FOR A LIMITED TIME- FREE SHIPPING! phono-2 is a result of continuous learning which made it possible to meet high level performance of phono-1 and, at the same time, provide more convenient optimization for wide variety of MM and MC cartridges. This is the perfect choice for both a non-technical music lover and eternal hifi optimizer and tinkerer. The robust steel chassis houses preamplifier circuits and stabilized and filtered power supply. External power supply is a simple line frequency transformer, dislocated to eliminate influence of electromagnetic fields on the sensitive electronics. Bottom side of phono-2 hosts micro switches which are used to set cartridge loading ("Load"), preamplifier gain ("Gain") and output filtration ("Low-pass filter"). Examples of optimum load and gain settings for various cartridges are listed here. Eight discrete loads can be set by using individual switches. (47k, 22k, 10k, 1k, 500 ohm, 200 ohm, 100 ohm and 47 ohm). The cartridge load is set by engaging switches as indicated by the legend printed between the switches. By combining loads, many more different combinations are possible (for example - combining 22k and 10k switches, the resulting load will be 6.8k). If that is not sufficient, similarly to phono-1's load and gain optimization phono-2 can have unlimited settings available by removing top cover and accessing terminals for insertion of additional loading resistors and capacitors. Those terminals are marked R11 and R12 for loading resistors and C11 and C12 for loading capacitors. NOTE: in order to accurately load the cartridge with the additional resistors, all microswitches on teh rear panel should be in the OFF position. When adding loading capacitance, the default capacitance of 50pF should be accounted for: as an example - if the total loading capacitance of 200pF is desired, additional capacitor needs to have value of 150pF. Capacitors and resistors with lead diameter in the range of 0.025-0.032" (0.6-0.8mm) can be safely inserted. Larger diameter may cause damage to the sockets. There are six different gain setting possible: 40dB, 50dB, 55dB, 60dB, 65dB and 70dB. The preamplifier gain is set by engaging microswitches as indicated by the printed legend next to the switch. The phono-2 features an innovative extension of phono-1's active offset cancellation circuit to provide output filtration without adding capacitors into the signal path.There are three available settings: 1) No Filter: this setting leaves only the active offset cancellation engaged and bandwidth of the preamplifier goes down to 2Hz. 2) 10Hz, Slow roll-off filter: with this setting engaged, phono-2's bandwidth goes down to 10Hz, but roll-off starts at about 40Hz. We have found this setting helpful with records equilized by IEC RIAA curve. 3) 10Hz, Fast roll-off filter: our version of subsonic (rumble) filter. Bandwidth goes down to 10Hz, but roll-off starts below 20Hz, thus having no effects on audio frequencies. Specifications: Wide adjustment rage suitable for MM and MC cartridges Direct Coupling (no capacitors in the signal path) Class A operation Bandwidth: 10Hz-40kHz Input impedance- Eight presets: 47 ohm – 47 kohm, plus sockets for custom loading resistors Gain: Six presets: 40-70dB Passive RIAA compensation Active offset Cancellation Gold plated PCB Steel case for EMI shielding Dimensions : 7.25 x 4 x 1.5" (185 x 100 x 40 mm) NOTE: Buyers in NY State should add sales tax of $35 (8.875%) for the total of $434.00 The package contents: - Phono-1 Mk II preamplifier - External power supply, 120V input This product comes with 2-year warranty and SPECIAL 30 days return privilege.
