Mixer amplifiers, pro amplifiers and rack peripherals for 100V line systems and installed sound: pre-amps, zone selectors, timers and matrix units.
EASTVO manufactures 55 models in this range. Specifications below are the ones specified most often on tenders; full data sheets are available per model. For a project point schedule, send a floor plan to [email protected].
A mixer amplifier has the pre-amplifier, the mixing and often the zone selection built in, so microphones and line sources connect straight to it. A pro amplifier is a power stage only, used where a separate pre-amplifier or matrix already handles routing and level.
Size it on the sum of the speaker tap wattages, with headroom left for points added later. Every amplifier in the range drives a 100V line, and the rack peripherals add zone selection, timing and matrix routing on top of that power stage.
Pre-amplifiers, zone selectors, timers and matrix units — the parts that sit between the sources and the power amplifiers in a rack build. They are what turns a set of amplifiers into a system with zones, schedules and priority.
Yes. A timer or matrix unit holds the schedule, so lesson bells, shift changes and background music run without an operator. Live paging from a microphone still takes priority over anything scheduled.
Yes, and it is a common upgrade path. A 100V line amplifier keeps existing analogue zones working while SIP speakers cover new buildings, and both can be triggered from the same console or the same alarm signal.
