RapcoHorizon SL-2 Direct Box

Professional Direct Box for Clean Signal Conversion
The RapcoHorizon SL-2 Passive Direct Box is a professional-grade solution designed to convert high-impedance instrument or line-level signals into balanced, low-impedance outputs suitable for direct connection to a mixing console or recording interface. Built with simplicity and reliability in mind, the SL-2 ensures consistent, noise-free operation across a wide range of live and studio environments. Whether you're running a guitar, bass, keyboard, or line-level source, this unit delivers clean signal transfer without unwanted hum or distortion.

Versatile Input and Output Configuration for Maximum Flexibility
Equipped with dual 1/4" input and loop-through jacks, the SL-2 allows you to connect your instrument or audio source while maintaining an unaltered signal path to an amplifier or additional equipment. This setup makes it ideal for musicians who want to monitor their tone on stage while sending a balanced signal to the front-of-house or recording console. The XLR male output provides a professional-grade balanced connection for long cable runs, ensuring minimal signal degradation in any audio environment.

Precision Signal Control with Built-In Pad and Ground Lift Switches
The SL-2 features a -20dB pad switch that allows users to handle both instrument and line-level sources without overdriving the mixer’s input. This feature ensures a clean, distortion-free signal even when using high-output instruments or active electronics. Additionally, a ground lift switch eliminates unwanted ground loop hum, making it perfect for complex live sound setups or studio systems where multiple devices share the same power source.

Durable Construction Built for Professional Use
Housed in a rugged steel chassis, the SL-2 is built to withstand the demands of live performance and frequent transport. Its compact design and durable components make it a reliable choice for touring musicians, sound engineers, and AV technicians. The high-quality IMT-1 transformer ensures electrical isolation between input and output, providing superior noise rejection and maintaining the integrity of your sound.

Ideal for Stage and Studio Applications
From live stage performances to recording sessions, the SL-2 offers the versatility needed in any professional audio setup. It’s particularly effective for instruments with passive pickups, keyboards, or other unbalanced sources requiring a clear and consistent signal to the mixing desk. Its straightforward design makes it an essential piece of equipment for both beginners and professionals seeking a reliable direct box solution.

Compact Size for Convenient Integration
Measuring approximately 3 ¾" wide by 5" high by 1 ⅞" deep, the SL-2 easily fits into any stage rig, pedalboard, or studio rack. Its small footprint allows for easy transport and integration without cluttering your setup, making it ideal for mobile sound systems or compact performance rigs.
