Chapter 2 Getting Started

This chapter covers connection requirements for Model 585 and the basics of using

the front-panel controls.

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. U se the

cord appropriate to your location.

• A bag containing rackmount screws and washers, plus five 75Ω 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 www.dolby.com/download/softreg.

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 110Ω impedance called AES3-

1995. This interface was later expanded to include an unbalanced BNC

connector, 1 Vp–p signal level, and 75Ω 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 w ith a 75Ω impedance at one point

only. We recommend a standard video terminator.
