SAFETY INFORMATION
1. To ensure the best results from this product, please read this manual and all other documentation before operating your equipment.
Retain all documentation for future reference.
2. Follow all instructions printed on unit chassis for proper operation.
3. To reduce the risk of re, do not spill water or other liquids into or on the unit, or operate the unit while standing in liquid.
4. Make sure power outlets conform to the power requirements listed on the back of the unit. Keep unit protected from rain, water and
excessive moisture.
5. Do not attempt to clean the unit with chemical solvents or aerosol cleaners, as this may damage the unit. Dust with a clean dry cloth.
6. Do not use the unit if the electrical power cord is frayed or broken. The power supply cords should be routed so that they are not
likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords and plugs, convenience
receptacles, and the point where they exit from the appliance.
7. Do not force switched or external connections in any way. They should all connect easily, without needing to be forced.
8. Always operate the unit with the AC ground wire connected to the electrical system ground. Precautions should be taken so that the
means of grounding of a piece of equipment is not defeated.
9. AC voltage must be correct and the same as that printed on the rear of the unit. Damage caused by connection to improper AC
voltage is not covered by any warranty.
10. Turn power off and disconnect unit from AC current before making connections.
11. Never hold a power switch in the “ON” position.
12. This unit should be installed in a cool dry place, away from sources of excessive heat, vibration, dust, moisture and cold. Do not use
the unit near stoves, heat registers, radiators, or other heat producing devices.
13. Do not block fan intake or exhaust ports. Do not operate equipment on a surface or in an environment which may impede the normal
ow of air around the unit, such as a bed, rug, carpet, or completely enclosed rack. If the unit is used in an extremely dusty or smoky
environment, the unit should be periodically “blown free” of foreign dust and matter.
14. To reduce the risk of electric shock, do not remove the cover. There are no user serviceable parts inside. Refer all servicing to
qualied service personnel. There are no user serviceable parts inside.
15. When moving the unit, disconnect input ports rst, then remove the power cable; nally, disconnect the interconnecting cables to
other devices.
16. Do not drive the inputs with a signal level greater than that required to drive equipment to full output.
17. The equipment power cord should be unplugged from the outlet when left unused for a long period of time.
18. Save the carton and packing material even if the equipment has arrived in good condition. Should you ever need to ship the unit,
use only the original factory packing.
19. Service Information Equipment should be serviced by qualier service personnel when:
A. The power supply cord or the plug has been damaged.
B. Objects have fallen, or liquid has been spilled into the equipment.
C. The equipment has been exposed to rain
D. The equipment does not appear to operate normally, or exhibits a marked change in performance
E. The equipment has been dropped, or the enclosure damaged.

Audio Connection
Audio Output
Default Output: 2x 20Watt@4 Ohm
The default output of the amplier is 2x 20Watt@4 Ohm, so user can connect the amplier in stereo. As the picture below:
Connecting all four pins.
Bridge Connection: 1x 40Watt@8 Ohm
The ANI-PA has the bridge connection, to double the output power at 1x 40Watt@8 Ohm. It will sum up the input left channel and input
right channel to be mono output, and the power is up to 40Watt.
The bridge connection is:
Connecting only two pins.
Dual-Mono Output:
The ANI-PA also has the function of double-mono output. It can sum up the left and right channel, to be mono audio output. In this way,
both of the outputs are showing the same mono audio.
The connection is:
Connecting all four pins.
