Product Description
Features
Tannoy OCV Series pendant loudspeakers deliver the renowned acoustic performance and exceptional value of Tannoy’s CVS Series in-ceiling products in an architecturally sensitive, self-contained, lightweight cylindrical enclosure. Engineered specifically for applications where consistent and high quality audio coverage is required in high or open-ceilinged spaces – such as transport terminus, shopping malls or large double or triple height commercial floors – without compromising clarity, intelligibility and SPL. The unique cylindrical form-factor has been conceived to meet the exacting demands of the architectural sector, minimising the impact on spatial aesthetics and allowing the systems designer to locate the loudspeakers discretely in a manner that won’t conflict with other suspended systems such as lighting fixtures and ventilation. The Tannoy OCV 8 is, by design, a full bandwidth open-ceiling speaker system. The design comprises a 200mm (8.00”) mid bass driver with a coaxially mounted 25mm (1.00”) high frequency section mounted in the cylindrical ABS enclosure with mild steel powder coated grille. The mineral loaded polypropylene cone material and nitrile rubber surround enhance durability and long-term reliability. The OCV 8 is also equipped with a low insertion loss 60W line transformer easily configurable to the following settings via top mounted rotary tapping switch: 70V systems: 60W / 30W / 15W / 7.5W / OFF & low Impedance operation 100V systems: 60W / 30W / 15W / OFF & low Impedance operation The OCV Series is available in either Black or White as standard.

OCV 8 // issue 1.04 // 22.11.11
OCV 8 Architectural specifications The self-contained, suspended open-ceiling loudspeaker shall consist of a 200 mm (8.0”) mineral loaded mid bass driver with coaxially mounted 25 mm (1.0”) high frequency unit and passive frequency dividing network mounted in a vented, cylindrical enclosure with mild steel powder coated grille. The cylindrical chassis shall be constructed of steel. A standard euroblock connector shall be integrated into the top plate of the enclosure providing audio connection. Suspension of the device is achieved through a steel cable locator arch on the top plate of the enclosure, engineered to take in excess of total weight of device. Steel wire and ‘Gripple’ locking wire connectors are supplied for suspending at desired height from approved ceiling-mounted hang point. Performance of the suspended open-ceiling speaker shall meet or exceed the following criteria: The system shall have a conical coverage pattern of 80 degrees (1 kHz to 6 kHz). Frequency response measured on axis shall be 80 Hz – 20 kHz (-10 dB) from rated sensitivity, measured in an IEC baffle in an anechoic chamber) with no equalization. Sensitivity shall be 90 dB (1 W @ 1 m). Long term average power handling capacity as defined in EIA-426B test shall be 60 W, recommended amplifier (program) power 140 W. The nominal system impedance shall be 16 Ohms (in low impedance setting). The open-ceiling speaker system shall be equipped with an integrated 60 W high performance line transformer for use in 70.7 or 100 Volt distributed audio systems with 60, 30, 15, 7.5* Watt and OFF taps available. An easily accessible rotary switch located on the top panel (adjacent to euroblock connector) shall be available for selecting transformer and low impedance settings. A weather resistant rubber weather booth shall provide protection for the euroblock connection and tapping switch. The diameter of the enclosure shall not exceed 302 mm (11.89”), overall depth from the top of the enclosure to the bottom shall not exceed 492.5 mm (19.39”). The total weight of the device shall not exceed 7.8 kg (17.2 lbs). The device shall be available in black or white finish as standard. The self-contained, suspended open-ceiling loudspeaker system shall be the…..OCV 8. *70 Volt only
