The lightweight, switched-mode power supply auto-ranges to global mains voltages from 100 to 240V 50/60Hz. Power Factor
Correction smooth’s out the mains current draw over the whole of the AC waveform, effectively reducing cable losses caused by
high peak currents in the mains distribution system.
The module features advanced monitoring and protection, including over-temperature power limiting, short-circuit and overload
protection. Amplifier monitoring via U-NET™ includes input signal, output signal at the drive unit terminals, limiter status,
heatsink temperatures and fault conditions.
The amplifier section is designed to withstand the various environmental conditions typically found in live sound applications –
such as rain and ambient temperatures of up to 45°C. A sophisticated cooling arrangement, where air is forced over the
amplifiers’ heatsinks through a metal tunnel, employs an IP rated fan with intelligent drive for quiet operation when the system
is used at lower powers.
Connections
The amplifier and network module housed in the rear of the cabinet is protected by a weatherproof canvas cowl. This vital
accessory has two functions. In the event of poor weather it will keep all electrical connections dry. In the event of very hot
weather it acts as a sun shade to keep direct sunlight off the amplifier cooling system and thus prevents over-heating.
The cowl travels folded flat for ease of transportation. It is held in the operating position by two triangles of canvas mounted
towards the middle of the cowl. These have straps attached and by pulling the straps the cowl pops up into position and is held
in place with the two supporting triangles which connect to the inside of the cowl using Velcro. To fold the cowl flat, the straps
are again used to pull the supporting triangles down left and right.
