Product details

Fezz Ovo is a stereo valve headphone amplifier with a single-ended Class A triode output stage. Two EL84 valves and one 12AX7 valve form the amplification circuit, with automatic bias adjustment and selectable load ranges for headphones from sixteen to six hundred ohms.

Headphone outputs and operating conditions

The front panel provides 6.35 mm jack, four-pin XLR and 4.4 mm Pentaconn headphone sockets. A Low/Mid/High impedance selector helps match the connected headphones. Fezz rates output at 1,500 milliwatts with two percent THD and specifies a 16 Hz–120 kHz bandwidth at minus three decibels into a 32-ohm load; the bandwidth condition is separate from the output-power rating.

Source connections and optional control

RCA and XLR line inputs connect compatible analogue source components. Rear RCA and XLR signal outputs provide onward analogue connections. The optional plug-in Bluetooth board adds wireless reception, and an optional remote provides convenient operation. Seven Evolution enclosure finishes complement different system styles.
