EV UW30 Underwater Speaker for Marine Biology


UW30 underwater transducer

The UW30 underwater speaker is an economical moving-coil underwater speaker manufactured by Electrovoice. This unit produces very low sound levels, and is only recommended for marine biology experiments and sound in samadhi tanks. DO NOT USE THE UW30 IN LAP SWIMMING POOLS  -- THE SOUND LEVEL IS MUCH TOO WEAK. (For lap swimming applications, use only the Lubell 9484 piezoelectric speaker, which produces 30dB higher sound levels equaling over 100+ UW30 speakers!!!) The UW30 underwater loudspeaker may be used in tropical to arctic climates in freshwater or saltwater by virtue of its ABS shell and SJEOOW thermoplastic cable (rated -50C - 105C). The UW30 is rated at 30 watts at 8 ohms, and is fitted with a 50' cable.

For permanent in-wall installation during new pool construction, the UW30 must be mounted in a metal forming shell the front of which is enclosed by a captive metal screen (see UW30N/G below in accessories) which is bonded to and secured to the forming shell which ensures a low-resistance contact. This is a legal requirement found in the 2005 NFPA 70 Handbook National Electrical Code NEC 680.27, as well as the 2003 International Residential Code IRC E4106.9.1.  Plastic niches and grilles may NOT be used for any underwater speaker under any condition. In addition, the underwater speaker must be powered by an amplifier having a grounded power cord, UL Commercial Sound label, Class 2 wiring label, and transformer isolated Speaker Output not exceeding UW30 speaker's 30 watt 8 ohm rating (15.49 volts rms). For single speaker installation, we recommend connecting the UW30 to the 8 ohm and common terminals of the Peavey UMA352 amplifier and to pool ground using wiring diagram and components listed in the UW30 manual. For dual speaker installation, we recommend connecting the UW30 speakers in parallel to the 4 ohm and ground terminals of the Peavey UMA752 amplifier and to pool ground using wiring diagram and components listed in the UW30 manual. Speaker, niche, grille, and amplifiers are listed in the ACCESSORY section below at the guaranteed lowest cost.

For portable swimming pool recall & sound system, the UW30 is provided with a self-contained Anchor Megavox Pro sound system (see "Accessories" below), integrating rechargeable battery for safety and convenience. The Megavox includes a microphone for coaching swimmers above or below the water. The Megavox includes a warning siren system for recalling swimmers above or below the water in the event of an approaching storm. The Megavox even has a connector for attaching an iPod * so music can be heard by swimmers above or below the water.

For talking to and listening to dolphins and whales, the UW30 is provided with a Speco PAT-20TB mobile amplifier (see "Accessories" below), which installs on boat dash via suction cups, then connects to available cigarette lighter socket.
Service: The UW30 has a 5 year limited warranty against manufacturers defects, such as water entry. Warranty does not cover repair or replacement of a burned out speaker, which is a likely scenario if the fuse and resistor circuit in the owners manual is not followed and an amplifier greater than 30 watts is used. To have a unit evaluated for repair, please return prepaid and insured to Telex/EV Service Dept., #1 Telex Dr., Morrilton, AR 72110. Be sure to package securely, and include a copy of your sales invoice from Lubell Labs, along with your contact information and a description of the problem you are having.
