Operation

1.  Plug the Power Cable to the amplifier and into the electrical outlet.

2.  Turn on the amplifier – press the Power Switch (the Power Switch should be in the 

down position 

 ). 

 

The status LED around the Power Switch should turn orange in a few seconds. 

 

If it does not, it means that the amplifier is working under an abnormal condition (a 

protection mode) – turn off the power, unplug the Power Cable and check whether 

some of the cables are not short circuited. 

 

After fixing the cables turn the amplifier on.

3.  Using the Input Selector knob select which audio source you want to play 

(corresponding to the selected input).

4.  Turn on your audio source and start playback.

5.  Regulate volume on the amplifier to adjust the level of sound.

 

 

Note! 

Check “Additional Information” for other useful operating instructions.

 

 

Note!

 High volume levels can damage this amplifier and/or speakers. This may 

void your warranty.

Play from USB Stick:

This amplifier can play music from most USB sticks and supports most MP3 / WMA / 

WAV / APE audio files.

1.  Using the Input Selector knob select the USB input.  If the USB stick is not inserted 

then the USB/Bluetooth Input Status Led Indicator will start flashing.

2.  Insert the USB stick into the USB Input socket located on the front of the amplifier.

3.  When compatible music files are detected then the playback will start 

automatically.

 

In the Play mode the USB/Bluetooth Input Status Led Indicator will be illuminated 

continuously.  

4.  Press the USB Knob ►

clockwise to play the next song. If the last song is 

detected the playback will start from the first one on the USB stick (check “Order of 

file playback”).

6.  Rotate the USB Knob

◄◄ counterclockwise to play the previous song. If the first 

song is detected the playback will start from the last one on the USB stick (check 

order of file playback).

Order of file playback:

The music files are always played in accordance with their alphabetical order on the 

USB stick and its folders. Usually the playback starts from the files stored directly on 

the USB stick (which are not placed in the folders) and then the playback is continued 

for the files stored in the folders according to a folder order on the USB stick.

Note! 

Depending on a USB stick type, format and number or arrangements of folders 

and files some music files will be played differently or will not be recognized by the 

amplifier.

Note! 

We recommend to change input to other one before removing the USB stick.
