Public Address Paging System for Hazardous Environment Applications

This hazardous and combustible environment public address sound system with wide angled horns is designed to operate safely in hazardous areas such as oil, gas and petrochemical industry applications that require high-efficiency voice communications and the ability to record and playback sounds produced from a microphone, CD player or other sources. This system comes with 24 explosion-proof Atlas Sound HLE/MLE-30 horns and MLE-3T drivers, an Ashly Audio Pema 8125.70 8-channel power amplifier with Protea DSP, a TOA EV-20RPS digital message repeater that can hold up to four messages, whether it's for breaks or safety reminders, a TOA PM-660U PTT paging microphone and all the cables needed to get your system up and running.

Atlas Sound HLE/MLE-30 UL Listed Explosion-Proof Wide Angle Horns

Model HLE/MLE-30 is a high-quality, polycarbonate projector that creates a 120° x 60° pattern for wide area coverage. Use with HLE/MLE explosion-proof compression driver/horn assemblies to provide engineered, high-efficiency voice and electronic signal communication in hazardous areas. Only the HLE/MLE-30 and the HLE/MLE-32 Horns are UL Listed for use with the HLE or MLE Line of Explosion Proof Drivers.

Atlas Sound MLE-3T UL Listed Explosion-Proof Drivers

The MLE-3T is an explosion proof compression driver for horn assembly and is designed for use in hazardous areas of high-efficiency voice communications and electronic signals. Driver protection in a solid aluminum die-cast housing, the rated power 30W. The model is equipped with 0.50" conduit and an adjustable mounting bracket. HLE/MLE-30 and HLE/MLE-32 horn are UL listed and are used with HLE or MLE Series explosion-proof compression drivers.

Ashly Audio Pema 8125.70 Power Amplifier with Protea DSP

The Ashly Pema 8125.70 powered digital signal processor consists of 8 inputs and 8 power amplifier outputs with the ability to assign any input to any output. Each input channel includes a summed stereo (RCA, +11dB maximum) and mic/line gain stage (3-pin Euroblock, +21dB maximum) capable of 0, +20dB, +40dB, and +60dB of gain with +15V phantom power when selected. Summed stereo input impedance is 3.16k Ohms unbalanced and the mic/line input impedance is 4.8k Ohms active balanced. Channel one includes a transformer-isolated TEL-PBX select. Each input and output has an individual mute capability. Each input and output also has six processing blocks, configurable for Dynamics (ambient noise compensation, compressor/limiter, auto-leveler, ducker, gate), Gain (including Group VCA and remote gain), Equalization (FIR filters, 31-band graphic, parametric x 10, feedback suppressor), Crossover, Delay, Metering, and Signal Generator (sine wave, pink noise, white noise). The routing stage allows the user to assign an input to any or a combination of outputs and separately adjusts how much signal level goes to each output (matrix mixer). The matrix mixer also has selectable gain-sharing automatic mixing capability. Each input stage has an additional preamp output (post DSP) on the back panel (3-pin Euroblock). Eight powered outputs deliver 125W @ 70V (7.62mm Euroblock), and channel pairs can be bridged for 250W @ 240V. Frequency response is ±1dB 20Hz to 20kHz. Signal-to-Noise is greater than 102dB, 20Hz – 20kHz unweighted. LED indicators show signal level (-18, -12, -6), clip/mute, bridge, over temperature and over current conditions. Output levels can be adjusted by the front panel volume controls when enabled.

TOA EV-20RPS Digital Message Repeater

The TOA EV-20R digital message repeater with USB connection is a convenient addition to sites where the same message or music can be repeatedly broadcasted. Up to 4 types of music and/or messages with a total of 6 minutes time can be recorded and played back. The USB port facilitates recording by transferring the supplied sound sources from a PC to the unit. The unit's small built-in amplifier enables small-scale broadcasts through a simple speaker connection. The EV-20R Sound Repeater is used to record and play back sounds produced from a microphone, CD player or other sources. Its particularly ideal applications include repeated broadcasts of the same message in schools, department stores and factories. Flash memory is used as a recording medium, and up to 4 different messages can be recorded and played back. The Sound Repeater also permits broadcasts to be made directly from the microphone or CD player without recording.

TOA PM-660U Desktop PTT Paging Microphone

TOA’s PM-660U is an elegantly styled, compact desk microphone for use in public address, paging and radio communication systems. Ideal applications include restaurants, offices, warehouses, transportation terminals, dispatch centers and entertainment facilities. Its smooth, natural response provides high quality voice reproduction and excellent articulation to enhance the overall performance of your system. Compact and lightweight, the PM-660U requires a minimum of desk or counter space and is easy to handle. To significantly reduce background noise and feed-back, the PM-660U features a cardioid pick-up pattern that is uniform over the entire frequency range. The dynamic microphone element has a 600 ohm balanced output and the microphone is supplied with an attached 8.2’, four-conductor cable with stripped wire ends. Two conductors are shielded and are dedicated for the microphone signal. The other two unshielded conductors connect to an auxiliary, normally-open switch contact, used to activate external muting, priority or relay control circuits. The auxiliary switch contact is closed by using the push-to-talk bar, which also turns on the microphone by opening a second set of contacts that normally short the mic element. A locking lever is provided to keep the push-to-talk bar in the "on" position when the microphone must be kept open for an extended period. A wire mesh grille protects the mic element and incorporates an internal windscreen to reduce popping noises from speech. Ideal for desktop or shelf mounting, the integral microphone stand/base is fitted with four, rubber isolated feet to reduce mechanical noise pick-up. Constructed of high impact ABS resin, the microphone is finished in a neutral dark gray with a prominent, orange push-to-talk button.
