The V2000 Voice Alarm Amplifier Mainframe works with the VIPEDIA-12, D-Series amplifiers and the LSZDC interface card to provide amplification and monitoring for Public Address, Voice Alarm and Commercial Audio loudspeaker systems. The mainframe provides the housing, control, and power supplies for up to ten ASL D-Series power amplifier modules in a 2U enclosure.
An integrated EN54- 4 compliant battery charger interfaces to ASL’s BPC65-BAT battery supply through the BDIST-V2000, and provides enough current to charge the battery system system for a fully loaded 2000W system, including one VIPEDIA- 12.
Integrated EN54-16 certified Voice Alarm amplification and EN54-4 certified battery charging reduces build time, and simplifies delivery of compliant Voice Alarm systems.
By combining high efficiency during broadcasts with ultra-low power consumption during quiet periods, the V2000 greatly reduces the costs and CO2 emissions associated with powering the Voice Alarm system cooling in the rooms in which they are installed.
By setting the maximum power of each amplifier module, intelligent configuration enables the most efficient use of each frame’s 2000W power supply.
D150 and D500 class-D transformerless amplifiers are compatible with the V2000 amplifier mainframe and LSZDC dual line surveillance interface modules. Each amplifier supports:
The configurable output power capability of the D500 and D150 amplifier modules enables reduced mainframe count, lower quiescent power requirement, and improved environmental performance compared with traditional amplifier designs.
The LSZDC is an amplifier interface card for use with the D500 and D150 Transformerless Class-D Amplifiers. It enables two circuits (A&B) to be fed from a single amplifier.
The interface card provides:
Relays in series with each output facilitate isolation of faulty speaker circuits. Loudspeaker circuits can be monitored using DC, Impedance or Loop Return methods. Each LSZDC includes powerful on-board DSP (digital signal processing) capability, enabling parametric equalisation, gate and gain settings to be applied separately to each amplifier.
