Control Monitor Loudspeaker System

\- Control Series

Key Features: b High sensitivity (90 dB SPL,

2.83V@ 1 m)

b Tapped, switchable autotransformer for use on 100 V lines may be bypassed

F High power handling (150 W continuous pink noise with autotransformer bypassed) with internal protection network

F Molded enclosure with shielded magnetic structures

b Accepts all Control 1 optional MTC mounting hardware

Sound system installers have used many thousands of JBL Control 1 loudspeakers in restaurants, clubs, discotheques, shopping centers, and other locations where multiple loudspeaker systems are driven by a common source. The JBL Control 1AT

- is designed to simplify installation of multiple systems in these environments.

The Control 1AT features the acclaimed acoustical performance of the Control 1 and adds to it a high quality internal autotransformer which allows easy connection to a constant-voltage loudspeaker distri- bution line. The autotransformer may be set to 7.5,15,30 or 60 watts when fed from a 100 volt line, and it can be bypassed to connect the system directly to the power amplifier. The autoformer switch is mounted on the rear of the enclosure exterior and is screwdriver adjusted.

b Control@ lAT Control Monitor Loudspeaker System

The JBL Control IAT has the same magnetically shielded 135 mm (5% in) low frequency and 19 mm (% in) high frequency drivers as the Control 1, so it can be mounted in close proximity to video monitors without interference with the picture. It features the same high power handling (150 W continuous pink noise), high sensitivity (90 dB SPL, 2.83 Vat 1 m), excellent frequency response (120 Hz - 20 kHz + 3 dB), internal protection network, and molded enclosure design, and it accepts all Control 1 optional MTC mounting accessories.

For monitor sound quality, easy and unobtrusive instal- lation, and long, reliable life, the JBL Control 1AT is without equal.
