Amplifier Sunfire TGA-7201In contrast to the Rotel RMB-1575, here in the circuit of the power supply used high-grade toroidal transformer, which affected the weight of the model. However, implementation of innovative circuit design of the output stages Sunfire TGA-7201 has achieved a high return amplifiers and do without bulky heatsink. As a result, developers were able to build the machine in the case of rather modest size. In the left-hand side flaunts an impressive toroidal transformer, and due to this asymmetric arrangement of the unit's weight is distributed unevenly, which should be considered when carrying it. Behind the front panel mounted most common power supply board. All seven amplification channels arranged in four boards, placed along the body, three of them are identical, two channels each and one somewhat different - it is mounted seventh amplifier circuits of the power supply. Cooling radiators as there are none, their role is played by the very bottom. Between the boards gain is tiny cooler, but judging by the small number of vents and completely deaf top cover, special cooling problems filling in this phone is not. The output stages are based on the field (MOSFET) transistor providing up to 80 At the output of each of the seven channels of amplification. In fairness, we note that the housing Sunfire TGA-7201 after our rather extensive testing has remained virtually cold. Rear plugboard surprising abundance of different terminals. Each balanced input on XLR connector is added a pair of unbalanced inputs RCA. More precisely, to call this a couple of inputs is not quite correct, because the scheme allows the use of the second connector for parallel amplification - just connect the interconnects second "input" one channel (which will work as an output) to the input of the amplifier, and it will now work in parallel. In addition, the front channels are equipped with two types of gain outputs for connecting speakers - current (current source) and voltage (voltage source). The first option is recommended for switching electrostatic or planar speakers, as well as the acoustics equipped with tape emitters. Amplifier provides the advanced integration capabilities in the multi system. There are just three input triggers. The apparatus or method includes a standard manage potential 12, or by the presence of the useful signal at its input. Disabling occurs in the latter case the timer if no useful signal input for 30 minutes. Also on the rear panel there is a three-level switch luminescence intensity single LED on the front panel indicates the presence of power. By the way, besides the LED on the front of no more than nothing, not even the power button. The main switch is mounted at the back that is not very convenient when the unit is in a rack, - apparently, the developers involve the use of a new technique of remote control. Accompanying movies amplifier was able to form a virtually seamless sound field teeming with tiny nuances. However, the pressure and the impact it is slightly outperformed by the leaders of our test. With careful study of the entire operating range would be more biting feeding energetic pulses. Musical material by Sunfire TGA-7201 sounded a bit dry and sharply - in the sound was a lack of emotion. ![]() |
