Overview

MegaVoice introduces a small digital audio player, the Herald. The Herald is simple and cost effective - ideal for

teaching and training. Its intuitive, raised-button keypad makes navigating hundreds of hours of audio and

Scripture content quick and easy - even for the elderly or blind.

The Herald comes with fixed internal flash memory and a microSDTM card slot, making it simple for your ministry

team to update content and switch between different microSDTM cards. Load over 800 hours of tamperproof

audio content including: the Bible, New Testament, sermons, discipleship training, music, educational or

humanitarian messages, and load your ministry's audio content onto the microSDTM card as needed.

The MegaVoice Herald is designed to be less conspicuous and is powered by 2 AA batteries, making it ideal for

creative access applications. The Herald may be ordered with or without an onboard speaker (located in the

back of the unit). Both versions of the Herald provide a standard 3.5mm stereo earbud jack for personal

listening or can be plugged into the MegaVoice Solar Case Speaker so an entire congregation can hear the

Message.

Hardware Requirements

A Windows PC or Mac (Intel only)

At least 1 USB port (2.0 or higher)

Enough disk space for…

The SaberCopy software program (around 10 MB)

Each of your audio messages

Additional work area for restructuring message folders

At least 1 SLS USB cable with micro-USB connector (available fromMegaVoice)

A powered USB 2.0 hub (optional –for programming multiple playersconcurrently)

is no longer supported)

SaberCopy can work on Mac with certain restrictions (see here for details)

File Renaming Utility (free file renaming utility recommended by MegaVoice)

Herald User Guide 20180601-10.docx Page 7 of 48

Folder Structure

Structure Flexibility

Herald is very flexible in its file structure and supports any of 3 levels of folders and files for organizing your

audio messages:

3 levels: Section folders that contain Book folders that contain Chapters (audiofiles)

2 levels: Book folders that contain Chapters (audio files)

1 level: Chapters only (audio files)

The structure above you choose depends on how many audio files you have, how the messages were divided

into files and how you wish to group them for easiest navigation and playback.

For example, if your messages each span multiple audio files, you may want to treat a message like a Book

where the portions of one message (the individual audio files) are “chapters”.

If you have many messages dealing with the same topic, then the topic could be considered a “section” with

each of the “books” in that section of related messages.

But if your recorded messages are each contained in a single audio file, you could just as easily put them

all together as “chapters only” (a flat structure with all the files in a single folder).

The Herald supports free text for the naming of folders and files. The only restriction is that the names must sort

in the order in which the audio should be played for navigation by the player to work correctly.

To guarantee correct ordering, the names could all be prefixed with a 3-digit number followed by descriptive text

like “001 Healing Part 1.MP3”, “002 Healing Part 2.MP3”, “003 Admonishing.MP3”, “004 Fasting.MP3”, etc.

Herald User Guide 20180601-10.docx Page 8 of 48

Structure Limitations

The limitations for the Herald are as follows:

All audio files must be in MP3, WAV or WMA format. Files in any other audio format will be ignored.

All folder and file names may be in free text; however it is important that the folders and files sort in the

order the Herald should play them.

oFor guaranteed correct play order, MegaVoice recommends using a combination of a 3-digit prefix

followed by free text.

oFor example:

001 New Testament (Section)

001 Book of Matthew (Book)

001 Matthew Chapter 1 (Chapter)

002 Matthew Chapter 2 (Chapter)

Both the onboard memory and microSD card must adhere to one of the following folder structureoptions:

o3 levels (Sections, Books, Chapters):

There must be at least 1 (but not more than 199) Section folders in the audio project (root)folder

There must be at least 1 (but not more than 999) Book folders in each Sectionfolder

There must be at least 1 (but not more than 999) audio (chapter) files in each Bookfolder

The Book folder may not contain sub-folders or files of a type other than MP3, WAV or WMA.

There must not be any empty folders.

o2 levels (Books, Chapters):

There must be at least 1 (but not more than 999) Book folders in the audio project (root) folder

There must be at least 1 (but not more than 999) audio (chapter) files in each Bookfolder

The Book folder may not contain sub-folders or files of a type other thanMP3, WAV or WMA

There must not be any empty folders.

o1 level (Chapters only):

There must be at least 1 (but not more than 999) Chapter (audio) files in the audio project

(root) folder

The Root folder may not contain sub-folders or files of a type other thanMP3, WAV or WMA.

Relationship between the Keypad and Folder Structure

The Herald offers convenient navigation through hundreds of audio files. In order for this navigation to

work, you need to decide how you want your files to be partitioned.

Let’s get to know the Herald keypad and how the navigation buttons correlate to the required folder

structure.

This button scrolls backward

through the

Books and

Sections. A click skips 1 Book

while a 2-second press skips

1 Section.

This button scrolls forward

through the

Books and

Sections.

A click skips 1

Book while a 2-second press

skips 1 Section.

A click on this button skips

backward 1

Chapter (audio)

file

in the current Book. A

continuous press will fast-

reverse until the button is

released.

A click on this button skips

forward 1

Chapter (audio)

file

in the current Book. A

continuous press will fast-

forward until the button is

released.

This button controls

pause, resume and

setting the bookmark.

This button controls volume. There are

6 preset levels.

Each click increases volume by 1 level

until the maximum and then returns to

the minimum setting.

For those of you who are familiar with MP3 players or smart phones, it may be helpful to consider how we organize

our music: Artists, Albums and Songs.

We group our songs in albums and the albums are grouped per artist. We have a very similar structure for the

files on the Herald! Audio files are grouped into “Books” and Books are grouped into “Sections”.

A typical Bible from the MegaVoice Audio Library is divided into 3 Sections in the following way:

•001

Genesis through Job

18 “Books”

•002

Psalms through Malachi

21 “Books”

•003

Matthew through Revelation

27 “Books”

Each Section may contain one or more “Books”. The upper set of double-arrow buttons controls

forward/reverse navigation among the Books and Sections.

Each Book may contain one or more “Chapters”. The bottom set of double-arrow buttons control forward and

reverse navigation through the Chapters.

A click on these buttons will scroll

to the previous/next Chapter in the

current Book.

A continuous press will fast

reverse/forward through the

current Chapter until the button is

released or the beginning/end of

the chapter is reached.

A click on these buttons will

scroll to the previous/next Book

in the current Section.

A 2-second press will scroll to

the previous/next Section in the

audio project.
