AT-4000 Series Attenuators
2 October 2013
TOA Electronics Pte Ltd launches a series of AT-4000 Attenuators, increasing its product range for volume control suited for the ASEAN market.
The AT-4000 Series Attenuators are designed to be ergonomic with a big-sized control knob to provide a comfortable grip and excellent control with every turn. Finished in gloss white, the series comes in input capacity ratings of 12, 30, 60 and 120 watts which are compliant for most installation types or professional applications. A clip-on face plate also means easy installation and clean overall look, with no visibility of screws on the surface to ruin the visual aspect of the interior space.
Instead of the usual 5 to 6 steps, these are high quality 8-stepped position attenuators, providing a more precision control and gradual volume change of +/-3dB in every step. And besides having the flexibility of a 2, 3, or 4-wire system, the screw-type terminal block allows the use of thick-sized cables (22-14 AWG) commonly used in the region for the rear connection.
The built-in 24VDC override relay feature allows announcements and messages to be sent through to the speakers at the maximum volume during an emergency broadcast. In the event of an emergency paging in a 4-wire connection, the red LED light will serve as an indication that the overriding is in activation.
