Cambridge Audio Announce Two Phonostages
Cambridge Audio have announced two new phono stages, the Solo and the Duo.
The Solo and Duo both use switch mode power supplies and surface mount technology to allow a compact overall design with short signal paths on the board inside.
Both phono stages automatically switch to standby if unused for twenty minutes; with a standby energy consumption of less than half a watt.
The Solo is a dedicated moving magnet phono stage, whilst the Duo will work with any turntable thanks to incorporating both moving magnet and moving coil input stages.
The Duo combines the phono stage with a dedicated headphone amplifier and volume control, allowing consumers the opportunity to enjoy their turntable without the need to switch on their main amplifier.
Both phono stages feature a rear mounted balance control to trim channel level imbalances in cartridges. Solo has a simple fascia with just an LED indicator while Duo adds a full size 6.3mm headphone jack and volume control.
Solo: £149.99 Duo : £249.99
