AMC是英国著名发烧功放品牌 发烧友都知道是入门机的最佳选择,性价比高，该机品质稳定，典型英国声，音乐感强，高中低平衡度一流 解析力非常高 音色与质感耐听，非常适合听室内乐，人声和弦乐、轻音乐等
3025功放为合并机：功率30x2W（8欧）、60x2W（4欧）。
APPLICATIONS AND FEATURES
• Unique phono stage design that employs two audiophile grade op-amps per channel that provide very low THD, TIM and noise, together with switchable MM/MC sensitivities.
• The high overload tone control stage can be completely by-passed with the DIRECT switch to give
natural sound quality.
• Special designed passive Tone control circuit to give natural sound quality.
• Uses audiophile grade components through out, providing exceptional accuracy to phono and tone control responses.
• High overload margin on tone control circuit by virtue of its topologies.
• Power amplifiers with 30 Amp high peak output current devices to offer capabilities to drive almost all types of speaker systems.
• Power amplifiers with special designed perfect virtual image topology to make it possible to be without output relays. The topology connects amplifier outputs to speaker systems without relay contacts to offer best possible sound quality.
• Using high output current devices with optimized power supply designs, the power amplifiers can be only protected with fuses on power supplier side in order to delivery extremely high output current in demand to give superb sound quality.
• With universal power transformer passed all international safety standards, end users can uses the unit in all countries by rewiring the voltage links inside the unit by authorized distributors or dealers.
• Heavy duty gold plated loud speaker binding posts and phono connectors for ultra reliable connections.
• Use Analog to Digital converter and dedicated microprocessor to convert motorized pot positions to select proper input by selecting from front panel by hand or from remote control. (This is a patent pending design of Weltronics Corp.) Once you press the remote control, the input selector rotary knob will be driven by motor to the position selected and input switch will select the selected input. This give AMC product a very reliable way of making remote input selector into rotary type that normally other manufacturers has to spend a lot of money to do the same job in order to give the neat and elegant analog way of input selecting.
• The ADC/ microprocessor type of remote rotary control will make it possible to do any number of inputs in the future as required.
• The volume control uses high end motor driven type of VR to give sound quality same as high end pre-amp without remote control.
• The volume control also controlled by the same dedicated microprocessor controlling the rotary input selector. This make it possible to have the unit controlled by AMC standard codes - the AMC C-Bus codes.
• 3025a will be upgraded to be with AMC C-Bus connector on rear panel in order to be able to be connected to other AMC products with AMC C-bus connector including to go with AMC RCP01, Remote Control Pad to control from remote locations or through Power lines via AC outlets.
