The V400 amplifier mainframe, together with M-Series amplifiers and the LSDDC interface card, provides amplification and monitoring for Public Address and Voice Alarm loudspeaker systems.

The mainframe provides the housing, control, and power supplies for up to four ASL M-Series power amplifier modules in a 2U enclosure, and is compatible with both VAR and VIPEDIA-12 routers.

EN54 Certification

Fifteen years of class-leading high reliability products combined with EN54-16 and LPCB certification ensures peace of mind in life safety applications.

Maintenance Friendly

Amplifiers can be replaced on-site without needing to disconnect any cables or remove the frame from the rack. Simply remove the front panel, slide out the module and replace with a spare.

Eco Friendly

ASL’s innovative Adaptive Class-D technology is so effective at reducing off load power consumption that battery backup systems are reduced and amplifiers run fan-free.

 

ASSOCIATED HARDWARE

LSDDC

The LSDDC is an amplifier interface card for use with the M100, M200 and M400 Class-D Amplifiers in a V400 Amplifier Mainframe for Voice Alarm and Public Address applications. Uniquely, it enables two circuits (A&B) to be fed from a single amplifier while still maintaining BS5839 Pt 8 compliance.

This interface card provides; amplifier health monitoring via subsonic surveillance tone, automatic control of changeover to standby amplifier, loudspeaker line earth leakage monitoring, and loudspeaker line ‘End Of Line’ (EOL) monitoring. Relays in series with each output facilitate isolation of faulty speaker circuits.

The unit also supports a secondary audio input that enables emergency sources to be switched directly to the input of the power amplifiers.

A second mode of operation allows loop return monitoring to be implemented or a single loudspeaker circuit can be fed instead of two, if required.

 

M100 Amplifier Module

The M100 is one of a range of high efficiency Class-D Amplifiers for Public Address and Voice Evacuation applications. The amplifier is housed in a V400 Amplifier Mainframe. The M100 will deliver 100 W to a 100 V loudspeaker line, even with the Amplifier Mainframe’s 230 V mains supply absent and right down to a 21 V battery supply voltage.

 

M200 Amplifier Module

The M200 is one of a range of high efficiency Class-D Amplifiers for Public Address and Voice Evacuation applications. The amplifier is housed in a V400 Amplifier Mainframe. The M100 will deliver 100 W to a 100 V loudspeaker line, even with the Amplifier Mainframe’s 230 V mains supply absent and right down to a 21 V battery supply voltage.

 

M400 Amplifier Module

The M400 is one of a range of high efficiency Class-D Amplifiers for Public Address and Voice Evacuation applications. The amplifier is housed in a V400 Amplifier Mainframe. The M100 will deliver 200 W to a 100 V loudspeaker line, even with the Amplifier Mainframe’s 230 V mains supply absent and right down to a 21 V battery supply voltage.

 

SSINT

The SSINT is an amplifier interface card for use with ‘standby’ M100, M200 and M400 Class D Amplifiers in a V400 Amplifier Mainframe for Voice Alarm and Public Address applications.

This interface card provides monitoring of a standby amplifier in the V400 mainframe. In the event of a failure of an ‘active’ amplifier driven by a connected LSDDC interface this unit will automatically switch to powering the affected zone from the standby amplifier.
