The Symphonic offers an almost infinite number of input impedance and gain options as well as balanced and unbalanced input options to the cartridge, making it a highly flexible device for integrating high-quality turntables into Chord systems. The comprehensive settings options are all externally selectable, with selections signified internally with illuminating LEDs.

A rumble filter removes unwanted low-frequency rumble signals appearing on both channels. The Symphonic Phono stage conforms to the RIAA curve without the IEC roll-off when the Rumble filter is set to ‘off’ Preamps: CPA 2500, CPA 3000, CPA 5000, and CPA 8000. Preamps: CPA 2500, CPA 3000, CPA 5000, and CPA 8000.; 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 turntable used, the Symphonic can be operated in either an unbalanced or balanced mode.
