8.2 Modification of the Main Volume

The volume of the player can be set in different ways. The last applied volume is always retained when the
player is switched off, except with the [V+xx] and [V-xx] tags.
With the knob of the player
•
Turn the Volume/-Menu- knob to change the main volume of the player. (See the section Main
Volume Control Using the Knob.)
With the infrared remote control
•
Use the Volume+ and Volume- buttons of the infrared remote control to change the main volume of
the player. (See the appendix Infrared Remote Control.)
During the playback of a folder or of a file
•
Use the [V+xx] and [V-xx] tags to change the volume during the playback of a folder or of a file.
This modification is relative to the main volume for folders, and to the volume of the folder for files.
(See the chapter Control of the ChronoPlayer with the Folders and the Files.)
Note: In this specific case, the relative volume is not be retained if the player is switched off.
With a command on the RS-232 serial link
•
Use the 03h command of the RS-232 protocol of the player to change its main volume. This
command can be sent from any peripheral equipped with an RS-232 serial link (another ID-AL
player, a computer, a PLC, etc.). (See the chapter RS-232 Serial Link Protocol.)
With the configuration file
•
Define #VOLUME in the setup file to change the main volume of the player each time it is powered
on. (See the chapter Configuration File.)
Note: This volume setting is always applied upon startup, whatever the previous volume
modifications.
