| Warranty & Service | 5 years limited on cabinet and drivers; 2 years limited on subwoofer amplifi cation—warranty does not cover misuse, abuse, components upstream from the loudspeaker system, modifi cations or non-factory service. |
| Subwoofer Amplifier | Definition Mk.IV features a built-in subwoofer audio amplifi er. It is a no compromise, state-of-the-art actively fi ltered subwoofer amplifi er that is integrated into the Defi nition Mk.IV loudspeaker cabinet, visible on the rear of the loudspeaker. |
| Subwoofer Amp Type | Class D analog switching amp with heavy-duty traditional power supply. Amplifi er module is Hypex DS4 UcD 400-V5. |
| WARNINGS | RISK OF ELECTRIC SHOCK—THERE ARE NO USER SERVICEABLE OR ADJUSTABLE COMPONENTS INSIDE. |
| Dangerous voltages are present inside case during operation. DC output voltage is 50 volts up and down, 100V DC total. | |
| Also know that the case is sealed and requires technical knowledge to open and should only be serviced by a qualifi ed technician. System is not intended for outdoor use, do not expose to rain or moisture. | |
| RECOMMENDATIONS | We recommended unplugging your loudspeakers, main amplifi er(s) and other regarded electronics during lightning storms or when the playback system will not be used or for an extended period of time. |
| Safety Classification | Class-2, transformer is also a class-2 double wound isolation toroidal transformer that is switched and fused. |
| Safety Standards & Compliance | 60065 | EMC 2004/108/EC | 2006/95/EC | 55103 | RoHS | CE | WEEE | Class-2 subwoofer amplifi er |
| Mains AC Power | 50/60Hz, 115 or 230 volt (transformer is 115/230V wound and factory wired for your region). |
| Mains AC Connection | C13/C14 |
| User Serviceable Fuse | 115V AC mains = 8A | 230V AC mains = 4A |
| Should the fuse blow replace it with an equivalent part. A spare fuse is located within the fuse holder, located just below the power inlet and only accessible when the power cable is not plugged into the inlet. A small fl at blade screwdriver is required. | |

| PEQ Boost | 1/2 octave |
| PEQ Frequency | 20-50Hz |
| Phase | 0-180° // 180°-360° |
| NO BRIDGED MAIN AMPLIFIERS | 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. | |
| Warranty & Service | 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. | |
