Installation
Before installation, please ensure power is switched off and mains unpluged
from the wall to avoid damage to equipment and installer.
Wire speakers to the amplifier as shown above, ensure the positive and negative terminals are wired correctly. Audio input on the back is through 3 pairs of RCA connectors, ensure left and right signals are correct for stereo output. Finally, insert the IEC plug and connect the unit to the mains. Before switching on, always ensure the master volume is set at the lowest point to avoid power surge damage to the unit or speakers. Adjust the volume accordingly to an appropriate listening level.
Impedance Matching
AS60-BU is capable of 4-82 impedance output if more than one speaker is to be
connected to the amplifier per channel. Please ensure the total impedance of
the speakers is within the range. Speakers can be wired in two different ways,
in parallel or in series. The total impedance can be worked out by the
following formulas for the two different ways of wiring:

Troubleshooting
No Power| Check the mains is sw itched on and the power lead is in good
condition and fully inserted into the wall socket.
---|---
Check IEC plug is fully inserted into the amplifier on the back.
Check power switch is switched on on the amplifier.
Check if the fuse is faulty . If the fuse blows too frequently, stop use of
device immediately and refer to qualified personnel for repair.
No Music output| Check the input connection lead is fully inserted on both
amplifier and source.
Check the correct input is selected.
Check the audio source is playing.
Check volume is turn up on both amplifier and audio source.
Check speaker cable is not damaged, end striped and connected properly on both
amplifier and speakers.
Check for any loose strands on the speaker cable that is touching the positive
and negative terminal, this will trigger the short circuit protection.
No Mic output| Check Mic is switched on.
Check Mic volume is turned up on the ampli fier .
Check if Mic requires phan tom power.
Check if Mic is working properly on other device.
Diminishing output| Check speaker polarity is connected corre ctly.
Check audio source volume is turned up.
Check impedance of the speaker/ s is within the range.
Disrupted output| Check output volume is not too high on both audio source and
amplifier .
Check for damage on speaker cable and connection leads.
Check amplifier, audio device, speaker and connection cables are not near any
mains power cable or large inductive appliances such as a fridge.
