shock, do not perform any servicing other than that contained in the operating instructions unless you

are qualiﬁed to do so. Refer all servicing to qualiﬁed personnel

This instrument has an auto-ranging line voltage input. Ensure the power voltage is within the speciﬁed

range of 100-240VAC. The ~ symbol, if used, indicates an alternating current supply. Equipment must

be connected to protective earthing by means of a power cord connected to a socket outlet. Equipment

with an earthing terminal should be connected to a proper ground system with 20 – 14 AWG (0.5 –

1.5mm) wire.

This symbol, wherever it appears, alerts you to the presence of uninsulated, dangerous voltage

inside the enclosure – voltage which may be suﬃcient to constitute a risk of shock. Disconnect

equipment from all power sources before any servicing of parts.

This symbol, wherever it appears, alerts you to important operating and maintenance instruc-

tions. Read the manual.

This symbol, whenever it appears, identiﬁes the associated terminal as an earth ground for

protection against electric shock in case of a fault. The terminal should be connected to a

proper ground system with 20 – 14 AWG (0.5 – 1.5mm) wire.

This symbol, whenever it appears, indicates a fuse to protect against excessive current. When

replacing fuses, use only the type and rating of the original fuse as indicated by the manufacturer. Never

install a fuse with a higher current value.

CAUTION: HAZARDOUS VOLTAGES

The instrument power supply incorporates an internal fuse. Hazardous voltages may still be present on

some of the primary parts even when the fuse has blown. If fuse replacement is required, replace fuse

only with same type and value for continued protection against ﬁre.

Introduction

1 Introduction

Congratulations on your purchase of the Linear Acoustic LA-5300 Broadcast Audio Processor.

The LA-5300 provides everything broadcasters need to be ready for NEXTGEN TV/ATSC 3.0 audio in a single,

compact, integrated package, including:

♦ Dolby® AC-4 encoding from PCM

♦ Transcoding from Dolby Digital and Dolby Digital Plus to Dolby AC-4

♦ Dolby AC-4 decoding for audience measurement watermarking and bitstream analysis and monitoring

♦ Linear Acoustic UPMAX® ISC upmixing

♦ Optional Verance and Nielsen watermarking

♦ Loudness control via Dolby Real-Time Loudness Leveler (when encoding to Dolby AC-4)

Optionally, it also provides processing for a second legacy ATSC 1.0 program, including:

♦ Dolby® Digital Plus (E-AC-3) and Dolby Digital (AC-3) encoding

♦ Linear Acoustic UPMAX® ISC upmixing

♦ Optional Verance and Nielsen watermarking

♦ Loudness control via Linear Acoustic APTO® or Dolby Real-Time Loudness Leveler

Standard I/O includes 3Gb/s HD/SD-SDI, AES-3, and AES67 to support SMPTE ST 2110-30 and -31 workﬂows.

Quad-Link 3Gb/s SDI I/O for supporting 4K workﬂows or MADI I/O (mutually exclusive with one another) are

optional.

Additional features dual 1000BaseT Ethernet connections (one each for control and AES67), and a web-based

user interface for setup, conﬁguration, routing, control, and metering.

About This User Guide

A printed copy of the LA-5300 Quick Start Guide was included with your LA-5300 and will walk you through the

rear panel connections, setting up and conﬁguring network control, and basic I/O and program routing. A PDF of

the QSG is available for download from our website at https://www.telosalliance.com/Linear/LA-5300.

This manual will provide more detailed information, including an in-depth description about speciﬁc functions

and controls.

Note

The LA-5300 is also available in a decode and monitor-only version which omits upmixing, watermarking,

and AC-4 encoding (which includes loudness control). Accordingly, some menus, screens, and controls will

look dierent from those seen here.

Using the Front Panel Interface

Physical Installation

The LA-5300 is a 1RU product intended to be permanently installed in a standard 19

1

/2” equipment rack and

secured with four standard rack screws.

LA-5300 is fan cooled with air intakes and exhausts located on the side of the unit just behind the front panel, but

whenever possible it is recommended to leave 1RU of empty space above and below the unit.

Important:

Please see the “User Warnings and Cautions” section of this manual for important electrical safety information.

Power

The LA-5300 has two internal auto-ranging redundant power supplies protected by type T1AL25V fuses. Remem-

ber that while redundant supplies do protect against the unit losing power in the event of a PSU failure, the loss of

mains supply voltage is a bigger concern. Accordingly, each supply should be fed from a diﬀerent circuit equipped

with adequate surge protection and ﬁtted with an uninterruptable power supply (UPS). Providing the recep-

tacles to which the supplied power cords are connected are grounded, the power connection serves as a ground.

Additionally, the rear panel earthing terminal should be connected to a proper ground system with 20 – 14 AWG

(0.5 – 1.5mm) wire.

Front Panel Buttons

As mentioned brieﬂy in Chapter 2, the front panel of LA-5300 includes a ﬁve-button navigation cluster with Left,

Right, Up, and Down arrow buttons plus a green “OK” button in the center.

The arrow buttons are used for navigating through the menus, and the “OK” button acts as an “Enter” or “Select” key.

Installation and Initial Setup Using the Front Panel Interface

The Home Screen

The IP address of the network Control port (used to connect to the remote user interface) is shown in the lower

left corner. If a network connection is detected, the IP address will be yellow. If there is no network connection, the

IP address will be red.

The primary reference clock source and status is shown in the lower right corner. Green indicates an active solid

reference. Red indicates an inactive or missing reference.

Figure 3-1 – Front panel Home screen

The Information Screen

Pressing the Right button navigates to the Information screen.

The name of this particular LA-5300 and its location are displayed at the top of the screen. These values can be

customized using the remote interface as detailed in Chapter 6.

The unit’s unique serial number is shown next, followed by the current ﬁrmware version, the IP address of the

Control port (the port used to connect to the remote interface), the IP address of the AES67 port (the port used to

carry AES67 AoIP), and the current active clock reference.

IP Conguration Screen

Another press of the Right button brings you to the IP Conﬁguration screen for the Control port.

Figure 3-3 – Front panel IP conﬁguration screen

Important!

The Control and AES67 Ethernet connections both require 1000BASE-T (Gigabit) switch ports in order to

work properly.

If both the Control and AES67 ports will be used, they must be in dierent subnets. In-band control is

available using the AES67 port.

If only one port will be used, set the unused port to “Static IP” with an IP Address of 0.0.0.0, a Subnet Mask of

0.0.0.1, and a Gateway of 0.0.0.0.

By default, the LA-5300 will automatically obtain an IP address from a DHCP server which will suﬃce to provide

initial remote access to the unit for conﬁguration purposes. A ﬁxed IP address will be preferred in most cases and

can be set as follows:

1. Press the OK button to highlight “Edit”

2. Press OK again to highlight “Use DHCP”

3. Press the Right button to highlight “Yes”

4. Press the Up/Down button to “No”

5. Press the Left button to highlight the “Static IP Address” ﬁelds

a. Press the Down button to highlight “Address”

b. Press the Right button to move to the ﬁrst digit of the IP address

c. Use the Up/Down buttons to change the selection

d. Press the Right/Left buttons to select another digit to edit

e. When ﬁnished editing the address ﬁeld, press the Right or Left button to return to “Address”

f. Press the Down button to navigate to the Netmask and Gateway ﬁelds

6. Repeat the above steps to edit the Netmask and Gateway ﬁelds; note that the gateway may be set to

000.000.000.000 if no gateway is required

7. After the gateway is set, press the Left button to highlight “Gateway”

8. Press the Down button to highlight “Update”

9. Press OK to save the new IP information

10. If you suddenly notice you’ve entered some incorrect information and need to bail out and start over, use the

Right/Left buttons to highlight “Cancel” followed by “OK”

Locate Mode

Our sincere hope is that you like your LA-5300 so much that you’ll eventually end up with dozens of them pop-

ulating your racks, but since one LA-5300 looks pretty much like another, we’ve come up with a way to help you

identify an individual unit.

When you enable the “Locate Mode” from the remote user interface, the unit’s front panel display will repeatedly

change color until Locate Mode has been cleared by pressing any key on the front panel or by clicking again on the

“Locate Mode” button on the remote user interface. Enabling Locate Mode aﬀects only the unit’s display, and has

no eﬀect on the audio.

Special Function Key Presses

Performing a full Factory Reset and engaging the Hardware Relay Bypass are possible from the front panel by

pushing and holding a particular combination of buttons.

Factory Reset

To reset the unit to its factory defaults, simultaneously press and hold the Left, Up, and Right buttons for ten

seconds until a red countdown timer appears in the bottom left corner of the display.

Important!

Performing a factory reset will erase all I/O routing as well as any other custom settings you may have saved.

This information cannot be reclaimed once you reset the LA-5300, even by contacting customer support

or feeling genuine remorse for your decision. We strongly recommend backing up your conguration to a

computer before performing a factory reset to avoid re-setter’s remorse. You have been warned!

Hardware Relay Bypass

LA-5300 includes a hard relay bypass that removes all internal circuits and processes from the signal path and

connects each SDI and AES-3 input directly to its corresponding output.

To toggle the relay bypass on and oﬀ, simultaneously press and hold the Left, Down, and Right keys for three sec-

onds until a red countdown timer appears in the bottom left corner of the display. Do not confuse this sequence

with the Factory Reset procedure described above.
