Fusing Information

WARNING: To reduce the risk of fire, replace fuses only with the same type

and rating.

Both units use a universal switching power supply that handles the full range of

nominal mains voltages between 90 and 264 VAC and any frequency between 50 Hz

and 60 Hz.

Check Main Fuse

The Main fuse rating is:

T 1A L (1 Amp, 250 V, 20 mm, time-lag, low breaking capacity) for all operating

voltages.

WARNING: The power to the unit must be off when the following steps are

performed. Ensure that the main power cable to the unit is not connected to a

power source.

1. Open the fuse compartment door in the AC power input housing with a small flat-

blade screwdriver (Figure 1). Carefully pull out the fuse carrier.

2. Check that the replacement fuse has the correct rating. The fuse carrier must be

inserted into the compartment carefully. Do not force the carrier into the

compartment or both could be damaged.

3. Snap the fuse compartment door closed.

Figure 1 Checking the Main Fuse

Intern al Fu se

The switching power supply contains a separate fuse. Most fault conditions should be

protected by the main fuse.

If you find it necessary to replace the internal fuse, be certain to replace it with a fuse

of the same type and rating as printed on the switching power supply board.

Linear Acoustic AERO.2000 User Guide

Chapter 1: Introduction to AERO.2000

The Linear Acoustic AERO.2000 Audio/Loudness Manager is a state-of-the-art, adaptive, multiband,

broadcast audio/loudness processor. The AERO.2000 can apply loudness control and upmixing to

ten input channels. It outputs 5.1 processed channels, an LtRt version of the main audio channels, and

two separate two-channel programs (stereo or mono).

Professional audio metadata can be applied to AERO.2000 to minimize processing and control func-

tions, such as upmixing. AERO.2000 protects itself against loss of incoming metadata with reversion

modes that apply plant reference loudness values. The resulting audio is clean, consistent, and appro-

priately dynamic - perfect for consumer transmission via Dolby® Digital (AC-3) or any other format.

The AERO.2000 includes the following features:

• Program configurations: 5.1+2+Local + 2+2+Local support 16 audio channels

• AEROMAX® multiband loudness processing provides ATSC, ITU and EBU compliance

Includes Input AGC, parametric EQ, multiband AGC and limiting, look-ahead peak limiting,

and selectable multiband source noise reduction

• ITU-R BS.1770-3 meter for each output program simplifies loudness target calibration

• Selectable dual upmixers utilizing industry-standard UPMAX® II algorithm

• Full-time LtRt or LoRo downmix of main 5.1 channel program

• HD/SD-SDI I/O for embedded audio and VANC metadata

• Dual, redundant, auto-ranging power supplies

• Decoding options: Dolby Digital and/or Dolby E

• Encoding option: Dolby Digital (AC-3)

• GPI and Ethernet control

• Nielsen® Watermark Encoding option

This rest of this chapter includes:

• a description of back panel connectors;

• system block diagrams

• an introduction to AERO.2000’s displays, menus, and navigation

• a summary of important setup parameters.

See Connector Pinouts on page 41 for AES and analog connector, Metadata, and GPI pinout tables.

1.3 Power

The AERO.2000 is equipped with two power supplies (dual PSUs). Always connect BOTH power in-

lets to clean AC power sources, ideally from separate feeds. Remember, this is primarily to protect you

against unreliable power sources, and not from problems with AERO.2000’s power supplies.

We strongly recommend using an uninterruptible power supply (UPS) on at least one of the AC power

feeds; separate units should be used for each inlet.

Apply AC power to power on the AERO.2000; there is no power switch. The blue light behind the

Linear Acoustic logo illuminates, the LCD screen shows the Linear Acoustic logo, and fans turn on.

When the menu appears on the LCD screen, startup is complete and the unit is ready to use. This pro-

cess may take up to two minutes.

To power off, just remove both AC power cords from the unit.

1.4 Navigation

The right, left, up, and down arrow keys navigate AERO.2000’s menu system:

Figure 1-4 Menu navigation keys

• ► Next Takes you into the selected menu; same as Enter

• ◄ Prev. Takes you back the same path; same as Back or Esc

• ▲▼ Scrolls through screen parameters

The central rotary knob adjusts the selected parameter.

Linear Acoustic AERO.2000 User Guide Introduction to AERO.2000

1.5 Menus

AERO.2000’s menus are hierarchical, and follow logical signal processing flows.

A parameter changed from its stored value is displayed in yellow. When stored, it returns to white.

AERO.2000 employs the “breadcrumbs” tactic so you’ll always know where you are in the menu hi-

erarchy. The top of the each menu displays your current position. For example, Figure 1-5 shows the

menu position as AERO.2000 * System * System * System Information.

The menu displays tips and hints in yellow to explain a function or why it is inactive. For example,

Figure 1-5 (right) shows why the IP Address field is grayed out and inactive.

Figure 1-5 Left: menu path at top; Right: yellow popup hint

Linear Acoustic AERO.2000 User Guide Introduction to AERO.2000

1.6 Display Setup

The front panel display can be fully customized, and can contain up to six meters of the same or dif-

ferent types. The display can also be set to “Meters Only” mode so the menus are temporarily hidden.

Of course, display resolution may limit the number of active front panel meters, but all six will work

fine using the AERO.2000 VGA output.

The left side of Figure 1-6 shows Display 1 set to DRC, Program 1 and Display 2 set to Loudness (for

Pgm 1), and Displays 3–6 off.

The right side of Figure 1-6 shows the same metering configuration set to full screen.

1.7 Important Setup Parameters

1.7.1 Reference

The AERO.2000 can be referenced to:

• AES DARS (or any AES signal applied to the Ref In connector);

• AES In 1

•SDI

• Internal 48 kHz (standalone use only).

NOTE: If SDI embedding is enabled, clock reference will be forced to SDI automatically. Otherwise, proper

reference MUST be selected for glitch-free operation!

Figure 1-7 shows the clock reference set to SDI. The menu’s yellow lettering indicates that it has been

changed from the saved value. Saving again turns it white. Note again the menu path displayed at the top.

Figure 1-7 Clock Reference set to SDI

Linear Acoustic AERO.2000 User Guide Introduction to AERO.2000

1.7.2 Audio Input Select

Since a single physical input can feed multiple instances, each instance has a built-in router to select

audio on a pair-by-pair basis.

Figure 1-8 Left: inputs for a given instance; Right: available choices for AES or SDI pair

1.7.3 Audio Output Routing

Since one physical Output can come from just one source, a single output router configures each of

the 16 AES and 16 SDI outputs.

Figure 1-9 Left: main AES outputs (BNC and DB25) and SDI outputs; Right: SDI output setup

Note that any one Instance or Encoder output can go to all physical outputs if desired. Any AES or

SDI input signal pair can be routed to any AES or SDI output pair with no processing.

Linear Acoustic AERO.2000 User Guide Introduction to AERO.2000

1.7.4 Ethernet

The Ethernet connection, like the reference signal, must be stable and always present. Audio glitches

may be heard on air if Ethernet is interrupted. Although initially configured for DHCP (auto-IP ad-

dress), static IP addresses can also be entered explicitly.

Figure 1-10 Left: IP address, remote port, and MAC address; Right: reconfiguring IP settings

1.7.5 Video Compensation Delay

Included video compensation delay can help re-time audio and video/ancillary data signals from SDI

In to SDI Out to match processing delay. Exact processing delay will depend on the presence of Dolby

encoding/decoding and Nielsen Watermark options, and normal practice is to set the video delay to

the next whole video frame value (different for NTSC and PAL of course). Rough timing is via the

delay control (milliseconds) and the Fine control can adjust to the microsecond. Once video delay is

set, A/V lip-sync can be accomplished in the I/O Menu using the Utility Audio Delays
