The output jack is designed for standard 1/4 inch/6.35mm headphone plugs (B-gauge) and can also be used with tapered A-gauge plugs. Headphones of impedance 8 - 2,000 Ohms may be used but best results will be obtained with impedances of 16 - 600 Ohms. An impedance reduction network reduces the driving impedance "seen" by the headphones and compensates for the headphone's cable capacitance, leading to a more focused musical image than purely resistive or power-amp configuration headphone amplifier outputs. It also reduces the apparent differences between dissimilar headphones.

The Novo is supplied with an Energy Efficient plug style AC/DC mains adapter power supply for universal mains use: 90-250V ac; supplied with a selection of plug heads to suit the customer's mains outlet. The power supply is of the switched mode type and sensitive users may detect a slight tingling sensation from the Novo case: this is normal and within world safety standards, but can be eliminated completely by connecting a wire to the Novo "aux ground" post; the other end to earth (either mains earth or an earth spike - seek qualified assistance if unsure). When connected to an earthed source this wire will not normally be required. The switched mode power supply emits an ultra-sonic whistle which cannot normally be heard, but in the presence of other persistent noise (such as air-con, refrigerators etc) a beat frequency (chirping) may be heard. Careful positioning will minimise this effect.

A Chained set of phono/RCA jacks enables the stereo input to be routed to other equipment such as a power amplifier. The input impedance is greater than 39 kilo Ohms so as to be virtually transparent to the source.

The volume control can be set at any position to give comfortable listening. Unlike Hi-Fi amplifier volume controls, it can be set at any position and still give excellent performance. This is preferable to the contact resistance and wear of a gain switch, which would otherwise be required.
