AX 3800
Thank you
for choosing another quality product from Amperes Electronics.
AX3800 provides a better way of a standby amplifier to overtake a failed duty unit automatically in PA installation. Packed
with efficient circuitry with features such as overload protection, interval Pilot Tone generation and data output for remote
monitoring, it shall be the right choice for setups with lesser human interaction in ensuring uninterrupted operation of PA
system.
Though it is rather simple in the installation works, a brief read through the manual is recommended and we are confident
that you are getting a product of excellence.

Page 2: Parts Identification
Pilot tone shall be sent at intervals to every channel of amplifier inputs. Whenever this is sent, the LED shall lit. 6. FAULT BUZZER Whenever a faulty channel is detected, a buzzer shall be activated and the alarm can be switched off while the red LED shall remain on.

Page 9: How It Works
Although in principle most auto fault changeover works similarly in detecting faulty amplifiers, you may find some difference in how AX3800 operates. AX3800 sends out Pilot Tone of 20 KHz at intervals and shift from channel to channel. This reduces strain at the amplifiers in which continuous loading is avoided. Though some slight delay may occur during the detection period, this shall be beneficial in the long run. - Page 10 After channel 6, switch on the power amp in sequence from Ch6 to 1 and the results shall be as opposite to the earlier procedures.
