Gold Note PH10 Phono Stage Black . In as new condition Fully working comes with all original packaging unused power cable and manual .loads of reviews out ther on this excellent phono stage . Heres the specs from gold note THE FIRST PHONO STAGE WITH 2 INPUTS AND 6 EQ CURVES PH-10 is an ultra-versatile phono preamplifier that offers unique features, including EQ CURVES, LOAD and GAIN adjustments: a fully analogue design engineered exclusively with high quality coils, capacitors and resistors. The EQ curves are implemented using analog circuitry realised with last generation integrated circuits and low noise components because we believe in the absolute superiority of a fully analog design over digital equalizers. Instead of the antiquated and inefficient electromechanical switches, we opted for electronic switches to select the curves: in this way PH-10 can preserve unaltered the audio signal and safeguard its purity without giving up on the use of digital technology. The use of electronic switches also helps shorten the paths of the audio signal to obtain greater efficiency and less dispersion. Digital technology is used only for real-time management of the display. PH-10 is controlled via knob and display using a sophisticated micro-controller to select the functions through our custom firmware that is loaded on a micro SD dedicated flash memory and can be updated easily via PC. The micro-controller is separated and independent from the audio signal path to guarantee always clear and pure sound. Once the tonearms are connected, PH-10 can be set with 4 different GAIN levels [-3dB, 0dB, +3dB, 6dB] to match precisely the output level of any MM or MC cartridge. The perfect setup is guaranteed with 9 different LOAD options [10, 22, 47, 100, 220, 470, 1000, 22K, 47K] that will let you adjust the preamp to match it with a large number of cartridges in a quick, easy way. HANDCRAFTED IN ITALY WITH PASSION AND TECHNOLOGY The secret behind PH-10? We design, craft and assemble every single part! Every PH-10 is handmade in Italy with the best audio grade components to ensure flawless music playback. The level of quality meets the highest standard throughout the entire production: from the CNC machining to the assembly and finally to the electronic tests at the PC. To maximize the performance of the PH-10, we developed PSU-10, the dedicated external super power supply that allows PH-10 to achieve its fullest potential reaching an even higher degree of musical realism, better dynamics and deeper three-dimensionality. 6 EQ CURVES TO DELIVER OUTSTANDING PERFORMANCES You will finally be able to switch from the internationally recognized RIAA curve, to the DECCA-LONDON or the AMERICAN-CBS-COLUMBIA curve, always graphically shown on the front display. And theres more, because you will also be able to enhance each curve with a modern Gold Note proprietary design for superior dynamic and powerful results. AUDIOPHILE IN EVERY POSSIBLE WAY PH-10 shows every detail on its 2,8 colour display powered by Gold Note proprietary SKC - Single Knob Control technology an intuitive control system developed to easily browse and select all the units functions. The unit can be externally powered by the dedicated external inductive power supply PSU-10 to enhance the performance even more . Specs 2 independent stereo RCA Inputs Weight: 3Kg Dimensions: 220mm W | 80mm H | 260mm D Subsonic filter: 10Hz/36dB octave Frequency response: 20Hz 20KHz [Enhanced 20Hz 50KHz] @ +/- 0.3dB THD (Total Harmonic Distortion): <0.05% MAX Signal to noise ratio: -89dB Dynamic response: 105dB Output impedance: 50 POWER Main supply: 100V to 245V, 50/60Hz (depending on market destination, not convertible) Power consumption: 30W super linear power supply AUDIO INPUTS Input capacitance MM: 220pF Input sensitivity: 0.1mV MC up to 7.0mV MM Input impedance: 9 selectable options [10, 22, 47, 100, 220, 470, 1000, 22K, 47K] Gain: 65dB MC - 45dB MM with 4 options [-3dB, 0dB, +3dB, +6dB] AUDIO OUTPUTS Line output level (fixed): stereo RCA @ 2Volt and balanced XLR @ 4Volt Upgrades The PSU-10 is a super inductive & chokes power supply designed exclusively for the PH-10 phono stage. PSU-10 has been engineered with the best quality audio-grade components to enhance the performance of PH-10 and improve even further your system: with the dedicated external power supply you will get the very best music experience out of your LPs. For PSU-10 we have chosen a dual choke design powered by a double inductor driving the negative and positive high current stages and featuring and inductive filter on the analogue stage. The Gold Note proprietary Dual Chokes Design perfectly filters the signal voltages in order to eliminate all the possible electrical pollution coming from the AC power system. The PSU-10 uses its massive power supply to shield the PH-10 phono stage from electro-magnetic interferences thus insulating it effectively from the AC power system. The large, ultra-clean power enhances super low noise, greater dynamic, better resolution and finer details for a more realistic high-end audio performance and pure audio pleasure. The PSU-10 can deliver high quality power using 4 transformers 3 of which are dedicated exclusively to the pure power supply and with 1 separated transformer dedicated to the inductive filter.
