LV 58SER40A DIGITAL AUDIO (Dolby Decoding Capability Optional)

Plug-In Unit

The LV 58SER40(A) (DIGITAL AUDIO)
operates as an AES/EBU I/O unit when
installed in an LV 5800 input slot or the LV
7800 or as an AES/EBU output unit when
installed in an LV 5800 output slot. It
allows the LV 5800 to display Lissajous,
sound image, level meter, and signal sta-
tus displays*

for data in 8 AES/EBU chan-

nel pairs (16 channels)*

and 2 analog

audio channels.*

If the LV 58SER01A (SDI INPUT) is-
installed in the LV 5800/7800, this unit can
process AES/EBU signals that are embed-
ded in SDI signals. If the LV 58SER04
(MPEG DECODER) is installed, this unit
can process MPEG-1 Layer 2 signals,
MPEG-2 AAC signals, and LPCM signals
that are embedded in DVB-ASI signals.

FEATURES

• 8 AES/EBU I/O Pairs (16 Channels)

The LV 58SER40(A) is equipped with 4 AES/EBU channel pairs
(8 channels). Installing the optional I/O expansion unit expands
the I/O connectors to 8 AES/EBU channel pairs (16 channels).
This unit operates as an AES/EBU I/O unit when installed in an
LV 5800 input slot or the LV 7800 or as an AES/EBU output
unit when installed in an LV 5800 output slot.

• ITU BS. 1770-I Loudness meter
• Surround Display (5 LEAF)
• Headphone Output

When you install this unit into an LV 5800 input slot or the LV
7800, you can listen to the audio of the selected channel using
headphones.

• Various Display Features

This unit enables the LV 5800 to display the following items on
the AES/EBU input signals.
• Single Lissajous display between any two channels
• Multi Lissajous display that simultaneously shows 4 or 8 single

Lissajous displays of different channel pair combinations.

• Sound image display
• Meter display
The unit also enables the LV 5800 to display the following
AES/EBU signal status bits.
• Channel status bit
• User bit
• Validity bit
• Parity bit

* You cannot assign the audio measurement display to multiple areas

• Analog Audio Input

The LV 58SER40A can measure analog audio signals on 2
channels.

• Dolby Decoding Capability (Optional)

* Dolby E, Dolby Digital is a trademark of Dolby Laboratories.
