However,
Pure power service most demanding:
In its high -end 7 series, the Swiss manufacturer Relotion offers the new power block 717. For example, In a more than imposed format, it provides an impressive instant power in order to supply all kinds of speakers. Similarly, Its design is exemplary, its price too.
Everything for figures – Pure power service most demanding
At this level of range, HiFi amplifiers pure power service most demanding must be beyond the exceptional. Furthermore, Rélotion has worked each item to get the best results and display the best measurement figures. Nevertheless, When all of this is recorded. Meanwhile, then we know that we are faced with a technically impeccable device that will theoretically operate any pair of speakers.
Let’s start with the separation of the channels which exceeds 120 dB. Similarly, To obtain such a result, Rélotion created the 717 as a double mono amplifier where each channel shares almost nothing. Nevertheless, The separation is optimal because the two cards for the right output and the left output are distinct.
The input floor of 717 offers optimal common mode rejection exceeding 105 dB, this without introducing noise. Moreover, This result is obtained thanks to the use of operational amplifiers put in parallel to target a large bandwidth. of 20 MHz. The objective here is for the amplifier to pure power service most demanding receive all the weakest audio signals, which can thus be reproduced correctly.
The 717 presents a bandwidth which does not stop at 20 kHz but which exceeds 2 MHz. Thanks to an ultra-linear counter-reaction network. the buckle gain exceeds 120 dB, this allowing to respect the response in phase at 20 kHz with a deviation less than 0.2 °.
Up to 2×6. 000 watts in snapshot – Pure power service most demanding
Relision 717 is a stereo amplifier operating in AB class through 16 transistors per channel. A control circuit checks the instantaneous current of each transistor. consequently modifies its rest current so that all operate under identical conditions. The 2×300 watts under 4 ohms can become 2×6000 watts for a moment in order to respond to any. type of current call necessary for the realistic reproduction of music. This represents up to 400A.
The output impedance of the pure power service most demanding food being controlled, it always remains very low, which makes large capacitors useless. Instead, multiple power supplies are associated with high -performance direct current converters. They are located right next to the dissipators. This guarantees minimal noise and the shortest path possible for the signal.
The 717 is equipped with two XLR stereo entries. It is possible to switch from one to the other via the front keys. The display confirms the entry during listening. An XLR stereo output allows you to chain several amplifiers. Different control ports (RS232, trigger and owners) are used to control the ignition and extinction of the device.
Who is the Roice 717 to?
The stereo amplifier Rélution 717 aims at the wealthiest audiophiles which already have the more exclusive speakers of production. To make them work in optimal conditions. nothing like the 717 and its disproportionate instant pure power service most demanding power to reproduce, among other details, the transients as in reality. This exceptional power block is offered at the rate of 120000 €.
