PLEASE READ BEFORE PROCEEDING!

Manual

The Operating Manual contains instructions to verify the proper operation of this unit and initialization of certain options. You will find these operations are most conveniently performed on the bench before you install the unit in the rack.

Please review the Manual, especially the installation section, before unpacking the unit.

Trial Period Precautions

If your unit has been provided on a trial basis:

You should observe the following precautions to avoid reconditioning charges in case you later wish to return the unit to your dealer.

(1) Note the packing technique and save all packing materials. It is not wise to ship in other than the factory carton. (Re-

placements cost $35.00).

(2) Avoid scratching the paint or plating. Set the unit on soft, clean surfaces.

(3) Do not cut the grounding pin from the line cord.

(4) Use care and proper tools in removing and tightening screws to avoid burring the heads.

(5) Use the nylon-washered rack screws supplied, if possible, to avoid damaging the panel. Support the unit when tighten-

ing the screws so that the threads do not scrape the paint inside the slotted holes.

Packing

When you pack the unit for shipping:

(1) Tighten all screws on any barrier strip(s) so the screws do not fall out from vibration. (2) Wrap the unit in its original plastic bag to avoid abrading the paint. (3) Seal the inner and outer cartons with tape.

If you are returning the unit permanently (for credit), be sure to enclose:

• The Manual(s)

• The Registration/Warranty Card

• The Line Cord

• All Miscellaneous Hardware (including the Rack Screws and Keys)

• The Extender Card (if applicable)

• The Monitor Rolloff Filter(s) (OPTIMOD-AM only)

• The COAX Connecting Cable (OPTIMOD 8685 and OPTIMOD 8685 only)

Your dealer may charge you for any missing items.

If you are returning a unit for repair, do not enclose any of the above items.

Further advice on proper packing and shipping is included in the Manual (see Table of Contents).

Trouble

If you have problems with installation or operation:

(1) Check everything you have done so far against the instructions in the Manual. The information contained therein is

based on our years of experience with OPTIMOD and broadcast stations.

(2) Check the other sections of the Manual (consult the Table of Contents and Index) to see if there might be some sug-

gestions regarding your problem.

(3) After reading the section on Factory Assistance, you may call Orban Customer Service for advice during normal Cali-

fornia business hours. The number is (1) 510/351-3500.

This equipment generates, uses, and can radiate radio-frequency energy. If it is not installed and used as directed by this manual, it may cause interference to radio communication. This equipment complies with the limits for a Class A computing device, as specified by FCC Rules, Part 15, subject J, which are designed to provide reasonable protection against such interference when this type of equipment is operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference. If it does, the user will be required to eliminate the interference at the user’s expense.

This digital apparatus does not exceed the Class A limits for radio noise emissions from digital apparatus set out in the radio Interference Regulations of the Canadian Department of Communications. (Le present appareil numerique n’emet pas de bruits radioelectriques depassant les limites applicables aux appareils numeriques [de las class A] prescrites dans le Reglement sur le brouillage radioelectrique edicte par le ministere des Communications du Canada.)

Perform the installation under static control conditions. Simply walking across a rug can generate a static charge of 20,000 volts. This is the spark or shock you may have felt when touching a doorknob or some other conductive surface. A much smaller static discharge is likely to destroy one or more of the CMOS semiconductors employed in OPTIMOD 8685. Static damage will not be covered under warranty.

There are many common sources of static. Most involve some type of friction between two dissimilar materials. Some examples are combing your hair, sliding across a seat cover or rolling a cart across the floor. Since the threshold of human perception for a static discharge is 3000 volts, you will not even notice many damaging discharges.

Basic damage prevention consists of minimizing generation, discharging any accumulated static charge on your body or workstation, and preventing that discharge from being sent to or through an electronic component. You should use a static grounding strap (grounded through a protective resistor) and a static safe workbench with a conductive surface. This will prevent any buildup or damaging static.

OPTIMOD SURROUND PROCESSOR INTRODUCTION

Introduction

Crucial Information—Please Read!

To make automatic loudness control as straightforward and dependable as possible, the 8685 operates somewhat differently from other Optimods.

• Dialnorm: The 8685 works very easily with Dolby Digital® transmission systems

if you do one crucial thing: You must tell the 8685 what value of Dolby Digital Dialnorm metadata you are transmitting to your audience. This will prevent your transmission from being too loud or quiet compared to other correctly set up Dolby Digital transmissions.

1-1

• The 8685’s Quick Setup

ting Dialnorm on the 8685. Step 10 on page 2-14 explains how the 8685 uses its knowledge of transmitted Dialnorm to control loudness.

• Your Dolby Digital transmission’s loudness will automatically be correct if:

• you use a “TV” factory preset (Table 3-1 on page 3-27),

• you

• Setting Output Loudness: To set the 8685’s output loudness, adjust its

preset. Both methods cause 8685’s O

have adjusted the 8685’s input reference level so that the processing operates with normal amounts of gain reduction (step 7 on page 2-11 or step 7 on page 2-25), and

have adjusted the 8685’s Dialnorm to match the Dialnorm you are transmitting (step 10 on page 2-14 or step 13 on page 2-34).

The 8685’s DIALNORM value can be set in two places: There is a global setting in the active Setup, which can be overridden by a setting in the active processing preset. Except for the 2.0 parameters in the analog TV presets, all factory processing presets are configured to use the global Dialnorm setting specified in the active Setup.

You can use the 8685’s RS-485 serial ports (serial ports #2 and #3 on the back panel) to convey D Conveying Metadata on page 2-15.

IALNORM value or adjust the MB LIMITER DRIVE control in the active processing

wizard (page 2- 8) leads you through the process of set-

IALNORM to the Dolby-Encoder automatically. See

INTRODUCTION ORBAN MODEL 8685

• Adjusting D

on the 8685’s CBS Loudness Level meter or the amount of gain reduction in the loudness controller. The peak limiter’s gain reduction will change. This is the preferred method if the 8685’s loudness controller is active because it has the smallest effect on the sonic texture of the 8685’s audio processing.

IALNORM changes output loudness without changing the indication

• Adjusting MB

the amount of gain reduction in the loudness controller and peak limiter.

The 8685’s output level controls (called SURROUND OUTPUT 100% and 2.0 OUTPUT 100% for the surround and 2.0 processing chains respectively) do not change output loudness. Their only purpose is to set the 8685’s maximum peak output level with respect to 0 dBfs, which allows you to compensate for transmission channels that introduce peak overshoots. For example, if you lower an O the 8685 automatically reduces the gain following its peak limiter by 2 dB and simultaneously increases the drive into the peak limiter by 2 dB. Hence, the average output level does not change but the maximum peak output level is constrained to –2 dBfs. This unconventional arrangement results from the 8685’s handling of Dialnorm—if you have set D correctly on the 8685, you can change the 8685’s output level control freely without causing your on-air loudness to be incorrect with respect to other transmissions.

If you are processing for a Dolby Digital distribution channel and wish to customize a factory preset, see Setting Preset Loudness Correctly for Dolby Digital Transmission on page 3-19.

LIMITER DRIVE changes the Loudness Level meter’s indication and

UTPUT 100% control from 0 dBfs to –2 dBfs,
