The J48 is a high performance active direct box for live concert touring and professional recording studio applications, with the ability to handle extreme transients without distortion while delivering the natural sound of your instrument.

• Exceptional headroom & dynamic range
• Retains the natural sound of the instrument
• Merge switch sums stereo instruments to mono
• Powered by 48V phantom, no batteries required

Higher Rail Voltage, Higher Headroom

Most battery-powered guitars and basses will produce as much as 7 Volts when played at maximum volume, which can easily overload typical active direct boxes which have are only able to handle about 3 Volts. The J48 uses a unique switching power supply that raises the internal rail voltage so it can handle up to an incredible 9 Volts, resulting in improved signal handling and greater headroom. This additional headroom significantly reduces distortion of all types, allowing the natural tone and character of the instrument to shine through.

The Radial J48 has gained a tremendous following through the professional audio community. With significantly more headroom, lower distortion and unmatched durability, it is no wonder that the J48 has become the most specified direct box on stages around the world. As you will note with the specifications below, the J48 is exceptionally linear when tested both under laboratory conditions and when placed under the extra stress of 100 meters (300 feet) of cable. In the lab, the high frequency response actually exceeds 40kHz! This makes the J48 a perfect candidate for the most demanding studio recording while being the obvious choice for the artist on stage.

The Radial StageBug SB-5 is a compact & portable stereo direct box designed to accommodate laptop computers, tablets, and other consumer audio products when amplifying the signal through a PA system.

• Stereo direct box for laptops, smartphones, and tablets
• Cable with 3.5mm stereo plug to connect to mobile devices
• Transformer isolation eliminates hum and buzz
• Plug & play easy to use, no power required
• Compact design fits in your laptop bag

The easy way to connect to the PA

The StageBug SB-5 provides an easy to use professional interface for connecting any mobile playback device to a mixer or PA system, with a built-in cable and 3.5mm stereo plug to connect directly to your laptop, smartphone, or tablet. Inside, a pair of custom wound transformers isolate the signals to prevent hum and buzz, and balance the audio to feed long cable runs without noise. Left and right 1/4" TRS outputs are provided for stereo operation, or a mono XLR output can be used to save channels on the PA system. The SB-5 works without any power required, and features additional ground lift and pad switches to eliminate ground loop noise and prevent distortion from high output audio sources.

The Radial Stage Bug SB-5 Laptop is a stereo direct box designed to easily integrate with laptop computers and other audio sources that employ a mini 3.6mm (1/8″ TRS) connector. It features an integral cable and storage cleat for easy deployment. inside, the passive design features two custom transformers that perform the balancing and impedance conversion. Transformer isolation benefits by eliminating hum and buzz caused by ground loops. Although remarkably compact and affordable, the SB-5 produces a exceptionally linear response with almost zero phase shift and less than 0.2% distortion at all frequencies. This makes the Stage Bug SB-5 an excellent choice for audio playback via PA systems, audio-visual integration and portable DJ setups.

The USB-Pro is a high-resolution stereo digital audio converter and direct box that is designed to connect to any computer and seamlessly convert digital audio tracks to a pair of balanced analog outputs.

• High Performance 24bit/96kHz digital audio converter
• Plug & Play, no drivers required
• 3.5mm headphone output to test signals
• Balanced XLR outputs to feed a mixer or PA

Connect your laptop to a pro audio system

Whether you are playing backing tracks on stage, giving an audio presentation, or performing the role of DJ at an event, the USB-Pro is the easiest way to provide a high quality noise-free connection between a laptop and any sound system. Made for plug and play simplicity, the USB-Pro will automatically be listed as an available sound card in the audio settings of all popular operating systems including Windows and Mac, with 24bit/96kHz digital to analog converters that retain the quality of the audio signal. A stereo pair of balanced XLR outputs allows you to connect to a microphone preamplifier, PA system, mixing console, or even a powered speaker, with an on-board level control for quick and easy volume adjustments. Should any noise be encountered, ground lift switches are provided and isolation transformers can be inserted into the signal path to eliminate hum and buzz from ground loops, for a clean connection to the PA.

The Headlight is a unity gain guitar amp selector designed to easily integrate onto a pedalboard and provide the ability to switch between as many as four amplifiers with a single footswitch.

• Four output amp switcher with sequential switching
• Isolated outputs to eliminate hum and buzz
• Compact footprint easily fits on a pedalboard
• Mute footswitch for silent on-stage tuning

Small Size, Big Tone

The Headlight has a compact footprint that will fit on any pedalboard, but it's still powerful enough to drive up to four amplifiers without sacrificing on tone. The input features a class-A buffer along with Drag Control load correction that allows you to optimize the impedance for your pickups and recreate the feel of plugging your guitar directly into an amp. Custom transformers isolate the outputs to prevent buzz and hum from ground loops, with ground lift switches to further alleviate noise problems. Should you really want to get loud, the mute footswitch can be configured as an 'all on' switch, activating all four amp outputs simultaneously.

Driving four different amps on stage

Use the Headlight to switch between four stage amps to create the ultimate setup for clean, crunch, overdrive and power solo! Simply depress the selector footswitch to select the amp you want. Super bright LEDs let you know which amp is active. Use the mute footswitch for quiet on-stage tuning.

Using the Headlight as an ABY

Connect your two amps using outputs 1 and 2 and select between them using the right-hand footswitch. Set the left-hand footswitch to ALL-ON and when depressed, both amps will play. The isolation transformers will prevent buzz and hum from ground loops when both amps are on.

Using Headlight with DI Boxes and Amplifiers

Using the Headlight you can feed both direct boxes and amplifiers. The outputs from the direct boxes can be sent directly to the mixer and stage amps can be mic'd.
