Clearaudio Absolute Phono
The world's first active headshell moving coil phonostage.
The absolute phono inside uses the absolute phono's innovative circuit design including the current amplification first gain stage. However in the Inside, this is incorporated within the phonostage's main body. Through careful fine tuning, Clearaudio have been able to deliver many of the improvements bought about by the absolute phono in a more conventional phonostage configuration. Both unbalanced RCA and balanced XLR inputs are provided for connection to any tonearm on the market. These feed the fully balanced current amplification first gain stage, avoiding any need to set cartridge loading and thereby ensuring a perfect synergistic match with any moving coil cartridge. This amplified signal then passes to the specially designed main RIAA phonostage, along a signal path free of the usual relays and coupling capacitors, which again enables a more clean, pure and accurate sound. The signal is then equalized and fed to the balanced XLR outputs. The result? The signal to noise ratio is significantly enhanced, almost matching the headshell-mounted absolute phono's ten decibel improvement.
Engineered With Care:
The absolute phono is built without compromise, incorporating an anti-resonance sandwich construction machined from solid blocks of aluminium and panzerholz wood. The sophisticated power supply, located in a separate chassis, keeps mains interference to a minimum. Hand-selected state-of-the-art nonmagnetic silver Clearaudio Glimmer capacitors positioned at key areas of the circuit further ensure excellent clarity and purity of sound. A single multi-function switch for 'On', 'Off' and 'Mute' modes ensures a sleek finish.
The absolute phono is suitable for all Clearaudio tonearms and is designed to work perfectly with any moving coil cartridge from any manufacturer. This is ensured due to the selected current amplification control which eliminates the need to set the correct load resistance and load capacitance. The optimum operating condition is always set automatically.
