RCM SENSOR 2 Hi-End Phono Preamplifier MM/MC

With separate power supply unit

SENSOR2 is a phono preamplifier pushes the performance of it's predecessors even further. it Has evolved from our experience and attempts to improve the parameters of a device as demanding as it gets. Designed and manufactured to achive the maximum possible results with available resources and technology, yet no part is here by accident. Every decision is based on experience, allowing us to utilize optimal results while retaining attractive price point. 

Just like the first version, SENSOR2 stands out from other phonopreamplifiers with it’s high output level. Our experience led us to the conclusion that a value of at least 1 volt is necessary to retain a high-quality sound. It’s caused by many factors, including the higher level signal preference of the input step. The best solution would be to increase that number to 2 volts – same as an average CD player. Doing that imposes some high requirements for the entire device, since, for MC cartridges with output at 0,3mV, that would require the signal to be amplified by 76dB – over 6300 times! 

SENSOR2 allows you to select between single-ended or balanced outputs. The signal coming from the cartridge is symmetrical, which enables an appropriate configuration of the input to widen it’s dynamics ranges while limiting the noise. Why should you fix what’s not broken? 
Setting the load impedance is done via the switches on the back of the device. SENSOR2 features an 8-way switch that allows more options, which, in turn, leads to more precise setup of the amplifier. Also in the back you’ll find the switches that allow for setup of gain and output stage mode (single-ended or balanced).

Another very important part necessary to achieve overall success is the power supply. SENSOR2 features a symmetrical power supply that is constructed to minimize signal distortion. Great care has been paid to selecting the capacitors in the filtering circuit and lowering the output impedance of the amplifier.

     This extensive upgrade results in increased dynamics, lower noise floor and a larger sound stage both in width and depth. Anyone familiar with Sensor Prelude will be most impressed when they hear the improvements in Sensor 2 that is delivered with only a modest increase in cost over the original. At it’s price point Sensor 2 is still exceptional value for money just like before, only better now.
