To complete the Choral series, Chord have updated their long standing, high performance phono stage, using the latest high frequency power supply technology along with many key NEW features, to bring the performance levels and aesthetic style in line with the rest of the range. The Symphonic offers an almost infinite number of input impedance and gain options as well as balanced and unbalanced input option to the cartridge, all externally selectable, with selections signified internally with illuminating LEDs. Also incorporated in the design, is a new low frequency Rumble filter. This device uniquely filters out rumble signals appearing on both channels. The Symphonic has been designed for Moving Coil cartridges only.
The Symphonic Phono stage conforms to the RIAA curve without the IEC roll-off when the Rumble filter is set to off. This is commensurate with the high calibre of Chord amplification. The IEC curve response can be added by setting the Rumble filter to on.
According to the wiring of the tone arm on the record deck used, the Symphonic can be operated in either an unbalanced or balanced mode. All domestic equipment is designed to enable unbalanced operation. Better results will be achieved in balanced operation when used in a complete Chord system.
