Formula Sound Sentry Mk2

With the strict noise regulations in force today no-one can afford to contravene the noise levels laid down by the local governing body. The Sentry, designed and manufactured by Formula Sound, is a product which will help solve some of the environmental noise problems encountered in entertainment venues and industry today.

The Sentry has connectors provided to interface with a range of equipment, plus internally selectable options to make the system as versatile as possible. Although its main application is to control mains power outlets in entertainment venues it is not restricted to this application. Basically any function that can be controlled by a relay or switch can be controlled by the Sentry. These may include disconnecting loudspeakers, switching passive attenuators to reduce system volume or acting as the trigger into an active attenuator system. It is microphone driven and has its own microphone built in to minimise tampering.

The Sentry also incorporates the facility to operate at two different sound level thresholds which may be selected manually, by a remote key switch or similar, or automatically by a time switch (not supplied). This allows a venue to operate at different levels at different periods of the day. e.g. when near offices or shops. An integral timer is available as a cost option.

New features on the Mk2 version:

• New case design provides easier connections via cable entry knock-outs and screw terminals.
• A choice of internal microphone (supplied factory fitted as standard) or external microphone.
• Removable cover provides access to all connections and settings. Anti-tamper seals are provided.
• Anti-tamper microphone circuitry is incorporated with a front panel indicator.
• Dual mains voltage operation is standard (internally switchable).
• Provision to connect a security loop is provided. This may be required to detect open doors or windows that would impair the sound proofing of a building, etc.
