Rear panel
Rear panel control and interface description:
-
AC IN AC power input interface
Insert one end of the power cord provided with the product to the interface and the other end to AC power socket. The input voltage is AC 220V. -
Output Signal output interface
Connect the sockets to the input socket of preamplifier or main preamplifier using an RCA cable. -
Input: MC (moving coil) signal input interface
Select the interface when using MC (moving coil) phono, and the phono will generate low-output voltage. -
MM Input MM (moving magnetic) signal input interface
Select the interface when using MM (moving magnetic) phono, and the phono will generate high-output voltage. -
GND: ground rod (ground wire)
Connect the ground wire in the output cable of turntable. Do not connect anything other than the ground wire of the turntable to the ground rod. -
MM/MC: input selector switch
Set this switch to match the phono type, choose to set · MC (moving coil) or MM (moving magnetic) phono.
Phono amplifier connection notes:
warning
- When replacing or using a power cord of another HIFI type, ensure that the power cord is intact.
- The configuration of the AC power input interface and the shape of the power cord plug vary with the country to which the product is exported. Use of any other power cord may cause a fire hazard or device damage.
- Before use, ensure that the voltage shown on the interface at the rear of the product is consistent with local AC voltage.
- Disassembling the product may result in a serious electric shock hazard.
- Do not touch the vacuum tube during and after use, as it may cause burns.
- If the product does not work, internal circuit boards or components may be damaged, do not attempt to open the product for repair; rather be sure to contact an analogue dealer or authorized service agent.
Fault Handling
Should a fault occur, please check the following items and try to troubleshoot
the fault before contacting customer service staff. If the program fails to
troubleshoot the fault even after the following operations are performed,
please contact an analogue dealer or authorized service agent.
Notes: Be sure to power off all components before changing any
connections.
- No power supply
- Ensure that the power cord is connected.
- No sound
- Make sure the turntable, preamplifier and other components are powered.
- Make sure the cable is properly connected.
- Make sure the input selector switch and input switch on the preamplifier are set correctly
- Make sure the phono and phono wire are connected correctly.
- One of the speakers has no sound
- Check whether the speaker cable and connection cable are connected correctly.
- Check whether the switch of the preamplifier is set correctly.
- Try to change the cable on A3 preamplifier (left/right).
- Try to change the connection of A3 left/right input cable.
- Noise
- Make sure the ground wire of turntable is connected correctly.
- If the A3 is near a power amplifier or other power supplies, please move it away until the noise disappears.
- Bind or twist the output cable and the ground wire of the turntable together, and isolate them from A3 power cord and the power cords of other components.
Change the fuse
If the fuse is blown, determine the cause first, then correct the problem, and
change the fuse after solving the problem. If newly installed fuses blow
continuously, disconnect the power cable and contact an authorized ANALOGUES
dealer for help. (Rated current of fuse is 3A), the fuse is located in the
power socket at the rear of the device.
Notes Use fuses of specified type and rated value only to avoid damage to
the device.
