1 Preface The Audionet AMP1 V2 is a stereo audio power amplifier of highest performance and finish quality, and long-life stability. This system is designed for absolute natural music reproduction. The following will give you all information about how to operate your AMP1 V2. Please read this carefully before the first use. Following these instructions, your AMP1 V2 will give you long-lasting pleasure and satisfaction.
1.1 Included Included you will find the following items: · the stereo power amplifier AMP1 V2 · the user's manual (that you are currently reading) · one standard mains cord 1.2 Transport Important · Please transport the AMP1 V2 only in the included package. · Always use the plastic bag to prevent scratches on the housing. · Please allow the AMP1 V2 to adapt to the climatic conditions in your listening room before you switch on the unit for the first time after transport.

4 Installation and power supply Important · For connecting or removing loudspeakers and/or the preamplifier your AMP1 V2 must be switched off to prevent damage to the amplifier or the connected units. · Please make sure that all cables are in absolute best conditions! Broken shields or short-cut loudspeaker cables could damage speakers and/or amplifiers. 4.1 Placement The compact design of the AMP1 V2 requires the unobstructed heat dissipation during operation.
· Never pull the mains plug while the AMP1 V2 is switched on! Before you pull the mains cord off the socket, power down the unit to standby mode. Only in cases of extended absence (like vacations) or if massive trouble on the mains power is to be expected you should remove the AMP1 V2 form the mains. To disconnect the unit completely from mains pull both mains plugs. Note · Using high-quality mains cords as the Audionet P10, may improve the sound quality. Please consult your local Audionet dealer.
5 Inputs and outputs Important · For connecting or removing loudspeakers and/or the pre amplifier your AMP1 V2 must be switched off to prevent damage to the amplifier or the connected units. · Please make sure that all cables are in absolute best conditions! Broken shields or short-cut loudspeaker cables could damage speakers and/or amplifiers. 5.1 Inputs The AMP1 V2 has two RCA inputs 1 and 8 for the connection of a pre amplifier, e.g. Audionet PRE G2.
Note · The nominal loudspeaker impedance should be 2 Ohms or higher. · Never use force or tools tightening the terminal screws. 5.3 Bi-Wiring If your speakers support bi-wiring, use two separate cables to connect each speaker to the output terminals 2 and 7 of the AMP1 V2. Impulse response and spatiality may improve significantly. Note · Again, please mind the correct polarization of the speakers! 5.
5.5 Audionet Link For your convenience, the AMP1 V2 can be controlled remotely by one of Audionet's multi channel pre amplifiers (e.g. MAP or MAP 1) as well as one of Audionet's stereo pre amplifiers (e.g. PRE G2, PRE 1 G3) using the Audionet Link interface. You only need a optical 'Toslink' cable to connect the Audionet Link output of your Audionet pre amplifier to the Audionet Link input IN 3 of the AMP1 V2. In case you would like to automatically switch on/off further Audionet units in your system (e.g.
6 Operating 6.1 Powering up First of all, please make sure your AMP1 V2 is connected correctly to your pre-amplifier, speakers and mains (see section 'Installation and power supply' on page 8 and section 'Inputs and outputs' on page 10). The AMP1 V2 is a stand-by unit.
7 Protection system Your AMP1 V2 has a powerful protection circuit to prevent damage of the amplifier itself or the loudspeakers connected. In case of trouble the AMP1 V2 is switched to stand-by state.
8 Technical information 8.1 Construction The AMP1 V2 is constructed as a dual-mono amplifier. SMD techniques are used to optimise high-frequency characteristics. All signal paths are reduced to minimum length. No elements malicious to sound quality (i.e. coupling capacitors, coils, relays) are located in the signal path. The construction is magnetically and capacitively optimised.
9 Security advice · Avoid packaging material, especially plastic bags, to come into children’s hands. · Store and operate the unit in a dry room at a reasonable room temperature. · Avoid moisture or any liquid to get into the unit. · Set up the unit in a free position so that the air is allowed to flow through the unit slits. · Do not cover, e.g. with a blanket. · Do not open the case. Unauthorised opening will cause loss of guarantee. · Use a dry cloth for cleaning.
