Defi nition Mk.IV presents a virtual ground node to the external main amplifi ers’ speaker negative (SP–) output. Bridged
amplifi ers will see this as a short and self protect. Do not use bridged amps to drive Defi nition Mk.IV loudspeakers.
Standard amp types will see an easy 8 ohm load. If main amp does not say BRIDGED there’s nothing to worry about.
2-year limited. Zu recommends factory service. Removing the amplifi er from loudspeaker is simple and will not expose
the user to danger. Loudspeaker may still be operated without amplifi er installed, and with satisfactory results. Though
Zu and Hypex have designed the electronics to the highest standards of fi delity and durability, shit still happens. In the
event that service is required, Zu offers an amplifi er exchange program so you can quickly get your system back up
and running quickly and with minimal hassle.
