From Westminster Lab
The Omne puts 50W per channel of Class A power into 8 ohms, 100W into 4 and 200W into 2, with 12A of peak current behind it. The circuit is fully balanced and symmetrical.
Westminster Lab matches its output transistors to within 1%, and checks that match at several working points along each device's curve. Then every matched set runs under heavy load for hours before it goes in. The company credits that process for fitting 50W of Class A into one 35kg chassis.
Sources connect through 3 balanced XLR inputs, with 2 slots for optional modules. A balanced XLR pre-out lets you add a power amp later. Volume runs in 99 steps across 63dB, and speakers connect through WBT nextgen terminals.
