RIAA Phono Preamplifier This phono preamplifier for Moving Magnet (MM) and Moving Coil (MC) pickup systems is based on the legendary Douglas-Self-Design. MM & MC There are two pickup systems for record players: Moving Magnet (MM) and Moving Coil (MC). Moving Magnet Moving magnet pickups generate a small voltage by moving a magnet between copper coils. MM pickups have a very high inductance and impedance. The Phonos offers a choice of three capacitors to correct the linearity of the frequency and phase response. The capacitances are 150pF, 220pF and 330pF. In the off-position the capacitance is determined by the capacitance of the cable. Moving Coil The MC pickup is also a small electromagnetic generator, but with the magnets firmly anchored and the coils moving between them, i.e. exactly the opposite of the MM pickup. The output voltage, however, is very low at only a few hundred microvolts and is therefore more sensitive to noise and induced hum. This makes preamplifier design a challenge, because the very low output voltage must be pre-amplified extremely noise-free. Phonos offers one of the most powerful phono preamplifiers for MC systems with up to 71.5 dB preamplification. Thanks to the 120V technology, the preamplifiers are extremely low-noise, linear and phase-locked. MC pickups have a very low inductance and impedance. This means that the effects of cable capacitance (from turntable to preamplifier) are negligible. The impedance, however, is relevant and can be set in six positions: 100, 220, 470, 2.2 k, 4.7 k, and 10 kOhm. If there is any doubt as to which impedance matches that of the pickup, the impedances can also simply be switched through until the linear frequency response is acoustically determined. Amplification The pre-amplification can be switched in three values. The normal gain value is +46 dB for MM and +67 dB for MC cartridges. In the -10 dB position, the phono produces enough output level for normal hi-fi equipment operating at a reference level of -10 dBV. In the +4 dB position, the output level is about as loud as that of modern DA converters at a reference level of 0dBfs = +15 dBu. Subsonic Filter The rumbling of the turntable’s drive mechanism is also amplified by the high amplification of the bass range due to RIAA equalization in playback. The Phonos offers a switchable subsonic filter to remove this rumble.  Connections Gold-plated RCA sockets are available for connecting the turntable and for outputting to a preamplifier such as the Director Mk2 or the Elector.  A ground connection for the turntable is designed as banana plug socket. The ground lead can be either clamped or plugged in. RIAA Equalization RIAA equalization is a specification for the recording and playback of records proposed by the Recording Industry Association of America (RIAA). The RIAA equalization curves introduced a global de facto industry standard for vinyl records in 1954. RIAA equalization uses pre-emphasis to reduce low frequencies and boost high frequencies when the record is cut (blue RIAA curve). The bass is reduced by up to 20 dB to provide more space and longer record play time. The high frequencies are boosted by up to 25 dB to increase the signal-to-noise ratio between the noise and the hot of the record media to the audio signal. During playback, exactly the opposite happens in the phono. The de-emphasis filter (red RIAA curve) compensates for the pre-emphasis and the result is a linear frequency response. Douglas Self Design The RIAA equalization of the phono was developed according to the recommendations of Douglas Self. Idea: Many small capacities instead of a few large capacities. Advantages: The capacitors charge and discharge faster, which results in better resolution and faster impulse response. Only audiophile Styroflex capacitors are used in the entire RIAA equalizer. About the person: Douglas Self is a British electronics engineer with a strong penchant for audio. He holds honorary degrees from Cambridge University and teaches psychoacoustics at the University of Sussex.

The MX-VYNL is a fully balanced, very high performance phono stage, able to operate with virtually any moving coil or moving magnet cartridge. With both traditional RCA inputs and our unique XLR fully balanced connection the MX-VYNL can be connected to 2 turntables simultaneously.The MX-VNYL offers a wide range of input impedance settings for moving coil cartridges as well as several capacitance settings for moving magnet units. Unlike many of our competitors units the MX-VYNL allows easy adjustment of these settings while playing. This allows easy experimentation and tuning to find the optimum setting for all your equipment.The MX-VYNL also includes our renowned RIAA correction that offers extremely accurate results to beyond 80kHz. That may sound extreme, but there is a good deal of information above 20 kHz that needs correction. If it isn’t corrected, it will show itself as ringing and overshoot.With both extraordinarily low noise and exceptional overload margin the MX-VYNL can comfortably handle even the most demanding of cartridges and satisfy the most discerning of listeners.Features:Fully balanced XLR and traditional RCA inputsFully balanced XLR and traditional RCA outputsFully isolated inputs allow for switching between two turntables at onceAdjustable input impedance on MC whilst it is playingAdjustable capacitance on MM whilst it is playingVery wide overload marginAccurate RIAA to beyond 80kHzIncredible noise ratioLow impedance outputState of the art SMD technologyBeautiful aesthetics and build quality
