Troubleshooting - Magenta MARGULES ARCH-3 Manual De Instrucciones

OPERATION (CONT):
To minimize unwanted noise or interference in the system:
1.- Avoid excessive length in the interconnection cables.
2.- Avoid having the cables near the alternating current line.
3.- Avoid ground feedback loops between components.
Burn-In Process:
About 150 hours of music playback are required. Having the unit on without music does not work for proper burn-in.
Vacuum Tube durability:
We recommend changing both vacuum tubes every three years for optimal performance, although they may last a more
extended period.
Type of compatible tubes or valves:
The unit has 12AU7 tubes or the ECC83 equivalency, do not use any other type of tube.
IMPORTANT: Never remove the tubes from the circuit while the equipment is connected to the wall or powered ON.
The unit has an AC outlet for associated equipment interrupted with a capacity of 15 amps, so you will be able to control the on
and off of the equipment connected to the ACRH-3.
It is usual for the input indicator to be lit while the unit is connected to the power supply.
If a sudden power loss causing two or more selection indicators to light, unplug the unit from the power outlet and redo the
initialization procedure (p. 7).
The unit's power cord can be exchanged for higher quality to improve the tonal characteristics.

TROUBLESHOOTING:

The equipment does not turn on:
Check that the power supply is correct and that the power cord is connected to a live electrical outlet.
Check the operating fuse (page 7 port 7). If the fuse is damaged, replace it with another of the same value (250V 6 AMP)
There is no sound:
The selector light is on, but there is no sound: Ensure the unit is turned on by checking the light in the upper left corner. Check
that the input signal is connected to the correct input.
Check the jumper between the PRE OUT 1 output and the AMP IN input. This jumper is pre-installed from the factory (page 6
ports 2 and 3).
If more than one indicator is lit:
A transient in the electrical current caused an error in the remote control logic.
Restart the unit by unplugging it from power and plugging it in again.
