  • Overview

    Purpose-Designed Extension for CBT 70J-1 Line Array Column Speaker

    When connected to a CBT 70J-1 line array column speaker, the CBT 70JE-1 Extension provides extended bass response, extended pattern control, and increased sound output levels. The combined array system provides Constant Beamwidth Technology™, which represents a breakthrough in pattern control consistency, utilizing complex analog beamforming and amplitude tapering to accomplish superior, consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of passive column speakers.

    Product Highlights:

    Components: Four 125 mm (5 in) high-power LF drivers

    500 Watt power handling

    Built-in purpose-designed crossover network, for

    combining with CBT 70J-1

    Coupler plate included

    Product Features:

    Applications

    The superior sound quality, excellent pattern control, asymmetrical vertical coverage and compact design makes the CBT 70J-1 + 70JE-1 System ideal for applications such as performance spaces, lecture halls, classrooms, A/V, transit centers, school stadiums, multipurpose spaces, racetracks, theme parks, and fill applications, among many others.

    Adjustable Coverage to Fit the Application

    The innovative coverage adjustability of the CBT 70J-1 + 70JE-1 System allows switching between broad and narrow vertical coverage settings to allow matching the coverage and throw requirements of the application. Coverage can be easily switched in-venue with the speaker already installed. This innovation allows a single loudspeaker system to excel in a wide range of project types.

    User Variable Voicing

    The voicing of the CBT 70J-1 + 70JE-1 System can be set to match the application through a Music/Speech switch. The Music setting provides flat frequency response, while the Speech setting produces a mid-range presence boost to provide clear, intelligible speech, along with increased midrange sensitivity for higher midrange maximum output capability.

    SonicGuard™

    Dynamic SonicGuard protection of the CBT 70J-1 + 70JE-1 System (built into the CBT 70J-1) protects the high frequency section, minimizing distortion at high drive levels by limiting driver excursion dynamically. This maximizes music clarity and speech intelligibility at high drive levels while protecting the drivers from damage due to occasional overpowering.

    Bracketry

    A thick coupler plate for connecting the CBT 70J-1 + 70JE-1 end-to-end is included with the 70JE-1. The CBT 70J-1 + 70JE-1 System can utilize the swivel (pan) / tilt wall bracket that is included with the 70J-1, or can utilize industry-standard mounting points on the coupler plate (OmniMount™ 60.0 and 120.0 patterns) for attaching to a wall. Alternatively, the M6 inserts on the back panel can be utilized to suspend the speaker using forged shoulder steel eyebolts or swivel mounting rings, providing installation versatility.
