1 Shielded Pair: 20 AWG Audio or Control Bulk Cable - 985'

The Kramer BC-1T-300M is a 985-foot bulk cable configured with one shielded pair of 20 AWG conductors. It is intended for balanced mono audio or control wiring where cable must be measured, routed, cut, and terminated for the requirements of an individual installation. Its clearly defined pair configuration and conductor gauge make it straightforward to match against project documentation that specifies these cable characteristics.

Ideal Use Cases

This cable is suited to installations that call for a single shielded pair rather than a multi-pair cable. Appropriate applications include balanced mono audio connections, point-to-point control wiring, equipment-rack connections, panel wiring, and other custom cable routes that specify 20 AWG conductors. The 985-foot bulk length is particularly useful when a project includes long routes, several shorter routes, or repeated connections that must be cut to different lengths. Compatibility with the intended equipment, connectors, and control system should be confirmed before installation.

Why Choose This Model

BC-1T-300M combines three concrete project-planning details in one product: one shielded pair, 20 AWG conductors, and a 985-foot bulk length. These specifications let installers compare the cable directly with wiring schedules and system requirements without adapting a multi-pair construction to a one-pair circuit. The bulk format also allows each run to be sized for its actual route instead of relying on predetermined cable lengths. This can be useful when cable paths vary between equipment locations.

Installation and Integration

Before cutting the cable, determine the complete route length and include the additional cable required for dressing, service access, and termination. Each run should be identified during installation so that its source, destination, and intended audio or control function remain clear. Terminate the conductors and shield according to the requirements of the connected equipment and the selected connectors or terminal blocks. Maintain the required conductor assignment and polarity throughout the run. The supplied data does not identify the jacket rating, conductor material, shield construction, cable diameter, bend requirements, or supported connector types. Those attributes should be verified when they are relevant to the installation environment or applicable code requirements.

Performance Highlights

The stated one-pair construction is intended for balanced mono audio or control applications, while the 20 AWG designation provides a specific conductor size for system planning. The shielded configuration matches projects that explicitly require a shielded pair. No values are provided for impedance, capacitance, attenuation, resistance, maximum voltage, frequency response, or transmission distance. Performance for a particular system should therefore be evaluated using the requirements of the connected devices and the completed cable run rather than assumptions about unspecified electrical characteristics.

What Makes It Different

The defining feature of this model is its focused cable configuration. It provides one shielded pair in a long bulk length instead of combining several circuits within a multi-pair cable or supplying a finished, fixed-length interconnect. The 985-foot quantity gives an installer flexibility to allocate cable across a project, while the 20 AWG specification supports accurate comparison with designs that call for that gauge. These characteristics make BC-1T-300M a purpose-specific option for documented audio and control wiring plans.

Final Assessment

Kramer BC-1T-300M is a practical match when the installation specification calls for one shielded pair of 20 AWG cable for balanced mono audio or control use. Its 985-foot bulk length supports custom routing and project-specific termination without dictating individual run lengths. Before ordering, confirm that the required jacket properties, environmental rating, shield type, conductor material, electrical values, and termination method are compatible with the project, as those details are not included in the available product data.
