The CANOR PH 2.10 is an all-tube phono preamplifier for MM and MC cartridges. It contains the minimum number of amplification steps required to apply purely passive corrections. PH 2.10 is designed concerning the highest possible sound quality. Made of a massive, welded structure additionally reinforced by an internal partition, which also has a secondary function of electrical shielding of the source part from the amplifying circuits.
The whole connection is without any global feedback, which results in excellent sound performance, but it places extremely high demands on the selection of used electronics.
The use of CMT ™ technology (CANOR ® PCB Milling Technology) was a matter of course in the design of printed circuit boards.
Because very small signal amplitudes are processed in the turntable preamplifier, this technology has been even more beneficial than in our other products.
To remove mechanical hum, the transformer core is vacuum impregnated, and the entire transformer is encapsulated in a special anti-vibration compound. In addition, the massive, welded cover in which the transformer is located creates effective electromagnetic shielding and contributes significantly to the excellent signal-to-hum distance.
The primary and secondary windings are separated by a shielding copper foil with a 50% overlap, which prevents the penetration of interfering voltages from the network.
The only high-quality polypropylene capacitors are used in the signal path. If the turntable contains two arms and an MM port is installed on one and an MC on the other, they can be connected at the same time without any interference.
The RCA MM or MC input is selected on the front panel using the buttons.
The PH 2.10 allows an exceptionally large variability of gain adjustment and selection of the correct values of resistances and capacitances for all types of transmissions. All these settings can be made conveniently using the controls located on the front panel.
The MC cartridges are connected to the preamplifier input using a high-quality Lundahl step-up transformer.
This preamplifier allows the RCA connection to the power amplifier.
The PH2.10 contains 2 x 12AX7 and 2 x 12AT7 tubes and it is designed without overall feedback. The first and second amplification stages are made up of 12AX7, among which a subsonic filter is put. The third and fourth stages are made up of 12AT7. The RIAA correction is passive and consists only of quality polystyrene and polypropylene capacitors. The output capacitor is also of high quality (polypropylene foil).
