6. DIRECT CONTROL
Direct control (with the control keys) is possible when the DMX signal is absent (DMX LED off)
only. You can operate with the four following keys:
PLAY/STOP - plays / stops / pauses / restarts playing
VOLUME "+" and "-" - adjust the volume level
NEXT - next track selection
PREV - previous track selection
7. DMX CONTROL
With the DMX protocol the player control can be held through four or seven channels. In the 7-
channel control mode the following features are available: play / stop / restart, track number
selection, reproduction mode (one track or all tracks once and one or all tracks in a loop), volume
adjustment and a three tone equalizers (high, medium and low). When the 4-channel control
mode is set the equalizer is unavailable - you can adjust the tones manually in the player's menu
(dEF section).
When the PX154 player is switched on, the software version number is displayed. After
approximately 2 seconds the currently played track number appears. The direct control with the
functional keys is possible, when the DMX signal is absent. The player starts with the 0 volume
level and selects (does not play) track no. 000 then. The equalizer is set at the default level, as
well as the single playing of one track. By pressing the PLAY/STOP key you can start playing the
selected track. The special case is the "run" feature activated (refer to p. 8.3 of the manual).
When both volume keys are pressed simultaneously you can enter the player's menu, where the
following parameters can be set: the DMX address, number of DMX control bytes, player reaction
to DMX signal absence or interruption and the played track parameters.
ATTENTION: When the SD/MMC memory card is empty, the player can be used as the Master
Mass Storage device, that is a removable disc, only! The control with the functional
keys will not be possible.
Moreover, the number of files put on the SD/MMC card cannot exceed 26. If there is more files or
any additional folders are put on the memory card, it can cause improper player operation during
tracks changing. All the mp3 files must be saved in format 000.mp3, 001.mp3, ... , 025.mp3.
