thanks Steve, the model - 618.
mobile multi media amplifier - built in mp3 player.
power - 30 w - 150 w
F/R - 38 hz - 20 KHz
impedance 4 ohms
Sensivity - 88 dB
A/C 220/240 V - 50/60 Hz
As soon as I switch the power switch on position the speakers starts humming/buzzing and you can not control it with the volume its a straight humming sound from the speakers.
The second thing I did myself was disconnect the speakers and powered the unit and there was no sound but as soon as I hooked the speakers it started again.
The system has one USB port and a SD/MMC card slot for playing music.
Also it has a mic 1 input port/mic 2 input port and a guitar input port.
Yes, thats correct I do not plug anything into this ports but I use the USB port & SD card port for playing music.
One more thing I forgot is the toroid transformer gets very hot when switched on.
Toroid transformer - input 220V/50Hz
output 24V- ov 24 V
Who is assisting me right now?
