A1 Stereo Power Amplifier Operating Manual
Anedio A1 Power Amplifier 1 Welcome Thank you for purchasing the Anedio A1 Power Amplifier! Anedio is founded upon the principle that the enjoyment of highestquality music should be available for everyone, not just for the esoteric few. Our quest is to attain the most realistic and faithful reproduction of music, enabling the listener to experience its beauty, pathos, joy, and delight more fully.
2 Anedio A1 Power Amplifier Important Safety Instructions The lightening symbol within an equilateral triangle is intended to alert the user to the presence of un-insulated dangerous voltage within the product’s enclosure that may constitute a risk of electric shock. The exclamation mark within an equilateral triangle is intended to alert the user to important operating and maintenance instructions. 1. Read these instructions. 2. Keep these instructions. 3. Heed all warnings. 4. Follow all instructions.
Anedio A1 Power Amplifier 3 14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.

Anedio A1 Power Amplifier 5 Setting Up Placement of the Amplifier Place the amplifier between the two loudspeakers, instead of setting it off to one side. This keeps the lengths of interconnects and speaker cables short for optimal sonic performance. Remember that the ideal cable is no cable. The signal can never be improved by going through a longer cable. As you shorten the cable length, the signal fidelity approaches that of the ideal cable.
6 Anedio A1 Power Amplifier and those of the loudspeakers. Never connect the output terminals to the chassis or to the ground. This will cause a short circuit and may damage the amplifier. The outputs are balanced, i.e., both positive (+) and negative (-) terminals move differentially with respect to the ground, and they are not to be shorted to the ground.
Anedio A1 Power Amplifier 7 When turning on and off your music system, the power amplifier should be the last component to be turned on and the first component to be turned off. This prevents power on/off transients from being transmitted to loudspeakers. Power Indicator LED The blue LED light at the center of the front panel, along with the blue side bars, indicate that power is on.
8 Anedio A1 Power Amplifier Passive Bi-amp Mode Normal (Stereo) Mode For normal (stereo) operation, set the bi-amp switch to “NORMAL.” This is the default setting. The switch is intentionally recessed so that its setting cannot be changed accidentally. Why Passive Bi-amplification? Passive bi-amplification can improve the sonic quality of the system in a subtle but significant way. The Anedio A1 Power Amp is conceived specifically to take full advantage of the benefits of passive bi-amplification.
Anedio A1 Power Amplifier 9 can be significant, revealing another layer of sonic information. We believe that a pair of amplifiers with moderate current capacity, when used in passive bi-amplification, is sonically superior to a single amplifier with massive current capacity.

10 Anedio A1 Power Amplifier IN1 and IN2 are internally connected together in the passive bi-amp mode). Please note that this mode can be used only for those loudspeakers that have separate terminals for low and high frequency drivers. Two A1 Amplifiers are requires for a stereo setup in the passive biamp mode. Make sure that the shorting jumpers across the high and low frequency drivers of the loudspeakers are removed for the passive bi-amp operation.
Anedio A1 Power Amplifier 11 Specifications Continuous Power Output: 70 watts per channel (8 ohms) 75 watts per channel (4 ohms) Both channels driven simultaneously Dynamic Power Output (CEA-2006): 90 watts per channel (8 ohms) 105 watts per channel (4 ohms) Both channels driven simultaneously Total Harmonic Distortion + Noise: 0.0007% @ 1KHz (60W into 8 ohms) 0.0010% @ 1KHz (70W into 4 ohms) Intermodulation Distortion: 0.
12 Anedio A1 Power Amplifier Trouble Shooting Symptoms Remedy No power • • Ensure the power cord is plugged in fully. Check the fuse. If blown, ensure that the outputs are not shorted. Replace it only with 2A/250V 5x20mm time-lag (slow-blo). Using an incorrect fuse will void the warranty. Power on but no sound • Ensure that the source component is turned on. Ensure that the interconnects and cables are plugged in fully and seated properly.
