 One Clever little box zone selector switching unit. Manufacturer spec:The ZSU-5A zone selector switching unit provides the facility to take a high impedence 100v loud speaker output from an amp and split in into 5 separate zones.Each Zone can be selected using either voltage-free contacts or ideally a multi-zone paging microphone.As well as zoning capability, the ZSU-5A will also provide a switched 24v DC output and a voltage-free relay contact active whilst the unit is in use.Ideal for small to medium sized commercial audio installations, units can also be linked to provide and meet larger system requirements.ZSU-5 Key Features:5 Zone and All-Call Switched 24V DC Output Powdered Coated Steel Case Screened metal enclosure Spare relay contacts AC 230V/ DC 24 V Powered Dimensions(mm): 162 x 220 x 44 (H x W x D) Weight 1.8kgFrom the web: ZSU-5 Zone Switching UnitPrimarily intended for the switching of 100V line loudspeaker feeds, this may be used for many other tasks, including special intercom or cue-feed systems. There are five individual balanced inputs to switching relays, fed out to five zone outputs, perhaps supplying background music or show-relay, until a contact-closure is applied to any of the five associated control pairs. Each of these causes the relay concerned to change over to a sixth input, bussed to all five relays, perhaps carrying paging or talkback. All-Call control input switches all five relays simultaneously. Two microphones or other devices, such as pre-amplifiers, may be looped-in and out of the unit, to supply them with phantom power at either 10V or 24V, for use where such power is unavailable from the amplifiers in the system. A further relay may be jumpered to mute the first of these, and has a slow release, to avoid unwanted artifacts, and spare contacts. Up to 100mA at 24V DC is available from the inbuilt PSU for driving other equipment such as relays and indicator lights. Mains operation (230V), or 24V DC. Dimensions: 245(l) 185(w) 52(h)mm. Weight 1.7kg.
