8.4. Other connections
 USB CHARGE: type-A USB port for connecting mobile devices. This port is
designed for device charging only (5 VDC). Very useful if you are using a
device connected to eCOMPACT4BT using Bluetooth
®
connection and need to
recharge the battery. This avoids having to connect the Bluetooth
®
audio
device to a distant power outlet at the risk of weakening the Bluetooth
®
audio transmission.
12. USB charging port on front panel
 RS-232 port: for troubleshooting by the authorized technical service. It has
no use for the user.
9. OPERATION AND USE
9.1. Start-up
Once all connections have been made, turn on the eCOMPACT4BT by pressing the
power switch located on the rear panel. The POWER LED will light green.
In a complete audio installation, it is important to power on the equipment
according to the following sequence: sound sources (microphones, music players,
etc.), mixers, audio processors and finally power amplifiers. To power off, follow the
reverse sequence. In this order, the transients produced by switching the devices on
or off will not affect the next ones in the chain, remaining inaudible.
