InControl

 

Are a couple of highly innovative monoblock amplifiers allowed to be driven by a business-as-usual preamplifier? Definitely not.

The InControl project started exactly with this goal: to provide the InPower monoblocks with a control unit that was able to allow them to deliver all their impressive potential.
A goal not easily achieved: the research and development required two years of lengthy study and hard work. Fortunately though, as is custom at Pathos, the end result is one of excellence.

InControl is a two stage preamplifier entirely and intrinsically balanced, operating in pure Class A.
InControl has been developed according to all the traditional Pathos guidelines: tube tension amplification, solid state current amplification, well dimensioned power supplies and the highest quality selected components.

The amplification stage is obtained with a double triode in balanced configuration, while the output buffer is de signed with extremely low noise components, for a sonic result which favours musicality, transparency and naturalness.

In order to achieve maximum performance, all the single power supplies are obtained by means of single stabilized shielded power suppliers installed in a separate unit.

The volume control - which can be adjusted both by dialing the knob and via the hand :rafted solid wood remote control - is of the highest sophistication: it acts in 1dB steps by means of an optical device which drives a battery of relais (vacuum packed, with thorium contacts), which drive a network of precision resistors (1%,
metal layer). In a word, accuracy at its finest.

InTheGroove MKII

It has taken the excellent Pathos engineers many resources to develop a phono preamplifier superior to the original and highly appreciated InTheGroove. InTheGroove MKII is a high performance passive phono preamplifier designed for both MC and MM phono cartridges.The very refined sound follows the Pathos tradition of great soundstage, high realism, transparency, dynamics and musicality.

The InTheGroove MKII is a state of the art phono-amplifier that features completely independent left and right channel operation. Powered by batteries in order to provide as clean and stable power as possible. Since the output from the pick-up is low, the risk of “disturbing” the signal is higher. By using batteries in the power supply the risk of interference is minimised – the power is extremely stable and thereby avoids the turbulence that often appears on the mains net.

Another elaboration to ensure high sound quality is taken by using selected components of highest quality and balanced mode operation. Balanced layout is something rarely seen in phono amplifiers – but it has the advantages of lower noise and therefore a cleaner signal. The input-stage is the most critical in a phono-amplifier. The first gain stage is an ultra-low noise circuit to boost the weak signal from the cartridge. InTheGroove MkII uses JFETs to ensure the lowest possible input random noise. After the JFET input stage the very finest opamps handles the signal and ensures the correct gain. Together these initiatives ensure high gain, low noise and a peerless sound.

Gain is user selectable with an additional 20dB. The built in charger makes it easy to use and set-up. After a period with no signal it will switch off automatically and recharge if the batteries are low. This guarantees the longest life of the batteries. The variety of adjustments gives you a very user-friendly high-end phonostage – so you can get your cartridge to perform the best. The Pathos engineers have done their best to assure that you get the full value of your vinyl collection.
