on the
software upgrades page at

2.2 Installing
Installing Model 585 requires:
•
Two standard rackspace units.
•
Digital I/O. The digital input and output connections on Model 585 may be
unfamiliar to a first-time user of a digital audio device. The Audio
Engineering Society (AES) created a standard electrical interface for digital
audio with a balanced XLR connector and 110
Ω
impedance called AES3-
1995. This interface was later expanded to include an unbalanced BNC
connector, 1 Vp–p signal level, and 75
Ω
impedance; it is now known as both
AES3-ID-1995 and SMPTE-276M. Model 585 uses this new standard for
digital audio electrical interface connections.
Note: These signals must be properly terminated with a 75
Ω
impedance at one point
only. We recommend a standard video terminator.
