VM-2240 System Management Amplifier

Features

• Versatile inputs provided include a remote microphone input, three microphones/line inputs, two background music inputs as well as a telephone paging input.
• Every input can be balanced with the exception of the BGM inputs. An isolation transformer is optionally available. The balanced configuration helps ensure a system with high resistance to external noise pickup.
• The microphone/line input and the BGM input channels are equipped with individual low and high-frequency controls for desired tonal adjustment.
• Built-in top priority is automatically assigned to emergency broadcasts at all times. For general announcements made using INPUT numbers 1-3, BGM is automatically muted during the announcement. Broadcast priorities can be set for each input.
• In addition to the six standard chimes, a custom chime tone from the optional EV-200M Voice Announcement Board can be combined with announcements.
• The BGM input, as well as INPUT numbers 1-3, allow setting the volume level for each zone. If an emergency announcement or all call paging is required, the master volume control and zone volume controls are bypassed to ensure the broadcast is effectively heard throughout the zone or zones.
• Three- or four-wire speaker line control is possible. Emergency broadcasts and all calls paging can be made even while the local the attenuator is turned down.
• For local systems used for non-emergency applications, broadcasts may be interrupted by control signals from the emergency master system. Local speakers can then also be utilized as master system speakers.
• The distributed speaker line can handle a 100V (standard), 70V or 50V speaker distribution system by reconfiguring the unit’s internal wiring.
• Power turns on/off can be remotely activated from external equipment. If using the amplifiers as local amplifiers, power can be turned on or off by control signals sent from the master system.
